accepted safety for use... under medical supervision," 21 U. S. C. §812(b)(1), by itself precludes any consideration of individualized exceptions, and that the Act's "closed" regulatory system, which prohibits all use of controlled substances except as the Act itself authorizes, see Gonzales v. Raich, 545 U. S. ___, ___, cannot function properly if subjected to judicial exemptions. Pp. 8–16.
(a) RFRA and its strict scrutiny test contemplate an inquiry more focused than the Government's categorical approach. RFRA requires the Government to demonstrate that the compelling interest test is satisfied through application of the challenged law "to the person"—the particular claimant whose sincere exercise of religion is being substantially burdened. 42 U. S. C. §2000bb–1(b). Section 2000bb(b)(1) expressly adopted the compelling interest test of Sherbert v. Verner, 374 U. S. 398, and Wisconsin v. Yoder, 406 U. S. 205. There, the Court looked beyond broadly formulated interests justifying the general applicability of government mandates, scrutinized the asserted harms, and granted specific exemptions to particular religious claimants. Id., at 213, 221, 236; Sherbert, supra, at 410. Outside the Free Exercise area as well, the Court has noted that "[c]ontext matters" in applying the compelling interest test, Grutter v. Bollinger, 539 U. S. 306, 327, and has emphasized that strict scrutiny's fundamental purpose is to take "relevant differences" into account, Adarand Constructors, Inc. v. Peña, 515 U. S. 200, 228. Pp. 9–10.
(b) Under RFRA's more focused inquiry, the Government's mere invocation of the general characteristics of Schedule I substances cannot carry the day. Although Schedule I substances such as DMT are exceptionally dangerous, see, e.g., Touby v. United States, 500 U. S. 160, 162, there is no indication that Congress, in classifying DMT, considered the harms posed by the particular use at issue. That question was litigated below. Before the District Court found that the Government had not carried its burden of showing a compelling interest in preventing such harm, the court noted that it could not ignore the congressional classification and findings. But Congress' determination that DMT should be listed under Schedule I simply does not provide a categorical answer that relieves the Government of the obligation to shoulder its RFRA burden. The Controlled Substances Act's authorization to the Attorney General to "waive the requirement for registration of certain manufacturers, distributors, or dispensers if he finds it consistent with the public health and safety," 21 U. S. C. §822(d), reinforces that Congress' findings with respect to Schedule I substances should not carry the determinative weight, for RFRA purposes, that the Government would ascribe to them. Indeed, despite the fact that everything the Government says about the DMT in hoasca applies in equal measure to the
