Syllabus
forcement difficulties that attend distinguishing between marijuana cultivated locally and marijuana grown elsewhere, 21 U. S. C. §801(5), and concerns about diversion into illicit channels, the Court has no difficulty concluding that Congress had a rational basis for believing that failure to regulate the intrastate manufacture and possession of marijuana would leave a gaping hole in the CSA. Pp. 15–22.
(c) Respondents’ heavy reliance on Lopez and Morrison overlooks the larger context of modern-era Commerce Clause jurisprudence preserved by those cases, while also reading those cases far too broadly. The statutory challenges at issue there were markedly different from the challenge here. Respondents ask the Court to excise individual applications of a concededly valid comprehensive statutory scheme. In contrast, in both Lopez and Morrison, the parties asserted that a particular statute or provision fell outside Congress’ commerce power in its entirety. This distinction is pivotal for the Court has often reiterated that “[w]here the class of activities is regulated and that class is within the reach of federal power, the courts have no power ‘to excise, as trivial, individual instances’ of the class.” Perez, 402 U. S., at 154. Moreover, the Court emphasized that the laws at issue in Lopez and Morrison had nothing to do with “commerce” or any sort of economic enterprise. See Lopez, 514 U. S., at 561; Morrison, 529 U. S., at 610. In contrast, the CSA regulates quintessentially economic activities: the production, distribution, and consumption of commodities for which there is an established, and lucrative, interstate market. Prohibiting the intrastate possession or manufacture of an article of commerce is a rational means of regulating commerce in that product. The Ninth Circuit cast doubt on the CSA’s constitutionality by isolating a distinct class of activities that it held to be beyond the reach of federal power: the intrastate, noncommercial cultivation, possession, and use of marijuana for personal medical purposes on the advice of a physician and in accordance with state law. However, Congress clearly acted rationally in determining that this subdivided class of activities is an essential part of the larger regulatory scheme. The case comes down to the claim that a locally cultivated product that is used domestically rather than sold on the open market is not subject to federal regulation. Given the CSA’s findings and the undisputed magnitude of the commercial market for marijuana, Wickard and its progeny foreclose that claim. Pp. 23–33.
