Who this is for: Individuals considering accessing natural medicine services in Colorado, out-of-state visitors evaluating Colorado as an option, and anyone trying to understand how Colorado’s program differs from Oregon’s and what the personal use decriminalization component means in practice.

The short answer

Colorado voters approved Proposition 122, the Natural Medicine Health Act, in November 2022, making Colorado the second state to create a legal framework for supervised psilocybin access. The program has two distinct components: a personal use decriminalization provision that took effect immediately, and a licensed healing center program that began accepting license applications in December 2024, with the first regulated session conducted in June 2025. Adults 21 and older can participate in licensed services without a prescription, a diagnosis, or a Colorado residency requirement. The licensed program currently covers psilocybin and psilocin only. As of June 2026, the Natural Medicine Advisory Board may expand it to include DMT, ibogaine, and mescaline. Like Oregon’s program, Colorado’s operates entirely under state law — psilocybin and psilocin remain Schedule I controlled substances under federal law.

The two tracks: licensed services and personal use decriminalization

Colorado’s framework is structurally distinct from Oregon’s in one important way: it includes a personal use decriminalization component that Oregon does not. Under Proposition 122 as implemented by SB 23-290, adults 21 and older may grow, possess, use, and share — without payment — personal quantities of psilocybin, psilocin, DMT, ibogaine, and mescaline (excluding peyote) on private residential property. Commercial sale, purchase, and unlicensed facilitation remain prohibited.

This decriminalization provision is separate from the licensed healing center program. It means that in Colorado, a person can legally grow and consume psilocybin mushrooms at home without going through a healing center. The licensed program exists alongside personal use, not instead of it, and provides a regulated, tested, professionally supervised option for those who want it.

Practically, the decriminalization track carries less protection than it might appear to. It covers personal use on private property only. It does not cover unlicensed facilitation of another person’s session, commercial activity of any kind, or use in public spaces. It does not create any federal protection. For participants seeking a structured experience with professional support and verified product quality, the licensed healing center track is the appropriate path.

How the licensed program is structured

Regulatory responsibility for Colorado’s program is split between two agencies. The Department of Regulatory Agencies (DORA) licenses and regulates facilitators through its Office of Natural Medicine. The Department of Revenue (DOR) licenses and regulates natural medicine businesses — healing centers, cultivation facilities, manufacturers, and testing facilities.

The program recognizes several types of licensed venues. A standard healing center is a dedicated facility for natural medicine services. A micro-healing center functions as an add-on for existing healthcare practitioners — a therapist’s office, wellness facility, or similar setting — and is designed for facilitators who will provide a smaller volume of sessions rather than operating as a specialized service center. The law also contemplates at-home administration in certain limited circumstances, though as of early 2026, DORA had restricted at-home facilitation to individuals receiving palliative care — a significant departure from what was expected when the rules were drafted.

The first state-regulated psilocybin session under the licensed program was conducted in Denver on June 6, 2025.

Who can participate

To access services at a licensed healing center, a participant must be 21 or older. No Colorado residency is required. No prescription or diagnosis is required. The facilitator conducts an initial consultation that includes a screening assessment to identify contraindications — including cardiovascular disease, uncontrolled hypertension, liver disease, seizure disorders, and severe chronic illness — and may require clearance from the participant’s treating provider before services begin. The screening determines whether a participant is appropriate for natural medicine services, not whether they have a qualifying diagnosis.

The session structure

Colorado’s licensed program uses the same three-part structure as Oregon’s: a preparation session, an administration session, and an integration session.

Initial consultation and preparation. The facilitator meets with the participant to complete intake paperwork and required disclosures, conduct the screening assessment, review informed consent, discuss intentions, and plan the administration session. The facilitator determines whether to proceed.

Administration session. The participant consumes psilocybin at the licensed healing center under the supervision of a licensed facilitator. Session duration is calibrated to dose — at minimum one hour per 2 milligrams of psilocin administered, and at least five hours for doses up to 50 milligrams. For higher doses, sessions run longer. Group sessions can accommodate up to 64 participants, a significantly higher cap than Oregon’s 25-participant limit.

