The Controlled Substances Act was enacted as Title II of Public Law 91-513 on 27 October 1970 and establishes five schedules of controlled substances (21 U.S.C. § 812). Placement depends on findings about potential for abuse, accepted medical use and safety under medical supervision.
Psilocybin and psilocyn were in Schedule I from the statute’s original list, and the current federal regulation still lists both there (eCFR, 21 CFR 1308.11). Schedule I is for substances with a high potential for abuse, no currently accepted medical use in treatment in the United States and a lack of accepted safety under medical supervision (21 U.S.C. § 812).
States can pass their own laws, and Oregon and Colorado have created licensed psilocybin programs. Those state laws do not change the federal listing, so activities that are lawful under state rules can still be federal offences. Canada’s equivalent statute is the Controlled Drugs and Substances Act. Not legal advice.
