Magic mushrooms in Denver: what's legal and where to go
Denver was the first U.S. city to decriminalize psilocybin, in 2019. Today Colorado law goes further: adults 21 and older can possess and grow natural psilocybin, and can take it at licensed healing centers, nine of which are listed in Denver. Buying and selling outside those centers is still illegal.

Are magic mushrooms legal in Denver?
For adults 21 and older, mostly yes. Colorado's Natural Medicine Health Act (Proposition 122, approved in 2022) and the 2023 law that implemented it make it legal for adults to possess, use and grow natural psilocybin mushrooms. Sharing with other adults is allowed only for free and, under a 2026 law (HB26-1325), only when the mushrooms are consumed at the time they're shared. Denver's own 2019 measure, Initiative 301, made psilocybin the city's lowest enforcement priority; it's now mostly overtaken by state law.
What's still illegal: selling or buying mushrooms outside the licensed system, possession under 21, and anything involving federal law, such as taking psilocybin across state lines or onto federal property.
Some Denver adults who aren't booking a healing center order products online instead, which isn't legal because Colorado law doesn't allow retail sales and federal law still applies. The retailer we know best publishes a Colorado-specific guide to microdosing mushrooms in Denver, including exact-milligram microdose capsules.

Denver's rules for natural medicine businesses
Denver requires healing centers to hold a local license on top of state licensing (centers that use only clinical facilitators are exempt), and its FAQ explains where they can operate. Public use is not allowed. If you're visiting, plan to use psilocybin at a licensed center or a private residence where you have permission, never in public or before driving.

Frequently asked questions
Can you buy magic mushrooms in Denver?
Not in a store. Colorado doesn't allow retail sales. You can pay a licensed healing center for a facilitated session that includes psilocybin taken on site, or, as an adult 21+, grow your own.
Is psilocybin decriminalized or legal in Denver?
Both, in a sense. Denver decriminalized in 2019, and Colorado legalized personal possession, use, growing and limited sharing for adults 21 and older statewide after voters passed Proposition 122 in 2022. Sales outside licensed healing centers remain illegal.
How many healing centers are in Denver?
Nine Denver healing centers were listed in the state's Healing Center Directory in October 2026, with more in surrounding suburbs. Statewide, 34 centers were licensed as of January 2026.
Can tourists use psilocybin in Denver?
Yes, if they're 21 or older. Colorado's law applies regardless of residency, and healing centers accept visitors. Don't take psilocybin out of Colorado; that's illegal under federal law and in every other state.
