Mr. John M. Hall, with whom Mr. Oscar Lawler was on the brief; Mr. Lewis B. Binford, with whom Mr. Thomas S. Tobin was on the brief; Mr. Edward L. Compton, with whom Mr. H.S. Mac Kay, Jr., was on the brief; and Mr. T.B. Cosgrove, with whom Mr. John N. Cramer was on the brief, — for respondents in Nos. 336, 337, 338, and 339, respectively.

Mr. Arthur W.A. Cowan filed a brief on behalf of the International Printing Pressmen & Assistants' Union, as amicus curiae, in support of petitioner.

MR. JUSTICE RUTLEDGE delivered the opinion of the Court.

These cases arise from the refusal of respondents, publishers of four Los Angeles daily newspapers, to bargain collectively with a union representing newsboys who distribute their papers on the streets of that city. Respondents' contention that they were not required to bargain because the newsboys are not their "employees" within the meaning of that term in the National Labor Relations Act, 49 Stat. 450, 29 U.S.C. § 152,[2] presents the important question which we granted certiorari[3] to resolve.

[114] The proceedings before the National Labor Relations Board were begun with the filing of four petitions for investigation and certification[4] by Los Angeles Newsboys Local Industrial Union No. 75. Hearings were held in a consolidated proceeding[5] after which the Board made findings of fact and concluded that the regular full-time newsboys selling each paper were employees within the Act and that questions affecting commerce concerning the representation of employees had arisen. It designated appropriate units and ordered elections. 28 N.L.R.B. 1006.[6] At these the union was selected as their representative by majorities of the eligible newsboys. After the union was appropriately certified, 33 N.L.R.B. 941, 36 N.L.R.B. 285, the respondents refused to bargain with it. Thereupon proceedings under § 10, 49 Stat. 453-455, 29 U.S.C. § 160, were instituted, a hearing[7] was held and respondents were found to have violated §§ 8 (1) and 8 (5) of the Act, 49 Stat. 452-453, 29 U.S.C. § 158 (1), (5). They were ordered to cease and desist from such violations and to bargain collectively with the union upon request. 39 N.L.R.B. 1245, 1256.

Upon respondents' petitions for review and the Board's petitions for enforcement, the Circuit Court of Appeals, one judge dissenting, set aside the Board's orders. Rejecting [115] the Board's analysis, the court independently examined the question whether the newsboys are employees within the Act, decided that the statute imports common-law standards to determine that question, and held the newsboys are not employees. 136 F.2d 608.

The findings of the Board disclose that the Los Angeles Times and the Los Angeles Examiner, published daily and Sunday,[8] are morning papers. Each publishes several editions which are distributed mn the streets during the evening before their dateline, between about 6:00 or 6:30 p.m. and 1:00 a.m., and other editions distributed during the following morning until about 10:00 o'clock. The Los Angeles Evening Herald and Express, published every day but Sunday, is an evening paper, which has six editions on the presses between 9:00 a.m. and 5:30 p. m.[9] The News, also published every day but Sunday, is a twenty-four hour paper with ten editions.[10]

The papers are distributed to the ultimate consumer through a variety of channels, including independent dealers and newsstands often attached to drug, grocery or confectionery stores, carriers who make home deliveries, and newsboys who sell on the streets of the city and its suburbs. Only the last of these are involved in this case.

The newsboys work under varying terms and conditions. They may be "bootjackers," selling to the general public at places other than established corners, or they may sell [116] at fixed "spots." They may sell only casually or part-time, or full-time; and they may be employed regularly and continuously or only temporarily. The units which the Board determined to be appropriate are composed of those who sell full-time at established spots. Those vendors, misnamed boys, are generally mature men, dependent upon the proceeds of their sales for their sustenance, and frequently supporters of families. Working thus as news vendors on a regular basis, often for a number of years, they form a stable group with relatively little turnover, in contrast to schoolboys and others who sell as bootjackers, temporary and casual distributors.

Over-all circulation and distribution of the papers are under the general qupervision of circulation managers. But for purposes of street distribution each paper has divided metropolitan Los Angeles into geographic districts. Each district is under the direct and close supervision of a district manager. His function in the mechanics of distribution is to supply the newsboys in his district with papers which he obtains from the publisher and to turn over to the publisher the receipts which he collects from their sales, either directly or with the assistance of "checkmen" or "main spot" boys.[11] The latter, stationed at the important corners or "spots" in the district, are newsboys who, among other things, receive delivery of the papers, redistribute them to other newsboys stationed at less important corners, and collect receipts from their sales.[12] For that service, which occupies a minor portion [117] of their working day, the checkmen receive a small salary from the publisher.[13] The bulk of their day, however, they spend in hawking papers at their "spots" like other full-time newsboys. A large part of the appropriate units selected by the Board for the News and the Herald are checkmen who, in that capacity, clearly are employees of those papers.

The newsboys' compensation consists in the difference between the prices at which they sell the papers and the prices they pay for them. The former are fixed by the publishers and the latter are fixed either by the publishers or, in the case of the News, by the district manager.[14] In practice the newsboys receive their papers on credit. They pay for those sold either sometime during or after the close of their selling day, returning for credit all unsold papers.[15] Lost or otherwise unreturned papers, however, must be paid for as though sold. Not only is the "profit" per paper thus effectively fixed by the publisher, but substantial control of the newsboys' total "take home" can be effected through the ability to designate their sales areas and the power to determine the number of papers allocated to each. While as a practical matter this power is not exercised fully, the newsboys' "right" to decide how many papers they will take is also not absolute. In practice, the Board found, they cannot determine the size of their established order without the cooperation of the district manager. And often the number of papers they must take is determined unilaterally by the district managers.

In addition to effectively fixing the compensation, respondents in a variety of ways prescribe, if not the [118] minutiae of daily activities, at least the broad terms and conditions of work. This is accomplished largely through the supervisory efforts of the district managers, who serve as the nexus between the publishers and the newsboys.[16] The district managers assign "spots" or corners to which the newsboys are expected to confine their selling activities.[17] Transfers from one "spot" to another may be ordered by the district manager for reasons of discipline or efficiency or other cause. Transportation to the spots from the newspaper building is offered by each of respondents. Hours of work on the spots are determined not simply by the impersonal pressures of the market, but to a real extent by explicit instructions from the district managers. Adherence to the prescribed hours is observed closely by the district managers or other supervisory agents of the publishers. Sanctions, varying in severity [119] from reprimand to dismissal, are visited on the tardy and the delinquent. By similar supervisory controls minimum standards of diligence and good conduct while at work are sought to be enforced. However wide may be the latitude for individual initiative beyond those standards, district managers' instructions in what the publishers apparently regard as helpful sales technique are expected to be followed. Such varied items as the manner of displaying the paper, of emphasizing current features and headlines, and of placing advertising placards, or the advantages of soliciting customers at specific stores or in the traffic lanes are among the subjects of this instruction. Moreover, newsboys are furnished with sales equipment, such as racks, boxes and change aprons, and advertising placards by the publishers. In this pattern of employment the Board found that the newsboys are an integral part of the publishers' distribution system and circulation organization. And the record discloses that the newsboys and checkmen feel they are employees of the papers; and respondents' supervisory employees, if not respondents themselves, regard them as such.

In addition to questioning the sufficiency of the evidence to sustain these findings, respondents point to a number of other attributes characterizing their relationship with the newsboys[18] and urge that on the entire [120] record the latter cannot be considered their employees. They base this conclusion on the argument that by common-law standards the extent of their control and direction of the newsboys' working activities creates no more than an "independent contractor" relationship and that common-law standards determine the "employee" relationship under the Act. They further urge that the Board's selection of a collective bargaining unit is neither appropriate nor supported by substantial evidence.[19]

I.

The principal question is whether the newsboys are "employees." Because Congress did not explicitly define the term, respondents say its meaning must be determined by reference to common-law standards. In their view "common-law standards" are those the courts have applied in distinguishing between "employees" and "independent contractors" when working out various problems unrelated to the Wagner Act's purposes and provisions.

The argument assumes that there is some simple, uniform and easily applicable test which the courts have used, in dealing with such problems, to determine whether persons doing work for others fall in one class or the other. Unfortunately this is not true. Only by a long and tortuous history was the simple formulation worked out which has been stated most frequently as "the test" for deciding whether one who hires another is responsible in tort for his wrongdoing.[20] But this formula has been by no means [121] exclusively controlling in the solution of other problems. And its simplicity has been illusory because it is more largely simplicity of formulation than of application. Few problems in the law have given greater variety of application and conflict in results than the cases arising in the borderland between what is clearly an employer-employee relationship and what is clearly one of independent, entrepreneurial dealing.[21] This is true within the limited field of determining vicarious liability in tort. It becomes more so when the field is expanded to include all of the possible applications of the distinction.

It is hardly necessary to stress particular instances of these variations or to emphasize that they have arisen principally, first, in the struggle of the courts to work out common-law liabilities where the legislature has given no guides for judgment,[22] more recently also under statutes which have posed the same problem for solution in the light of the enactment's particular terms and purposes.[23] [122] It is enough to point out that, with reference to an identical problem, results may be contrary over a very considerable region of doubt in applying the distinction, depending upon the state or jurisdiction where the determination is made;[24] and that within a single jurisdiction a person who, for instance, is held to be an "independent contractor" for the purpose of imposing vicarious liability in tort may be an "employee" for the purposes of particular legislation, quch as unemployment compensation. See, e.g., Globe Grain & Milling Co. v. Industrial Comm'n, 98 Utah 36, 91 P.2d 512. In short, the assumed simplicity and uniformity, resulting from application of "common-law standards," does not exist.

Mere reference to these possible variations as characterizing the application of the Wagner Act in the treatment of persons identically situated in the facts surrounding their employment and in the influences tending to disrupt it, would be enough to require pause before accepting a thesis which would introduce them into its administration. This would be true, even if the statute itself had indicated less clearly than it does the intent they should not apply.

Two possible consequences could follow. One would be to refer the decision of who are employees to local state law. The alternative would be to make it turn on a sort of pervading general essence distilled from state law. Congress obviously did not intend the former result. It [123] would introduce variations into the statute's operation as wide as the differences the forty-eight states and other local jurisdictions make in applying the distinction for wholly different purposes. Persons who might be "employees" in one state would be "independent contractors" in another. They would be within or without the statute's protection depending not on whether their situation falls factually within the ambit Congress had in mind, but upon the accidents of the location of their work and the attitude of the particular local jurisdiction in casting doubtful cases one way or the other. Persons working across state lines might fall in one class or the other, possibly both, depending on whether the Board and the courts would be required to give effect to the law of one state or of the adjoining one, or to that of each in relation to the portion of the work done within its borders.

Both the terms and the purposes of the statute, as well as the legislative history, show that Congress had in mind no such patchwork plan for securing freedom of employees' organization and of collective bargaining. The Wagner Act is federal legislation, administered by a national agency intended to solve a national problem on a national scale. Cf. e.g., Sen. Rep. No. 573, 74th Cong., 1st Sess. 2-4. It is an Act, therefore, in reference to which it is not only proper but necessary for us to assume, "in the absence of a plain indication to the contrary, that Congress . . . is not making the application of the federal act dependent on state law." Jerome v. United States, 318 U.S. 101, 104. Nothing in the statute's background, history, terms or purposes indicates its scope is to be limited by such varying local conceptions, either statutory or judicial, or that it is to be administered in accordance with whatever different standards the respective states may see fit to adopt for the disposition of unrelated, local problems. Consequently, so far as the meaning of "employee" in this statute is concerned, "the federal law must prevail no matter what name is given to the interest or [124] right by state law." Morgan v. Commissioner, 309 U.S. 78, 81; cf. Labor Board v. Blount, 131 F.2d 585 (C.C.A.).

II.

Whether, given the intended national uniformity, the term "employee" includes such workers as these newsboys must be answered primarily from the history, terms and purposes of the legislation. The word "is not treated by Congress as a word of art having a definite meaning. . . ." Rather "it takes color from its surroundings . . . [in] the statute where it appears," United States v. American Trucking Assns., 310 U.S. 534, 545, and derives meaning from the context of that statute, which "must be read in the light of the mischief to be corrected and the end to be attained." South Chicago Coal & Dock Co. v. Bassett, 309 U.S. 251, 259; cf. New Negro Alliance v. Sanitary Grocery Co., 303 U.S. 552; Drivers' Union v. Lake Valley Co., 311 U.S. 91.

Congress, on the one hand, was not thinking solely of the immediate technical relation of employer and employee. It had in mind at least some other persons than those standing in the proximate legal relation of employee to the particular employer involved in the labor dispute.[25] It cannot be taken, however, that the purpose was to include all other persons who may perform service for another or was to ignore entirely legal classifications made for other purposes. Congress had in mind a wider field than the narrow technical legal relation of "master and servant," as the common law had worked this out in all its variations, and at the same time a narrower one than the entire area of rendering service to others. The question comes down therefore to how much was included of the intermediate [125] region between what is clearly and unequivocally "employment," by any appropriate test, and what is as clearly entrepreneurial enterprise and not employment.

It will not do, for deciding this question as one of uniform national application, to import wholesale the traditional common-law conceptions or some distilled essence of their local variations as exclusively controlling limitations upon the scope of the statute's effectiveness. To do this would be merely to select some of the local, hairline variations for nation-wide application and thus to reject others for coverage under the Act. That result hardly would be consistent with the statute's broad terms and purposes.

Congress was not seeking to solve the nationally harassing problems with which the statute deals by solutions only partially effective. It rather sought to find a broad solution, one that would bring industrial peace by substituting, so far as its power could reach, the rights of workers to self-organization and collective bargaining for the industrial strife which prevails where these rights are not effectively established. Yet only partial solutions would be provided if large segments of workers about whose technical legal position such local differences exist should be wholly excluded from coverage by reason of such differences. Yet that result could not be avoided, if choice must be made among them and controlled by them in deciding who are "employees" within the Act's meaning. Enmeshed in such distinctions, the administration of the statute soon might become encumbered by the same sort of technical legal refinement as has characterized the long evolution of the employee - independent contractor dichotomy in the courts for other purposes. The consequences would be ultimately to defeat, in part at least, the achievement of the statute's objectives. Congress no more intended to [126] import this mass of technicality as a controlling "standard" for uniform national application than to refer decision of the question outright to the local law.

The Act, as its first section states, was designed to avert the "substantial obstructions to the free flow of commerce" which result from "strikes and other forms of industrial strife or unrest" by eliminating the causes of that unrest. It is premised on explicit findings that strikes and industrial strife themselves result in large measure from the refusal of employers to bargain collectively and the inability of individual workers to bargain successfully for improvements in their "wages, hours or other working conditions" with employers who are "organized in the corporate or other forms of ownership association." Hence the avowed and interrelated purposes of the Act are to encourage collective bargaining and to remedy the individual worker's inequality of bargaining power by "protecting the exercise . . . of full freedom of association, self-organization, and designation of representatives of their own choosing, for the purpose of negotiating the terms and conditions of their employment or other mutual aid or protection." 49 Stat. 449, 450.

The mischief at which the Act is aimed and the remedies it offers are not confined exclusively to "employees" within the traditional legal distinctions separating them from "independent contractors." Myriad forms of service relationship, with infinite and subtle variations in the terms of employment, blanket the nation's economy. Some are within this Act, others beyond its coverage. Large numbers will fall clearly on one side or on the other, by whatever test may be applied. But intermediate there will be many, the incidents of whose employment partake in part of the one group, in part of the other, in varying proportions of weight. And consequently the legal pendulum, for purposes of applying the statute, may swing one way [127] or the other, depending upon the weight of this balance and its relation to the special purpose at hand.

Unless the common-law tests are to be imported and made exclusively controlling, without regard to the statute's purposes, it cannot be irrelevant that the particular workers in these cases are subject, as a matter of economic fact, to the evils the statute was designed to eradicate and that the remedies it affords are appropriate for preventing them or curing their harmful effects in the special situation. Interruption of commerce through strikes and unrest may stem as well from labor disputes between some who, for other purposes, are technically "independent contractors" and their employers as from disputes between persons who, for those purposes, are "employees" and their employers. Cf. Drivers' Union v. Lake Valley Co., 311 U.S. 91. Inequality of bargaining power in controversies over wages, hours and working conditions may as well characterize the status of the one group as of the other. The former, when acting alone, may be as "helpless in dealing with an employer," as "dependent . . . on his daily wage" and as "unable to leave the employ and to resist arbitrary and unfair treatment" as the latter. For each, "union . . . [may be] essential to give . . . opportunity to deal on equality with their employer."[26] And for each, collective bargaining may be appropriate and effective for the "friendly adjustment of industrial disputes arising out of differences as to wages, hours, or other working conditions."[27] 49 Stat. 449. In [128] short, when the particular situation of employment combines these characteristics, so that the economic facts of the relation make it more nearly one of employment than of independent business enterprise with respect to the ends sought to be accomplished by the legislation, those characteristics may outweigh technical legal classification for purposes unrelated to the statute's objectives and bring the relation within its protections.

To eliminate the causes of Labor disputes and industrial strife, Congress thought it necessary to create a balance of forces in certain types of economic relationships. These do not embrace simply employment associations in which controversies could be limited to disputes over proper "physical conduct in the performance of the service."[28] On the contrary, Congress recognized those economic relationships cannot be fitted neatly into the containers designated "employee" and "employer" which an earlier law had shaped for different purposes. Its Reports on the bill disclose clearly the understanding that "employers and employees not in proximate relationship may be drawn into common controversies by economic forces,"[29] and that the very disputes sought to be avoided might involve [129] "employees [who] are at times brought into an economic relationship with employers who are not their employers."[30] In this light, the broad language of the Act's definitions, which in terms reject conventional limitations on such conceptions as "employee," "employer," and "labor dispute,"[31] leaves no doubt that its applicability is to be determined broadly, in doubtful situations, by underlying economic facts rather than technically and exclusively by previously established legal classifications. Cf. Labor Board v. Blount, supra.

Hence "technical concepts pertinent to an employer's legal responsibility to third persons for acts of his servants" have been rejected in various applications of this Act both here (International Association of Machinists v. Labor Board, 311 U.S. 72, 80-81; H.J. Heinz Co. v. Labor Board, 311 U.S. 514, 520-521)[32] and in other federal courts (Labor Board v. Condenser Corp., 128 F.2d 67 (C.C.A.); North Whittier Heights Citrus Assn. v. Labor Board, 109 F.2d 76, 82 (C.C.A.); Labor Board v. Blount, supra). There is no good reason for invoking them to restrict the scope of the term "employee" sought to be done in this case. That term, like other provisions, must be understood with reference to the purpose of the Act and the facts involved in the economic relationship.[33] "Where all the conditions of the relation require protection, protection ought to be given."[34]

[130] It is not necessary in this case to make a completely definitive limitation around the term "employee." That task has been assigned primarily to the agency created by Congress to administer the Act. Determination of "where all the conditions of the relation require protection" involves inquiries for the Board charged with this duty. Everyday experience in the administration of the statute gives it familiarity with the circumstances and backgrounds of employment relationships in various industries, with the abilities and needs of the workers for self-organization and collective action, and with the adaptability of collective bargaining for the peaceful settlement of their disputes with their employers. The experience thus acquired must be brought frequently to bear on the question who is an employee under the Act. Resolving that question, like determining whether unfair labor practices have been committed, "belongs to the usual administrative routine" of the Board.[35] Gray v. Powell, 314 U.S. 402, 411. Cf. Labor Board v. Standard Oil Co., 138 F.2d 885, 887-888.

In making that body's determinations as to the facts in these matters conclusive, if supported by evidence, Congress entrusted to it primarily the decision whether the evidence establishes the material facts. Hence in reviewing the Board's ultimate conclusions, it is not the court's function to substitute its own inferences of fact for the Board's, when the latter have support in the record. Labor Board v. Nevada Copper Corp., 316 U.S. 105; cf. Walker v. Altmeyer, 137 F.2d 531 (C.C.A.). Undoubtedly questions of statutory interpretation, especially when arising in the first instance in judicial proceedings, are for [131] the courts to resolve, giving appropriate weight to the judgment of those whose special duty is to administer the questioned statute. Norwegian-Nitrogen Products Co. v. United States, 288 U.S. 294; United States v. American Trucking Assns., 310 U.S. 534. But where the question is one of specific application of a broad statutory term in a proceeding in which the agency administering the statute must determine it initially, the reviewing court's function is limited. Like the commissioner's determination under the Longshoremen's & Harbor Workers' Act,[36] that a man is not a "member of a crew" (South Chicago Coal & Dock Co. v. Bassett, 309 U.S. 251) or that he was injured "in the course of employment" (Parker v. Motor Boat Sales, 314 U.S. 244) and the Federal Communications Commission's determination[37] that one company is under the "control" of another (Rochester Telephone Corp. v. United States, 307 U.S. 125), the Board's determination that specified persons are "employees" under this Act is to be accepted if it has "warrant in the record" and a reasonable basis in law.

In this case the Board found that the designated newsboys work continuously and regularly, rely upon their earnings for the support of themselves and their families, and have their total wages influenced in large measure by the publishers, who dictate their buying and selling prices, fix their markets and control their supply of papers. Their hours of work and their efforts on the job are supervised and to some extent prescribed by the publishers or their agents. Much of their sales equipment and advertising materials is furnished by the publishers with the intention that it be used for the publisher's benefit. Stating that "the primary consideration in the determination of the applicability of the statutory definition is whether [132] effectuation of the declared policy and purposes of the Act comprehend securing to the individual the rights guaranteed and protection afforded by the Act," the Board concluded that the newsboys are employees. The record sustains the Board's findings and there is ample basis in the law for its conclusion.

III.

The Board's selection of the collective bargaining units also must be upheld. The units chosen for the News and the Herald consist of all full-time[38] newsboys and checkmen engaged to sell the papers in Los Angeles. Bootjackers, temporary, casual and part-time[39] newsboys are excluded. The units designated for the Times and the Examiner consist of newsboys selling at established spots[40] in Los Angeles[41] four or more hours per day five or more days per week, except temporary newsboys.[42]

The Board predicated its designations in part upon the finding that the units included, in general, men who were responsible workers, continuously and regularly employed as vendors and dependent upon their sales for their livelihood, [133] while schoolboys and transient or casual workers were excluded. The discretion which Congress vested in the Board to determine an appropriate unit is hardly overstepped by the choice of a unit based on a distinction so clearly consistent with the need for responsible bargaining. That the Board's selection emphasizes difference in tenure rather than function is, on this record certainly, no abuse of discretion.

Nor is there substance in the objection that the Board's designations on the one hand fail to embrace all workers who in fact come within the responsible or stable full-time category generically stated, and on the other hand fail to exclude all who in fact come within the schoolboy or more volatile part-time category. The record does not suggest that the units designated, at least so far as Los Angeles newsboys are concerned, do not substantially effectuate the Board's theory or embrace a large portion of those who would make up a stable bargaining group based on responsible tenure and full-time work. In these matters the Board cannot be held to mathematical precision. If it chooses to couch its orders in terms which for good reasons it regards effective to accomplish its stated ends, peripheral or hypothetical deviations will not defeat an otherwise appropriate order.

