Are Psilocybin Mushrooms Legal in Colorado?

Last updated July 4, 2026 · Personal-use rules come from Proposition 122; retail sale and federal status are unchanged.

What the Law Says: Proposition 122

In November 2022, Colorado voters passed Proposition 122, the Natural Medicine Health Act. It did two distinct things at once — and understanding the difference is the whole point of this page.

First, it decriminalized personal use of certain natural psychedelics — including psilocybin and psilocin (the compounds in "magic mushrooms") — for adults 21 and older. Possessing, growing, and sharing these substances without payment is no longer a crime under state law.

Second, it created a state-regulated "Natural Medicine" program: a licensing framework for healing centers where adults can receive psilocybin under a trained, licensed facilitator. Colorado's Department of Regulatory Agencies (DORA) built the rules, and the first licensed centers began operating in 2025. (Sources: Proposition 122 text, CO Secretary of State; DORA Natural Medicine Division.)

This makes Colorado the second state after Oregon to create legal, supervised psilocybin access — and it went further than Oregon by also decriminalizing personal possession and home cultivation statewide.

What's Legal in Colorado

For adults 21 and older, Proposition 122 makes the following legal under state law:

• Possessing psilocybin mushrooms for personal use.
• Growing your own at a private residence for personal use — not for sale.
• Sharing or gifting to another adult 21+, as long as no money changes hands.
• Supervised use at a licensed healing center with a trained facilitator.

The law also covers a short list of other natural psychedelics (including DMT, ibogaine, and mescaline that is not derived from peyote), but psilocybin mushrooms are the substance most people are asking about.

What's Still Illegal

Legal for personal use is not a free-for-all. These remain illegal in Colorado:

• Selling psilocybin. There is no retail market. Buying or selling mushrooms — including at a "dispensary," gas station, or online — is not what Proposition 122 legalized.
• Anyone under 21. Possession and use by minors remains prohibited.
• Driving under the influence. Impaired driving laws apply to psilocybin exactly as they do to alcohol or any other substance.
• Use in public or crossing state lines. Take mushrooms into a state where they're illegal — or onto federal land — and that state's (or federal) law applies.

And the constant backdrop: psilocybin is still a Schedule I substance under federal law. Colorado's changes are state-level. On federal property, or if federal authorities choose to act, federal law still governs. (Source: DEA Drug Fact Sheet.)

Healing Centers: Legal Supervised Use

The regulated side of Proposition 122 is the healing center. This is the only setting in Colorado where psilocybin is administered in a formal, licensed context. Here's how it works:

• You must be 21 or older. No prescription or diagnosis is required — this is not a medical prescription model.
• Sessions happen at a licensed healing center with a state-licensed facilitator present, typically across a preparation session, the dosing session itself, and an integration session afterward.
• You cannot buy mushrooms to take home. The psilocybin is administered on-site.

This is the closest thing Colorado has to "legal psilocybin therapy," though the state deliberately avoids the word therapy in the licensing framework. (Source: Colorado DORA — Natural Medicine Division.)

Denver & Local Decriminalization

Colorado's shift didn't start with Proposition 122 — it started in Denver. In May 2019, Denver became the first city in the United States to decriminalize psilocybin mushrooms, making personal possession the lowest law-enforcement priority. That local vote helped set the stage for the statewide measure three years later.

Today, statewide decriminalization under Proposition 122 means the practical question in Denver, Boulder, Colorado Springs, or anywhere else in the state is the same: personal use by adults 21+ is decriminalized; selling is not.

Growing Your Own & the Spore Question

Colorado is one of the few places where growing psilocybin mushrooms at home for personal use is legal under state law for adults 21+. You cannot grow to sell, and you're still exposed to federal law, but personal cultivation is squarely within what Proposition 122 allows.

On spores: mushroom spores contain no psilocybin until they germinate, which is why they're legal to buy in most of the country. Colorado places no restriction on spores. Elsewhere, four states do: California, Georgia, and Idaho ban psilocybin mushroom spores outright by statute, and Florida is a gray area — it prohibits cultivation, and spore possession sits in a legal gray zone, so most vendors won't ship there. In Colorado, because home cultivation itself is legal for personal use, the "spore loophole" that matters elsewhere is largely moot. (Source: Legal status of psilocybin mushrooms — Wikipedia.)

"Magic Mushroom" Gummies in Stores — Read First

If you see "mushroom gummies" or "psychedelic chocolate bars" sold openly in a Colorado smoke shop or gas station, they usually do not contain real psilocybin — because there's no legal retail market for it. These products often use:

• Amanita muscaria (muscimol) — a legally-gray but chemically different mushroom with its own risks, or
• Unregulated synthetic or research chemicals that may not be accurately listed on the label.

Because they're unregulated, contents and dosing are inconsistent, and some products have been linked to hospitalizations. If it's on an open shelf with a price tag, that alone tells you it isn't the regulated psilocybin of Proposition 122. (Source: TIME.)

The Bottom Line

Colorado is one of the most permissive states in the country for psilocybin. Adults 21+ can possess, grow, and share mushrooms for personal use, and can access them at licensed healing centers under Proposition 122. What the state did not do is create a retail market — you cannot legally buy or sell psilocybin in Colorado — and none of it changes its federal Schedule I status.

Legal for personal use is not the same as a store shelf. In Colorado, the difference is the whole law.
