Sixteen years ago, this Court held that Congress’ power to regulate interstate commerce authorized it “to prohibit the local cultivation and use of marijuana.” Gonzales v. Raich, 545 U. S. 1, 5 (2005). The reason, the Court explained, was that Congress had “enacted comprehensive legislation to regulate the interstate market in a fungible commodity” and that “exemption[s]” for local use could undermine this “comprehensive” regime. Id., at 22–29. The Court stressed that Congress had decided “to prohibit entirely the possession or use of [marijuana]” and had “designate[d] marijuana as contraband for any purpose.” Id., at 24–27 (first emphasis added). Prohibiting any intrastate use was thus, according to the Court, “‘necessary and proper’” to avoid a “gaping hole” in Congress’ “closed regulatory system.” Id., at 13, 22 (citing U. S. Const., Art. I, §8).
Whatever the merits of Raich when it was decided, federal policies of the past 16 years have greatly undermined its reasoning. Once comprehensive, the Federal Government’s current approach is a half-in, half-out regime that simultaneously tolerates and forbids local use of marijuana. This contradictory and unstable state of affairs strains basic principles of federalism and conceals traps for the unwary
Thomas notes that the federal government outlaws marijuana even though 36 states have legalized it for medical use and 18 allow recreational use.
Yet, as petitioners recently discovered, legality understate law and the absence of federal criminal enforcement do not ensure equal treatment. At issue here is a provision of the Tax Code that allows most businesses to calculate their taxable income by subtracting from their gross revenue the cost of goods sold and other ordinary and necessary business expenses, such as rent and employee salaries. See 26 U. S. C. §162(a); 26 CFR. 1.61–3(a) (2020). But because of a public-policy provision in the Tax Code, companies that deal in controlled substances prohibited by federal law may subtract only the cost of goods sold, not the other ordinary and necessary business expenses. See 26 U. S. C. §280E. Under this rule, a business that is still in the red after it pays its workers and keeps the lights on might nonetheless owe substantial federal income tax.

This disjuncture between the Government’s recent laissez-faire policies on marijuana and the actual operation of specific laws is not limited to the tax context. Many marijuana-related businesses operate entirely in cash because federal law prohibits certain financial institutions from knowingly accepting deposits from or providing other bank services to businesses that violate federal law. Black & Galeazzi, Cannabis Banking: Proceed With Caution, American Bar Assn., Feb. 6, 2020. Cash-based operations are understandably enticing to burglars and robbers. But, if marijuana-related businesses, in recognition of this, hire armed guards for protection, the owners and the guards might run afoul of a federal law that imposes harsh penalties for using a firearm in furtherance of a “drug trafficking crime.” 18 U. S. C. §924(c)(1)(A). A marijuana user similarly can find himself a federal felon if he just possesses a firearm. §922(g)(3). Or petitioners and similar businesses may find themselves on the wrong side of a civil suit under the Racketeer Influenced and Corrupt Organizations Act. See, e.g., Safe Streets Alliance v. Hickenlooper, 859 F. 3d 865, 876– 877 (CA10 2017) (permitting such a suit to proceed).