Another objection urged by the Times, the Herald and the Examiner is to the Board's exclusion of suburban newsboys[43] from the units on the ground they were not organized by the union. The Board found that although all vendors in metropolitan Los Angeles were eligible for membership, the union had not been extended to the suburban groups generally and that no other labor organization was seeking to represent respondents' employees. There is no suggestion either that the union deliberately [134] excluded suburban newsboys who sought admission or that suburban newsboys have displayed any interest in collective bargaining or self-organization.

Wide variations in the forms of employee self-organization and the complexities of modern industrial organization make difficult the use of inflexible rules as the test of an appropriate unit. Congress was informed of the need for flexibility in shaping the unit to the particular case[44] and accordingly gave the Board wide discretion in the matter. Its choice of a unit is limited specifically only by the requirement that it be an "employer unit, craft unit, plant unit, or subdivision thereof" and that the selection be made so as "to insure to employees the full benefit of their right to self-organization and to collective bargaining, and otherwise to effectuate the policies of the Act." Pittsburgh Plate Glass Co. v. Labor Board, 313 U.S. 146. The flexibility which Congress thus permitted has characterized the Board's administration of the section and has led it to resort to a wide variety of factors in case-to-case determination of the appropriate unit.[45] Among the considerations to which it has given weight is the extent of organization of the union requesting certification or collective bargaining. This is done on the expressed theory that it is desirable in the determination of an appropriate unit to render collective bargaining of the company's employees an immediate possibility.[46] No [135] plausible reason is suggested for withholding the benefits of the Act from those here seeking it until a group of geographically separated employees becomes interested in collective bargaining. In the circumstances disclosed by this record we cannot say the Board's conclusions are lacking in a "rational basis."

The judgments are reversed and the causes are remanded for further proceedings not inconsistent with this opinion.

Reversed.

MR. JUSTICE REED concurs in the result. He is of the opinion that the test of coverage for employees is that announced by the Board in the matter of Stockholders Publishing Company, Inc., and Los Angeles Newsboys Local Industrial Union No. 75, C.I.O., and other similar cases, decided January 9, 1941, 28 N.L.R.B. 1006, 1022-23.

MR. JUSTICE ROBERTS:

I think the judgment of the Circuit Court of Appeals should be affirmed. The opinion of that court reported in 136 F.2d 608, seems to me adequately to state the controlling facts and correctly to deal with the question of law presented for decision. I should not add anything were it not for certain arguments presented here and apparently accepted by the court.

I think it plain that newsboys are not "employees" of the respondents within the meaning and intent of the National Labor Relations Act. When Congress, in § 2 (3), said "The term `employee' shall include any employee, . . ." it stated as clearly as language could do it that the provisions of the Act were to extend to those who, as a result of decades of tradition which had become part of the common understanding of our people, bear the named relationship. Clearly also Congress did not delegate [136] to the National Labor Relations Board the function of defining the relationship of employment so as to promote what the Board understood to be the underlying purpose of the statute. The question who is an employee, so as to make the statute applicable to him, is a question of the meaning of the Act and, therefore, is a judicial and not an administrative question.

I do not think that the court below suggested that the federal courts sitting in the various states must determine whether a given person is an employee by application of either the local statutes or local state decisions. Quite the contrary. As a result of common law development, many prescriptions of federal statutes take on meaning which is uniformly ascribed to them by the federal courts, irrespective of local variance. Funk v. United States, 290 U.S. 371. This court has repeatedly resorted to just such considerations in defining the very term "employee" as used in other federal statutes, as the opinion of the court below shows. There is a general and prevailing rule throughout the Union as to the indicia of employment and the criteria of one's status as employee. Unquestionably it was to this common, general, and prevailing understanding that Congress referred in the statute and, according to that understanding, the facts stated in the opinion below, and in that of this court, in my judgment, demonstrate that the newsboys were not employees of the newspapers.

It is urged that the Act uses the term in some loose and unusual sense such as justifies the Board's decision because Congress added to the definition of employee above quoted these further words: "and shall not be limited to the employees of a particular employer, unless the Act explicitly states otherwise,. . ." The suggestion seems to be that Congress intended that the term employee should mean those who were not in fact employees, but it [137] is perfectly evident, not only from the provisions of the Act as a whole but from the Senate Committee's Report, that this phrase was added to prevent any misconception of the provisions whereby employees were to be allowed freely to combine and to be represented in collective bargaining by the representatives of their union. Congress intended to make it clear that employee organizations did not have to be organizations of the employees of any single employer. But that qualifying phrase means no more than this and was never intended to permit the Board to designate as employees those who, in traditional understanding, have no such status.

Hearst Publications, Inc., and No. 339, National Labor Relations Board v. Times-Mirror Co., also on writs of certiorari to the Circuit Court of Appeals for the Ninth Circuit.

[2] Section 2 (3) of the Act provides that "The term `employee' shall include any employee, and shall not be limited to the employees of a particular employer, unless the Act explicitly states otherwise, and shall include any individual whose work has ceased as a consequence of, or in connection with, any current labor dispute or because of any unfair labor practice, and who has not obtained any other regular and substantially equivalent employment, but shall not include any individual employed as an agricultural laborer, or in the domestic service of any family or person at his home, or any individual employed by his parent or spouse."

[4] Pursuant to § 9 (b) and (c) of the Act; 49 Stat. 451, 29 U.S.C. § 159 (b) and (c).

[5] Although it treated the four representation petitions in one consolidated proceeding and disposed of them in one opinion, the Board did not consider evidence with respect to one publisher as applicable to any of the others.

[6] Subsequently those orders were amended in various details. 29 N.L.R.B. 94, 95; 30 N.L.R.B. 696, 697; 31 N.L.R.B. 697.

[7] The record in the representation proceeding was in effect incorporated in the complaint proceeding.

[8] The Times' daily circulation is about 220,000 and its Sunday circulation is about 368,000. The Examiner's daily circulation is about 214,000 and its Sunday circulation is about 566,000.

[9] The Herald has a circulation of about 243,000. Both it and the Examiner are owned by Hearst Publications, Inc.

[10] The News has a circulation of about 195,000. Its first three and seventh editions are consigned for the most part to route delivery or suburban dealers. Its fourth edition, which goes to press at 2:45 a.m., is sold in the city during the mornings. The remaining editions, which go to press at regular intervals between 9:50 a.m. and 5:00 p.m., are sold in the city during the afternoons.

[11] The Examiner, the Herald, and the News all employ "main spot" boys or checkmen; the Times does not.

[12] The Times district managers deliver the papers directly to the newsboys and collect directly from them. On the other papers district managers may deliver bundles of papers to the checkmen or directly to the newsboys themselves. The Times customarily transports its newsboys to their "spots" from the Times building, where they first report and pick up their papers. The other respondents offer similar transportation to those of their newsboys who desire it.

[13] In the case of the Examiner these "main spot" boys, although performing services similar to those of checkmen, are less closely knit to the publisher and sometimes receive no compensation for their services.

[14] See infra, note 15.

[15] Newsboys selling the Herald in one residential area do not receive credit for all unsold papers.

[16] Admittedly the Times, Examiner, and Herald district managers are employees of their respective papers. While the News urged earnestly that its managers are not its employees, the Board found otherwise. They do not operate on a formal salary basis but they receive guaranteed minimum payments which the Board found are "no more than a fixed salary bearing another label." And while they, rather than the publisher, fix the price of the paper to the newsboy, the Board found, on substantial evidence, that they function for the News in specified districts, distribute racks, aprons, advertising placards from the News to the newsboys, give instructions as to their use, supervise the redistributing activities of the checkmen (themselves clearly employees of the News), and hand out News checks to the checkmen for their services. On this and other evidence suggesting that however different may be their formal arrangements, News district managers bear substantially the same relation to the publisher on one hand and the newsboys on the other as do the other district managers, the Board concluded that they were employees of the paper.

[17] Although from time to time these "spots" are bought and sold among the vendors themselves, without objection by district managers and publishers, this in no way negates the need for the district managers' implicit approval of a spotholder or their authority to remove vendors from their "spots" for reasons of discipline or efficiency.

[18] E.g., that there is either no evidence in the record to show, or the record explicitly negatives, that respondents carry the newsboys on their payrolls, pay "salaries" to them, keep records of their sales or locations, or register them as "employees" with the Social Security Board, or that the newsboys are covered by workmen's compensation insurance or the California Compensation Act. Furthermore, it is urged the record shows that the newsboys all sell newspapers, periodicals and other items not furnished to them by their respective publishers, assume the risk for papers lost, stolen or destroyed, purchase and sell their "spots," hire assistants and relief men and make arrangements among themselves for the sale of competing or leftover papers.

[19] They have abandoned here the contention, made in the circuit court, that the Act does not reach their controversies with the newsboys because they do not affect commerce.

[20] The so-called "control test" with which common-law judges have wrestled to secure precise and ready applications did not escape the difficulties encountered in borderland cases by its reformulation in the Restatement of the Law of Agency § 220. That even at the common law the control test and the complex of incidents evolved in applying it to distinguish an "employee" from an "independent contractor," for purposes of vicarious liability in tort, did not necessarily have the same significance in other contexts, compare Lumley v. Gye [1853] El. & Bl. 216, and see also the cases collected in 21 A.L.R. 1229 et seq.; 23 A.L.R. 984 et seq.

CERTIORARI TO THE CIRCUIT COURT OF APPEALS FOR THE FIFTH CIRCUIT.

[135] Mr. R. Curtis McBroom, with whom Mr. Mark McGee was on the brief, for petitioners.

Mr. Beverley V. Thompson, with whom Mr. Wm. N. Strack was on the brief, for respondent.

Solicitor General Fahy, Mr. Douglas B. Maggs, and Miss Bessie Margolin filed a brief on behalf of the Administrator of the Wage and Hour Division, U.S. Department of Labor, as amicus curiae, urging reversal.

MR. JUSTICE JACKSON delivered the opinion of the Court.

Seven employees of the Swift and Company packing plant at Fort Worth, Texas, brought an action under the Fair Labor Standards Act to recover overtime, liquidated damages, and attorneys' fees, totalling approximately $77,000. The District Court rendered judgment denying this claim wholly, 53 F. Supp. 1020, and the Circuit Court of Appeals for the Fifth Circuit affirmed. 136 F.2d 112.

It is not denied that the daytime employment of these persons was working time within the Act. Two were engaged in general fire-hall duties and maintenance of fire-fighting equipment of the Swift plant. The others operated elevators or acted as relief men in fire duties. They worked from 7:00 a.m. to 3:30 p.m., with a half-hour lunch period, five days a week. They were paid weekly salaries.

Under their oral agreement of employment, however, petitioners undertook to stay in the fire hall on the Company premises, or within hailing distance, three and a half to four nights a week. This involved no task except to answer alarms, either because of fire or because the sprinkler was set off for some other reason. No fires occurred during the period in issue, the alarms were rare, and the time required for their answer rarely exceeded an hour. For each alarm answered the employees were [136] paid in addition to their fixed compensation an agreed amount, fifty cents at first, and later sixty-four cents. The Company provided a brick fire hall equipped with steam heat and air-conditioned rooms. It provided sleeping quarters, a pool table, a domino table, and a radio. The men used their time in sleep or amusement as they saw fit, except that they were required to stay in or close by the fire hall and be ready to respond to alarms. It is stipulated that "they agreed to remain in the fire hall and stay in it or within hailing distance, subject to call, in event of fire or other casualty, but were not required to perform any specific tasks during these periods of time, except in answering alarms." The trial court found the evidentiary facts as stipulated; it made no findings of fact as such as to whether under the arrangement of the parties and the circumstances of this case, which in some respects differ from those of the Armour case (ante, p. 126), the fire-hall duty or any part thereof constituted working time. It said, however, as a "conclusion of law" that "the time plaintiffs spent in the fire hall subject to call to answer fire alarms does not constitute hours worked, for which overtime compensation is due them under the Fair Labor Standards Act, as interpreted by the Administrator and the Courts," and in its opinion observed, "of course we know pursuing such pleasurable occupations or performing such personal chores, does not constitute work." The Circuit Court of Appeals affirmed.

For reasons set forth in the Armour case decided herewith we hold that no principle of law found either in the statute or in Court decisions precludes waiting time from also being working time. We have not attempted to, and we cannot, lay down a legal formula to resolve cases so varied in their facts as are the many situations in which employment involves waiting time. Whether in a concrete case such time falls within or without the Act is a question of fact to be resolved by appropriate findings of the trial [137] court. Walling v. Jacksonville Paper Co., 317 U.S. 564, 572. This involves scrutiny and construction of the agreements between the particular parties, appraisal of their practical construction of the working agreement by conduct, consideration of the nature of the service, and its relation to the waiting time, and all of the surrounding circumstances. Facts may show that the employee was engaged to wait, or they may show that he waited to be engaged. His compensation may cover both waiting and task, or only performance of the task itself. Living quarters may in some situations be furnished as a facility of the task and in another as a part of its compensation. The law does not impose an arrangement upon the parties. It imposes upon the courts the task of finding what the arrangement was.

We do not minimize the difficulty of such an inquiry where the arrangements of the parties have not contemplated the problem posed by the statute. But it does not differ in nature or in the standards to guide judgment from that which frequently confronts courts where they must find retrospectively the effect of contracts as to matters which the parties failed to anticipate or explicitly to provide for.

Congress did not utilize the services of an administrative agency to find facts and to determine in the first instance whether particular cases fall within or without the Act. Instead, it put this responsibility on the courts. Kirschbaum Co. v. Walling, 316 U.S. 517, 523. But it did create the office of Administrator, impose upon him a variety of duties, endow him with powers to inform himself of conditions in industries and employments subject to the Act, and put on him the duties of bringing injunction actions to restrain violations. Pursuit of his duties has accumulated a considerable experience in the problems of ascertaining working time in employments involving periods of inactivity and a knowledge of the customs [138] prevailing in reference to their solution. From these he is obliged to reach conclusions as to conduct without the law, so that he should seek injunctions to stop it, and that within the law, so that he has no call to interfere. He has set forth his views of the application of the Act under different circumstances in an interpretative bulletin and in informal rulings. They provide a practical guide to employers and employees as to how the office representing the public interest in its enforcement will seek to apply it. Wage and Hour Division, Interpretative Bulletin No. 13.

The Administrator thinks the problems presented by inactive duty require a flexible solution, rather than the all-in or all-out rules respectively urged by the parties in this case, and his Bulletin endeavors to suggest standards and examples to guide in particular situations. In some occupations, it says, periods of inactivity are not properly counted as working time even though the employee is subject to call. Examples are an operator of a small telephone exchange where the switchboard is in her home and she ordinarily gets several hours of uninterrupted sleep each night; or a pumper of a stripper well or watchman of a lumber camp during the off season, who may be on duty twenty-four hours a day but ordinarily "has a normal night's sleep, has ample time in which to eat his meals, and has a certain amount of time for relaxation and entirely private pursuits." Exclusion of all such hours the Administrator thinks may be justified. In general, the answer depends "upon the degree to which the employee is free to engage in personal activities during periods of idleness when he is subject to call and the number of consecutive hours that the employee is subject to call without being required to perform active work." "Hours worked are not limited to the time spent in active labor but include time given by the employee to the employer. . . ."

[139] The facts of this case do not fall within any of the specific examples given, but the conclusion of the Administrator, as expressed in the brief amicus curiae, is that the general tests which he has suggested point to the exclusion of sleeping and eating time of these employees from the workweek and the inclusion of all other on-call time: although the employees were required to remain on the premises during the entire time, the evidence shows that they were very rarely interrupted in their normal sleeping and eating time, and these are pursuits of a purely private nature which would presumably occupy the employees' time whether they were on duty or not and which apparently could be pursued adequately and comfortably in the required circumstances; the rest of the time is different because there is nothing in the record to suggest that, even though pleasurably spent, it was spent in the ways the men would have chosen had they been free to do so.

There is no statutory provision as to what, if any, deference courts should pay to the Administrator's conclusions. And, while we have given them notice, we have had no occasion to try to prescribe their influence. The rulings of this Administrator are not reached as a result of hearing adversary proceedings in which he finds facts from evidence and reaches conclusions of law from findings of fact. They are not, of course, conclusive, even in the cases with which they directly deal, much less in those to which they apply only by analogy. They do not constitute an interpretation of the Act or a standard for judging factual situations which binds a district court's processes, as an authoritative pronouncement of a higher court might do. But the Administrator's policies are made in pursuance of official duty, based upon more specialized experience and broader investigations and information than is likely to come to a judge in a particular case. They do determine the policy which will guide applications for enforcement [140] by injunction on behalf of the Government. Good administration of the Act and good judicial administration alike require that the standards of public enforcement and those for determining private rights shall be at variance only where justified by very good reasons. The fact that the Administrator's policies and standards are not reached by trial in adversary form does not mean that they are not entitled to respect. This Court has long given considerable and in some cases decisive weight to Treasury Decisions and to interpretative regulations of the Treasury and of other bodies that were not of adversary origin.

We consider that the rulings, interpretations and opinions of the Administrator under this Act, while not controlling upon the courts by reason of their authority, do constitute a body of experience and informed judgment to which courts and litigants may properly resort for guidance. The weight of such a judgment in a particular case will depend upon the thoroughness evident in its consideration, the validity of its reasoning, its consistency with earlier and later pronouncements, and all those factors which give it power to persuade, if lacking power to control.

The courts in the Armour case weighed the evidence in the particular case in the light of the Administrator's rulings and reached a result consistent therewith. The evidence in this case in some respects, such as the understanding as to separate compensation for answering alarms, is different. Each case must stand on its own facts. But in this case, although the District Court referred to the Administrator's Bulletin, its evaluation and inquiry were apparently restricted by its notion that waiting time may not be work, an understanding of the law which we hold to be erroneous. Accordingly, the judgment is reversed and the cause remanded for further proceedings consistent herewith.

Reversed.

Justice Stevens

delivered the opinion of the Court.

In the Clean Air Act Amendments of 1977, Pub. L. 95-95, 91 Stat. 685, Congress enacted certain requirements appli*840cable to States that had not achieved the national air quality standards established by the Environmental Protection Agency (EPA) pursuant to earlier legislation. The amended Clean Air Act required these “nonattainment” States to establish a permit program regulating “new or modified major stationary sources” of air pollution. Generally, a permit may not be issued for a new or modified major stationary source unless several stringent conditions are met.1 The EPA regulation promulgated to implement this permit requirement allows a State to adopt a plantwide definition of the term “stationary source.”2 Under this definition, an existing plant that contains several pollution-emitting devices may install or modify one piece of equipment without meeting the permit conditions if the alteration will not increase the total emissions from the plant. The question presented by these cases is whether EPA’s decision to allow States to treat all of the pollution-emitting devices within the same industrial grouping as though they were encased within a single “bubble” is based on a reasonable construction of the statutory term “stationary source.”

I

The EPA regulations containing the plantwide definition of the term stationary source were promulgated on October *84114, 1981. 46 Fed. Reg. 50766. Respondents3 filed a timely petition for review in the United States Court of Appeals for the District of Columbia Circuit pursuant to 42 U. S. C. 17607(b)(1).4 The Court of Appeals set aside the regulations. National Resources Defense Council, Inc. v. Gorsuch, 222 U. S. App. D. C. 268, 685 F. 2d 718 (1982).

The court observed that the relevant part of the amended Clean Air Act “does not explicitly define what Congress envisioned as a ‘stationary source, to which the permit program . . . should apply,” and further stated that the precise issue was not “squarely addressed in the legislative history.” Id., at 273, 685 F. 2d, at 723. In light of its conclusion that the legislative history bearing on the question was “at best contradictory,” it reasoned that “the purposes of the non-attainment program should guide our decision here.” Id., at 276, n. 39, 685 F. 2d, at 726, n. 39.5 Based on two of its precedents concerning the applicability of the bubble concept to certain Clean Air Act programs,6 the court stated that the bubble concept was “mandatory” in programs designed merely to maintain existing air quality, but held that it was “inappropriate” in programs enacted to improve air quality. Id., at 276, 685 F. 2d, at 726. Since the purpose of the per*842mit program — its “raison d’Ure,” in the court’s view — was to improve air quality, the court held that the bubble concept was inapplicable in these cases under its prior precedents. Ibid. It therefore set aside the regulations embodying the bubble concept as contrary to law. We granted certiorari to review that judgment, 461 U. S. 956 (1983), and we now reverse.

The basic legal error of the Court of Appeals was to adopt a static judicial definition of the term “stationary source” when it had decided that Congress itself had not commanded that definition. Respondents do not defend the legal reasoning of the Court of Appeals.7 Nevertheless, since this Court reviews judgments, not opinions,8 we must determine whether the Court of Appeals’ legal error resulted in an erroneous judgment on the validity of the regulations.

HH H-(

When a court reviews an agency s construction of the statute which it administers, it is confronted with two questions. First, always, is the question whether Congress has directly spoken to the precise question at issue. If the intent of Congress is clear, that is the end of the matter; for the court, *843as well as the agency, must give effect to the unambiguously expressed intent of Congress.9 If, however, the court determines Congress has not directly addressed the precise question at issue, the court does not simply impose its own construction on the statute,10 as would be necessary in the absence of an administrative interpretation. Rather, if the statute is silent or ambiguous with respect to the specific issue, the question for the court is whether the agency’s answer is based on a permissible construction of the statute.11

“The power of an administrative agency to administer a congressionally created . . . program necessarily requires the formulation of policy and the making of rules to fill any gap left, implicitly or explicitly, by Congress.” Morton v. Ruiz, 415 U. S. 199, 231 (1974). If Congress has explicitly left a gap for the agency to fill, there is an express delegation *844of authority to the agency to elucidate a specific provision of the statute by regulation. Such legislative regulations are given controlling weight unless they are arbitrary, capricious, or manifestly contrary to the statute.12 Sometimes the legislative delegation to an agency on a particular question is implicit rather than explicit. In such a case, a court may not substitute its own construction of a statutory provison for a reasonable interpretation made by the administrator of an agency.13

We have long recognized that considerable weight should be accorded to an executive department’s construction of a statutory scheme it is entrusted to administer,14 and the principle of deference to administrative interpretations

“has been consistently followed by this Court whenever decision as to the meaning or reach of a statute has involved reconciling conflicting policies, and a full understanding of the force of the statutory policy in the given situation has depended upon more than ordinary knowledge respecting the matters subjected to agency regulations. See, e. g., National Broadcasting Co. v. United States, 319 U. S. 190; Labor Board v. Hearst Publications, Inc., 322 U. S. 111; Republic Aviation Corp. v. *845Labor Board, 324 U. S. 793; Securities & Exchange Comm’n v. Chenery Corp., 332 U. S. 194; Labor Board v. Seven-Up Bottling Co., 344 U. S. 344.
. . If this choice represents a reasonable accommodation of conflicting policies that were committed to the agency’s care by the statute, we should not disturb it unless it appears from the statute or its legislative history that the accommodation is not one that Congress would have sanctioned.” United States v. Shimer, 367 U. S. 374, 382, 383 (1961).

