Is psilocybin legal in Colorado? What the Natural Medicine Health Act allows in 2026

In November 2022, Colorado voters passed Proposition 122, the Natural Medicine Health Act of 2022. It did two things. It decriminalized personal possession, growing, sharing and use of certain natural medicines for adults 21 and over. It also directed the state to build a regulated program where licensed facilitators provide those medicines in supervised settings.

In May 2023, Governor Jared Polis signed SB23-290, which filled in how that regulated program would work. Both state agencies began accepting license applications in December 2024: DORA for facilitators, and the Department of Revenue for healing centers and other businesses.

The program currently centers on psilocybin and psilocin, the active compounds in psilocybin mushrooms. Proposition 122 also named DMT, ibogaine and mescaline (not including peyote). These could be added to the regulated program from 2026 if the Natural Medicine Advisory Board recommends it. This article covers psilocybin only.

Personal use. According to the Natural Medicine Division, an adult 21 or older in Colorado may:

• grow psilocybin mushrooms in a 12 by 12 foot space that is locked to anyone under 21
• possess psilocybin with no personal possession limit
• share it with other adults 21 and older in contexts such as counseling, spiritual guidance, community-based use or supported use, as long as nobody pays for the mushrooms themselves

Personal use comes with clear limits. You cannot sell natural medicine, and you cannot use it openly in public. The law allows payment only for genuine harm reduction or support services provided alongside sharing, never for the medicine.

Regulated services. This is the licensed system, and it is where guided retreats like Maureen Lennon-Schafer's sit. A licensed facilitator provides the service, normally at a licensed healing center, using psilocybin from a licensed cultivator or manufacturer. Wherever a regulated session happens, the psilocybin must come from a licensed natural medicine business.

• DORA (Department of Regulatory Agencies) licenses and disciplines facilitators. Its Office of Natural Medicine Licensure sets the rules for screening, preparation, sessions, integration and advertising. You can check a facilitator through DORA's license lookup tool.
• The Department of Revenue's Natural Medicine Division licenses healing centers, cultivations, product manufacturers, testing facilities, and their owners and staff. It also publishes a healing center directory and a map.

As of October 9, 2026, the Division reported 11 standard and 35 micro healing center licenses approved.

Colorado's facilitator rules (4 CCR 755-1) are detailed. Some of the main points:

• Age. A participant must be 21 or older, and the facilitator must check this before services begin.
• Screening. The facilitator must use a safety screening tool that reflects generally accepted standards of practice. If it finds risk factors, the facilitator may only proceed after a referral, medical clearance, or a consultation and risk review with the participant's own provider.
• Preparation. For doses above 2 mg of psilocin, a preparation session must take place at least 24 hours and no more than 60 days before the first session.
• Informed consent. The participant must be told about risks, the range of possible effects, and their right to end services at any time.
• Session length. For doses between 10 and 50 mg of total psilocin, the session lasts at least five hours and continues until the participant shows no obvious adverse effects.
• Groups. At those doses, there can be no more than four participants per facilitator.
• Transportation. A signed plan for getting home after the session is required.
• Integration. The facilitator reviews the session with the participant and recommends follow-up care or referrals where appropriate. The first integration session cannot be billed separately.

DORA issues more than one license type. A Facilitator may work independently with participants whose screening shows no risk factors that call for medical or behavioral health involvement. A Clinical Facilitator also holds a Colorado license in a field such as psychology, clinical social work, counseling or medicine. They may provide natural medicine services within the scope of that other license. Both must complete an approved training program of at least 150 hours, and both must keep up Basic Life Support certification.

• Selling psilocybin, outside the licensed business system, is prohibited.
• Use under 21 is not covered by the law.
• Public use is not allowed.
• Federal law. Psilocybin remains a Schedule I controlled substance under federal law. Colorado's law does not change that.
• Other states. Colorado's rules apply only in Colorado. Do not take psilocybin out of the state.

On New Jersey specifically: psilocybin services are not offered there. In January 2026 New Jersey enacted a law creating a state-funded psilocybin therapy pilot program, but it does not open public access. Halcyon's New Jersey house does not offer psilocybin.

If you are considering a guided experience, read our guide to psilocybin in Colorado. See what a small guided retreat looks like on our Boulder retreat page, and read the safety page before you decide anything.

Halcyon does not provide medical services and does not diagnose or treat any condition. Clinical services are provided by licensed professionals through our partner, Presence of Mind Therapy.
