Colorado's new natural medicine law: an ibogaine pilot and on-site sales

What HB26-1325 does

Colorado's HB26-1325, titled "Natural Medicine", was signed by the governor in early June 2026. The legislature's final fiscal note dates the signature June 4.¹ The fiscal note says the law takes effect August 12, 2026, except most subsections of the bill's Section 2, which take effect only once the state receives $150,000 in gifts, grants or donations; the ibogaine pilot depends on that money.¹ The fiscal note describes these main pieces:¹

• An ibogaine research pilot. If the money and federal approval come through, the Behavioral Health Administration will run a pilot on whether ibogaine is safe and effective for mental health conditions and substance use disorders. Up to five pilot sites may be approved, and the agency is to help them file an investigational new drug application with the federal government.
• A new sales license. The "limited regulated natural medicine sales license" lets a licensee co-located within a healing center sell natural medicine to people taking part in an administration session.
• Facilitator liability. Facilitators are liable for money damages in a malpractice case only if an injury was the direct result of intentional misconduct, gross negligence or a departure from the standards of practice.
• Other changes. Changes to the Natural Medicine Advisory Board, a priority order for business licenses (pilot participants first, then applicants with Colorado residency), the end of a five-license cap on facilitators' financial interests, and power for the division director to issue cease-and-desist orders.

How the sales license works

Colorado's Natural Medicine Division put the license into its rules with emergency rules adopted August 11 and effective August 12, 2026.³ Under Rule 8006, a healing center owner may get the license "to conduct sales of Regulated Natural Medicine and Regulated Natural Medicine Product to Participants immediately preceding Administration Sessions."²

The limits are tight. A licensee may not sell for use anywhere other than the co-located healing center's licensed premises, may not repackage or relabel product, may buy only from the two kinds of licensed natural medicine suppliers the rule names, and must check each participant's ID the same way healing centers do.²

The advertising language

The final fiscal note presents the bill's advertising language as a clarification of existing law, not a new ban. It says the bill "clarifies that state law does not permit a person to" advertise bona fide harm reduction or support services (unless the activity falls under the definition of personal use), advertise natural medicine or natural medicine products, or use harm reduction or support services to conduct sales of natural medicines.¹ We haven't been able to read the enrolled bill text, so we can't say whether it changes what licensed healing centers may advertise.

What it means if you're in Nevada

For a Nevadan, the change is in how a session's medicine can be paid for, not where it can go. Healing centers and sales licensees must confirm that a participant is 21 or older, and the rules accept a driver's license or ID card from any US state.² We found no rule limiting participants to Colorado residents; the residency preference in HB26-1325 applies to business licenses.¹² The nearest licensed healing center to Las Vegas is in Durango, about 537 miles by road.⁷ Our list of legal psilocybin services nearest Las Vegas has the rest.

Anything bought under the new license is for use at that healing center only.² Psilocybin is a Schedule I drug under federal law and Nevada law, and Colorado's law changes neither; carrying it back to Nevada would be illegal.⁵⁶ The ibogaine pilot is for research sites, not visitors. See Nevada psilocybin law for penalties and our visitor guide for travel questions.