Accord, Capital Cities Cable, Inc. v. Crisp, ante, at 699-700.

In light of these well-settled principles it is clear that the Court of Appeals misconceived the nature of its role in reviewing the regulations at issue. Once it determined, after its own examination of the legislation, that Congress did not actually have an intent regarding the applicability of the bubble concept to the permit program, the question before it was not whether in its view the concept is “inappropriate” in the general context of a program designed to improve air quality, but whether the Administrator’s view that it is appropriate in the context of this particular program is a reasonable one. Based on the examination of the legislation and its history which follows, we agree with the Court of Appeals that Congress did not have a specific intention on the applicability of the bubble concept in these cases, and conclude that the EPA’s use of that concept here is a reasonable policy choice for the agency to make.

Ill

In the 1950’s and the 1960’s Congress enacted a series of statutes designed to encourage and to assist the States in curtailing air pollution. See generally Train v. Natural Resources Defense Council, Inc., 421 U. S. 60, 63-64 (1975). The Clean Air Amendments of 1970, Pub. L. 91-604, 84 Stat. 1676, “sharply increased federal authority and responsibility *846in the continuing effort to combat air pollution,” 421 U. S., at 64, but continued to assign “primary responsibility for assuring air quality” to the several States, 84 Stat. 1678. Section 109 of the 1970 Amendments directed the EPA to promulgate National Ambient Air Quality Standards (NAAQS’s)15 and § 110 directed the States to develop plans (SIP’s) to implement the standards within specified deadlines. In addition, § 111 provided that major new sources of pollution would be required to conform to technology-based, performance standards; the EPA was directed to publish a list of categories of sources of pollution and to establish new source performance standards (NSPS) for each. Section 111(e) prohibited the operation of any new source in violation of a performance standard.

Section 111(a) defined the terms that are to be used in setting and enforcing standards of performance for new stationary sources. It provided:

“For purposes of this section:
“(3) The term ‘stationary source’ means any building, structure, facility, or installation which emits or may emit any air pollutant.” 84 Stat. 1683.

In the 1970 Amendments that definition was not only applicable to the NSPS program required by § 111, but also was made applicable to a requirement of § 110 that each state implementation plan contain a procedure for reviewing the location of any proposed new source and preventing its construction if it would preclude the attainment or maintenance of national air quality standards.16

In due course, the EPA promulgated NAAQS’s, approved SIP’s, and adopted detailed regulations governing NSPS’s *847for various categories of equipment. In one of its programs, the EPA used a plantwide definition of the term “stationary source.” In 1974, it issued NSPS’s for the nonferrous smelting industry that provided that the standards would not apply to the modification of major smelting units if their increased emissions were offset by reductions in other portions of the same plant.17

Nonattainment

The 1970 legislation provided for the attainment of primary NAAQS’s by 1975. In many areas of the country, particularly the most industrialized States, the statutory goals were not attained.18 In 1976, the 94th Congress was confronted with this fundamental problem, as well as many others respecting pollution control. As always in this area, the legislative struggle was basically between interests seeking strict schemes to reduce pollution rapidly to eliminate its social costs and interests advancing the economic concern that strict schemes would retard industrial development with attendant social costs. The 94th Congress, confronting these competing interests, was unable to agree on what response was in the public interest: legislative proposals to deal with nonattainment failed to command the necessary consensus.19

In light of this situation, the EPA published an Emissions Offset Interpretative Ruling in December 1976, see 41 Fed. Reg. 55524, to “fill the gap,” as respondents put it, until Congress acted. The Ruling stated that it was intended to *848address “the issue of whether and to what extent national air quality standards established under the Clean Air Act may restrict or prohibit growth of major new or expanded stationary air pollution sources.” Id., at 55524-55525. In general, the Ruling provided that “a major new source may locate in an area with air quality worse than a national standard only if stringent conditions can be met.” Id., at 55525. The Ruling gave primary emphasis to the rapid attainment of the statute’s environmental goals.20 Consistent with that emphasis, the construction of every new source in nonattainment areas had to meet the “lowest achievable emission rate” under the current state of the art for that type of facility. See Ibid. The 1976 Ruling did not, however, explicitly adopt or reject the “bubble concept.”21

IV

The Clean Air Act Amendments of 1977 are a lengthy, detailed, technical, complex, and comprehensive response to a major social issue. A small portion of the statute — 91 Stat. *849745-751 (Part D of Title I of the amended Act, 42 U. S. C. §§7501-7508) — expressly deals with nonattainment areas. The focal point of this controversy is one phrase in that portion of the Amendments.22

Basically, the statute required each State in a non-attainment area to prepare and obtain approval of a new SIP by July 1, 1979. In the interim those States were required to comply with the EPA’s interpretative Ruling of December 21, 1976. 91 Stat. 745. The deadline for attainment of the primary NAAQS’s was extended until December 31, 1982, and in some cases until December 31, 1987, but the SIP’s were required to contain a number of provisions designed to achieve the goals as expeditiously as possible.23

*850Most significantly for our purposes, the statute provided that each plan shall

“(6) require permits for the construction and operation of new or modified major stationary sources in accordance with section 173 . . . Id., at 747.

Before issuing a permit, § 173 requires (1) the state agency to determine that there will be sufficient emissions reductions in the region to offset the emissions from the new source and also to allow for reasonable further progress toward attainment, or that the increased emissions will not exceed an allowance for growth established pursuant to § 172(b)(5); (2) the applicant to certify that his other sources in the State are in compliance with the SIP, (3) the agency to determine that the applicable SIP is otherwise being implemented, and (4) the proposed source to comply with the lowest achievable emission rate (LAER).24

*851The 1977 Amendments contain no specific reference to the “bubble concept.” Nor do they contain a specific definition of the term “stationary source,” though they did not disturb the definition of “stationary source” contained in § 111(a)(3), applicable by the terms of the Act to the NSPS program. Section 302(j), however, defines the term “major stationary source” as follows:

“(j) Except as otherwise expressly provided, the terms ‘major stationary source’ and ‘major emitting facility’ mean any stationary facility or source of air pollutants which directly emits, or has the potential to emit, one hundred tons per year or more of any air pollutant (including any major emitting facility or source of fugitive emissions of any such pollutant, as determined by rule by the Administrator).” 91 Stat. 770.

V

The legislative history of the portion of the 1977 Amendments dealing with nonattainment areas does not contain any specific comment on the “bubble concept” or the question whether a plantwide definition of a stationary source is permissible under the permit program. It does, however, plainly disclose that in the permit program Congress sought to accommodate the conflict between the economic interest in permitting capital improvements to continue and the environmental interest in improving air quality. Indeed, the House Committee Report identified the economic interest as one of the “two main purposes” of this section of the bill. It stated:

“Section 117 of the bill, adopted during full committee markup establishes a new section 127 of the Clean Air Act. The section has two main purposes: (1) to allow reasonable economic growth to continue in an area while making reasonable further progress to assure attainment of the standards by a fixed date; and (2) to allow *852States greater flexibility for the former purpose than EPA’s present interpretative regulations afford.
“The new provision allows States with nonattainment areas to pursue one of two options. First, the State may proceed under EPA’s present ‘tradeoff’ or ‘offset’ ruling. The Administrator is authorized, moreover, to modify or amend that ruling in accordance with the intent and purposes of this section.
“The State’s second option would be to revise its implementation plan in accordance with this new provision.” H. R. Rep. No. 95-294, p. 211 (1977).25

The portion of the Senate Committee Report dealing with nonattainment areas states generally that it was intended to “supersede the EPA administrative approach,” and that expansion should be permitted if a State could “demonstrate that these facilities can be accommodated within its overall plan to provide for attainment of air quality standards.” S. Rep. No. 95-127, p. 55 (1977). The Senate Report notes the value of “case-by-case review of each new or modified major source of pollution that seeks to locate in a region exceeding an ambient standard,” explaining that such a review “requires matching reductions from existing sources against *853emissions expected from the new source in order to assure that introduction of the new source will not prevent attainment of the applicable standard by the statutory deadline.” Ibid. This description of a case-by-case approach to plant additions, which emphasizes the net consequences of the construction or modification of a new source, as well as its impact on the overall achievement of the national standards, was not, however, addressed to the precise issue raised by these cases.

Senator Mustíe made the following remarks:

“I should note that the test for determining whether a new or modified source is subject to the EPA interpretative regulation [the Offset Ruling] — and to the permit requirements of the revised implementation plans under the conference bill — is whether the source will emit a pollutant into an area which is exceeding a national ambient air quality standard for that pollutant — or precursor. Thus, a new source is still subject to such requirements as ‘lowest achievable emission rate’ even if it is constructed as a replacement for an older facility resulting in a net reduction from previous emission levels.
“A source — including an existing facility ordered to convert to coal — is subject to all the nonattainment requirements as a modified source if it makes any physical change which increases the amount of any air pollutant for which the standards in the area are exceeded.” 123 Cong. Rec. 26847 (1977).

I — I >

As previously noted, prior to the 1977 Amendments, the EPA had adhered to a plantwide definition of the term “source” under a NSPS program. After adoption of the 1977 Amendments, proposals for a plantwide definition were considered in at least three formal proceedings.

In January 1979, the EPA considered the question whether the same restriction on new construction in nonattainment areas that had been included in its December 1976 Ruling *854should be required in the revised SIP’s that were scheduled to go into effect in July 1979. After noting that the 1976 Ruling was ambiguous on the question “whether a plant with a number of different processes and emission.points would be considered a single source,” 44 Fed. Reg. 3276 (1979), the EPA, in effect, provided a bifurcated answer to that question. In those areas that did not have a revised SIP in effect by July 1979, the EPA rejected the plantwide definition; on the other hand, it expressly concluded that the plantwide approach would be permissible in certain circumstances if authorized by an approved SIP. It stated:

“Where a state implementation plan is revised and implemented to satisfy the requirements of Part D, including the reasonable further progress requirement, the plan requirements for major modifications may exempt modifications of existing facilities that are accompanied by intrasource offsets so that there is no net increase in emissions. The agency endorses such exemptions, which would provide greater flexibility to sources to effectively manage their air emissions at least cost.” Ibid.26

*855In April, and again in September 1979', the EPA published additional comments in which it indicated that revised SIP’s could adopt the plantwide definition of source in non-attainment areas in certain circumstances. See id., at 20372, 20379, 51924, 51951, 51958. On the latter occasion, the EPA made a formal rulemaking proposal that would have permitted the use of the “bubble concept” for new installations within a plant as well as for modifications of existing units. It explained:

“‘Bubble’ Exemption: The use of offsets inside the same source is called the ‘bubble.’ EPA proposes use of the definition of ‘source’ (see above) to limit the use of the bubble under nonattainment requirements in the following respects:
“i. Part D SIPs that include all requirements needed to assure reasonable further progress and attainment by the deadline under section 172 and that are being carried out need not restrict the use of a plantwide bubble, the same as under the PSD proposal.
“ii. Part D SIPs that do not meet the requirements specified must limit use of the bubble by including a definition of ‘installation’ as an identifiable piece of process equipment.”27

*856Significantly, the EPA expressly noted that the word “source” might be given a plantwide definition for some purposes and a narrower definition for other purposes. It wrote:

“Source means any building structure, facility, or installation which emits or may emit any regulated pollutant. ‘Building, structure, facility or installation’ means plant in PSD areas and in nonattainment areas except where the growth prohibitions would apply or where no adequate SIP exists or is being carried out.” Id., at 51925.28

The EPA’s summary of its proposed Ruling discloses a flexible rather than rigid definition of the term “source” to implement various policies and programs:

“In summary, EPA is proposing two different ways to define source for different kinds of NSR programs:
“(1) For PSD and complete Part D SIPs, review would apply only to plants, with an unrestricted plant-wide bubble.
“(2) For the offset ruling, restrictions on construction, and incomplete Part D SIPs, review would apply to both plants and individual pieces of process equipment, causing the plant-wide bubble not to apply for new and modified major pieces of equipment.
“In addition, for the restrictions on construction, EPA is proposing to define ‘major modification’ so as to prohibit the bubble entirely. Finally, an alternative discussed but not favored is to have only pieces of process equipment reviewed, resulting in no plant-wide bubble and allowing minor pieces of equipment to escape NSR *857regardless of whether they are within a major plant.” Id., at 51934.

In August 1980, however, the EPA adopted a regulation that, in essence, applied the basic reasoning of the Court of Appeals in these cases. The EPA took particular note of the two then-recent Court of Appeals decisions, which had created the bright-line rule that the “bubble concept” should be employed in a program designed to maintain air quality but not in one designed to enhance air quality. Relying heavily on those cases,29 EPA adopted a dual definition of “source” for nonattainment areas that required a permit whenever a change in either the entire plant, or one of its components, would result in a significant increase in emissions even if the increase was completely offset by reductions elsewhere in the plant. The EPA expressed the opinion that this interpretation was “more consistent with congressional intent” than the plantwide definition because it “would bring in more sources or modifications for review,” 45 Fed. Reg. 52697 (1980), but its primary legal analysis was predicated on the two Court of Appeals decisions.

In 1981 a new administration took office and initiated a “Government-wide reexamination of regulatory burdens and complexities.” 46 Fed. Reg. 16281. In the context of that *858review, the EPA reevaluated the various arguments that had been advanced in connection with the proper definition of the term “source” and concluded that the term should be given the same definition in both nonattainment areas and PSD areas.

In explaining its conclusion, the EPA first noted that the definitional issue was not squarely addressed in either the statute or its legislative history and therefore that the issue involved an agency “judgment as how to best carry out the Act.” Ibid. It then set forth several reasons for concluding that the plantwide definition was more appropriate. It pointed out that the dual definition “can act as a disincentive to new investment and modernization by discouraging modifications to existing facilities” and “can actually retard progress in air pollution control by discouraging replacement of older, dirtier processes or pieces of equipment with new, cleaner ones.” Ibid. Moreover, the new definition “would simplify EPA’s rules by using the same definition of ‘source’ for PSD, nonattainment new source review and the construction moratorium. This reduces confusion and inconsistency. ” Ibid. Finally, the agency explained that additional requirements that remained in place would accomplish the fundamental purposes of achieving attainment with NAAQS’s as expeditiously as possible.30 These conclusions were ex*859pressed in a proposed rulemaking in August 1981 that was formally promulgated in October. See id., at 50766.

VII

In this Court respondents expressly reject the basic rationale of the Court of Appeals’ decision. That court viewed the statutory definition of the term “source” as sufficiently flexible to cover either a plantwide definition, a narrower definition covering each unit within a plant, or a dual definition that could apply to both the entire “bubble” and its components. It interpreted the policies of the statute, however, to mandate the plantwide definition in programs designed to maintain clean air and to forbid it in programs designed to improve air quality. Respondents place a fundamentally different construction on the statute. They contend that the text of thé Act requires the EPA to use a dual definition — if either a component of a plant, or the plant as a whole, emits over 100 tons of pollutant, it is a major stationary source. They thus contend that the EPA rules adopted in 1980, insofar as they apply to the maintenance of the quality of clean air, as well as the 1981 rules which apply to nonattainment areas, violate the statute.31

Statutory Language

The definition of the term “stationary source” in § 111(a)(3) refers to “any building, structure, facility, or installation” which emits air pollution. See supra, at 846. This definition is applicable only to the NSPS program by the express terms of the statute; the text of the statute does not make this defi*860nition applicable to the permit program. Petitioners therefore maintain that there is no statutory language even relevant to ascertaining the meaning of stationary source in the permit program aside from §302(j), which defines the term “major stationary source.” See supra, at 851. We disagree with petitioners on this point.

The definition in §302(j) tells us what the word “major” means — a source must emit at least 100 tons of pollution to qualify — but it sheds virtually no light on the meaning of the term “stationary source.” It does equate a source with a facility — a “major emitting facility” and a “major stationary source” are synonymous under § 302(j). The ordinary meaning of the term “facility” is some collection of integrated elements which has been designed and constructed to achieve some purpose. Moreover, it is certainly no affront to common English usage to take a reference to a major facility or a major source to connote an entire plant as opposed to its constituent parts. Basically, however, the language of §302(j) simply does not compel any given interpretation of the term “source.”

Respondents recognize that, and hence point to § 111(a)(3). Although the definition in that section is not literally applicable to the permit program, it sheds as much light on the meaning of the word “source” as anything in the statute.32 As respondents point out, use of the words “building, structure, facility, or installation,” as the definition of source, could be read to impose the permit conditions on an individual building that is a part of a plant.33 A “word may have a character of its own not to be submerged by its association.” Russell Motor Car Co. v. United States, 261 U. S. 514, 519 *861(1923). On the other hand, the meaning of a word must be ascertained in the context of achieving particular objectives, and the words associated with it may indicate that the true meaning of the series is to convey a common idea. The language may reasonably be interpreted to impose the requirement on any discrete, but integrated, operation which pollutes. This gives meaning to all of the terms — a single building, not part of a larger operation, would be covered if it emits more than 100 tons of pollution, as would any facility, structure, or installation. Indeed, the language itself implies a “bubble concept” of sorts: each enumerated item would seem to be treated as if it were encased in a bubble. While respondents insist that each of these terms must be given a discrete meaning, they also argue that § 111(a)(3) defines “source” as that term is used in § 302(j). The latter section, however, equates a source with a facility, whereas the former defines “source” as a facility, among other items.

We are not persuaded that parsing of general terms in the text of the statute will reveal an actual intent of Congress.34 *862We know full well that this language is not dispositive; the terms are overlapping and the language is not precisely-directed to the question of the applicability of a given term in the context of a larger operation. To the extent any congressional “intent” can be discerned from this language, it would appear that the listing of overlapping, illustrative terms was intended to enlarge, rather than to confine, the scope of the agency’s power to regulate particular sources in order to effectuate the policies of the Act.

Legislative History

In addition, respondents argue that the legislative history and policies of the Act foreclose the plantwide definition, and that the EPA’s interpretation is not entitled to deference because it represents a sharp break with prior interpretations of the Act.

Based on our examination of the legislative history, we agree with the Court of Appeals that it is unilluminating. The general remarks pointed to by respondents “were obviously not made with this narrow issue in mind and they cannot be said to demonstrate a Congressional desire . . . .” Jewell Ridge Coal Corp. v. Mine Workers, 325 U. S. 161, 168-169 (1945). Respondents’ argument based on the legislative history relies heavily on Senator Muskie’s observation that a new source is subject to the LAER requirement.35 But the full statement is ambiguous and like the text of § 173 itself, this comment does not tell us what a new source is, much less that it is to have an inflexible definition. We find that the legislative history as a whole is silent on the precise issue before us. It is, however, consistent with the view that the EPA should have broad discretion in implementing the policies of the 1977 Amendments.

*863More importantly, that history plainly identifies the policy concerns that motivated the enactment; the plantwide definition is fully consistent with one of those concerns — the allowance of reasonable economic growth — and, whether or not we believe it most effectively implements the other, we must recognize that the EPA has advanced a reasonable explanation for its conclusion that the regulations serve the environmental objectives as well. See supra, at 857-859, and n. 29; see also supra, at 855, n. 27. Indeed, its reasoning is supported by the public record developed in the rulemaking process,36 as well as by certain private studies.37

Our review of the EPA’s varying interpretations of the word “source” — both before and after the 1977 Amendments — convinces us that the agency primarily responsible for administering this important legislation has consistently interpreted it flexibly — not in a sterile textual vacuum, but in the context of implementing policy decisions in a technical and complex arena. The fact that the agency has from time to time changed its interpretation of the term “source” does not, as respondents argue, lead us to conclude that no deference should be accorded the agency’s interpretation of the statute. An initial agency interpretation is not instantly carved in stone. On the contrary, the agency, to engage in informed rulemaking, must consider varying interpretations *864and the wisdom of its policy on a continuing basis. Moreover, the fact that the agency has adopted different definitions in different contexts adds force to the argument that the definition itself is flexible, particularly since Congress has never indicated any disapproval of a flexible reading of the statute.

Significantly, it was not the agency in 1980, but rather the Court of Appeals that read the statute inflexibly to command a plantwide definition for programs designed to maintain clean air and to forbid such a definition for programs designed to improve air quality. The distinction the court drew may well be a sensible one, but our labored review of the problem has surely disclosed that it is not a distinction that Congress ever articulated itself, or one that the EPA found in the statute before the courts began to review the legislative work product. We conclude that it was the Court of Appeals, rather than Congress or any of the decision-makers who are authorized by Congress to administer this legislation, that was primarily responsible for the 1980 position taken by the agency.

Policy

The arguments over policy that are advanced in the parties’ briefs create the impression that respondents are now waging in a judicial forum a specific policy battle which they ultimately lost in the agency and in the 32 jurisdictions opting for the “bubble concept,” but one which was never waged in the Congress. Such policy arguments are more properly addressed to legislators or administrators, not to judges.38

*865In these cases the Administrator’s interpretation represents a reasonable accommodation of manifestly competing interests and is entitled to deference: the regulatory scheme is technical and complex,39 the agency considered the matter in a detailed and reasoned fashion,40 and the decision involves reconciling conflicting policies.41 Congress intended to accommodate both interests, but did not do so itself on the level of specificity presented by these cases. Perhaps that body consciously desired the Administrator to strike the balance at this level, thinking that those with great expertise and charged with responsibility for administering the provision would be in a better position to do so; perhaps it simply did not consider the question at this level; and perhaps Congress was unable to forge a coalition on either side of the question, and those on each side decided to take their chances with the scheme devised by the agency. For judicial purposes, it matters not which of these things occurred.

Judges are not experts in the field, and are not part of either political branch of the Government. Courts must, in some cases, reconcile competing political interests, but not on the basis of the judges’ personal policy preferences. In contrast, an agency to which Congress has delegated policymak-ing responsibilities may, within the limits of that delegation, properly rely upon the incumbent administration’s views of wise policy to inform its judgments. While agencies are not directly accountable to the people, the Chief Executive is, and it is entirely appropriate for this political branch of the Government to make such policy choices — resolving the competing interests which Congress itself either inadvertently did not resolve, or intentionally left to be resolved by the *866agency charged with the administration of the statute in light of everyday realities.

When a challenge to an agency construction of a statutory provision, fairly conceptualized, really centers on the wisdom of the agency’s policy, rather than whether it is a reasonable choice within a gap left open by Congress, the challenge must fail. In such a case, federal judges — who have no constituency — have a duty to respect legitimate policy choices made by those who do. The responsibilities for assessing the wisdom of such policy choices and resolving the struggle between competing views of the public interest are not judicial ones: “Our Constitution vests such responsibilities in the political branches.” TVA v. Hill, 437 U. S. 153, 195 (1978).

We hold that the EPA’s definition of the term “source” is a permissible construction of the statute which seeks to accommodate progress in reducing air pollution with economic growth. “The Regulations which the Adminstrator has adopted provide what the agency could allowably view as . .. [an] effective reconciliation of these twofold ends .. . .” United States v. Shimer, 367 U. S., at 383.

