The Colorado Natural Medicine Health Act (NMHA): The Consumer Guide to Legal Magic Mushroom Experiences

It’s 2026, and Colorado has officially become a global leader in the regulated use of psychedelic medicine. With the full implementation of the Natural Medicine Health Act, the state has moved beyond simple decriminalization to create a structured, legal ecosystem for psilocybin, the active compound in magic mushroom experiences. Whether you’re a lifelong Colorado resident or a traveler looking for legal magic mushrooms, the landscape has changed. Here is what you need to know about access, safety, and your rights.

What is the Natural Medicine Health Act?

At its core, this law, initially passed by voters as Proposition 122, aims to provide a safe and legal way for adults 21 and older to access natural medicines. Under the NMHA, “Natural Medicine” is defined as psilocybin, psilocin, dimethyltryptamine (DMT), ibogaine, and mescaline (specifically excluding peyote to protect indigenous conservation efforts).

The Act creates a dual-track system for these substances. It immediately decriminalized the personal possession, growth, and sharing of all five of these medicines for adults. However, it also established a “Regulated Access” model that currently only applies to psilocybin and psilocin. While you can legally use any of the five substances privately, the state only licenses facilitators and healing centers to professionally administer psilocybin at this time.

For Colorado Residents: Personal Use

If you live in Colorado, the law provides a high degree of freedom for your own personal healing journey.

• Cultivation: Adults 21+ can legally grow their own natural medicine at home. There are no state-level plant counts for personal growth, though it must be kept in a secure, private space that’s inaccessible to minors.
• Possession and Sharing: You can legally possess and share natural medicine with other adults, provided there is no compensation. You cannot sell mushrooms from your home.
• Harm Reduction: You can legally pay for support services. This means you can hire a trip-sitter or an integration coach to help you navigate your experience, as long as you provide your own home-grown medicine and are not buying the substance from them.

For the Traveler: How to Have a Magic Mushroom Experience in Colorado

If you’re visiting Colorado specifically for a psilocybin experience, you can’t walk into a retail store and buy a bag of magic mushrooms like you would buy cannabis. Colorado has rejected the dispensary model for psychedelics. Instead, you must go through a Licensed Healing Center.

Once you’ve selected a healing center and gone through their preliminary screening process, the magic mushroom experience itself involves three distinct stages:

1. Preparation: You’ll meet with a Licensed Facilitator for an in-depth screening. They’ll check for medical contraindications (like certain heart conditions or medications) and help you set an intention.
2. Administration: This is the journey itself. You consume the medicine at the Healing Center under the constant supervision of the facilitator. They’re there to ensure your physical and emotional safety throughout the 4-6 hour experience.
3. Integration: After the effects wear off, you’ll have a session to talk through what you saw and felt. It’s designed to help you bring the lessons of the journey back to your daily life.

The Ibogaine Exception: Decriminalized but Not Yet Regulated

While the Colorado Natural Medicine Health Act covers a variety of substances, Ibogaine currently occupies a unique middle ground in Colorado. Under the state’s personal use provisions, it’s decriminalized for adults 21 and older to possess, grow, and use ibogaine for personal healing. However, unlike psilocybin, ibogaine doesn’t yet have a “Regulated Access” model. This means that while you can possess it in your home, it’s not legal to pay for ibogaine treatment or sessions within the state.

Because ibogaine carries specific cardiac risks that require intense medical monitoring, it’s often described as more of a “surgical” procedure than a typical psychedelic journey. In late 2025, the Natural Medicine Advisory Board voted to recommend adding ibogaine to the regulated model, but until those specific rules are finalized and licenses are issued, there are no legal “Ibogaine Healing Centers” in Colorado. For now, any business charging for ibogaine administration is operating outside the law. The regulated path is currently reserved exclusively for psilocybin.

What You Still Can’t Do

Even in Colorado, there are strict red lines to be aware of that should not be crossed.

• No Public Use: Consuming magic mushrooms in public spaces, parks, or on the streets is still illegal and can lead to fines or arrest.
• No Driving: Operating a vehicle while under the influence of natural medicine remains a serious crime (DUI).
• Federal Lands: A huge portion of Colorado is Federal land (including Rocky Mountain National Park). Because mushrooms remain federally illegal, possessing them on these lands is a federal crime, regardless of state law.
• No Retail Sales: There are no “shroom shops.” If someone is selling magic chocolate bars over a counter in a retail setting (or on a street corner!), they are operating outside the regulated Natural Medicine Health Act system.

Colorado’s model is built on the idea that these are powerful tools that require a carefully curated set and setting for safety. By prioritizing supervised use over retail sales, Colorado is betting that a therapeutic approach will lead to the best outcomes for consumers.
