Is Psilocybin Therapy Legal in Colorado? What Proposition 122 Actually Means for You
This is one of the first questions I hear from people who are curious but want to be careful and informed, which, honestly, is exactly the right orientation. Let's clear it up completely, because the answer is worth understanding in some detail.
In November 2022, Colorado voters passed Proposition 122, the Natural Medicine Health Act, making Colorado the second state in the country (after Oregon) to establish a regulated framework for therapeutic psilocybin use.

In practical terms, what Colorado’s Natural Medicine Health Act created are two distinct legal pathways. They're quite different from each other, and knowing the difference matters.
Personal use
Adults 21 and older in Colorado may legally possess, use, and share (though not sell) psilocybin mushrooms in private settings. This provision went into effect in 2023. It's a meaningful and significant shift in how our state approaches these medicines, though it doesn't, on its own, create a pathway for facilitated therapeutic services provided by another person. That's the second pathway.
The regulated healing center model
Beginning in 2025, licensed healing centers like The Clearing can legally provide psilocybin-assisted therapy to adults under the supervision of state-licensed facilitators in approved facilities. This is the model we operate within, and it's the one most closely aligned with what the clinical research has been studying and validating over the past decade or so.
Choosing this model means working within a system specifically designed for safety, clinical accountability, and therapeutic integrity. Licensed facilitators complete rigorous training programs, pass background checks, and meet ongoing licensure requirements. The psilocybin medicine comes from licensed cultivators and goes through independent quality testing at certified laboratories. The center itself is inspected and regulated by the state. All of that exists for good reason: these are powerful medicines, and the infrastructure around their therapeutic use exists to protect the people engaging with them.
Beyond legal protection, the regulated model provides something I think is equally important: a structured therapeutic container. Preparation, administration, and integration aren't optional extras in this model, they are required components, because the research is consistent that the set, setting, and clinical support surrounding a psilocybin experience shape its outcomes as meaningfully as the medicine itself.
What is still federally restricted
Psilocybin remains a Schedule I controlled substance under federal law. That means it cannot be prescribed by a physician, it is not covered by health insurance (something advocates are actively working to change), and it cannot travel across state lines. Licensed healing centers operate in a state-legal space that exists in some real tension with federal law. For most clients, the practical implications of that tension are minimal in daily life, but it's worth understanding clearly, because informed clients are better-served clients.
It's also worth being specific about something: the personal use provision does not create a legal pathway for someone to facilitate a psilocybin experience for another person outside of a licensed center. If you're ever evaluating an arrangement that involves facilitation outside the licensed model, please understand what that means from a legal standpoint so you can make a fully informed decision.
Why the regulated framework genuinely matters to us
I'll be honest: I'm grateful for the structure that Prop 122 created, not because it makes our work simpler (it doesn't, particularly), but because it creates the conditions for the kind of care I believe every person working with these medicines deserves. Clinical screening, relationship-based preparation, trauma-informed facilitation, and supported integration are not bureaucratic hurdles. They are the infrastructure of healing that actually lasts.
