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.
Implementation has continued through mid-2026. On 14 July 2026, the FDA issued final guidance on clinical investigations of psychedelic drugs, detailing expected trial populations and safety assessments, and opened registration for a 14 September public hearing on supervised psychedelic therapy. The VA and HHS also signed a memorandum of understanding to collaborate on psychedelic research and the potential rollout of any FDA-approved treatments to veterans. None of these steps reschedules psilocybin; a separate petition (Dr. Sunil Aggarwal's) to move it from Schedule I to Schedule II remains stalled at the DEA.