The judgment of the Court of Appeals is reversed.

It is so ordered.

[125] Justice O'Connor, delivered the opinion of the Court.

This case involves one of the most troubling public health problems facing our Nation today: the thousands of premature deaths that occur each year because of tobacco use. In 1996, the Food and Drug Administration (FDA), after having expressly disavowed any such authority since its inception, asserted jurisdiction to regulate tobacco products. See 61 Fed. Reg. 44619-45318. The FDA concluded that nicotine is a "drug" within the meaning of the Food, Drug, and Cosmetic Act (FDCA or Act), 52 Stat. 1040, as amended, 21 U. S. C. § 301 et seq., and that cigarettes and smokeless tobacco are "combination products" that deliver nicotine to the body. 61 Fed. Reg. 44397 (1996). Pursuant to this authority, it promulgated regulations intended to reduce tobacco consumption among children and adolescents. Id., at 44615-44618. The agency believed that, because most tobacco consumers begin their use before reaching the age of 18, curbing tobacco use by minors could substantially reduce the prevalence of addiction in future generations and thus the incidence of tobacco-related death and disease. Id., at 44398-44399.

Regardless of how serious the problem an administrative agency seeks to address, however, it may not exercise its authority "in a manner that is inconsistent with the administrative structure that Congress enacted into law." ETSI Pipeline Project v. Missouri, 484 U. S. 495, 517 (1988). And although agencies are generally entitled to deference in the interpretation of statutes that they administer, a reviewing "court, as well as the agency, must give effect to the unambiguously [126] expressed intent of Congress." Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837, 842-843 (1984). In this case, we believe that Congress has clearly precluded the FDA from asserting jurisdiction to regulate tobacco products. Such authority is inconsistent with the intent that Congress has expressed in the FDCA's overall regulatory scheme and in the tobacco-specific legislation that it has enacted subsequent to the FDCA. In light of this clear intent, the FDA's assertion of jurisdiction is impermissible.

The FDCA grants the FDA, as the designee of the Secretary of Health and Human Services (HHS), the authority to regulate, among other items, "drugs" and "devices." See 21 U. S. C. §§ 321(g)—(h), 393 (1994 ed. and Supp. III). The Act defines "drug" to include "articles (other than food) intended to affect the structure or any function of the body." 21 U. S. C. § 321(g)(1)(C). It defines "device," in part, as "an instrument, apparatus, implement, machine, contrivance, . . . or other similar or related article, including any component, part, or accessory, which is . . . intended to affect the structure or any function of the body." § 321(h). The Act also grants the FDA the authority to regulate so-called "combination products," which "constitute a combination of a drug, device, or biological product." § 353(g)(1). The FDA has construed this provision as giving it the discretion to regulate combination products as drugs, as devices, or as both. See 61 Fed. Reg. 44400 (1996).

On August 11, 1995, the FDA published a proposed rule concerning the sale of cigarettes and smokeless tobacco to children and adolescents. 60 Fed. Reg. 41314-41787. The rule, which included several restrictions on the sale, distribution, and advertisement of tobacco products, was designed to reduce the availability and attractiveness of tobacco products to young people. Id., at 41314. A public comment period followed, during which the FDA received over 700,000 submissions, [127] more than "at any other time in its history on any other subject." 61 Fed. Reg. 44418 (1996).

On August 28, 1996, the FDA issued a final rule entitled "Regulations Restricting the Sale and Distribution of Cigarettes and Smokeless Tobacco to Protect Children and Adolescents." Id., at 44396. The FDA determined that nicotine is a "drug" and that cigarettes and smokeless tobacco are "drug delivery devices," and therefore it had jurisdiction under the FDCA to regulate tobacco products as customarily marketed—that is, without manufacturer claims of therapeutic benefit. Id., at 44397, 44402. First, the FDA found that tobacco products "`affect the structure or any function of the body' " because nicotine "has significant pharmacological effects." Id., at 44631. Specifically, nicotine "exerts psychoactive, or mood-altering, effects on the brain" that cause and sustain addiction, have both tranquilizing and stimulating effects, and control weight. Id., at 44631-44632. Second, the FDA determined that these effects were "intended" under the FDCA because they "are so widely known and foreseeable that [they] may be deemed to have been intended by the manufacturers," id., at 44687; consumers use tobacco products "predominantly or nearly exclusively" to obtain these effects, id., at 44807; and the statements, research, and actions of manufacturers revealed that they "have `designed' cigarettes to provide pharmacologically active doses of nicotine to consumers," id., at 44849. Finally, the agency concluded that cigarettes and smokeless tobacco are "combination products" because, in addition to containing nicotine, they include device components that deliver a controlled amount of nicotine to the body, id., at 45208-45216.

Having resolved the jurisdictional question, the FDA next explained the policy justifications for its regulations, detailing the deleterious health effects associated with tobacco use. It found that tobacco consumption was "the single leading cause of preventable death in the United States." Id., at 44398. According to the FDA, "[m]ore than 400,000 [128] people die each year from tobacco-related illnesses, such as cancer, respiratory illnesses, and heart disease." Ibid. The agency also determined that the only way to reduce the amount of tobacco-related illness and mortality was to reduce the level of addiction, a goal that could be accomplished only by preventing children and adolescents from starting to use tobacco. Id., at 44398-44399. The FDA found that 82% of adult smokers had their first cigarette before the age of 18, and more than half had already become regular smokers by that age. Id., at 44398. It also found that children were beginning to smoke at a younger age, that the prevalence of youth smoking had recently increased, and that similar problems existed with respect to smokeless tobacco. Id., at 44398-44399. The FDA accordingly concluded that if "the number of children and adolescents who begin tobacco use can be substantially diminished, tobacco-related illness can be correspondingly reduced because data suggest that anyone who does not begin smoking in childhood or adolescence is unlikely ever to begin." Id., at 44399.

Based on these findings, the FDA promulgated regulations concerning tobacco products' promotion, labeling, and accessibility to children and adolescents. See id., at 44615-44618. The access regulations prohibit the sale of cigarettes or smokeless tobacco to persons younger than 18; require retailers to verify through photo identification the age of all purchasers younger than 27; prohibit the sale of cigarettes in quantities smaller than 20; prohibit the distribution of free samples; and prohibit sales through self-service displays and vending machines except in adult-only locations. Id., at 44616-44617. The promotion regulations require that any print advertising appear in a black-and-white, text-only format unless the publication in which it appears is read almost exclusively by adults; prohibit outdoor advertising within 1,000 feet of any public playground or school; prohibit the distribution of any promotional items, such as T-shirts or hats, bearing the manufacturer's brand name; and prohibit a [129] manufacturer from sponsoring any athletic, musical, artistic, or other social or cultural event using its brand name. Id., at 44617-44618. The labeling regulation requires that the statement, "A Nicotine-Delivery Device for Persons 18 or Older," appear on all tobacco product packages. Id., at 44617.

The FDA promulgated these regulations pursuant to its authority to regulate "restricted devices." See 21 U. S. C. § 360j(e). The FDA construed § 353(g)(1) as giving it the discretion to regulate "combination products" using the Act's drug authorities, device authorities, or both, depending on "how the public health goals of the act can be best accomplished." 61 Fed. Reg. 44403 (1996). Given the greater flexibility in the FDCA for the regulation of devices, the FDA determined that "the device authorities provide the most appropriate basis for regulating cigarettes and smokeless tobacco." Id., at 44404. Under 21 U. S. C. § 360j(e), the agency may "require that a device be restricted to sale, distribution, or use . . . upon such other conditions as [the FDA] may prescribe in such regulation, if, because of its potentiality for harmful effect or the collateral measures necessary to its use, [the FDA] determines that there cannot otherwise be reasonable assurance of its safety and effectiveness." The FDA reasoned that its regulations fell within the authority granted by § 360j(e) because they related to the sale or distribution of tobacco products and were necessary for providing a reasonable assurance of safety. 61 Fed. Reg. 44405-44407 (1996).

Respondents, a group of tobacco manufacturers, retailers, and advertisers, filed suit in United States District Court for the Middle District of North Carolina challenging the regulations. See Coyne Beahm, Inc. v. FDA, 966 F. Supp. 1374 (1997). They moved for summary judgment on the grounds that the FDA lacked jurisdiction to regulate tobacco products as customarily marketed, the regulations exceeded the FDA's authority under 21 U. S. C. § 360j(e), and the advertising [130] restrictions violated the First Amendment. Second Brief in Support of Plaintiffs' Motion for Summary Judgment in No. 2:95CV00591 (MDNC), in 3 Rec. in No. 97-1604 (CA4), Tab No. 40; Third Brief in Support of Plaintiffs' Motion for Summary Judgment in No. 2:95CV00591 (MDNC), in 3 Rec. in No. 97-1604 (CA4), Tab No. 42. The District Court granted respondents' motion in part and denied it in part. 966 F. Supp., at 1400. The court held that the FDCA authorizes the FDA to regulate tobacco products as customarily marketed and that the FDA's access and labeling regulations are permissible, but it also found that the agency's advertising and promotion restrictions exceed its authority under § 360j(e). Id., at 1380-1400. The court stayed implementation of the regulations it found valid (except the prohibition on the sale of tobacco products to minors) and certified its order for immediate interlocutory appeal. Id., at 1400-1401.

The Court of Appeals for the Fourth Circuit reversed, holding that Congress has not granted the FDA jurisdiction to regulate tobacco products. See 153 F. 3d 155 (1998). Examining the FDCA as a whole, the court concluded that the FDA's regulation of tobacco products would create a number of internal inconsistencies. Id., at 162-167. Various provisions of the Act require the agency to determine that any regulated product is "safe" before it can be sold or allowed to remain on the market, yet the FDA found in its rulemaking proceeding that tobacco products are "dangerous" and "unsafe." Id., at 164-167. Thus, the FDA would apparently have to ban tobacco products, a result the court found clearly contrary to congressional intent. Ibid. This apparent anomaly, the Court of Appeals concluded, demonstrates that Congress did not intend to give the FDA authority to regulate tobacco. Id., at 167. The court also found that evidence external to the FDCA confirms this conclusion. Importantly, the FDA consistently stated before 1995 that it lacked jurisdiction over tobacco, and Congress has enacted [131] several tobacco-specific statutes fully cognizant of the FDA's position. See id., at 168-176. In fact, the court reasoned, Congress has considered and rejected many bills that would have given the agency such authority. See id., at 170-171. This, along with the absence of any intent by the enacting Congress in 1938 to subject tobacco products to regulation under the FDCA, demonstrates that Congress intended to withhold such authority from the FDA. Id., at 167-176. Having resolved the jurisdictional question against the agency, the Court of Appeals did not address whether the regulations exceed the FDA's authority under 21 U. S. C. § 360j(e) or violate the First Amendment. See 153 F. 3d, at 176, n. 29.

We granted the federal parties' petition for certiorari, 526 U. S. 1086 (1999), to determine whether the FDA has authority under the FDCA to regulate tobacco products as customarily marketed.

II

The FDA's assertion of jurisdiction to regulate tobacco products is founded on its conclusions that nicotine is a "drug" and that cigarettes and smokeless tobacco are "drug delivery devices." Again, the FDA found that tobacco products are "intended" to deliver the pharmacological effects of satisfying addiction, stimulation and tranquilization, and weight control because those effects are foreseeable to any reasonable manufacturer, consumers use tobacco products to obtain those effects, and tobacco manufacturers have designed their products to produce those effects. 61 Fed. Reg. 44632-44633 (1996). As an initial matter, respondents take issue with the FDA's reading of "intended," arguing that it is a term of art that refers exclusively to claims made by the manufacturer or vendor about the product. See Brief for Respondent Brown & Williamson Tobacco Corp. 6. That is, a product is not a drug or device under the FDCA unless the manufacturer or vendor makes some express claim concerning the product's therapeutic benefits. See id., at 6-7. We [132] need not resolve this question, however, because assuming, arguendo, that a product can be "intended to affect the structure or any function of the body" absent claims of therapeutic or medical benefit, the FDA's claim to jurisdiction contravenes the clear intent of Congress.

A threshold issue is the appropriate framework for analyzing the FDA's assertion of authority to regulate tobacco products. Because this case involves an administrative agency's construction of a statute that it administers, our analysis is governed by Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837 (1984). Under Chevron, a reviewing court must first ask "whether Congress has directly spoken to the precise question at issue." Id., at 842. IfCongress has done so, the inquiry is at an end; the court "must give effect to the unambiguously expressed intent of Congress." Id., at 843; see also United States v. Haggar Apparel Co., 526 U. S. 380, 392 (1999); Holly Farms Corp. v. NLRB, 517 U. S. 392, 398 (1996). But if Congress has not specifically addressed the question, a reviewing court must respect the agency's construction of the statute so long as it is permissible. See INS v. Aguirre-Aguirre, 526 U. S. 415, 424 (1999); Auer v. Robbins, 519 U. S. 452, 457 (1997). Such deference is justified because "[t]he responsibilities for assessing the wisdom of such policy choices and resolving the struggle between competing views of the public interest are not judicial ones," Chevron, supra, at 866, and because of the agency's greater familiarity with the everchanging facts and circumstances surrounding the subjects regulated, see Rust v. Sullivan, 500 U. S. 173, 187 (1991).

In determining whether Congress has specifically addressed the question at issue, a reviewing court should not confine itself to examining a particular statutory provision in isolation. The meaning—or ambiguity—of certain words or phrases may only become evident when placed in context. See Brown v. Gardner, 513 U. S. 115, 118 (1994) ("Ambiguity is a creature not of definitional possibilities but of statutory [133] context"). It is a "fundamental canon of statutory construction that the words of a statute must be read in their context and with a view to their place in the overall statutory scheme." Davis v. Michigan Dept. of Treasury, 489 U. S. 803, 809 (1989). A court must therefore interpret the statute "as a symmetrical and coherent regulatory scheme," Gustafson v. Alloyd Co., 513 U. S. 561, 569 (1995), and "fit, if possible, all parts into an harmonious whole," FTC v. Mandel Brothers, Inc., 359 U. S. 385, 389 (1959). Similarly, the meaning of one statute may be affected by other Acts, particularly where Congress has spoken subsequently and more specifically to the topic at hand. See United States v. Estate of Romani, 523 U. S. 517, 530-531 (1998); United States v. Fausto, 484 U. S. 439, 453 (1988). In addition, we must be guided to a degree by common sense as to the manner in which Congress is likely to delegate a policy decision of such economic and political magnitude to an administrative agency. Cf. MCI Telecommunications Corp. v. American Telephone & Telegraph Co., 512 U. S. 218, 231 (1994).

With these principles in mind, we find that Congress has directly spoken to the issue here and precluded the FDA's jurisdiction to regulate tobacco products.

A

Viewing the FDCA as a whole, it is evident that one of the Act's core objectives is to ensure that any product regulated by the FDA is "safe" and "effective" for its intended use. See 21 U. S. C. § 393(b)(2) (1994 ed., Supp. III) (defining the FDA's mission); More Information for Better Patient Care: Hearing before the Senate Committee on Labor and Human Resources, 104th Cong., 2d Sess., 83 (1996) (statement of FDA Deputy Comm'r Schultz) ("A fundamental precept of drug and device regulation in this country is that these products must be proven safe and effective before they can be sold"). This essential purpose pervades the FDCA. For instance, 21 U. S. C. § 393(b)(2) (1994 ed., Supp. III) defines [134] the FDA's "[m]ission" to include "protect[ing] the public health by ensuring that . . . drugsare safe and effective" and that "there is reasonable assurance of the safety and effectiveness of devices intended for human use." The FDCA requires premarket approval of any new drug, with some limited exceptions, and states that the FDA "shall issue an order refusing to approve the application" of a new drug if it is not safe and effective for its intended purpose. §§ 355(d)(1)-(2), (4)-(5). If the FDA discovers after approval that a drug is unsafe or ineffective, it "shall, after due notice and opportunity for hearing to the applicant, withdraw approval" of the drug. 21 U. S. C. §§ 355(e)(1)-(3). The Act also requires the FDA to classify all devices into one of three categories. § 360c(b)(1). Regardless of which category the FDA chooses, there must be a "reasonable assurance of the safety and effectiveness of the device." 21 U. S. C. §§ 360c(a)(1)(A)(i), (B), (C) (1994 ed. and Supp. III); 61 Fed. Reg. 44412 (1996). Even the "restricted device" provision pursuant to which the FDA promulgated the regulations at issue here authorizes the agency to place conditions on the sale or distribution of a device specifically when "there cannot otherwise be reasonable assurance of its safety and effectiveness." 21 U. S. C. § 360j(e). Thus, the Act generally requires the FDA to prevent the marketing of any drug or device where the "potential for inflicting death or physical injury is not offset by the possibility of therapeutic benefit." United States v. Rutherford, 442 U. S. 544, 556 (1979).

In its rulemaking proceeding, the FDA quite exhaustively documented that "tobacco products are unsafe," "dangerous," and "cause great pain and suffering from illness." 61 Fed. Reg. 44412 (1996). It found that the consumption of tobacco products presents "extraordinary health risks," and that "tobacco use is the single leading cause of preventable death in the United States." Id., at 44398. It stated that "[m]ore than 400,000 people die each year from tobaccorelated illnesses, such as cancer, respiratory illnesses, and [135] heart disease, often suffering long and painful deaths," and that "[t]obacco alone kills more people each year in the United States than acquired immunodeficiency syndrome (AIDS), car accidents, alcohol, homicides, illegal drugs, suicides, and fires, combined." Ibid. Indeed, the FDA characterized smoking as "a pediatric disease," id., at 44421, because "one out of every three young people who become regular smokers . . . will die prematurely as a result," id., at 44399.

These findings logically imply that, if tobacco products were "devices" under the FDCA, the FDA would be required to remove them from the market. Consider, first, the FDCA's provisions concerning the misbranding of drugs or devices. The Act prohibits "[t]he introduction or delivery for introduction into interstate commerce of any food, drug, device, or cosmetic that is adulterated or misbranded." 21 U. S. C. § 331(a). In light of the FDA's findings, two distinct FDCA provisions would render cigarettes and smokeless tobacco misbranded devices. First, § 352(j) deems a drug or device misbranded "[i]f it is dangerous to health when used in the dosage or manner, or with the frequency or duration prescribed, recommended, or suggested in the labeling thereof." The FDA's findings make clear that tobacco products are "dangerous to health" when used in the manner prescribed. Second, a drug or device is misbranded under the Act "[u]nless its labeling bears . . . adequate directions for use . . . in such manner and form, as are necessary for the protection of users," except where such directions are "not necessary for the protection of the public health." § 352(f)(1). Given the FDA's conclusions concerning the health consequences of tobacco use, there are no directions that could adequately protect consumers. That is, there are no directions that could make tobacco products safe for obtaining their intended effects. Thus, were tobacco products within the FDA's jurisdiction, the Act would deem them misbranded devices that could not be introduced into interstate [136] commerce. Contrary to the dissent's contention, the Act admits no remedial discretion once it is evident that the device is misbranded.

Second, the FDCA requires the FDA to place all devices that it regulates into one of three classifications. See § 360c(b)(1). The agency relies on a device's classification in determining the degree of control and regulation necessary to ensure that there is "a reasonable assurance of safety and effectiveness." 61 Fed. Reg. 44412 (1996). The FDA has yet to classify tobacco products. Instead, the regulations at issue here represent so-called "general controls," which the Act entitles the agency to impose in advance of classification. See id., at 44404-44405. Although the FDCA prescribes no deadline for device classification, the FDA has stated that it will classify tobacco products "in a future rulemaking" as required by the Act. Id., at 44412. Given the FDA's findings regarding the health consequences of tobacco use, the agency would have to place cigarettes and smokeless tobacco in Class III because, even after the application of the Act's available controls, they would "presen[t] a potential unreasonable risk of illness or injury." 21 U. S. C. § 360c(a)(1)(C). As Class III devices, tobacco products would be subject to the FDCA's premarket approval process. See 21 U. S. C. § 360c(a)(1)(C) (1994 ed., Supp. III); 21 U. S. C. § 360e; 61 Fed. Reg. 44412 (1996). Under these provisions, the FDA would be prohibited from approving an application for premarket approval without "a showing of reasonable assurance that such device is safe under the conditions of use prescribed, recommended, or suggested in the proposed labeling thereof." 21 U. S. C. § 360e(d)(2)(A). In view of the FDA's conclusions regarding the health effects of tobacco use, the agency would have no basis for finding any such reasonable assurance of safety. Thus, once the FDA fulfilled its statutory obligation to classify tobacco products, it could not allow them to be marketed.

[137] The FDCA's misbranding and device classification provisions therefore make evident that were the FDA to regulate cigarettes and smokeless tobacco, the Act would require the agency to ban them. In fact, based on these provisions, the FDA itself has previously taken the position that if tobacco products were within its jurisdiction, "they would have to be removed from the market because it would be impossible to prove they were safe for their intended us[e]." Public Health Cigarette Amendments of 1971: Hearings before the Commerce Subcommittee on S. 1454, 92d Cong., 2d Sess., 239 (1972) (hereinafter 1972 Hearings) (statement of FDA Comm'r Charles Edwards). See also Cigarette Labeling and Advertising: Hearings before the House Committee on Interstate and Foreign Commerce, 88th Cong., 2d Sess., 18 (1964) (hereinafter 1964 Hearings) (statement of Dept. of Health, Education, and Welfare (HEW) Secretary Anthony Celebrezze that proposed amendments to the FDCA that would have given the FDA jurisdiction over "smoking product[s]" "might well completely outlaw at least cigarettes").

