Is Psilocybin Legal in Colorado? State Law, Federal Status, and Key Limits
Psilocybin is decriminalized for adults 21+ in Colorado for personal use and possession, with licensed healing centers offering supervised sessions. Retail sales remain illegal, and federal law still classifies psilocybin as Schedule I.
Is Psilocybin Legal in Colorado? The Plain-English Answer
No, psilocybin is not "legal" in Colorado in the sense of being fully permitted or available for retail sale. However, under the Natural Medicine Health Act (Proposition 122, 2022), Colorado has decriminalized personal use, possession, and gifting of psilocybin mushrooms for adults 21 and older. This means that, under state law, adults are not subject to criminal penalties for possessing or personally using psilocybin mushrooms, but psilocybin remains illegal under U.S. federal law as a Schedule I controlled substance (per the Controlled Substances Act). Retail sale and unsupervised distribution are not permitted. Licensed healing centers may provide psilocybin sessions in a regulated, facilitator-supervised setting. This summary is for general informational purposes only and does not constitute legal advice.
Colorado's Psilocybin Law: Decriminalization and the Therapeutic Program
Colorado voters approved Proposition 122 in November 2022, enacting the Natural Medicine Health Act. This law made several important changes:
- Decriminalization for adults 21+: Personal use, possession, and gifting (but not sale) of psilocybin, psilocin, DMT (dimethyltryptamine), ibogaine, and mescaline (excluding peyote) are decriminalized for adults age 21 and older.
- Licensed healing centers: The law created a framework for state-licensed healing centers, where trained facilitators can administer psilocybin in supervised sessions. The Division of Professions and Occupations oversees licensing and facilitator standards.
- Retail sales prohibited: Retail sale, commercial distribution, and unsupervised public use of psilocybin are not allowed. Psilocybin-containing edibles and gummies are not a separate retail category and are not available for over-the-counter purchase.
- Future expansion: DMT, mescaline, and ibogaine are scheduled for review by an advisory board in 2026 for possible inclusion in the therapeutic program.
- Peyote exclusion: Peyote is explicitly excluded from decriminalization, respecting Native American Church (NAC) concerns.

Federal Law: Psilocybin Remains Schedule I
Despite Colorado's state-level reforms, psilocybin remains a Schedule I controlled substance under U.S. federal law. This means that, according to the federal government:
- Psilocybin has "no currently accepted medical use" and a "high potential for abuse" (Controlled Substances Act).
- Possession, distribution, or manufacture of psilocybin is a federal crime, except for approved research or very limited religious exemptions.
- No psilocybin formulation has been approved by the U.S. Food and Drug Administration (FDA) for medical use as of now.
Federal law applies everywhere in the United States, including Colorado. While federal enforcement against individual users in states with decriminalization is rare, the legal risk remains. For more context, see our briefing feed and research landscape.

Therapeutic Use: Healing Centers and Facilitator Supervision
Colorado's therapeutic psilocybin program is unique in the United States, following Oregon's earlier model. Key features include:
- Licensed healing centers: Facilities licensed by the state to provide psilocybin services in a controlled, supervised setting.
- Facilitator training and oversight: All sessions must be supervised by state-licensed facilitators, who complete approved training and adhere to professional standards.
- No take-home doses: Psilocybin must be consumed on-site during a supervised session; there is no prescription or take-home option.
- Program rollout: Licensing of healing centers began in 2024–2025, with oversight by the Colorado Division of Professions and Occupations.

Frequently Asked Questions
Can I buy psilocybin mushrooms at a dispensary in Colorado?
No. Retail sale of psilocybin mushrooms is not permitted anywhere in Colorado. The only legal pathway for access is through licensed healing centers, where use is supervised and not for take-home or resale.
Can I grow my own psilocybin mushrooms?
Personal cultivation for personal use by adults 21+ is decriminalized under state law, but sale or large-scale distribution is not allowed. Federal law still prohibits any cultivation.
What about other psychedelics?
Psilocin, DMT, ibogaine, and mescaline (not peyote) are also decriminalized for adults 21+ in Colorado. MDMA and LSD remain illegal under both state and federal law.
Could federal law enforcement still prosecute me?
Yes, in theory. Federal law supersedes state law, and psilocybin remains a Schedule I substance nationwide. While enforcement against individual users is rare, risks remain for larger-scale activities or those attracting federal attention.
