- Checked against 2 cited sources at this review.
1. What the law is
Psilocybin and psilocyn are listed in Schedule I at Wyo. Stat. section 35-7-1014(d)(xix) and (xx), with the penalties at section 35-7-1031(c).1
Wyoming keeps psilocybin and psilocyn in Schedule I, at section 35-7-1014 of the state statutes, with the penalties at section 35-7-1031. As of 2026 the legislature has not taken up a psilocybin bill and none has been enacted.
Psilocybin is illegal in Wyoming, where it is classified as a Schedule I controlled substance under the Wyoming Controlled Substances Act. Wyo. Stat. Ann. § 35-7-1014 lists psilocybin and psilocyn among the Schedule I hallucinogenic substances, the category the statute reserves for substances the legislature has determined have no accepted medical use and a high potential for abuse. Unlawful possession, manufacture, and delivery are prohibited and penalized under Wyo. Stat. Ann. § 35-7-1031.
Wyoming has not enacted any statute, ballot measure, or pilot program that legalizes, decriminalizes, or otherwise creates legal access to psilocybin, and as of 2026 no such reform is in effect. Psilocybin's Schedule I placement derives from the state's adoption of the Uniform Controlled Substances Act framework, codified at Wyo. Stat. Ann. § 35-7-1014, and the legislature has not amended that section to reschedule or exempt psilocybin. Because no reform law exists, possession of psilocybin remains a criminal offense statewide and the substance carries no current lawful path for personal, supervised, or therapeutic use under Wyoming law.