Congress, however, has foreclosed the removal of tobacco products from the market. A provision of the United States Code currently in force states that "[t]he marketing of tobacco constitutes one of the greatest basic industries of the United States with ramifying activities which directly affect interstate and foreign commerce at every point, and stable conditions therein are necessary to the general welfare." 7 U. S. C. § 1311(a). More importantly, Congress has directly addressed the problem of tobacco and health through legislation on six occasions since 1965. See Federal Cigarette Labeling and Advertising Act (FCLAA), Pub. L. 89-92, 79 Stat. 282; Public Health Cigarette Smoking Act of 1969, Pub. L. 91-222, 84 Stat. 87; Alcohol and Drug Abuse Amendments of 1983, Pub. L. 98-24, 97 Stat. 175; Comprehensive Smoking Education Act, Pub. L. 98-474, 98 Stat. 2200; Comprehensive Smokeless Tobacco Health Education Act of 1986, Pub. L. 99-252, 100 Stat. 30; Alcohol, Drug Abuse, and Mental [138] Health Administration Reorganization Act, Pub. L. 102-321, § 202, 106 Stat. 394. When Congress enacted these statutes, the adverse health consequences of tobacco use were well known, as were nicotine's pharmacological effects. See, e. g., U. S. Dept. of Health, Education, and Welfare, U. S. Surgeon General's Advisory Committee, Smoking and Health 25-40, 69-75 (1964) (hereinafter 1964 Surgeon General's Report) (concluding that cigarette smoking causes lung cancer, coronary artery disease, and chronic bronchitis and emphysema, and that nicotine has various pharmacological effects, including stimulation, tranquilization, and appetite suppression); U. S. Dept. of Health and Human Services, Public Health Service, Health Consequences of Smoking for Women 7-12 (1980) (finding that mortality rates for lung cancer, chronic lung disease, and coronary heart disease are increased for both women and men smokers, and that smoking during pregnancy is associated with significant adverse health effects on the unborn fetus and newborn child); U. S. Dept. of Health and Human Services, Public Health Service, Why People Smoke Cigarettes (1983), in Smoking Prevention Education Act, Hearings on H. R. 1824 before the Subcommittee on Health and the Environment of the House Committee on Energy and Commerce, 98th Cong., 1st Sess., 32-37 (1983) (hereinafter 1983 House Hearings) (stating that smoking is "the most widespread example of drug dependence in our country," and that cigarettes "affect the chemistry of the brain and nervous system"); U. S. Dept. of Health and Human Services, Public Health Service, The Health Consequences of Smoking: Nicotine Addiction 6-9, 145-239 (1988) (hereinafter 1988 Surgeon General's Report) (concluding that tobacco products are addicting in much the same way as heroin and cocaine, and that nicotine is the drug that causes addiction). Nonetheless, Congress stopped well short of ordering a ban. Instead, it has generally regulated the labeling and advertisement of tobacco products, expressly providing that it is the policy of Congress that "commerce and the national [139] economy may be . . . protected to the maximum extent consistent with" consumers "be[ing] adequately informed about any adverse health effects." 15 U. S. C. § 1331. Congress' decisions to regulate labeling and advertising and to adopt the express policy of protecting "commerce and the national economy . . . to the maximum extent" reveal its intent that tobacco products remain on the market. Indeed, the collective premise of these statutes is that cigarettes and smokeless tobacco will continue to be sold in the United States. A ban of tobacco products by the FDA would therefore plainly contradict congressional policy.

The FDA apparently recognized this dilemma and concluded, somewhat ironically, that tobacco products are actually "safe" within the meaning of the FDCA. In promulgating its regulations, the agency conceded that "tobacco products are unsafe, as that term is conventionally understood." 61 Fed. Reg. 44412 (1996). Nonetheless, the FDA reasoned that, in determining whether a device is safe under the Act, it must consider "not only the risks presented by a product but also any of the countervailing effects of use of that product, including the consequences of not permitting the product to be marketed." Id., at 44412-44413. Applying this standard, the FDA found that, because of the high level of addiction among tobacco users, a ban would likely be "dangerous." Id., at 44413. In particular, current tobacco users could suffer from extreme withdrawal, the health care system and available pharmaceuticals might not be able to meet the treatment demands of those suffering from withdrawal, and a black market offering cigarettes even more dangerous than those currently sold legally would likely develop. Ibid. The FDA therefore concluded that, "while taking cigarettes and smokeless tobacco off the market could prevent some people from becoming addicted and reduce death and disease for others, the record does not establish that such a ban is the appropriate public health response under the act." Id., at 44398.

[140] It may well be, as the FDA asserts, that "these factors must be considered when developing a regulatory scheme that achieves the best public health result for these products." Id., at 44413. But the FDA's judgment that leaving tobacco products on the market "is more effective in achieving public health goals than a ban," ibid., is no substitute for the specific safety determinations required by the FDCA's various operative provisions. Several provisions in the Act require the FDA to determine that the product itself is safe as used by consumers. That is, the product's probable therapeutic benefits must outweigh its risk of harm. See United States v. Rutherford, 442 U. S., at 555 ("[T]he Commissioner generally considers a drug safe when the expected therapeutic gain justifies the risk entailed by its use"). In contrast, the FDA's conception of safety would allow the agency, with respect to each provision of the FDCA that requires the agency to determine a product's "safety" or "dangerousness," to compare the aggregate health effects of alternative administrative actions. This is a qualitatively different inquiry. Thus, although the FDA has concluded that a ban would be "dangerous," it has not concluded that tobacco products are "safe" as that term is used throughout the Act.

Consider 21 U. S. C. § 360c(a)(2), which specifies those factors that the FDA may consider in determining the safety and effectiveness of a device for purposes of classification, performance standards, and premarket approval. For all devices regulated by the FDA, there must at least be a "reasonable assurance of the safety and effectiveness of the device." See 21 U. S. C. §§ 360c(a)(1)(A)(i), (B), (C) (1994 ed. and Supp. III); 61 Fed. Reg. 44412 (1996). Title 21 U. S. C. § 360c(a)(2) provides that

"the safety and effectiveness of a device are to be determined—

"(A) with respect to the persons for whose use the device is represented or intended,

[141] "(B) with respect to the conditions of use prescribed, recommended, or suggested in the labeling of the device, and

"(C) weighing any probable benefit to health from the use of the device against any probable risk of injury or illness from such use."

A straightforward reading of this provision dictates that the FDA must weigh the probable therapeutic benefits of the device to the consumer against the probable risk of injury. Applied to tobacco products, the inquiry is whether their purported benefits—satisfying addiction, stimulation and sedation, and weight control—outweigh the risks to health from their use. To accommodate the FDA's conception of safety, however, one must read "any probable benefit to health" to include the benefit to public health stemming from adult consumers' continued use of tobacco products, even though the reduction of tobacco use is the raison d'être of the regulations. In other words, the FDA is forced to contend that the very evil it seeks to combat is a "benefit to health." This is implausible.

The FDA's conception of safety is also incompatible with the FDCA's misbranding provision. Again, § 352(j) provides that a product is "misbranded" if "it is dangerous to health when used in the dosage or manner, or with the frequency or duration prescribed, recommended, or suggested in the labeling thereof." According to the FDA's understanding, a product would be "dangerous to health," and therefore misbranded under § 352(j), when, in comparison to leaving the product on the market, a ban would not produce "adverse health consequences" in aggregate. Quite simply, these are different inquiries. Although banning a particular product might be detrimental to public health in aggregate, the product could still be "dangerous to health" when used as directed. Section 352(j) focuses on dangers to the consumer from use of the product, not those stemming from the agency's remedial measures.

[142] Consequently, the analogy made by the FDA and the dissent to highly toxic drugs used in the treatment of various cancers is unpersuasive. See 61 Fed. Reg. 44413 (1996); post, at 177 (opinion of Breyer, J.). Although "dangerous" in some sense, these drugs are safe within the meaning of the Act because, for certain patients, the therapeutic benefits outweigh the risk of harm. Accordingly, such drugs cannot properly be described as "dangerous to health" under 21 U. S. C. § 352(j). The same is not true for tobacco products. As the FDA has documented in great detail, cigarettes and smokeless tobacco are an unsafe means to obtaining any pharmacological effect.

The dissent contends that our conclusion means that "the FDCA requires the FDA to ban outright `dangerous' drugs or devices," post, at 174, and that this is a "perverse" reading of the statute, post, at 174, 180. This misunderstands our holding. The FDA, consistent with the FDCA, may clearly regulate many "dangerous" products without banning them. Indeed, virtually every drug or device poses dangers under certain conditions. What the FDA may not do is conclude that a drug or device cannot be used safely for any therapeutic purpose and yet, at the same time, allow that product to remain on the market. Such regulation is incompatible with the FDCA's core objective of ensuring that every drug or device is safe and effective.

Considering the FDCA as a whole, it is clear that Congress intended to exclude tobacco products from the FDA's jurisdiction. A fundamental precept of the FDCA is that any product regulated by the FDA—but not banned—must be safe for its intended use. Various provisions of the Act make clear that this refers to the safety of using the product to obtain its intended effects, not the public health ramifications of alternative administrative actions by the FDA. That is, the FDA must determine that there is a reasonable assurance that the product's therapeutic benefits outweigh the risk of harm to the consumer. According to this standard, [143] the FDA has concluded that, although tobacco products might be effective in delivering certain pharmacological effects, they are "unsafe" and "dangerous" when used for these purposes. Consequently, if tobacco products were within the FDA's jurisdiction, the Act would require the FDA to remove them from the market entirely. But a ban would contradict Congress' clear intent as expressed in its more recent, tobacco-specific legislation. The inescapable conclusion is that there is no room for tobacco products within the FDCA's regulatory scheme. If they cannot be used safely for any therapeutic purpose, and yet they cannot be banned, they simply do not fit.

B

In determining whether Congress has spoken directly to the FDA's authority to regulate tobacco, we must also consider in greater detail the tobacco-specific legislation that Congress has enacted over the past 35 years. At the time a statute is enacted, it may have a range of plausible meanings. Over time, however, subsequent acts can shape or focus those meanings. The "classic judicial task of reconciling many laws enacted over time, and getting them to `make sense' in combination, necessarily assumes that the implications of a statute may be altered by the implications of a later statute." United States v. Fausto, 484 U. S., at 453. This is particularly so where the scope of the earlier statute is broad but the subsequent statutes more specifically address the topic at hand. As we recognized recently in United States v. Estate of Romani, "a specific policy embodied in a later federal statute should control our construction of the [earlier] statute, even though it ha[s] not been expressly amended." 523 U. S., at 530-531.

Congress has enacted six separate pieces of legislation since 1965 addressing the problem of tobacco use and human health. See supra, at 137-138. Those statutes, among other things, require that health warnings appear on all packaging and in all print and outdoor advertisements, see [144] 15 U. S. C. §§ 1331, 1333, 4402; prohibit the advertisement of tobacco products through "any medium of electronic communication" subject to regulation by the Federal Communications Commission (FCC), see §§ 1335, 4402(f); require the Secretary of HHS to report every three years to Congress on research findings concerning "the addictive property of tobacco," 42 U. S. C. § 290aa—2(b)(2); and make States' receipt of certain federal block grants contingent on their making it unlawful "for any manufacturer, retailer, or distributor of tobacco products to sell or distribute any such product to any individual under the age of 18," § 300x—26(a)(1).

In adopting each statute, Congress has acted against the backdrop of the FDA's consistent and repeated statements that it lacked authority under the FDCA to regulate tobacco absent claims of therapeutic benefit by the manufacturer. In fact, on several occasions over this period, and after the health consequences of tobacco use and nicotine's pharmacological effects had become well known, Congress considered and rejected bills that would have granted the FDA such jurisdiction. Under these circumstances, it is evident that Congress' tobacco-specific statutes have effectively ratified the FDA's long-held position that it lacks jurisdiction under the FDCA to regulate tobacco products. Congress has created a distinct regulatory scheme to address the problem of tobacco and health, and that scheme, as presently constructed, precludes any role for the FDA.

On January 11, 1964, the Surgeon General released the report of the Advisory Committee on Smoking and Health. That report documented the deleterious health effects of smoking in great detail, concluding, in relevant part, "that cigarette smoking contributes substantially to mortality from certain specific diseases and to the overall death rate." 1964 Surgeon General's Report 31. It also identified the pharmacological effects of nicotine, including "stimulation," "tranquilization," and "suppression of appetite." Id., at 74-75. Seven days after the report's release, the Federal Trade [145] Commission (FTC) issued a notice of proposed rulemaking, see 29 Fed. Reg. 530-532 (1964), and in June 1964, the FTC promulgated a final rule requiring cigarette manufacturers "to disclose, clearly and prominently, in all advertising and on every pack, box, carton or other container . . . that cigarette smoking is dangerous to health and may cause death from cancer and other diseases," id., at 8325. The rule was to become effective January 1, 1965, but, on a request from Congress, the FTC postponed enforcement for six months. See Cipollone v. Liggett Group, Inc., 505 U. S. 504, 513-514 (1992).

In response to the Surgeon General's report and the FTC's proposed rule, Congress convened hearings to consider legislation addressing "the tobacco problem." 1964 Hearings 1. During those deliberations, FDA representatives testified before Congress that the agency lacked jurisdiction under the FDCA to regulate tobacco products. Surgeon General Terry was asked during hearings in 1964 whether HEW had the "authority to brand or label the packages of cigarettes or to control the advertising there." Id., at 56. The Surgeon General stated that "we do not have such authority in existing laws governing the . . . Food and Drug Administration." Ibid. Similarly, FDA Deputy Commissioner Rankin testified in 1965 that "[t]he Food and Drug Administration has no jurisdiction under the Food, Drug, and Cosmetic Act over tobacco, unless it bears drug claims." Cigarette Labeling and Advertising—1965: Hearings on H. R. 2248 before the House Committee on Interstate and Foreign Commerce, 89th Cong., 1st Sess., 193 (hereinafter 1965 Hearings). See also Letter to Directors of Bureaus, Divisions and Directors of Districts from FDA Bureau of Enforcement (May 24, 1963), in 1972 Hearings 240 ("[T]obacco marketed for chewing or smoking without accompanying therapeutic claims, does not meet the definitions in the Food, Drug, and Cosmetic Act for food, drug, device or cosmetic"). In fact, HEW Secretary Celebrezze urged Congress not to amend the FDCA to cover [146] "smoking products" because, in light of the findings in the Surgeon General's report, such a "provision might well completely outlaw at least cigarettes. This would be contrary to what, we understand, is intended or what, in the light of our experience with the 18th amendment, would be acceptable to the American people." 1964 Hearings 18.

The FDA's disavowal of jurisdiction was consistent with the position that it had taken since the agency's inception. As the FDA concedes, it never asserted authority to regulate tobacco products as customarily marketed until it promulgated the regulations at issue here. See Brief for Petitioners 37; see also Brief for Appellee (FDA) in Action on Smoking and Health v. Harris, 655 F. 2d 236 (CADC 1980), in 9 Rec. in No. 97-1604 (CA4), Tab No. 4, pp. 14-15 ("In the 73 years since the enactment of the original Food and Drug Act, and in the 41 years since the promulgation of the modern Food, Drug, and Cosmetic Act, the FDA has repeatedly informed Congress that cigarettes are beyond the scope of the statute absent health claims establishing a therapeutic intent on behalf of the manufacturer or vendor").

The FDA's position was also consistent with Congress' specific intent when it enacted the FDCA. Before the Act's adoption in 1938, the FDA's predecessor agency, the Bureau of Chemistry, announced that it lacked authority to regulate tobacco products under the Pure Food and Drug Act of 1906, ch. 3915, 34 Stat. 768, unless they were marketed with therapeutic claims. See U. S. Dept. of Agriculture, Bureau of Chemistry, 13 Service and Regulatory Announcements 24 (Apr. 1914) (Feb. 1914 Announcements ¶ 13, Opinion of Chief of Bureau C. L. Alsberg). In 1929, Congress considered and rejected a bill "[t]o amend the Food and Drugs Act of June 30, 1906, by extending its provisions to tobacco and tobacco products." S. 1468, 71st Cong., 1st Sess., 1. See also 71 Cong. Rec. 2589 (1929) (remarks of Sen. Smoot). And, as the FDA admits, there is no evidence in the text of the FDCA or its legislative history that Congress in 1938 even considered [147] the applicability of the Act to tobacco products. See Brief for Petitioners 22, n. 4. Given the economic and political significance of the tobacco industry at the time, it is extremely unlikely that Congress could have intended to place tobacco within the ambit of the FDCA absent any discussion of the matter. Of course, whether the Congress that enacted the FDCA specifically intended the Act to cover tobacco products is not determinative; "it is ultimately the provisions of our laws rather than the principal concerns of our legislators by which we are governed." Oncale v. Sundowner Offshore Services, Inc., 523 U. S. 75, 79 (1998); see also TVA v. Hill, 437 U. S. 153, 185 (1978) ("It is not for us to speculate, much less act, on whether Congress would have altered its stance had the specific events of this case been anticipated"). Nonetheless, this intent is certainly relevant to understanding the basis for the FDA's representations to Congress and the background against which Congress enacted subsequent tobacco-specific legislation.

Moreover, before enacting the FCLAA in 1965, Congress considered and rejected several proposals to give the FDA the authority to regulate tobacco. In April 1963, Representative Udall introduced a bill "[t]o amend the Federal Food, Drug, and Cosmetic Act so as to make that Act applicable to smoking products." H. R. 5973, 88th Cong., 1st Sess., 1. Two months later, Senator Moss introduced an identical bill in the Senate. S. 1682, 88th Cong., 1st Sess. (1963). In discussing his proposal on the Senate floor, Senator Moss explained that "this amendment simply places smoking products under FDA jurisdiction, along with foods, drugs, and cosmetics." 109 Cong. Rec. 10322 (1963). In December 1963, Representative Rhodes introduced another bill that would have amended the FDCA "by striking out `food, drug, device, or cosmetic, each place where it appears therein and inserting in lieu thereof `food, drug, device, cosmetic, or smoking product.' " H. R. 9512, 88th Cong., 1st Sess., § 3 (1963). And in January 1965, five months before passage of [148] the FCLAA, Representative Udall again introduced a bill to amend the FDCA "to make that Act applicable to smoking products." H. R. 2248, 89th Cong., 1st Sess., 1. None of these proposals became law.

Congress ultimately decided in 1965 to subject tobacco products to the less extensive regulatory scheme of the FCLAA, which created a "comprehensive Federal program to deal with cigarette labeling and advertising with respect to any relationship between smoking and health." Pub. L. 89-92, § 2, 79 Stat. 282. The FCLAA rejected any regulation of advertising, but it required the warning, "Caution: Cigarette Smoking May Be Hazardous to Your Health," to appear on all cigarette packages. Id., § 4, 79 Stat. 283. In the FCLAA's "Declaration of Policy," Congress stated that its objective was to balance the goals of ensuring that "the public may be adequately informed that cigarette smoking may be hazardous to health" and protecting "commerce and the national economy . . . to the maximum extent." Id., § 2, 79 Stat. 282 (codified at 15 U. S. C. § 1331).

Not only did Congress reject the proposals to grant the FDA jurisdiction, but it explicitly pre-empted any other regulation of cigarette labeling: "No statement relating to smoking and health, other than the statement required by . . . this Act, shall be required on any cigarette package." Pub. L. 89-92, § 5(a), 79 Stat. 283. The regulation of product labeling, however, is an integral aspect of the FDCA, both as it existed in 1965 and today. The labeling requirements currently imposed by the FDCA, which are essentially identical to those in force in 1965, require the FDA to regulate the labeling of drugs and devices to protect the safety of consumers. See 21 U. S. C. § 352; 21 U. S. C. § 352 (1964 ed. and Supp. IV). As discussed earlier, the Act requires that all products bear "adequate directions for use . . . as are necessary for the protection of users," 21 U. S. C. § 352(f)(1); 21 U. S. C. § 352(f)(1) (1964 ed.); requires that all products provide "adequate warnings against use in those pathological [149] conditions or by children where its use may be dangerous to health," 21 U. S. C. § 352(f)(2); 21 U. S. C. § 352(f)(2) (1964 ed.); and deems a product misbranded "[i]f it is dangerous to health when used in the dosage or manner, or with the frequency or duration prescribed, recommended, or suggested in the labeling thereof," 21 U. S. C. § 352(j); 21 U. S. C. § 352(j) (1964 ed.). In this sense, the FCLAA was—and remains—incompatible with FDA regulation of tobacco products. This is not to say that the FCLAA's pre-emption provision by itself necessarily foreclosed FDA jurisdiction. See Cipollone v. Liggett Group, Inc., 505 U. S., at 518-519. But it is an important factor in assessing whether Congress ratified the agency's position—that is, whether Congress adopted a regulatory approach to the problem of tobacco and health that contemplated no role for the FDA.

Further, the FCLAA evidences Congress' intent to preclude any administrative agency from exercising significant policymaking authority on the subject of smoking and health. In addition to prohibiting any additional requirements for cigarette labeling, the FCLAA provided that "[n]o statement relating to smoking and health shall be required in the advertising of any cigarettes the packages of which are labeled in conformity with the provisions of this Act." Pub. L. 89-92, § 5(b), 79 Stat. 283. Thus, in reaction to the FTC's attempt to regulate cigarette labeling and advertising, Congress enacted a statute reserving exclusive control over both subjects to itself.

Subsequent tobacco-specific legislation followed a similar pattern. By the FCLAA's own terms, the prohibition on any additional cigarette labeling or advertising regulations relating to smoking and health was to expire July 1, 1969. See § 10, 79 Stat. 284. In anticipation of the provision's expiration, both the FCC and the FTC proposed rules governing the advertisement of cigarettes. See 34 Fed. Reg. 1959 (1969) (FCC proposed rule to "ban the broadcast of cigarette commercials by radio and television stations"); id., at 7917 [150] (FTC proposed rule requiring manufacturers to disclose on all packaging and in all print advertising "`that cigarette smoking is dangerous to health and may cause death from cancer, coronary heart disease, chronic bronchitis, pulmonary emphysema, and other diseases' "). After debating the proper role for administrative agencies in the regulation of tobacco, see generally Cigarette Labeling and Advertising— 1969: Hearings before the House Committee on Interstate and Foreign Commerce, 91st Cong., 1st Sess., pt. 2 (1969), Congress amended the FCLAA by banning cigarette advertisements "on any medium of electronic communication subject to the jurisdiction of the Federal Communications Commission" and strengthening the warning required to appear on cigarette packages. Public Health Cigarette Smoking Act of 1969, Pub. L. 91-222, §§ 4, 6, 84 Stat. 88-89. Importantly, Congress extended indefinitely the prohibition on any other regulation of cigarette labeling with respect to smoking and health (again despite the importance of labeling regulation under the FDCA). § 5(a), 84 Stat. 88 (codified at 15 U. S. C. § 1334(a)). Moreover, it expressly forbade the FTC from taking any action on its pending rule until July 1, 1971, and it required the FTC, if it decided to proceed with its rule thereafter, to notify Congress at least six months in advance of the rule's becoming effective. § 7(a), 84 Stat. 89. As the chairman of the House committee in which the bill originated stated, "the Congress—the body elected by the people— must make the policy determinations involved in this legislation—and not some agency made up of appointed officials." 116 Cong. Rec. 7920 (1970) (remarks of Rep. Staggers).

Four years later, after Congress had transferred the authority to regulate substances covered by the Hazardous Substances Act (HSA) from the FDA to the Consumer Products Safety Commission (CPSC), the American Public Health Association, joined by Senator Moss, petitioned the CPSC to regulate cigarettes yielding more than 21 milligrams of tar. See Action on Smoking and Health v. Harris, 655 F. 2d 236, [151] 241 (CADC 1980); R. Kluger, Ashes to Ashes 375-376 (1996). After the CPSC determined that it lacked authority under the HSA to regulate cigarettes, a District Court held that the HSA did, in fact, grant the CPSC such jurisdiction and ordered it to reexamine the petition. See American Public Health Association v. Consumer Product Safety Commission, [1972-1975 Transfer Binder] CCH Consumer Prod. Safety Guide ¶ 75,081 (DC 1975), vacated as moot, No. 75-1863 (CADC 1976). Before the CPSC could take any action, however, Congress mooted the issue by adopting legislation that eliminated the agency's authority to regulate "tobacco and tobacco products." Consumer Product Safety Commission Improvements Act of 1976, Pub. L. 94-284, § 3(c), 90 Stat. 503 (codified at 15 U. S. C. § 1261(f)(2)). Senator Moss acknowledged that the "legislation, in effect, reverse[d]" the District Court's decision, 121 Cong. Rec. 23563 (1975), and the FDA later observed that the episode was "particularly" "indicative of the policy of Congress to limit the regulatory authority over cigarettes by Federal Agencies," Letter to Action on Smoking and Health (ASH) Executive Director Banzhaf from FDA Comm'r Goyan (Nov. 25, 1980), App. 59. A separate statement in the Senate Report underscored that the legislation's purpose was to "unmistakably reaffirm the clear mandate of the Congress that the basic regulation of tobacco and tobacco products is governed by the legislation dealing with the subject, . . . and that any further regulation in this sensitive and complex area must be reserved for specific Congressional action." S. Rep. No. 94-251, p. 43 (1975) (additional views of Sens. Hartke, Hollings, Ford, Stevens, and Beall).

