Is Psilocybin Therapy Legal in Colorado?

Posted on by Carolina Correa

Yes. Psilocybin therapy is legal in Colorado at a state-licensed healing center, with a licensed facilitator present for the whole session. No prescription is needed. Adults 21 and over come to Denver for it from any state. Colorado checks your age and your screening, and it does not check where you live.

What did Colorado make legal, and when?

Colorado made supervised psilocybin sessions legal for adults 21 and over when voters passed Proposition 122, the Natural Medicine Health Act, in November 2022. The measure removed state criminal penalties for adults who possess, grow or share psilocybin mushrooms for personal use without payment, and it created a regulated program: psilocybin at a licensed healing center, under a licensed facilitator, with preparation before and integration after.

In May 2023 the legislature passed SB23-290, which put business licensing under the Department of Revenue, which created a Natural Medicine Division, and facilitator licensing under the Department of Regulatory Agencies. The state then spent two years writing the rules for healing centers, facilitator training, and testing and tracking of the medicine.

The Natural Medicine Division issued Colorado’s first healing center license on March 31, 2025, and the first licensed centers opened that year. Numia is a licensed psilocybin therapy center in Denver, and our therapists have guided over 200 legal psilocybin sessions. We opened in September 2025 under license NMHC-00022, and our work has been featured by ABC News, The New York Times and 9News.

Denver had moved earlier. In May 2019 Denver voters passed Initiated Ordinance 301, which made adult personal use and possession of psilocybin mushrooms the city’s lowest law enforcement priority. That vote did not make psilocybin legal. Proposition 122 did.

What is legal in Colorado, and what is not?

Supervised sessions at a licensed healing center are legal, personal use by adults is lawful under state law within limits, and selling psilocybin outside the licensed program is illegal everywhere in the state.

Legal:

  • A session at a licensed healing center for an adult 21 or over, with a licensed facilitator present (C.R.S. 12-170-104).
  • Personal use by adults 21 and over. Under C.R.S. 18-18-434, an adult who possesses, consumes, shares or grows natural medicine for personal use, without payment, does not break state law. Growing is limited to an enclosed and locked space of no more than twelve feet by twelve feet.

Not legal:

  • Selling psilocybin outside the licensed program. There is no dispensary and no take-home sale in Colorado. In the licensed program, the facilitator must watch you consume the medicine at the center (1 CCR 213-1 Rule 8030), and nothing leaves with you.
  • Possession or use by anyone under 21, a drug petty offense (C.R.S. 18-18-434(1)). A healing center must check a valid government ID before any session (1 CCR 213-1 Rule 8015).
  • Open and public use, also a drug petty offense (C.R.S. 18-18-434(2)).
  • Driving afterward. Driving under the influence of any drug is a crime in Colorado (C.R.S. 42-4-1301), and the state’s transportation department has said plainly that this includes psilocybin. The rules require a transportation plan in your record (4 CCR 755-1 Rule 6.3(B)), so we arrange your ride home in preparation.

Sessions take place at a state-licensed healing center, with a licensed facilitator present the entire time; at Numia, journeys are guided by licensed therapists who also hold the state facilitator license (Colorado’s rules also create a clinical facilitator license for licensed clinicians; our guide to therapist-led vs facilitator-led psilocybin therapy explains the difference).

How does a healing center license work, and how do I check one?

Two state agencies license this work, and both licenses are public records. The Colorado Department of Revenue’s Natural Medicine Division licenses natural medicine businesses under 1 CCR 213-1: healing centers, cultivators, product manufacturers and testing facilities. The Department of Regulatory Agencies, through its Office of Natural Medicine Licensure, licenses the people who hold sessions under 4 CCR 755-1: facilitators and clinical facilitators.

A healing center license lets a facility host licensed facilitators providing natural medicine services (C.R.S. 12-170-104). To hold one, a business shows the Division that local zoning permits the address, meets security and record-keeping rules, and receives medicine only from a licensed cultivator after testing by a licensed laboratory.

A facilitator license is personal, and it requires a DORA-approved training program. The clinical facilitator license is the tier for people who already hold a Colorado license to diagnose and treat, such as a psychologist, LCSW, LPC, LMFT, LAC, physician, nurse practitioner or physician assistant (4 CCR 755-1 Rule 2.5). Numia’s model is the licensed facilitator therapist: a licensed therapist who also holds Colorado facilitator licensure.

To check a license:

  • Healing centers: the Natural Medicine Division’s facility license verification tool searches by license type, number, facility name or city. Our license number is NMHC-00022.
  • Facilitators: DORA’s Verify a License tool. Ask any facilitator for their license number; we will give you ours.

