Colorado has become one of the most talked-about places in the country when it comes to psychedelics. After voters approved the Natural Medicine Act, many people walked away with one big question: So… are mushrooms actually legal now?
The truth is more nuanced. Colorado didn’t suddenly turn psilocybin into something you can buy at a store or use however you want. Instead, the state created a layered system that includes decriminalized possession, legal personal cultivation, and a regulated service model where adults can access psilocybin through trained facilitators.
If you’ve been confused by headlines or conversations online, you’re not alone. This guide walks through what the law actually says, in real terms, so you can understand how Colorado’s approach really works today.
What Colorado Actually Legalized
Colorado’s Natural Medicine Act (also called Proposition 122) reshaped how the state handles psilocybin and a handful of other naturally occurring psychedelic compounds. But it didn’t create a free-for-all. Instead, it introduced a measured system designed around education, harm reduction, and regulated access.
The Natural Medicine Act Explained Simply
In 2022, Colorado voters approved a ballot measure that reclassified certain natural psychedelics as “natural medicine.” This category includes psilocybin and psilocin (the active compounds in psychedelic mushrooms), along with several other substances that may be considered for future regulation.
The intent wasn’t to recreate a traditional retail model. Instead, the law focuses on supervised experiences and personal possession rights. The act also created a statewide regulatory framework to license “healing centers,” where trained facilitators can guide adults through psilocybin experiences.
Legal vs. Decriminalized: What’s the Difference?
This is where people often get tripped up.
-
Decriminalized means adults won’t face criminal penalties for certain activities connected to personal use, possession, or sharing in non-commercial ways. It doesn’t mean the activity is fully legalized or regulated.
-
Legal applies to specific actions defined under state law, for example, adults participating in psilocybin sessions at licensed healing centers, or growing mushrooms at home for personal use.
Retail sales, commercial growing operations, and anything involving minors remain prohibited.
Personal Use, Sharing, and Possession
Colorado’s new framework gives adults more freedom with natural psychedelics than almost anywhere else in the United States. But the law is carefully structured, and it’s important to understand where the boundaries are.
What Adults Can Legally Do
Under the Natural Medicine Act, adults 21 and older may:
-
Possess psilocybin and psilocin for personal use
-
Use these products – like microdose mushroom tablets – privately
-
Share them with other adults in non-commercial, no-payment contexts
-
Grow mushrooms at home, as long as it’s for personal use
-
Participate in licensed, facilitator-guided sessions at approved healing centers
These allowances are meant to support personal, adult-directed use, not commercial activity.
What’s Still Not Allowed
Even with decriminalization in place, Colorado keeps several firm lines in place:
-
You cannot sell psilocybin or psilocybin-containing mushrooms
-
You cannot run a distribution network
-
You cannot transport mushrooms across state lines (federal law still applies)
-
You cannot provide mushrooms to minors
-
You cannot operate a psilocybin business outside the licensed healing-center system
Colorado’s approach expands personal freedom, but it doesn’t permit an unregulated market.
Cultivation Rules in Colorado
One of the most unique parts of Colorado’s law is that it explicitly includes the right to cultivate mushrooms at home, but only for yourself or a small group of adults, with no money exchanged.
Home Growing for Personal Use
Adults 21+ are allowed to:
-
Grow psilocybin mushrooms at home
-
Store them privately
-
Share them with other adults (as long as it’s not commercial)
This mirrors the way Colorado treats personal cultivation of cannabis, but the two systems are not identical. Psilocybin doesn’t have a licensing system for growers, and there is no legal pathway for anyone to sell what they produce.
What Crosses Into Illegal Territory
Large-scale or organized cultivation becomes illegal quickly. Activities that may put someone outside the law include:
-
Growing in quantities that appear intended for distribution
-
Accepting payment in any form
-
Supplying commercial operations
-
Transporting mushrooms across state lines
The law’s intention is simple: personal mushroom growing is allowed. Anything resembling commerce is not.
Colorado’s Licensed Healing Centers
The most regulated piece of Colorado’s system is the creation of Natural Medicine Healing Centers, supervised locations where adults can access psilocybin through a guided session.
What Healing Centers Are (and Aren’t)
Healing Centers are not dispensaries. They don’t sell mushrooms to take home, and they don’t operate like cannabis shops. Instead, they’re places where adults participate in facilitated psilocybin sessions overseen by licensed professionals.
These centers are required to follow state-approved safety standards, facilitator training requirements, and integration guidelines designed to help people prepare for and process their experiences.
Accessing Psilocybin Through a Facilitator
Licensed facilitators are trained to create a supportive environment, explain the process, and monitor the session itself. They don’t prescribe or diagnose. Their role is to guide, observe, and maintain a safe setting.
Because the program is still rolling out, availability varies depending on where you live in Colorado, and many counties are still developing their local rules.

How Colorado’s Psilocybin Laws Compare to Other States
Colorado is one of only two states, along with Oregon, to adopt a statewide regulated model for psilocybin. Everything else in the country falls into one of two categories: decriminalization at the city level or complete prohibition.
Only Two States Have Legal Frameworks
-
Oregon created the first supervised psilocybin services program.
-
Colorado followed with its own, using a slightly broader “Natural Medicine” framework.
Both states prohibit retail sales, possession by minors, and unlicensed distribution.
Decriminalization Efforts Elsewhere
Several cities, such as Oakland, Denver, Seattle, and Detroit, have passed decriminalization measures that shift law enforcement priorities. But these policies vary widely, and they don’t create legal access pathways.
Colorado’s model remains one of the most structured and clearly defined.
Common Misunderstandings About Colorado Mushroom Laws
Because headlines tend to oversimplify complex laws, Colorado’s psilocybin framework is often misunderstood. Here are the clarifications readers look for most.
“Legal” Doesn’t Mean Retail Sales
A common misconception is that voters created a system where people can buy psilocybin the way they buy cannabis. That isn’t the case.
There are no psilocybin stores in Colorado, and no products are currently available for public purchase. To learn more, check out our detailed guide on where can I buy microdose mushroom gummies?
“Decriminalized” Doesn’t Mean Risk-Free
Decriminalization removes criminal penalties for certain adult behaviors, but it doesn’t shield against violations of federal law or activities outside the permitted framework. It also doesn’t create commercial opportunities.
Colorado’s system is careful and controlled by design.
A Quick Timeline of Colorado’s Psychedelic Reform
Understanding how Colorado arrived here helps explain the current rules:
-
2019: Denver becomes the first U.S. city to decriminalize psilocybin.
-
2022: Statewide approval of the Natural Medicine Act.
-
2023–2024: Regulatory boards develop the licensing and training process for facilitators and healing centers.
-
2025: Healing centers begin opening under state oversight, and personal use/decriminalization rules are fully in effect.
The state continues refining the program as more counties participate.
The Bigger Picture: Why Colorado Took This Approach
Colorado’s voters approved the Natural Medicine Act for several reasons, but the law itself focuses on three priorities: education, safety, and controlled access.
Harm Reduction and Controlled Access
By moving personal possession and use into a decriminalized category, while also creating a regulated service model, Colorado aimed to reduce penalties and improve safety for adults choosing to explore psilocybin.
The framework doesn’t encourage use. It creates a structured environment for people who would otherwise have no safe or legal pathway.
Education and Safety as Core Themes
The law includes guidelines for facilitator training, preparation, and integration support. Healing centers are designed to be professional spaces where adults can participate with informed expectations, oversight, and post-session reflection.
Colorado’s approach emphasizes informed decision-making rather than commercial expansion. If you’re curious about microdosing mushrooms, we crafted a user-friendly guide on how long does a mushroom microdose last?
