If you are looking for legal access
The nearest legal option to Wyoming is Colorado
Colorado runs a licensed supervised-access program with no residency requirement, so people do travel for sessions. Expect roughly $1,000–$3,500 out of pocket — no insurer covers it.
You cannot lawfully bring psilocybin back to Wyoming. Possession outside the licensed system is a crime in Colorado too, and carrying it across state lines is a federal offense.
This entry records the absence of reform rather than a specific program, so it rests on the state’s controlled-substances schedule rather than a source we link. If Wyoming has changed something we have missed, tell us — corrections are published with a dated note.