What is the federal position?

Federal law has not changed. Psilocybin and psilocin are Schedule I substances under the Controlled Substances Act (21 CFR 1308.11(d)), and the FDA has not approved psilocybin as a medicine. Colorado law protects this work within the state’s regulated program, and those protections are state protections. Cannabis has lived with the same split here for more than a decade.

The FDA granted breakthrough therapy designation to a psilocybin research program for depression in 2018 and to a second in 2019; that designation speeds review of a drug in trials and is not an approval. Nothing in Colorado’s program has been evaluated or approved by the FDA, including our services. We are not lawyers. A federal job, a security clearance or a professional license is a question for a lawyer, and worth asking before you plan a trip.

What if I am visiting from another state?

Colorado’s law applies to you while you are in Colorado, and adults 21 and over come to Denver for this from any state. A healing center must check a valid government ID, and the accepted forms include a driver’s license or ID card from any US state, a passport, a military ID or a permanent resident card (1 CCR 213-1 Rule 8015). There is no residency requirement, no waiting period and no prescription.

When you go home, your home state’s law applies. Psilocybin is a Schedule I substance under federal law everywhere, and in most states it remains illegal under state law. You will not be carrying psilocybin, so there is nothing to possess. The trip is three days in Denver: the day before for in-person preparation, the session day, and the day after for the first integration session. Nobody drives or flies on the session day.

Is “magic mushroom therapy” the same thing?

Usually no. People who search for magic mushroom therapy in Denver mean one of three things, and only one is a licensed session.

  1. A session at a licensed healing center. This is what Colorado’s program regulates, and it is what we do.
  2. Personal use at home. This is lawful for adults under state law, within the limits above, and unsupervised. Nobody is required to screen you, test the mushrooms, measure the dose or stay with you.
  3. An unlicensed guide, sitter or retreat that charges for psilocybin. This sits outside the law. Nobody may sell psilocybin outside the licensed program, and the state licenses the people who hold sessions, so you can check a person’s license.

A licensed session comes with requirements that unsupervised use does not: lab-tested medicine with the dose measured in milligrams of psilocin and set with you in preparation, a written safety screening, informed consent, a licensed facilitator who stays for the whole session, a transportation plan, and integration afterward. Who should not take psilocybin, and how our screening works, is on our page is psilocybin therapy safe.

Common questions

Are magic mushrooms legal in Denver?

Under Colorado law, yes for adults 21 and over, within limits. An adult may possess, grow in a locked space and share psilocybin mushrooms for personal use without payment, and may receive a supervised session at a licensed healing center. Selling them outside the licensed program remains illegal, public use is a petty offense, and psilocybin remains a Schedule I substance under federal law.

Do I need a prescription?

No. Colorado does not require a prescription, a diagnosis or a referral. It requires that you are 21 or older and that a licensed facilitator screens you first; when the screening finds risk factors, the rules require a referral, medical clearance or a provider consultation before a session can go ahead (4 CCR 755-1 Rule 6.16(F)). Questions about your medications belong with your prescriber.

Do I need to be a Colorado resident?

No. The rules accept a valid driver’s license or ID card from any US state, a passport, a military ID or a permanent resident card (1 CCR 213-1 Rule 8015). Most of our clients travel from outside Colorado.

Can I take psilocybin home?

No. In the licensed program the medicine is consumed at the center, in front of your facilitator, and anything unconsumed is disposed of or returned to locked storage (1 CCR 213-1 Rule 8030). There is no take-home sale in Colorado, and carrying it across state lines is a federal matter.

Can I be arrested after a session?

Not under Colorado law for taking part in a licensed session. Receiving natural medicine services at a licensed healing center is lawful for an adult 21 or over, and you leave with nothing to possess. What can get you into trouble on the way home is driving, a DUI under C.R.S. 42-4-1301, which is why a ride home is arranged before the session. Federal law has not changed.

Is psilocybin legal for anyone under 21?

No. A person under 21 who possesses or consumes natural medicine commits a drug petty offense (C.R.S. 18-18-434(1)), sharing with anyone under 21 is prohibited, and a healing center must verify age with a valid ID before any session (1 CCR 213-1 Rule 8015). Colorado’s program is for adults only, and so are we.

Is psilocybin approved by the FDA?

No. Psilocybin is a Schedule I substance under federal law, and the FDA has not approved it as a medicine. The FDA has granted breakthrough therapy designation to two psilocybin research programs for depression, in 2018 and 2019, which speeds the review of a drug in trials. Colorado’s program, and our services within it, have not been evaluated or approved by the FDA.
