Is psilocybin legal in Colorado? How does regulated access work?
Under Colorado state law, yes, for adults 21 and older. Under federal law, no. Colorado's Natural Medicine Health Act decriminalizes personal use of psilocybin and also created licensed healing centers, where trained facilitators supervise sessions on site. Selling psilocybin retail is still prohibited, and federal law still classifies psilocybin as Schedule I.
Colorado is one of two states with a licensed adult psilocybin program. This page covers what the law allows, how the healing center program works, and where federal law still applies. It is general information about the law, not legal advice, and it is reviewed at least quarterly because the rules are still being implemented.
What Colorado law allows
Voters approved Proposition 122, the Natural Medicine Health Act, in November 2022, making Colorado the second state to decriminalize personal use of psilocybin and other natural psychedelics for adults 21 and older (Denver Health). Two separate things came out of that law:
1. Personal use (decriminalized)
An adult 21 or older may grow psilocybin mushrooms in a 12-foot by 12-foot space that is locked to anyone under 21, may possess them with no personal possession limit, and may share them with other adults 21 and older. No payment is allowed for sharing, except alongside concurrent harm reduction services (Colorado Natural Medicine Division FAQ). Commercial retail sales remain prohibited, so there is no dispensary model like cannabis (Stateline).
2. Licensed healing centers (regulated)
A healing center is a licensed facility where a licensed facilitator provides and supervises natural medicine services for a participant (Colorado Natural Medicine Division). The state's first healing center license was issued in March 2025 (Rocky Mountain PBS).
| Topic | How the program works |
|---|---|
| Age | 21 and older |
| Who provides services | Licensed facilitators, with different license levels based on credentials; some are licensed mental health professionals |
| Screening | Participant and facilitator meet first to decide whether a session is appropriate |
| Where | On site at a licensed healing center, with the facilitator present; no take-home psilocybin |
| Exception | Narrow in-home option for end-of-life care, with strict protocols |
| Who regulates | Colorado Department of Regulatory Agencies (facilitator training and credentials) and Department of Revenue (business licensing) |
(Program rules per Rocky Mountain PBS and Stateline.) Local governments can also have their own rules, so check the city or county where you live.
What federal law says
Psilocybin remains a Schedule I controlled substance under federal law, and Colorado's law does not change that. In 2026, the federal government started moving to speed review of psychedelic drugs: an April 18, 2026 executive order directed the FDA to prioritize drugs with Breakthrough Therapy designation, and Colorado passed Senate Bill 26-31 on April 20, 2026, so that state law follows if the DEA reschedules an FDA-approved drug (Colorado Newsline). Neither step has made psilocybin federally legal today.
What this does not mean
- It does not mean you can buy psilocybin in a store. Retail sales are prohibited.
- It does not mean state law protects you from federal enforcement.
- It does not mean anyone under 21 is covered.
- It does not mean a healing center or a guide can promise a particular outcome.