Meanwhile, the FDA continued to maintain that it lacked jurisdiction under the FDCA to regulate tobacco products as customarily marketed. In 1972, FDA Commissioner Edwards testified before Congress that "cigarettes recommended for smoking pleasure are beyond the Federal Food, Drug, and Cosmetic Act." 1972 Hearings 239, 242. He further [152] stated that the FDA believed that the Public Health Cigarette Smoking Act "demonstrates that the regulation of cigarettes is to be the domain of Congress," and that "labeling or banning cigarettes is a step that can be take[n] only by the Congress. Any such move by FDA would be inconsistent with the clear congressional intent." Ibid.

In 1977, ASH filed a citizen petition requesting that the FDA regulate cigarettes, citing many of the same grounds that motivated the FDA's rulemaking here. See Citizen Petition, No. 77P-0185 (May 26, 1977), 10 Rec. in No. 97-1604 (CA4), Tab No. 22, pp. 1-10. ASH asserted that nicotine was highly addictive and had strong physiological effects on the body; that those effects were "intended" because consumers use tobacco products precisely to obtain those effects; and that tobacco causes thousands of premature deaths annually. Ibid. In denying ASH's petition, FDA Commissioner Kennedy stated that "[t]he interpretation of the Act by FDA consistently has been that cigarettes are not a drug unless health claims are made by the vendors." Letter to ASH Executive Director Banzhaf (Dec. 5, 1977), App. 47. After the matter proceeded to litigation, the FDA argued in its brief to the Court of Appeals that "cigarettes are not comprehended within the statutory definition of the term `drug' absent objective evidence that vendors represent or intend that their products be used as a drug." Brief for Appellee in Action on Smoking and Health v. Harris, 655 F. 2d 236 (CADC 1980), 9 Rec. in No. 97-1604 (CA4), Tab No. 4, at 27-28. The FDA also contended that Congress had "long been aware that the FDA does not consider cigarettes to be within its regulatory authority in the absence of health claims made on behalf of the manufacturer or vendor," and that, because "Congress has never acted to disturb the agency's interpretation," it had "acquiesced in the FDA's interpretation of the statutory limits on its authority to regulate cigarettes." Id., at 23, 27, n. 23. The Court of Appeals upheld the FDA's position, concluding that "[i]f the statute [153] requires expansion, that is the job of Congress." Action on Smoking and Health v. Harris, 655 F. 2d, at 243. In 1980, the FDA also denied a request by ASH to commence rulemaking proceedings to establish the agency's jurisdiction to regulate cigarettes as devices. See Letter to ASH Executive Director Banzhaf from FDA Comm'r Goyan (Nov. 25, 1980), App. 50-51. The agency stated that "[i]nsofar as rulemaking would relate to cigarettes or attached filters as customarily marketed, we have concluded that FDA has no jurisdiction under section 201(h) of the Act [21 U. S. C. § 321(h)]." Id., at 67.

In 1983, Congress again considered legislation on the subject of smoking and health. HHS Assistant Secretary Brandt testified that, in addition to being "a major cause of cancer," smoking is a "major cause of heart disease" and other serious illnesses, and can result in "unfavorable pregnancy outcomes." 1983 House Hearings 19-20. He also stated that it was "well-established that cigarette smoking is a drug dependence, and that smoking is addictive for many people." Id., at 20. Nonetheless, Assistant Secretary Brandt maintained that "the issue of regulation of tobacco . . . is something that Congress has reserved to itself, and we do not within the Department have the authority to regulate nor are we seeking such authority." Id., at 74. He also testified before the Senate, stating that, despite the evidence of tobacco's health effects and addictiveness, the Department's view was that "Congress has assumed the responsibility of regulating . . . cigarettes." Smoking Prevention and Education Act: Hearings on S. 772 before the Senate Committee on Labor and Human Resources, 98th Cong., 1st Sess., 56 (1983) (hereinafter 1983 Senate Hearings).

Against this backdrop, Congress enacted three additional tobacco-specific statutes over the next four years that incrementally expanded its regulatory scheme for tobacco products. In 1983, Congress adopted the Alcohol and Drug Abuse Amendments, Pub. L. 98-24, 97 Stat. 175 (codified at [154] 42 U. S. C. § 290aa et seq. ), which require the Secretary of HHS to report to Congress every three years on the "addictive property of tobacco" and to include recommendations for action that the Secretary may deem appropriate. A year later, Congress enacted the Comprehensive Smoking Education Act, Pub. L. 98-474, 98 Stat. 2200, which amended the FCLAA by again modifying the prescribed warning. Notably, during debate on the Senate floor, Senator Hawkins argued that the FCLAA was necessary in part because "[u]nder the Food, Drug and Cosmetic Act, the Congress exempted tobacco products." 130 Cong. Rec. 26953 (1984). And in 1986, Congress enacted the Comprehensive Smokeless Tobacco Health Education Act of 1986 (CSTHEA), Pub. L. 99-252, 100 Stat. 30 (codified at 15 U. S. C. § 4401 et seq. ), which essentially extended the regulatory provisions of the FCLAA to smokeless tobacco products. Like the FCLAA, the CSTHEA provided that "[n]o statement relating to the use of smokeless tobacco products and health, other than the statements required by [the Act], shall be required by any Federal agency to appear on any package . . . of a smokeless tobacco product." § 7(a), 100 Stat. 34 (codified at 15 U. S. C. § 4406(a)). Thus, as with cigarettes, Congress reserved for itself an aspect of smokeless tobacco regulation that is particularly important to the FDCA's regulatory scheme.

In 1988, the Surgeon General released a report summarizing the abundant scientific literature demonstrating that "[c]igarettes and other forms of tobacco are addicting," and that "nicotine is psychoactive" and "causes physical dependence characterized by a withdrawal syndrome that usually accompanies nicotine abstinence." 1988 Surgeon General's Report 14. The report further concluded that the "pharmacologic and behavioral processes that determine tobacco addiction are similar to those that determine addiction to drugs such as heroin and cocaine." Id., at 15. In the same year, FDA Commissioner Young stated before Congress that "it doesn't look like it is possible to regulate [tobacco] under the [155] Food, Drug and Cosmetic Act even though smoking, I think, has been widely recognized as being harmful to human health." Rural Development, Agriculture, and Related Agencies Appropriations for 1989: Hearings before a Subcommittee of the House Committee on Appropriations, 100th Cong., 2d Sess., 409 (1988). At the same hearing, the FDA's General Counsel testified that "what is fairly important in FDA law is whether a product has a therapeutic purpose," and "[c]igarettes themselves are not used for a therapeutic purpose as that concept is ordinarily understood." Id., at 410. Between 1987 and 1989, Congress considered three more bills that would have amended the FDCA to grant the FDA jurisdiction to regulate tobacco products. See H. R. 3294, 100th Cong., 1st Sess. (1987); H. R. 1494, 101st Cong., 1st Sess. (1989); S. 769, 101st Cong., 1st Sess. (1989). As before, Congress rejected the proposals. In 1992, Congress instead adopted the Alcohol, Drug Abuse, and Mental Health Administration Reorganization Act, Pub. L. 102-321, § 202, 106 Stat. 394 (codified at 42 U. S. C. § 300x et seq. ), which creates incentives for States to regulate the retail sale of tobacco products by making States' receipt of certain block grants contingent on their prohibiting the sale of tobacco products to minors.

Taken together, these actions by Congress over the past 35 years preclude an interpretation of the FDCA that grants the FDA jurisdiction to regulate tobacco products. We do not rely on Congress' failure to act—its consideration and rejection of bills that would have given the FDA this authority—in reaching this conclusion. Indeed, this is not a case of simple inaction by Congress that purportedly represents its acquiescence in an agency's position. To the contrary, Congress has enacted several statutes addressing the particular subject of tobacco and health, creating a distinct regulatory scheme for cigarettes and smokeless tobacco. In doing so, Congress has been aware of tobacco's health hazards and its pharmacological effects. It has also enacted this legislation [156] against the background of the FDA repeatedly and consistently asserting that it lacks jurisdiction under the FDCA to regulate tobacco products as customarily marketed. Further, Congress has persistently acted to preclude a meaningful role for any administrative agency in making policy on the subject of tobacco and health. Moreover, the substance of Congress' regulatory scheme is, in an important respect, incompatible with FDA jurisdiction. Although the supervision of product labeling to protect consumer health is a substantial component of the FDA's regulation of drugs and devices, see 21 U. S. C. § 352 (1994 ed. and Supp. III), the FCLAA and the CSTHEA explicitly prohibit any federal agency from imposing any health-related labeling requirements on cigarettes or smokeless tobacco products, see 15 U. S. C. §§ 1334(a), 4406(a).

Under these circumstances, it is clear that Congress' tobacco-specific legislation has effectively ratified the FDA's previous position that it lacks jurisdiction to regulate tobacco. As in Bob Jones Univ. v. United States, 461 U. S. 574 (1983), "[i]t is hardly conceivable that Congress—and in this setting, any Member of Congress—was not abundantly aware of what was going on." Id., at 600-601. Congress has affirmatively acted to address the issue of tobacco and health, relying on the representations of the FDA that it had no authority to regulate tobacco. It has created a distinct scheme to regulate the sale of tobacco products, focused on labeling and advertising, and premised on the belief that the FDA lacks such jurisdiction under the FDCA. As a result, Congress' tobacco-specific statutes preclude the FDA from regulating tobacco products as customarily marketed.

Although the dissent takes issue with our discussion of the FDA's change in position, post, at 186-189, our conclusion does not rely on the fact that the FDA's assertion of jurisdiction represents a sharp break with its prior interpretation of the FDCA. Certainly, an agency's initial interpretation of a statute that it is charged with administering is not "carved [157] in stone." Chevron, 467 U. S., at 863; see also Smiley v. Citibank (South Dakota), N. A., 517 U. S. 735, 742 (1996). As we recognized in Motor Vehicle Mfrs. Assn. of United States, Inc. v. State Farm Mut. Automobile Ins. Co., 463 U. S. 29 (1983), agencies "must be given ample latitude to `adapt their rules and policies to the demands of changing circumstances.' " Id., at 42 (quoting Permian Basin Area Rate Cases, 390 U. S. 747, 784 (1968)). The consistency of the FDA's prior position is significant in this case for a different reason: It provides important context to Congress' enactment of its tobacco-specific legislation. When the FDA repeatedly informed Congress that the FDCA does not grant it the authority to regulate tobacco products, its statements were consistent with the agency's unwavering position since its inception, and with the position that its predecessor agency had first taken in 1914. Although not crucial, the consistency of the FDA's prior position bolsters the conclusion that when Congress created a distinct regulatory scheme addressing the subject of tobacco and health, it understood that the FDA is without jurisdiction to regulate tobacco products and ratified that position.

The dissent also argues that the proper inference to be drawn from Congress' tobacco-specific legislation is "critically ambivalent." Post, at 182. We disagree. In that series of statutes, Congress crafted a specific legislative response to the problem of tobacco and health, and it did so with the understanding, based on repeated assertions by the FDA, that the agency has no authority under the FDCA to regulate tobacco products. Moreover, Congress expressly pre-empted any other regulation of the labeling of tobacco products concerning their health consequences, even though the oversight of labeling is central to the FDCA's regulatory scheme. And in addressing the subject, Congress consistently evidenced its intent to preclude any federal agency from exercising significant policymaking authority in the area. Under these circumstances, we believe the appropriate [158] inference—that Congress intended to ratify the FDA's prior position that it lacks jurisdiction—is unmistakable.

The dissent alternatively argues that, even if Congress' subsequent tobacco-specific legislation did, in fact, ratify the FDA's position, that position was merely a contingent disavowal of jurisdiction. Specifically, the dissent contends that "the FDA's traditional view was largely premised on a perceived inability to prove the necessary statutory `intent' requirement." Post, at 189-190. A fair reading of the FDA's representations prior to 1995, however, demonstrates that the agency's position was essentially unconditional. See, e. g., 1972 Hearings 239, 242 (statement of Comm'r Edwards) ("[R]egulation of cigarettes is to be the domain of Congress," and "[a]ny such move by FDA would be inconsistent with the clear congressional intent"); 1983 House Hearings 74 (statement of Assistant Secretary Brandt) ("[T]he issue of regulation of tobacco . . . is something that Congress has reserved to itself"); 1983 Senate Hearings 56 (statement of Assistant Secretary Brandt) ("Congress has assumed the responsibility of regulating . . . cigarettes"); Brief for Appellee in Action on Smoking and Health v. Harris, 655 F. 2d 236 (CADC 1980), 9 Rec. in No. 97-1604 (CA4), Tab No. 4, at 27, n. 23 (because "Congress has never acted to disturb the agency's interpretation," it "acquiesced in the FDA's interpretation"). To the extent the agency's position could be characterized as equivocal, it was only with respect to the well-established exception of when the manufacturer makes express claims of therapeutic benefit. See, e. g., 1965 Hearings 193 (statement of Deputy Comm'r Rankin) ("The Food and Drug Administration has no jurisdiction under the Food, Drug, and Cosmetic Act over tobacco, unless it bears drug claims"); Letter to ASH Executive Director Banzhaf from FDA Comm'r Kennedy (Dec. 5, 1977), App. 47 ("The interpretation of the Act by FDA consistently has been that cigarettes are not a drug unless health claims are made by the vendors"); Letter to ASH Executive Director Banzhaf from [159] FDA Comm'r Goyan (Nov. 25, 1980), id., at 67 ("Insofar as rulemaking would relate to cigarettes or attached filters as customarily marketed, we have concluded that FDA has no jurisdiction"). Thus, what Congress ratified was the FDA's plain and resolute position that the FDCA gives the agency no authority to regulate tobacco products as customarily marketed.

C

Finally, our inquiry into whether Congress has directly spoken to the precise question at issue is shaped, at least in some measure, by the nature of the question presented. Deference under Chevron to an agency's construction of a statute that it administers is premised on the theory that a statute's ambiguity constitutes an implicit delegation from Congress to the agency to fill in the statutory gaps. See Chevron, supra, at 844. In extraordinary cases, however, there may be reason to hesitate before concluding that Congress has intended such an implicit delegation. Cf. Breyer, Judicial Review of Questions of Law and Policy, 38 Admin. L. Rev. 363, 370 (1986) ("A court may also ask whether the legal question is an important one. Congress is more likely to have focused upon, and answered, major questions, while leaving interstitial matters to answer themselves in the course of the statute's daily administration").

This is hardly an ordinary case. Contrary to its representations to Congress since 1914, the FDA has now asserted jurisdiction to regulate an industry constituting a significant portion of the American economy. In fact, the FDA contends that, were it to determine that tobacco products provide no "reasonable assurance of safety," it would have the authority to ban cigarettes and smokeless tobacco entirely. See Brief for Petitioners 35-36; Reply Brief for Petitioners 14. Owing to its unique place in American history and society, tobacco has its own unique political history. Congress, for better or for worse, has created a distinct regulatory scheme for tobacco products, squarely rejected proposals to [160] give the FDA jurisdiction over tobacco, and repeatedly acted to preclude any agency from exercising significant policymaking authority in the area. Given this history and the breadth of the authority that the FDA has asserted, we are obliged to defer not to the agency's expansive construction of the statute, but to Congress' consistent judgment to deny the FDA this power.

Our decision in MCI Telecommunications Corp. v. American Telephone & Telegraph Co., 512 U. S. 218 (1994), is instructive. That case involved the proper construction of the term "modify" in § 203(b) of the Communications Act of 1934. The FCC contended that, because the Act gave it the discretion to "modify any requirement" imposed under the statute, it therefore possessed the authority to render voluntary the otherwise mandatory requirement that long distance carriers file their rates. Id., at 225. We rejected the FCC's construction, finding "not the slightest doubt" that Congress had directly spoken to the question. Id., at 228. In reasoning even more apt here, we concluded that "[i]t is highly unlikely that Congress would leave the determination of whether an industry will be entirely, or even substantially, rateregulated to agency discretion—and even more unlikely that it would achieve that through such a subtle device as permission to `modify' rate-filing requirements." Id., at 231.

As in MCI, we are confident that Congress could not have intended to delegate a decision of such economic and political significance to an agency in so cryptic a fashion. To find that the FDA has the authority to regulate tobacco products, one must not only adopt an extremely strained understanding of "safety" as it is used throughout the Act—a concept central to the FDCA's regulatory scheme—but also ignore the plain implication of Congress' subsequent tobaccospecific legislation. It is therefore clear, based on the FDCA's overall regulatory scheme and the subsequent tobacco legislation, that Congress has directly spoken to the [161] question at issue and precluded the FDA from regulating tobacco products.

* * *

By no means do we question the seriousness of the problem that the FDA has sought to address. The agency has amply demonstrated that tobacco use, particularly among children and adolescents, poses perhaps the single most significant threat to public health in the United States. Nonetheless, no matter how "important, conspicuous, and controversial" the issue, and regardless of how likely the public is to hold the Executive Branch politically accountable, post, at 190, an administrative agency's power to regulate in the public interest must always be grounded in a valid grant of authority from Congress. And "`[i]n our anxiety to effectuate the congressional purpose of protecting the public, we must take care not to extend the scope of the statute beyond the point where Congress indicated it would stop.' " United States v. Article of Drug . . . Bacto-Unidisk, 394 U. S. 784, 800 (1969) (quoting 62 Cases of Jam v. United States, 340 U. S. 593, 600 (1951)). Reading the FDCA as a whole, as well as in conjunction with Congress' subsequent tobaccospecific legislation, it is plain that Congress has not given the FDA the authority that it seeks to exercise here. For these reasons, the judgment of the Court of Appeals for the Fourth Circuit is affirmed.

It is so ordered.

Justice Breyer, with whom Justice Stevens, Justice Souter, and Justice Ginsburg join, dissenting.

The Food and Drug Administration (FDA) has the authority to regulate "articles (other than food) intended to affect the structure or any function of the body . . . ." Federal Food, Drug, and Cosmetic Act (FDCA), 21 U. S. C. § 321(g)(1)(C). Unlike the majority, I believe that tobacco products fit within this statutory language.

[162] In its own interpretation, the majority nowhere denies the following two salient points. First, tobacco products (including cigarettes) fall within the scope of this statutory definition, read literally. Cigarettes achieve their moodstabilizing effects through the interaction of the chemical nicotine and the cells of the central nervous system. Both cigarette manufacturers and smokers alike know of, and desire, that chemically induced result. Hence, cigarettes are "intended to affect" the body's "structure" and "function," in the literal sense of these words.

Second, the statute's basic purpose—the protection of public health—supports the inclusion of cigarettes within its scope. See United States v. Article of Drug . . . BactoUnidisk, 394 U. S. 784, 798 (1969) (FDCA "is to be given a liberal construction consistent with [its] overriding purpose to protect the public health " (emphasis added)). Unregulated tobacco use causes "[m]ore than 400,000 people [to] die each year from tobacco-related illnesses, such as cancer, respiratory illnesses, and heart disease." 61 Fed. Reg. 44398 (1996). Indeed, tobacco products kill more people in this country every year "than . . . AIDS . . . , car accidents, alcohol, homicides, illegal drugs, suicides, and fires, combined. " Ibid. (emphasis added).

Despite the FDCA's literal language and general purpose (both of which support the FDA's finding that cigarettes come within its statutory authority), the majority nonetheless reads the statute as excluding tobacco products for two basic reasons:

(1) the FDCA does not "fit" the case of tobacco because the statute requires the FDA to prohibit dangerous drugs or devices (like cigarettes) outright, and the agency concedes that simply banning the sale of cigarettes is not a proper remedy, ante, at 139-141; and (2) Congress has enacted other statutes, which, when viewed in light of the FDA's long history of denying [163] tobacco-related jurisdiction and considered together with Congress' failure explicitly to grant the agency tobacco-specific authority, demonstrate that Congress did not intend for the FDA to exercise jurisdiction over tobacco, ante, at 155-156.

In my view, neither of these propositions is valid. Rather, the FDCA does not significantly limit the FDA's remedial alternatives. See infra, at 174-181. And the later statutes do not tell the FDA it cannot exercise jurisdiction, but simply leave FDA jurisdictional law where Congress found it. See infra, at 181-186; cf. Food and Drug Administration Modernization Act of 1997, 111 Stat. 2380 (codified at note following 21 U. S. C. § 321 (1994 ed., Supp. III)) (statute "shall" not "be construed to affect the question of whether" the FDA "has any authority to regulate any tobacco product").

The bulk of the opinion that follows will explain the basis for these latter conclusions. In short, I believe that the most important indicia of statutory meaning—language and purpose—along with the FDCA's legislative history (described briefly in Part I) are sufficient to establish that the FDA has authority to regulate tobacco. The statute-specific arguments against jurisdiction that the tobacco companies and the majority rely upon (discussed in Part II) are based on erroneous assumptions and, thus, do not defeat the jurisdiction-supporting thrust of the FDCA's language and purpose. The inferences that the majority draws from later legislative history are not persuasive, since (as I point out in Part III) one can just as easily infer from the later laws that Congress did not intend to affect the FDA's tobacco-related authority at all. And the fact that the FDA changed its mind about the scope of its own jurisdiction is legally insignificant because (as Part IV establishes) the agency's reasons for changing course are fully justified. Finally, as I explain in Part V, the degree of accountability that likely will attach to the FDA's action in this case should alleviate any concern [164] that Congress, rather than an administrative agency, ought to make this important regulatory decision.

I

Before 1938, the federal Pure Food and Drug Act contained only two jurisdictional definitions of "drug":

"[1] medicines and preparations recognized in the United States Pharmacopoeia or National Formulary . . . and [2] any substance or mixture of substances intended to be used for the cure, mitigation, or prevention of disease." Act of June 30, 1906, ch. 3915, § 6, 34 Stat. 769.

In 1938, Congress added a third definition, relevant here:

"(3) articles (other than food) intended to affect the structure or any function of the body . . . ." Act of June 25, 1938, ch. 675, § 201(g), 52 Stat. 1041 (codified at 21 U. S. C. § 321(g)(1)(C)).

It also added a similar definition in respect to a "device." See § 201(h), 52 Stat. 1041 (codified at 21 U. S. C. § 321(h)). As I have mentioned, the literal language of the third definition and the FDCA's general purpose both strongly support a projurisdiction reading of the statute. See supra, at 161-162.

