Is psilocybin legal in the United States?
No. Psilocybin remains a Schedule I controlled substance under the federal Controlled Substances Act as of 30 August 2026. It has not been approved by the FDA and has not been rescheduled by the DEA. Two states, Oregon and Colorado, run legal supervised-access programs under their own law, and an adult aged 21 or over can take psilocybin lawfully at a licensed site in either. That removes the state charge in those two states. It does not remove federal exposure, which applies everywhere in the country regardless of state law.
