Ketamine or Psilocybin in Colorado: How to Choose
Two medicines, two laws, two very different afternoons.
Colorado gave her two options, and somehow that made it harder.
In most states the question is whether. Here, it's which. Ketamine with a prescription, or psilocybin at one of the state's new licensed healing centers. Her friend did mushrooms in Boulder and won't stop talking about it. Her therapist mentioned ketamine. Every article she reads treats them like the same thing with different branding.
They're not. Here's how they actually differ in Colorado, and how to think about which fits you.
The quick comparison
| Ketamine | Psilocybin | |
|---|---|---|
| Legal path | A prescription medicine. You need a licensed prescriber | Colorado's Natural Medicine program. Licensed facilitator, licensed healing center, adults 21+ |
| Where it happens | A clinic, or at home | On site at the healing center. The medicine doesn't go home with you |
| How long it lasts | Shorter. A ceremony fits inside an afternoon | Longer. Usually most of a day |
| How often | Often repeated in a series, or on a regular rhythm | Often one experience with preparation and integration around it |
| Cost | Wide range: per infusion, per pack or monthly | Roughly $1,500–$3,500 at licensed centers, out of pocket |
Two things in that table matter more than the rest: where it happens, and how often.
Psilocybin in Colorado, briefly
Voters approved Colorado's Natural Medicine Health Act in 2022. The first healing center license went to a Denver center in March 2025, and by early 2026 the state had approved 34 licensed healing centers, with more applications pending. The process at a licensed center usually has three parts: preparation meetings, the day you take the medicine on site with a facilitator, and integration meetings afterward. Some centers charge around $3,500 for all three; Boulder centers opened at about $1,500 to $3,400. Insurance doesn't cover it.
Adults in Colorado can also grow mushrooms at home and share them with other adults, but selling them is illegal. That's outside the licensed system, with none of its screening or support. This post isn't advice about using them.
Ketamine in Colorado, briefly
Ketamine is an FDA-approved anesthetic that providers prescribe off-label for mood and mental health. It can be given by IV in a clinic, by injection, or as a lozenge taken at home. At-home prescribing without an in-person visit is allowed through December 31, 2026 under a temporary federal rule. The full legal picture is in Is Ketamine Legal in Colorado?
The question isn't which medicine is stronger. It's which kind of help fits the life you're actually living.
How to choose
Neither is better. They're built for different things. A few honest questions help.
- Do you want one big experience, or a rhythm? Psilocybin at a healing center is often a single, long, deep day. Ketamine tends to work as something you return to, which makes it easier to build practice around.
- Where do you want to be? A healing center means a dedicated space away from home, and someone to drive you. Ketamine can happen in your own bed, which some women find safer and others find too close to everyday life.
- How much of a day can you give it? Psilocybin usually asks for most of a day, plus recovery. A ketamine ceremony can fit into an afternoon and evening.
- What does your medical picture say? Some health conditions and medications rule out one, the other or both. That's a conversation for a licensed provider, not a blog post.
- What happens afterward? Either medicine can open something. Ask both options what support looks like in the month after, not just the day of.

Is RESET right for me?Why RESET uses ketamine
RESET is built around a monthly rhythm: two live workshops on one skill, a ceremony, and the Studio for practice, ongoing. That rhythm is the point, and ketamine fits it. A shorter experience you can return to each month, at home, with a facilitator present live the whole time and a physician evaluation first, lets the work build month over month instead of resting on a single day.
That doesn't make psilocybin the wrong choice. For some women one deep day at a licensed center is exactly right. If that's you, ask the center the same questions you'd ask anyone: who's with me, what's the screening, and what happens after.
If you're not ready for either, the Studio is a place to start the practice without medicine.

Is RESET right for me?This post is educational. It is not medical advice and not a recommendation to use any substance. Well Dosed does not give dosing advice about psilocybin. Whether either medicine is safe for you is a question for a licensed medical provider. Colorado's rules are still changing; verify any provider's license before you book. Last reviewed October 2026.
