Legal Status

Psilocybin and psilocin are Schedule I controlled substances under the federal Controlled Substances Act of 1970, meaning federal authorities classify them as having no accepted medical use and a high potential for abuse. Both claims are at odds with the clinical literature; the scheduling has not caught up.

Federal law applies in every state, on federal property, and in interstate transport. A state can decide not to enforce possession or cultivation under its own laws — as Oregon and Colorado have — but federal agencies (DEA, FBI, U.S. Postal Inspectors) retain jurisdiction. In practice, federal prosecutions of small-scale personal use have been rare; federal enforcement focuses on trafficking, interstate commerce, and activity on federal land.

Spores themselves — which contain no psilocybin — occupy a narrow federal gap and are legal to possess federally for microscopy purposes, though a handful of states (CA, GA, ID) specifically criminalize them.

On 18 April 2026, the President signed an executive order titled Accelerating Medical Treatments for Serious Mental Illness, directing the FDA to prioritize psychedelic review, instructing the DEA to reduce research barriers, and allocating $50M in ARPA-H match funding for state psychedelic research. The order does not reschedule psilocybin, but it signals expansion of Right-to-Try pathways to Schedule I substances. On 24 April 2026, the FDA awarded Commissioner's National Priority Vouchers to Compass Pathways' COMP360 (treatment-resistant depression) and Usona Institute's psilocybin (major depressive disorder), the first concrete federal actions implementing the order.

Psilocybin and psilocin are Schedule III controlled substances under Canada’s Controlled Drugs and Substances Act (CDSA). Unauthorized possession, cultivation, production, and sale remain criminal offences nationwide.

On 5 January 2022, Health Canada amended the Food and Drug Regulations to make psilocybin (and MDMA) once again accessible through the Special Access Program (SAP), a pathway that had been closed since 2013. Under the SAP, physicians may request authorization for a specific patient with a serious or life-threatening condition where conventional treatments have failed or are unsuitable — predominantly end-of-life distress in terminal cancer patients and treatment-resistant depression.

A class exemption under section 56(1) of the CDSA covers the supply chain — practitioners, pharmacists, hospitals, and licensed dealers handling psilocybin tied to an SAP authorization — removing the need for an individual exemption at each link. A separate class exemption authorizes at-home administration of psilocybin and MDMA by participants in approved clinical trials.

Bill C-5 (2022) removed mandatory minimums for several CDSA offences and encouraged prosecutorial diversion for simple possession. It is not psilocybin-specific but lowered the floor for personal-possession prosecutions across the schedule.