The statute's history offers further support. The FDA drafted the new language, and it testified before Congress that the third definition would expand the FDCA's jurisdictional scope significantly. See Hearings on S. 1944 before a Subcommittee of the Senate Committee on Commerce, 73d Cong., 2d Sess., 15-16 (1933), reprinted in 1 FDA, Legislative History of the Federal Food, Drug, and Cosmetic Act and Its Amendments 107-108 (1979) (hereinafter Leg. Hist.). Indeed, "[t]he purpose" of the new definition was to "make possible the regulation of a great many products that have been found on the market that cannot be alleged to be treatments for diseased conditions." Id., at 108. While the drafters focused specifically upon the need to give the FDA jurisdiction [165] over "slenderizing" products such as "antifat remedies," ibid., they were aware that, in doing so, they had created what was "admittedly an inclusive, a wide definition," id., at 107. And that broad language was included deliberately, so that jurisdiction could be had over "all substances and preparations, other than food, and all devices intended to affect the structure or any function of the body . . . ." Ibid. (emphasis added); see also Hearings on S. 2800 before the Senate Committee on Commerce, 73d Cong., 2d Sess., 516 (1934), reprinted in 2 Leg. Hist. 519 (statement of then-FDA Chief Walter Campbell acknowledging that "[t]his definition of `drugs' is all-inclusive").

After studying the FDCA's history, experts have written that the statute "is a purposefully broad delegation of discretionary powers by Congress," 1 J. O'Reilly, Food and Drug Administration § 6.01, p. 6-1 (2d ed. 1995) (hereinafter O'Reilly), and that, in a sense, the FDCA "must be regarded as a constitution " that "establish[es] general principles" and "permit[s] implementation within broad parameters" so that the FDA can "implement these objectives through the most effective and efficient controls that can be devised." Hutt, Philosophy of Regulation Under the Federal Food, Drug and Cosmetic Act, 28 Food Drug Cosm. L. J. 177, 178-179 (1973) (emphasis added). This Court, too, has said that the

"historical expansion of the definition of drug, and the creation of a parallel concept of devices, clearly show . . . that Congress fully intended that the Act's coverage be as broad as its literal language indicates—and equally clearly, broader than any strict medical definition might otherwise allow." Bacto-Unidisk, 394 U. S., at 798.

That Congress would grant the FDA such broad jurisdictional authority should surprise no one. In 1938, the President and much of Congress believed that federal administrative agencies needed broad authority and would exercise that authority wisely—a view embodied in much Second New [166] Deal legislation. Cf. Gray v. Powell, 314 U. S. 402, 411-412 (1941) (Congress "could have legislated specifically" but decided "to delegate that function to those whose experience in a particular field gave promise of a better informed, more equitable" determination). Thus, at around the same time that it added the relevant language to the FDCA, Congress enacted laws granting other administrative agencies even broader powers to regulate much of the Nation's transportation and communication. See, e. g., Civil Aeronautics Act of 1938, ch. 601, § 401(d)(1), 52 Stat. 987 (Civil Aeronautics Board to regulate airlines within confines of highly general "public convenience and necessity" standard); Motor Carrier Act of 1935, ch. 498, § 204(a)(1), 49 Stat. 546 (Interstate Commerce Commission to establish "reasonable requirements" for trucking); Communications Act of 1934, ch. 652, § 201(a), 48 Stat. 1070 (Federal Communications Commission (FCC) to regulate radio, later television, within confines of even broader "public interest" standard). Why would the 1938 New Deal Congress suddenly have hesitated to delegate to so well established an agency as the FDA all of the discretionary authority that a straightforward reading of the relevant statutory language implies?

Nor is it surprising that such a statutory delegation of power could lead after many years to an assertion of jurisdiction that the 1938 legislators might not have expected. Such a possibility is inherent in the very nature of a broad delegation. In 1938, it may well have seemed unlikely that the FDA would ever bring cigarette manufacturers within the FDCA's statutory language by proving that cigarettes produce chemical changes in the body and that the makers "intended" their product chemically to affect the body's "structure" or "function." Or, back then, it may have seemed unlikely that, even assuming such proof, the FDA actually would exercise its discretion to regulate so popular a product. See R. Kluger, Ashes to Ashes 105 (1997) (in the 1930's "Americans were in love with smoking . . .").

[167] But it should not have seemed unlikely that, assuming the FDA decided to regulate and proved the particular jurisdictional prerequisites, the courts would rule such a jurisdictional assertion fully authorized. Cf. United States v. Southwestern Cable Co., 392 U. S. 157, 172 (1968) (reading Communications Act of 1934 as authorizing FCC jurisdiction to regulate cable systems while noting that "Congress could not in 1934 have foreseen the development of" advanced communications systems). After all, this Court has read more narrowly phrased statutes to grant what might have seemed even more unlikely assertions of agency jurisdiction. See, e. g., Permian Basin Area Rate Cases, 390 U. S. 747, 774-777 (1968) (statutory authority to regulate interstate "transportation" of natural gas includes authority to regulate "prices" charged by field producers); Phillips Petroleum Co. v. Wisconsin, 347 U. S. 672, 677-684 (1954) (independent gas producer subject to regulation despite Natural Gas Act's express exemption of gathering and production facilities).

I shall not pursue these general matters further, for neither the companies nor the majority denies that the FDCA's literal language, its general purpose, and its particular legislative history favor the FDA's present jurisdictional view. Rather, they have made several specific arguments in support of one basic contention: Even if the statutory delegation is broad, it is not broad enough to include tobacco. I now turn to each of those arguments.

II

A

The tobacco companies contend that the FDCA's words cannot possibly be read to mean what they literally say. The statute defines "device," for example, as "an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article . . . intended to affect the structure or any function of the body . . . ." 21 [168] U. S. C. § 321(h). Taken literally, this definition might include everything from room air conditioners to thermal pajamas. The companies argue that, to avoid such a result, the meaning of "drug" or "device" should be confined to medical or therapeutic products, narrowly defined. See Brief for Respondent United States Tobacco Co. 8-9.

The companies may well be right that the statute should not be read to cover room air conditioners and winter underwear. But I do not agree that we must accept their proposed limitation. For one thing, such a cramped reading contravenes the established purpose of the statutory language. See Bacto-Unidisk, 394 U. S., at 798 (third definition is "clearly, broader than any strict medical definition"); 1 Leg. Hist. 108 (definition covers products "that cannot be alleged to be treatments for diseased conditions"). For another, the companies' restriction would render the other two "drug" definitions superfluous. See 21 U. S. C. §§ 321(g)(1)(A), (g)(1)(B) (covering articles in the leading pharmacology compendia and those "intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease").

Most importantly, the statute's language itself supplies a different, more suitable, limitation: that a "drug" must be a chemical agent. The FDCA's "device" definition states that an article which affects the structure or function of the body is a "device" only if it "does not achieve its primary intended purposes through chemical action within . . . the body," and "is not dependent upon being metabolized for the achievement of its primary intended purposes." § 321(h) (emphasis added). One can readily infer from this language that at least an article that does achieve its primary purpose through chemical action within the body and that is dependent upon being metabolized is a "drug," provided that it otherwise falls within the scope of the "drug" definition. And one need not hypothesize about air conditioners or thermal [169] pajamas to recognize that the chemical nicotine, an important tobacco ingredient, meets this test.

Although I now oversimplify, the FDA has determined that once nicotine enters the body, the blood carries it almost immediately to the brain. See 61 Fed. Reg. 44698-44699 (1966). Nicotine then binds to receptors on the surface of brain cells, setting off a series of chemical reactions that alter one's mood and produce feelings of sedation and stimulation. See id., at 44699, 44739. Nicotine also increases the number of nicotinic receptors on the brain's surface, and alters its normal electrical activity. See id., at 44739. And nicotine stimulates the transmission of a natural chemical that "rewards" the body with pleasurable sensations (dopamine), causing nicotine addiction. See id., at 44700, 44721-44722. The upshot is that nicotine stabilizes mood, suppresses appetite, tranquilizes, and satisfies a physical craving that nicotine itself has helped to create—all through chemical action within the body after being metabolized.

This physiology—and not simply smoker psychology— helps to explain why as many as 75% of adult smokers believe that smoking "reduce[s] nervous irritation," 60 Fed. Reg. 41579 (1995); why 73% of young people (10- to 22-yearolds) who begin smoking say they do so for "relaxation," 61 Fed. Reg. 44814 (1996); and why less than 3% of smokers succeed in quitting each year, although 70% want to quit, id., at 44704. That chemistry also helps to explain the Surgeon General's findings that smokers believe "smoking [makes them] feel better" and smoke more "in situations involving negative mood." Id., at 44814. And, for present purposes, that chemistry demonstrates that nicotine affects the "structure" and "function" of the body in a manner that is quite similar to the effects of other regulated substances. See id., at 44667 (FDA regulates Valium, NoDoz, weight-loss products). Indeed, addiction, sedation, stimulation, and weight loss are precisely the kinds of product effects that the FDA typically reviews and controls. And, since the nicotine in cigarettes [170] plainly is not a "food," its chemical effects suffice to establish that it is as a "drug" (and the cigarette that delivers it a drug-delivery "device") for the purpose of the FDCA.

B

The tobacco companies' principal definitional argument focuses upon the statutory word "intended." See 21 U. S. C. § 321(g)(1)(C). The companies say that "intended" in this context is a term of art. See Brief for Respondent Brown & Williamson Tobacco Corp. 2. They assert that the statutory word "intended" means that the product's maker has made an express claim about the effect that its product will have on the body. Ibid. Indeed, according to the companies, the FDA's inability to prove that cigarette manufacturers make such claims is precisely why that agency historically has said it lacked the statutory power to regulate tobacco. See id., at 19-20.

The FDCA, however, does not use the word "claimed"; it uses the word "intended." And the FDA long ago issued regulations that say the relevant "intent" can be shown not only by a manufacturer's "expressions," but also "by the circumstances surrounding the distribution of the article." 41 Fed. Reg. 6896 (1976) (codified at 21 CFR § 801.4 (1999)); see also 41 Fed. Reg. 6896 (1976) ("objective intent" shown if "article is, with the knowledge [of its makers], offered and used" for a particular purpose). Thus, even in the absence of express claims, the FDA has regulated products that affect the body if the manufacturer wants, and knows, that consumers so use the product. See, e. g., 60 Fed. Reg. 41527-41531 (1995) (describing agency's regulation of topical hormones, sunscreens, fluoride, tanning lamps, thyroid in food supplements, novelty condoms—all marketed without express claims); see also 1 O'Reilly § 13.04, at 13-15 ("Sometimes the very nature of the material makes it a drug . . .").

Courts ordinarily reverse an agency interpretation of this kind only if Congress has clearly answered the interpretive [171] question or if the agency's interpretation is unreasonable. Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837, 842-843 (1984). The companies, in an effort to argue the former, point to language in the legislative history tying the word "intended" to a technical concept called "intended use." But nothing in Congress' discussion either of "intended" or "intended use" suggests that an express claim (which often shows intent) is always necessary. Indeed, the primary statement to which the companies direct our attention says only that a manufacturer can determine what kind of regulation applies—"food" or "drug"—because, "through his representations in connection with its sale, [the manufacturer] can determine" whether an article is to be used as a "food," as a "drug," or as "both." S. Rep. No. 361, 74th Cong., 1st Sess., 4 (1935), reprinted in 3 Leg. Hist. 696.

Nor is the FDA's "objective intent" interpretation unreasonable. It falls well within the established scope of the ordinary meaning of the word "intended." See Agnew v. United States, 165 U. S. 36, 53 (1897) (intent encompasses the known consequences of an act). And the companies acknowledge that the FDA can regulate a drug-like substance in the ordinary circumstance, i. e., where the manufacturer makes an express claim, so it is not unreasonable to conclude that the agency retains such power where a product's effects on the body are so well known (say, like those of aspirin or calamine lotion), that there is no need for express representations because the product speaks for itself.

The companies also cannot deny that the evidence of their intent is sufficient to satisfy the statutory word "intended" as the FDA long has interpreted it. In the first place, there was once a time when they actually did make express advertising claims regarding tobacco's mood-stabilizing and weight-reducing properties—and historical representations can portend present expectations. In the late 1920's, for example, the American Tobacco Company urged weightconscious smokers to "`Reach for a Lucky instead of a [172] sweet.' " Kluger, Ashes to Ashes, at 77-78. The advertisements of R J Reynolds (RJR) emphasized mood stability by depicting a pilot remarking that "`It Takes Steady Nerves to Fly the Mail at Night . . . . That's why I smoke Camels. And I smoke plenty!' " Id., at 86. RJR also advertised the stimulating quality of cigarettes, stating in one instance that "`You get a Lift with a Camel,' " and, in another, that Camels are "`A Harmless Restoration of the Flow of Natural Body Energy.' " Id., at 87. And claims of medical proof of mildness (and of other beneficial effects) once were commonplace. See, e. g., id., at 93 (Brown & Williamson advertised Koolbrand mentholated cigarettes as "a tonic to hot, tired throats"); id., at 101, 131 (Philip Morris contended that "`[r]ecognized laboratory tests have conclusively proven the advantage of Phillip [sic] Morris' "); id., at 88 (RJR proclaimed "`For Digestion's sake, smoke Camels! . . . Camels make mealtime more pleasant—digestion is stimulated—alkalinity increased' "). Although in recent decades cigarette manufacturers have stopped making express health claims in their advertising, consumers have come to understand what the companies no longer need to express—that through chemical action cigarettes stabilize mood, sedate, stimulate, and help suppress appetite.

Second, even though the companies refused to acknowledge publicly (until only very recently) that the nicotine in cigarettes has chemically induced, and habit-forming, effects, see, e. g., Regulation of Tobacco Products (Part 1): Hearings before the House Subcommittee on Health and the Environment, 103d Cong., 2d Sess., 628 (1994) (hereinafter 1994 Hearings) (heads of seven major tobacco companies testified under oath that they believed "nicotine is not addictive" (emphasis added)), the FDA recently has gained access to solid, documentary evidence proving that cigarette manufacturers have long known tobacco produces these effects within the body through the metabolizing of chemicals, and that they [173] have long wanted their products to produce those effects in this way.

For example, in 1972, a tobacco-industry scientist explained that "`[s]moke is beyond question the most optimized vehicle of nicotine,' " and "`the cigarette is the most optimized dispenser of smoke.' " 61 Fed. Reg. 44856 (1996) (emphasis deleted). That same scientist urged company executives to

"`[t]hink of the cigarette pack as a storage container for a day's supply of nicotine. . . . Think of the cigarette as a dispenser for a dose unit of nicotine [and] [t]hink of a puff of smoke as the vehicle of nicotine.' " Ibid. (Philip Morris) (emphasis deleted).

That same year, other tobacco industry researchers told their superiors that

"`in different situations and at different dose levels, nicotine appears to act as a stimulant, depressant, tranquilizer, psychic energizer, appetite reducer, anti-fatigue agent, or energizer. . . . Therefore, [tobacco] products may, in a sense, compete with a variety of other products with certain types of drug action.' " Id., at 44669 (RJR) (emphasis deleted).

A draft report prepared by authorities at Philip Morris said that nicotine

"`is a physiologically active, nitrogen containing substance [similar to] quinine, cocaine, atropine and morphine. [And] [w]hile each of these [other] substances can be used to affect human physiology, nicotine has a particularly broad range of influence.' " Id., at 44668-44669.

And a 1980 manufacturer's study stated that

"`the pharmacological response of smokers to nicotine is believed to be responsible for an individual's smoking [174] behaviour, providing the motivation for and the degree of satisfaction required by the smoker.' " Id., at 44936 (Brown & Williamson).

With such evidence, the FDA has more than sufficiently established that the companies "intend" their products to "affect" the body within the meaning of the FDCA.

C

The majority nonetheless reaches the "inescapable conclusion" that the language and structure of the FDCA as a whole "simply do not fit" the kind of public health problem that tobacco creates. Ante, at 143. That is because, in the majority's view, the FDCA requires the FDA to ban outright "dangerous" drugs or devices (such as cigarettes); yet, the FDA concedes that an immediate and total cigarette-sale ban is inappropriate. Ibid.

This argument is curious because it leads with similarly "inescapable" force to precisely the opposite conclusion, namely, that the FDA does have jurisdiction but that it must ban cigarettes. More importantly, the argument fails to take into account the fact that a statute interpreted as requiring the FDA to pick a more dangerous over a less dangerous remedy would be a perverse statute, causing, rather than preventing, unnecessary harm whenever a total ban is likely the more dangerous response. And one can at least imagine such circumstances.

Suppose, for example, that a commonly used, mildly addictive sleeping pill (or, say, a kind of popular contact lens), plainly within the FDA's jurisdiction, turned out to pose serious health risks for certain consumers. Suppose further that many of those addicted consumers would ignore an immediate total ban, turning to a potentially more dangerous black-market substitute, while a less draconian remedy (say, adequate notice) would wean them gradually away to a safer product. Would the FDCA still force the FDA to impose [175] the more dangerous remedy? For the following reasons, I think not.

First, the statute's language does not restrict the FDA's remedial powers in this way. The FDCA permits the FDA to regulate a "combination product"—i. e., a "device" (such as a cigarette) that contains a "drug" (such as nicotine)— under its "device" provisions. 21 U. S. C. § 353(g)(1). And the FDCA's "device" provisions explicitly grant the FDA wide remedial discretion. For example, where the FDA cannot "otherwise" obtain "reasonable assurance" of a device's "safety and effectiveness," the agency may restrict by regulation a product's "sale, distribution, or use" upon "such . . . conditions as the Secretary may prescribe." § 360j(e)(1) (emphasis added). And the statutory section that most clearly addresses the FDA's power to ban (entitled "Banned devices") says that, where a device presents "an unreasonable and substantial risk of illness or injury," the Secretary "may "—not must —"initiate a proceeding . . . to make such device a banned device." § 360f(a) (emphasis added).

The Court points to other statutory subsections which it believes require the FDA to ban a drug or device entirely, even where an outright ban risks more harm than other regulatory responses. See ante, at 135-136. But the cited provisions do no such thing. It is true, as the majority contends, that "the FDCA requires the FDA to place all devices" in "one of three classifications" and that Class III devices require "premarket approval." Ante, at 136. But it is not the case that the FDA must place cigarettes in Class III because tobacco itself "presents a potential unreasonable risk of illness or injury." 21 U. S. C. § 360c(a)(1)(C). In fact, Class III applies only where regulation cannot otherwise "provide reasonable assurance of . . . safety." §§ 360c(a) (1)(A), (B) (placing a device in Class I or Class II when regulation can provide that assurance). Thus, the statute plainly allows the FDA to consider the relative, overall "safety" of [176] a device in light of its regulatory alternatives, and where the FDA has chosen the least dangerous path, i. e., the safest path, then it can—and does—provide a "reasonable assurance" of "safety" within the meaning of the statute. A good football helmet provides a reasonable assurance of safety for the player even if the sport itself is still dangerous. And the safest regulatory choice by definition offers a "reasonable" assurance of safety in a world where the other alternatives are yet more dangerous.

In any event, it is not entirely clear from the statute's text that a Class III categorization would require the FDA affirmatively to withdraw from the market dangerous devices, such as cigarettes, which are already widely distributed. See, e. g., § 360f(a) (when a device presents an "unreasonable and substantial risk of illness or injury," the Secretary "may" make it "a banned device"); § 360h(a) (when a device "presents an unreasonable risk of substantial harm to the public health," the Secretary "may" require "notification"); § 360h(b) (when a defective device creates an "unreasonable risk" of harm, the Secretary "may" order "[r]epair, replacement, or refund"); cf. 2 O'Reilly § 18.08, at 18-29 (point of Class III "premarket approval" is to allow "careful scientific review" of each "truly new" device "before it is exposed" to users (emphasis added)).

Noting that the FDCA requires banning a "misbranded" drug, the majority also points to 21 U. S. C. § 352(j), which deems a drug or device "misbranded" if "it is dangerous to health when used" as "prescribed, recommended, or suggested in the labeling." See ante, at 135. In addition, the majority mentions § 352(f)(1), which calls a drug or device "misbranded" unless "its labeling bears . . . adequate directions for use" as "are necessary for the protection of users." Ibid. But this "misbranding" language is not determinative, for it permits the FDA to conclude that a drug or device is not "dangerous to health" and that it does have "adequate" [177] directions when regulated so as to render it as harmless as possible. And surely the agency can determine that a substance is comparatively "safe" (not "dangerous") whenever it would be less dangerous to make the product available (subject to regulatory requirements) than suddenly to withdraw it from the market. Any other interpretation risks substantial harm of the sort that my sleeping pill example illustrates. See supra, at 174-175. And nothing in the statute prevents the agency from adopting a view of "safety" that would avoid such harm. Indeed, the FDA already seems to have taken this position when permitting distribution of toxic drugs, such as poisons used for chemotherapy, that are dangerous for the user but are not deemed "dangerous to health" in the relevant sense. See 61 Fed. Reg. 44413 (1996).

The tobacco companies point to another statutory provision which says that if a device "would cause serious, adverse health consequences or death, the Secretary shall issue" a cease distribution order. 21 U. S. C. § 360h(e)(1) (emphasis added). But that word "shall" in this context cannot mean that the Secretary must resort to the recall remedy whenever a device would have serious, adverse health effects. Rather, that language must mean that the Secretary "shall issue" a cease distribution order in compliance with the section's procedural requirements if the Secretary chooses in her discretion to use that particular subsection's recall remedy. Otherwise, the subsection would trump and make meaningless the same section's provision of other lesser remedies such as simple "notice" (which the Secretary similarly can impose if, but only if, she finds that the device "presents an unreasonable risk of substantial harm to the public"). § 360h(a)(1). And reading the statute to compel the FDA to "recall" every dangerous device likewise would conflict with that same subsection's statement that the recall remedy "shall be in addition to [the other] remedies provided" in the statute. § 360h(e)(3) (emphasis added).

[178] The statute's language, then, permits the agency to choose remedies consistent with its basic purpose—the overall protection of public health.

The second reason the FDCA does not require the FDA to select the more dangerous remedy, see supra, at 175, is that, despite the majority's assertions to the contrary, the statute does not distinguish among the kinds of health effects that the agency may take into account when assessing safety. The Court insists that the statute only permits the agency to take into account the health risks and benefits of the "product itself " as used by individual consumers, ante, at 140, and, thus, that the FDA is prohibited from considering that a ban on smoking would lead many smokers to suffer severe withdrawal symptoms or to buy possibly stronger, more dangerous, black market cigarettes—considerations that the majority calls "the aggregate health effects of alternative administrative actions." Ibid. But the FDCA expressly permits the FDA to take account of comparative safety in precisely this manner. See, e. g., 21 U. S. C. § 360h(e)(2)(B)(i)(II) (no device recall if "risk of recal[l]" presents "a greater health risk than" no recall); § 360h(a) (notification "unless" notification "would present a greater danger" than "no such notification").