Integration session. Following the administration session, the participant meets with the facilitator to process the experience, review safety and support planning, and connect with community resources as needed.

How Colorado differs from Oregon

The two programs share the same basic structure but differ in several important ways.

Personal use decriminalization. Colorado decriminalized personal cultivation and use of psilocybin — and four other natural medicines — at home. Oregon’s program has no comparable provision.

Group size. Colorado permits group administration sessions of up to 64 participants. Oregon caps groups at 25.

Location flexibility. Colorado’s framework was designed to allow administration at healing centers, micro-healing centers, certain healthcare facilities, and in limited circumstances at home. Oregon restricts administration to licensed service centers. The at-home provision in Colorado has been significantly narrowed by regulation as of early 2026.

Regulatory structure. Colorado splits licensing authority between DORA (facilitators) and DOR (businesses). Oregon centralizes both under OHA.

Substances. Both programs currently cover psilocybin and psilocin only. Colorado’s framework contemplates adding DMT, ibogaine, and mescaline as early as June 2026, subject to Advisory Board recommendation. Oregon’s program does not currently have a comparable expansion mechanism for these substances.

Stage of development. Oregon’s program launched in summer 2023 and has served an estimated 16,000 clients. Colorado’s first regulated session occurred in June 2025, and the program is in its early operational phase.

What the program currently covers

The licensed program is limited to psilocybin and psilocin through May 2026. Beginning June 1, 2026, the Natural Medicine Advisory Board may recommend adding DMT, ibogaine, and mescaline to the licensed program. In September 2025, the Advisory Board voted to recommend including ibogaine. Whether ibogaine will be formally added to the program, and on what timeline, will depend on DORA and DOR rulemaking following the Board’s recommendation. All of these substances remain Schedule I controlled substances under federal law regardless of Colorado’s authorization.

Cost and insurance

Colorado does not regulate or set prices for natural medicine services. Insurance does not currently cover licensed natural medicine services. Psilocybin remains a Schedule I substance federally, and insurance companies do not reimburse for Schedule I treatments. All costs are paid out of pocket. Pricing for Colorado healing center services was not yet well-established as of early 2026, given the program’s recent launch.

Colorado’s social equity provisions require the program to offer reduced licensing fees for facilitators from communities disproportionately affected by drug enforcement and reduced service fees for low-income individuals, though implementation of those provisions is ongoing.

What the program does not protect

The Colorado licensed program does not provide federal legal protection. Psilocybin and psilocin remain Schedule I under the CSA. Colorado’s personal use decriminalization similarly creates only state-law protection, not federal protection, and covers only the defined personal use conduct on private residential property.

Employment drug testing is not affected by participation in either the licensed program or the personal use decriminalization provision. A positive test result can result in adverse employment action regardless of state-legal status.

Colorado’s decriminalization of personal use does not authorize facilitation or commercial activity. A person who facilitates another person’s psilocybin session outside a licensed healing center is not protected by the personal use provision.

Common mistakes and misconceptions

“Colorado decriminalized psilocybin, so I can bring some home after my session.” The personal use decriminalization covers home cultivation and personal use on private residential property. Taking a product from a healing center off-site is not covered and is not analogous to purchasing from a cannabis dispensary. Products administered through the licensed program must be consumed on-site.

“Because personal use is decriminalized, I can run an unlicensed session for a group.” Personal use decriminalization covers individual personal conduct. Facilitating another person’s session — including a ceremony, retreat, or group session — without a license is not covered.

“Colorado’s program includes DMT and ibogaine now.” The licensed program is currently limited to psilocybin and psilocin. The Advisory Board voted to recommend ibogaine in September 2025, but addition to the program requires DORA rulemaking. The program expansion is not automatic or immediate upon the Board’s recommendation.