Moreover, one cannot distinguish in this context between a "specific" health risk incurred by an individual and an "aggregate" risk to a group. All relevant risk is, at bottom, risk to an individual; all relevant risk attaches to "the product itself"; and all relevant risk is "aggregate" in the sense that the agency aggregates health effects in order to determine risk to the individual consumer. If unregulated smoking will kill 4 individuals out of a typical group of 1,000 people, if regulated smoking will kill 1 out of 1,000, and if a smoking ban (because of the black market) will kill 2 out of 1,000; then these three possibilities mean that in each group four, one, and two individuals, on average, will die respectively. And the risk to each individual consumer is 4/1,000, [179] 1/1,000, and 2/1,000 respectively. A "specific" risk to an individual consumer and "aggregate" risks are two sides of the same coin; each calls attention to the same set of facts. While there may be a theoretical distinction between the risk of the product itself and the risk related to the presence or absence of an intervening voluntary act (e. g., the search for a replacement on the black market), the majority does not rely upon any such distinction, and the FDA's history of regulating "replacement" drugs such as methadone shows that it has long taken likely actual alternative consumer behavior into account.

I concede that, as a matter of logic, one could consider the FDA's "safety" evaluation to be different from its choice of remedies. But to read the statute to forbid the agency from taking account of the realities of consumer behavior either in assessing safety or in choosing a remedy could increase the risks of harm—doubling the risk of death to each "individual user" in my example above. Why would Congress insist that the FDA ignore such realities, even if the consequent harm would occur only unusually, say, where the FDA evaluates a product (a sleeping pill; a cigarette; a contact lens) that is already on the market, potentially habit forming, or popular? I can find no satisfactory answer to this question. And that, I imagine, is why the statute itself says nothing about any of the distinctions that the Court has tried to draw. See 21 U. S. C. § 360c(a)(2) (instructing FDA to determine the safety and effectiveness of a "device" in part by weighing "any probable benefit to health . . . against any probable risk of injury or illness . . ." (emphasis added)).

Third, experience counsels against an overly rigid interpretation of the FDCA that is divorced from the statute's overall health-protecting purposes. A different set of words, added to the FDCA in 1958 by the Delaney Amendment, provides that "no [food] additive shall be deemed to be safe if it is found [after appropriate tests] to induce cancer when ingested by man or animal." § 348(c)(3). The FDA [180] once interpreted this language as requiring it to ban any food additive, no matter how small the amount, that appeared in any food product if that additive was ever found to induce cancer in any animal, no matter how large a dose needed to induce the appearance of a single carcinogenic cell. See H. R. Rep. No. 95-658, p. 7 (1977) (discussing agency's view). The FDA believed that the statute's ban mandate was absolute and prevented it from establishing a level of "safe use" or even to judge whether "the benefits of continued use outweigh the risks involved." Id., at 5. This interpretation— which in principle could have required the ban of everything from herbal teas to mushrooms—actually led the FDA to ban saccharine, see 42 Fed. Reg. 19996 (1977), though this extremely controversial regulatory response never took effect because Congress enacted, and has continually renewed, a law postponing the ban. See Saccharin Study and Labeling Act, Pub. L. 95-203, § 3, 91 Stat. 1452; e. g., Pub. L. 102-142, Tit. VI, 105 Stat. 910.

The Court's interpretation of the statutory language before us risks Delaney-type consequences with even less linguistic reason. Even worse, the view the Court advances undermines the FDCA's overall health-protecting purpose by placing the FDA in the strange dilemma of either banning completely a potentially dangerous drug or device or doing nothing at all. Saying that I have misunderstood its conclusion, the majority maintains that the FDA "may clearly regulate many `dangerous' products without banning them." Ante, at 142. But it then adds that the FDA must ban— rather than otherwise regulate—a drug or device that "cannot be used safely for any therapeutic purpose." Ibid. If I misunderstand, it is only because this linchpin of the majority's conclusion remains unexplained. Why must a widely used but unsafe device be withdrawn from the market when that particular remedy threatens the health of many and is thus more dangerous than another regulatory response? It is, indeed, a perverse interpretation that reads the FDCA [181] to require the ban of a device that has no "safe" therapeutic purpose where a ban is the most dangerous remedial alternative.

In my view, where linguistically permissible, we should interpret the FDCA in light of Congress' overall desire to protect health. That purpose requires a flexible interpretation that both permits the FDA to take into account the realities of human behavior and allows it, in appropriate cases, to choose from its arsenal of statutory remedies. A statute so interpreted easily "fit[s]" this, and other, drug- and device-related health problems.

III

In the majority's view, laws enacted since 1965 require us to deny jurisdiction, whatever the FDCA might mean in their absence. But why? Do those laws contain language barring FDA jurisdiction? The majority must concede that they do not. Do they contain provisions that are inconsistent with the FDA's exercise of jurisdiction? With one exception, see infra, at 184-185, the majority points to no such provision. Do they somehow repeal the principles of law (discussed in Part II, supra ) that otherwise would lead to the conclusion that the FDA has jurisdiction in this area? The companies themselves deny making any such claim. See Tr. of Oral Arg. 27 (denying reliance on doctrine of "partial repeal"). Perhaps the later laws "shape" and "focus" what the 1938 Congress meant a generation earlier. Ante, at 143. But this Court has warned against using the views of a later Congress to construe a statute enacted many years before. See Pension Benefit Guaranty Corporation v. LTV Corp., 496 U. S. 633, 650 (1990) (later history is a "`hazardous basis for inferring the intent of an earlier' Congress" (quoting United States v. Price, 361 U. S. 304, 313 (1960))). And, while the majority suggests that the subsequent history "control[s] our construction" of the FDCA, see ante, at 143 (citation and internal quotation marks omitted), this Court [182] expressly has held that such subsequent views are not "controlling." Haynes v. United States, 390 U. S. 85, 87-88, n. 4 (1968); accord, Southwestern Cable Co., 392 U. S., at 170 (such views have "`very little, if any, significance' "); see also Sullivan v. Finkelstein, 496 U. S. 617, 632 (1990) (Scalia, J., concurring) ("Arguments based on subsequent legislative history . . . should not be taken seriously, not even in a footnote").

Regardless, the later statutes do not support the majority's conclusion. That is because, whatever individual Members of Congress after 1964 may have assumed about the FDA's jurisdiction, the laws they enacted did not embody any such "no jurisdiction" assumption. And one cannot automatically infer an antijurisdiction intent, as the majority does, for the later statutes are both (and similarly) consistent with quite a different congressional desire, namely, the intent to proceed without interfering with whatever authority the FDA otherwise may have possessed. See, e. g., Cigarette Labeling and Advertising—1965: Hearings on H. R. 2248 et al. before the House Committee on Interstate and Foreign Commerce, 89th Cong., 1st Sess., 19 (1965) (hereinafter 1965 Hearings) (statement of Rep. Fino that the proposed legislation would not "erode" agency authority). As I demonstrate below, the subsequent legislative history is critically ambivalent, for it can be read either as (a) "ratif[ying]" a no-jurisdiction assumption, see ante, at 158, or as (b) leaving the jurisdictional question just where Congress found it. And the fact that both inferences are "equally tenable," Pension Benefit Guaranty Corp., supra, at 650 (citation and internal quotation marks omitted); Johnson v. Transportation Agency, Santa Clara Cty., 480 U. S. 616, 672 (1987) (Scalia, J., dissenting), prevents the majority from drawing from the later statutes the firm, antijurisdiction implication that it needs.

Consider, for example, Congress' failure to provide the FDA with express authority to regulate tobacco—a circumstance [183] that the majority finds significant. See ante, at 144, 147-148, 155. But cf. Southwestern Cable Co., supra, at 170 (failed requests do not prove agency "did not already possess" authority). In fact, Congress both failed to grant express authority to the FDA when the FDA denied it had jurisdiction over tobacco and failed to take that authority expressly away when the agency later asserted jurisdiction. See, e. g., S. 1262, 104th Cong., 1st Sess., § 906 (1995) (failed bill seeking to amend FDCA to say that "[n]othing in this Act or any other Act shall provide the [FDA] with any authority to regulate in any manner tobacco or tobacco products"); see also H. R. 516, 105th Cong., 1st Sess., § 2 (1997) (similar); H. R. Res. 980, reprinted in 142 Cong. Rec. 5018 (1996) (Georgia legislators unsuccessfully requested that Congress "rescind any action giving the FDA authority" over tobacco); H. R. 2283, 104th Cong., 1st Sess. (1995) (failed bill "[t]o prohibit the [FDA] regulation of the sale or use of tobacco"); H. R. 2414, 104th Cong., 1st Sess., § 2(a) (1995) (similar). Consequently, the defeat of various different proposed jurisdictional changes proves nothing. This history shows only that Congress could not muster the votes necessary either to grant or to deny the FDA the relevant authority. It neither favors nor disfavors the majority's position.

The majority also mentions the speed with which Congress acted to take jurisdiction away from other agencies once they tried to assert it. See ante, at 145, 149-151. But such a congressional response again proves nothing. On the one hand, the speedy reply might suggest that Congress somehow resented agency assertions of jurisdiction in an area it desired to reserve for itself—a consideration that supports the majority. On the other hand, Congress' quick reaction with respect to other agencies' regulatory efforts contrasts dramatically with its failure to enact any responsive law (at any speed) after the FDA asserted jurisdiction over tobacco more than three years ago. And that contrast supports the opposite conclusion.

[184] In addition, at least one post-1938 statute reveals quite a different congressional intent than the majority infers. See note following 21 U. S. C. § 321 (1994 ed., Supp. III) (FDA Modernization Act of 1997) (law "shall [not] be construed to affect the question of whether the [FDA] has any authority to regulate any tobacco product," and "[s]uch authority, if any, shall be exercised under the [FDCA] as in effect on the day before the date of [this] enactment"). Consequently, it appears that the only interpretation that can reconcile all of the subsequent statutes is the inference that Congress did not intend, either explicitly or implicitly, for its later laws to answer the question of the scope of the FDA's jurisdictional authority. See 143 Cong. Rec. S8860 (Sept. 5, 1997) (the Modernization Act will "not interfere or substantially negatively affect any of the FDA tobacco authority").

The majority's historical perspective also appears to be shaped by language in the Federal Cigarette Labeling and Advertising Act (FCLAA), 79 Stat. 282, 15 U. S. C. § 1331 et seq. See ante, at 148-149. The FCLAA requires manufacturers to place on cigarette packages, etc., health warnings such as the following:

"SURGEON GENERAL'S WARNING: Smoking Causes Lung Cancer, Heart Disease, Emphysema, And May Complicate Pregnancy." 15 U. S. C. § 1333(a).

The FCLAA has an express pre-emption provision which says that "[n]o statement relating to smoking and health, other than the statement required by [this Act], shall be required on any cigarette package." § 1334(a). This preemption clause plainly prohibits the FDA from requiring on "any cigarette package" any other "statement relating to smoking and health," but no one contends that the FDA has failed to abide by this prohibition. See, e. g., 61 Fed. Reg. 44399 (1996) (describing the other regulatory prescriptions). Rather, the question is whether the FCLAA's pre-emption [185] provision does more. Does it forbid the FDA to regulate at all?

This Court has already answered that question expressly and in the negative. See Cipollone v. Liggett Group, Inc., 505 U. S. 504 (1992). Cipollone held that the FCLAA's preemption provision does not bar state or federal regulation outside the provision's literal scope. Id., at 518. And it described the pre-emption provision as "merely prohibit[ing] state and federal rulemaking bodies from mandating particular cautionary statements on cigarette labels . . . ." Ibid.

This negative answer is fully consistent with Congress' intentions in regard to the pre-emption language. When Congress enacted the FCLAA, it focused upon the regulatory efforts of the Federal Trade Commission (FTC), not the FDA. See 1965 Hearings 1-2. And the Public Health Cigarette Smoking Act of 1969, Pub. L. 91-222, § 7(c), 84 Stat. 89, expressly amended the FCLAA to provide that "[n]othing in this Act shall be construed to affirm or deny the [FTC's] holding that it has the authority to issue trade regulation rules" for tobacco. See also H. R. Conf. Rep. No. 91-897, p. 7 (1970) (statement of House Managers) (we have "no intention to resolve the question as to whether" the FTC could regulate tobacco in a different way); see also 116 Cong. Rec. 7921 (1970) (statement of Rep. Satterfield) (same). Why would one read the FCLAA's pre-emption clause—a provision that Congress intended to limit even in respect to the agency directly at issue—so broadly that it would bar a different agency from engaging in any other cigarette regulation at all? The answer is that the Court need not, and should not, do so. And, inasmuch as the Court already has declined to view the FCLAA as pre-empting the entire field of tobacco regulation, I cannot accept that that same law bars the FDA's regulatory efforts here.

When the FCLAA's narrow pre-emption provision is set aside, the majority's conclusion that Congress clearly intended for its tobacco-related statutes to be the exclusive [186] "response" to "the problem of tobacco and health," ante, at 157, is based on legislative silence. Notwithstanding the views voiced by various legislators, Congress itself has addressed expressly the issue of the FDA's tobacco-related authority only once—and, as I have said, its statement was that the statute was not to "be construed to affect the question of whether the [FDA] has any authority to regulate any tobacco product." Note following 21 U. S. C. § 321 (1994 ed., Supp. III). The proper inference to be drawn from all of the post-1965 statutes, then, is one that interprets Congress' general legislative silence consistently with this statement.

IV

I now turn to the final historical fact that the majority views as a factor in its interpretation of the subsequent legislative history: the FDA's former denials of its tobaccorelated authority.

Until the early 1990's, the FDA expressly maintained that the 1938 statute did not give it the power that it now seeks to assert. It then changed its mind. The majority agrees with me that the FDA's change of positions does not make a significant legal difference. See ante, at 156-157; see also Chevron, 467 U. S., at 863 ("An initial agency interpretation is not instantly carved in stone"); accord, Smiley v. Citibank (South Dakota), N. A., 517 U. S. 735, 742 (1996) ("[C]hange is not invalidating"). Nevertheless, it labels those denials "important context" for drawing an inference about Congress' intent. Ante, at 157. In my view, the FDA's change of policy, like the subsequent statutes themselves, does nothing to advance the majority's position.

When it denied jurisdiction to regulate cigarettes, the FDA consistently stated why that was so. In 1963, for example, FDA administrators wrote that cigarettes did not satisfy the relevant FDCA definitions—in particular, the "intent" requirement—because cigarette makers did not sell their product with accompanying "therapeutic claims." [187] Letter to Directors of Bureaus, Divisions and Directors of Districts from FDA Bureau of Enforcement (May 24, 1963), in Public Health Cigarette Amendments of 1971: Hearings on S. 1454 before the Consumer Subcommittee of the Senate Committee on Commerce, 92d Cong., 2d Sess., 240 (1972) (hereinafter FDA Enforcement Letter). And subsequent FDA Commissioners made roughly the same assertion. One pointed to the fact that the manufacturers only "recommended" cigarettes "for smoking pleasure." Two others reiterated the evidentiary need for "health claims." Yet another stressed the importance of proving "intent," adding that "[w]e have not had sufficient evidence" of "intent with regard to nicotine." See, respectively, id., at 239 (Comm'r Edwards); Letter of Dec. 5, 1977, App. 47 (Comm'r Kennedy); 1965 Hearings 193 (Comm'r Rankin); 1994 Hearings 28 (Comm'r Kessler). Tobacco company counsel also testified that the FDA lacked jurisdiction because jurisdiction "depends on . . . intended use," which in turn "depends, in general, on the claims and representations made by the manufacturer." Health Consequences of Smoking: Nicotine Addiction, Hearing before the Subcommittee on Health and the Environment of the House Committee on Energy and Commerce, 100th Cong., 2d Sess., 288 (1988) (testimony of Richard Cooper) (emphasis added).

Other agency statements occasionally referred to additional problems. Commissioner Kessler, for example, said that the "enormous social consequences" flowing from a decision to regulate tobacco counseled in favor of obtaining specific congressional "guidance." 1994 Hearings 69; see also ante, at 153 (quoting statement of Health and Human Services Secretary Brandt to the effect that Congress wanted to make the relevant jurisdictional decision). But a fair reading of the FDA's denials suggests that the overwhelming problem was one of proving the requisite manufacturer intent. See Action on Smoking and Health v. Harris, 655 F. 2d 236, 238-239 (CADC 1980) (FDA "comments" reveal its "understanding" [188] that "the crux of FDA jurisdiction over drugs lay in manufacturers' representations as revelatory of their intent").

What changed? For one thing, the FDA obtained evidence sufficient to prove the necessary "intent" despite the absence of specific "claims." See supra, at 172-174. This evidence, which first became available in the early 1990's, permitted the agency to demonstrate that the tobacco companies knew nicotine achieved appetite-suppressing, mood-stabilizing, and habituating effects through chemical (not psychological) means, even at a time when the companies were publicly denying such knowledge.

Moreover, scientific evidence of adverse health effects mounted, until, in the late 1980's, a consensus on the seriousness of the matter became firm. That is not to say that concern about smoking's adverse health effects is a new phenomenon. See, e. g., Higginson, A New Counterblast, in Out-door Papers 179, 194 (1863) (characterizing tobacco as "`a narcotic poison of the most active class' "). It is to say, however, that convincing epidemiological evidence began to appear mid-20th century; that the first Surgeon General's Report documenting the adverse health effects appeared in 1964; and that the Surgeon General's Report establishing nicotine's addictive effects appeared in 1988. At each stage, the health conclusions were the subject of controversy, diminishing somewhat over time, until recently—and only recently—has it become clear that there is a wide consensus about the health problem. See 61 Fed. Reg. 44701-44706 (1996).

Finally, administration policy changed. Earlier administrations may have hesitated to assert jurisdiction for the reasons prior Commissioners expressed. See supra, at 186-187 and this page. Commissioners of the current administration simply took a different regulatory attitude.

Nothing in the law prevents the FDA from changing its policy for such reasons. By the mid-1990's, the evidence [189] needed to prove objective intent—even without an express claim—had been found. The emerging scientific consensus about tobacco's adverse, chemically induced, health effects may have convinced the agency that it should spend its resources on this important regulatory effort. As for the change of administrations, I agree with then-Justice Rehnquist's statement in a different case, where he wrote:

"The agency's changed view . . . seems to be related to the election of a new President of a different political party. It is readily apparent that the responsible members of one administration may consider public resistance and uncertainties to be more important than do their counterparts in a previous administration. A change in administration brought about by the people casting their votes is a perfectly reasonable basis for an executive agency's reappraisal of the costs and benefits of its programs and regulations. As long as the agency remains within the bounds established by Congress, it is entitled to assess administrative records and evaluate priorities in light of the philosophy of the administration." Motor Vehicle Mfrs. Assn. of United States, Inc. v. State Farm Mut. Automobile Ins. Co., 463 U. S. 29, 59 (1983) (concurring in part and dissenting in part).

V

One might nonetheless claim that, even if my interpretation of the FDCA and later statutes gets the words right, it lacks a sense of their "music." See Helvering v. Gregory, 69 F. 2d 809, 810-811 (CA2 1934) (L. Hand, J.) ("[T]he meaning of a [statute] may be more than that of the separate words, as a melody is more than the notes . . .").Such a claim might rest on either of two grounds.

First, one might claim that, despite the FDA's legal right to change its mind, its original statements played a critical part in the enactment of the later statutes and now should play a critical part in their interpretation. But the FDA's [190] traditional view was largely premised on a perceived inability to prove the necessary statutory "intent" requirement. See, e. g., FDA Enforcement Letter 240 ("The statutory basis for the exclusion of tobacco products from FDA's jurisdiction is the fact that tobacco marketed for chewing or smoking without accompanying therapeutic claims, does not meet the definitions . . . for food, drug, device or cosmetic"). The statement, "we cannot assert jurisdiction over substance X unless it is treated as a food," would not bar jurisdiction if the agency later establishes that substance X is, and is intended to be, eaten. The FDA's denials of tobacco-related authority sufficiently resemble this kind of statement that they should not make the critical interpretive difference.

Second, one might claim that courts, when interpreting statutes, should assume in close cases that a decision with "enormous social consequences," 1994 Hearings 69, should be made by democratically elected Members of Congress rather than by unelected agency administrators. Cf. Kent v. Dulles, 357 U. S. 116, 129 (1958) (assuming Congress did not want to delegate the power to make rules interfering with exercise of basic human liberties). If there is such a background canon of interpretation, however, I do not believe it controls the outcome here.

Insofar as the decision to regulate tobacco reflects the policy of an administration, it is a decision for which that administration, and those politically elected officials who support it, must (and will) take responsibility. And the very importance of the decision taken here, as well as its attendant publicity, means that the public is likely to be aware of it and to hold those officials politically accountable. Presidents, just like Members of Congress, are elected by the public. Indeed, the President and Vice President are the only public officials whom the entire Nation elects. I do not believe that an administrative agency decision of this magnitude—one that is important, conspicuous, and controversial—can escape the kind of public scrutiny that is essential in any democracy. [191] And such a review will take place whether it is the Congress or the Executive Branch that makes the relevant decision.

According to the FDA, only 2.5% of smokers successfully stop smoking each year, even though 70% say they want to quit and 34% actually make an attempt to do so. See 61 Fed. Reg. 44704 (1996) (citing Centers for Disease Control and Prevention, Cigarette Smoking Among Adults—United States, 1993; 43 Morbidity and Mortality Weekly Report 929 (Dec. 23, 1994)). The fact that only a handful of those who try to quit smoking actually succeed illustrates a certain reality—the reality that the nicotine in cigarettes creates a powerful physiological addiction flowing from chemically induced changes in the brain. The FDA has found that the makers of cigarettes "intend" these physical effects. Hence, nicotine is a "drug"; the cigarette that delivers nicotine to the body is a "device"; and the FDCA's language, read in light of its basic purpose, permits the FDA to assert the disease-preventing jurisdiction that the agency now claims.

The majority finds that cigarettes are so dangerous that the FDCA would require them to be banned (a result the majority believes Congress would not have desired); thus, it concludes that the FDA has no tobacco-related authority. I disagree that the statute would require a cigarette ban. But even if I am wrong about the ban, the statute would restrict only the agency's choice of remedies, not its jurisdiction.

The majority also believes that subsequently enacted statutes deprive the FDA of jurisdiction. But the later laws say next to nothing about the FDA's tobacco-related authority. Previous FDA disclaimers of jurisdiction may have helped to form the legislative atmosphere out of which Congress' own tobacco-specific statutes emerged. But a legislative atmosphere is not a law, unless it is embodied in a statutory word or phrase. And the relevant words and phrases here reveal [192] nothing more than an intent not to change the jurisdictional status quo.

The upshot is that the Court today holds that a regulatory statute aimed at unsafe drugs and devices does not authorize regulation of a drug (nicotine) and a device (a cigarette) that the Court itself finds unsafe. Far more than most, this particular drug and device risks the life-threatening harms that administrative regulation seeks to rectify. The majority's conclusion is counterintuitive. And, for the reasons set forth, I believe that the law does not require it.

Consequently, I dissent.
