Psilocybin is fully illegal in Wyoming in 2026 — a Schedule I controlled substance with no medical program, no decriminalized cities, and no regulated access of any kind.
Wyoming remains one of the most restrictive states in the country for psilocybin, and nothing has changed heading into 2026. Psilocybin and psilocin sit in Schedule I of the Wyoming Controlled Substances Act, which means the mushrooms themselves, extracts, and edibles are all illegal to possess, grow, or sell anywhere in the state. There is no medical program, no decriminalized city, and no ballot initiative in progress — the Legislature did not take up a single psychedelics bill in its 2024, 2025, or 2026 sessions, and its one attempt to soften possession penalties generally, HB0030 in 2024, died in the Senate. Wyoming law is also unusually strict in one respect: simply being under the influence of a Schedule I, II, or III substance is its own misdemeanor, separate from possession. For residents interested in legal access, the practical reality comes down to geography. Colorado, immediately south, runs a regulated natural medicine program where adults 21 and over can book supervised psilocybin sessions at licensed healing centers — while at home in Wyoming, only non-psychoactive functional mushrooms and unscheduled amanita muscaria products are legal to buy.
Possession
Possessing psilocybin mushrooms is a crime everywhere in Wyoming. Up to 3 ounces in plant form is a misdemeanor carrying up to 12 months in jail and a $1,000 fine; larger amounts — or a third possession conviction — are felonies punishable by up to 5 years.
Cultivation
Growing psilocybin mushrooms is treated as manufacturing a Schedule I controlled substance, a felony punishable by up to 10 years in prison and a $10,000 fine.
Retail / purchase
No form of psilocybin can be legally bought or sold anywhere in Wyoming — there are no licensed centers, dispensaries, or state programs. The only mushroom products sold legally in the state are non-psychoactive functional mushrooms and amanita muscaria products, which are not scheduled under state or federal drug law but are also not authorized by the FDA as ingredients in conventional food.
Spores
Wyoming law does not name psilocybin spores, and because dormant spores contain no psilocybin they fall outside the state's Schedule I listing, so holding them for microscopy or taxonomy sits in a legal gray zone rather than being clearly criminal. That is not true everywhere: California, Georgia, and Idaho ban spores outright, and since 2025 Florida has prohibited selling, transporting, importing, furnishing, or giving them away (Fla. Stat. 500.75, a first-degree misdemeanor), so the ban list is growing and should be rechecked before ordering from any vendor. Germinating spores in Wyoming is a different matter: once mycelium begins producing psilocybin it becomes manufacture of a Schedule I substance, a felony carrying up to 10 years.
Amanita muscaria
Amanita muscaria is not a controlled substance under Wyoming or federal law — its active compounds, muscimol and ibotenic acid, are unscheduled — and Louisiana remains the only state with an outright statewide ban (with an exception for ornamental use), so amanita products can be bought and possessed in Wyoming. Two caveats matter. Food law is separate from drug law: in a December 18, 2024 alert the FDA stated that Amanita muscaria, its extracts, and constituents such as muscimol, ibotenic acid, and muscarine are not authorized for use as ingredients in conventional food, so gummies and other edible formats sit in a federal regulatory gray zone, and a growing number of states regulate amanita edibles at the retail or food-safety level without scheduling the mushroom. And pharmacologically it is not a substitute for psilocybin: fly agaric acts on a different receptor system, dosing is unpredictable, and the FDA alert followed a wave of poisonings tied to mushroom-based edibles.
Recent changes
No psilocybin or psychedelics bill was introduced in the Wyoming Legislature's 2024, 2025, or 2026 sessions, and no psilocybin ballot initiative has been filed. The closest the Legislature came to changing drug penalties at all was HB0030 (2024), a Joint Judiciary Interim Committee bill that would have based possession penalties on amount rather than the form of the substance; it failed 13-18 in the Senate Committee of the Whole on February 28, 2024, leaving the existing thresholds in place. The state's broader drug-policy posture stayed restrictive: two marijuana ballot initiatives (medical and decriminalization) failed to qualify for the 2024 ballot after falling short of Wyoming's county-distribution signature requirement, and in mid-2026 the Wyoming attorney general filed an objection that blocked the state-level rescheduling of marijuana that federal rescheduling would otherwise have triggered automatically.
Simple possession of no more than 3 ounces in plant form risks up to 12 months in jail and a $1,000 fine; exceeding that threshold is a felony of up to 5 years and a $10,000 fine, and a third or subsequent possession conviction is a felony carrying up to 5 years and a $5,000 fine. Wyoming is also one of the few states where merely being under the influence is a separate offense: W.S. 35-7-1039 makes knowingly using or being under the influence of a Schedule I, II, or III controlled substance without a practitioner's direction a misdemeanor punishable by up to 6 months in jail and a $750 fine.
Legal options for Wyoming residents
The closest genuinely legal access is Colorado, directly south, where adults 21+ can book supervised psilocybin sessions at state-licensed healing centers — the first opened in Denver in 2025, dozens were licensed by early 2026, and there is no residency requirement (the Denver area is roughly a 90-minute drive from Cheyenne). Oregon's licensed service centers are the other operating U.S. option; New Mexico's medical psilocybin program, enacted in 2025, was still being built out in mid-2026 and is not yet open to patients. Within Wyoming itself, legal purchases are limited to functional (non-psychoactive) mushrooms, amanita muscaria products, and spores intended for microscopy only.

FAQ
Are shrooms legal in Wyoming?
No. Psilocybin and psilocin are Schedule I controlled substances under the Wyoming Controlled Substances Act (W.S. 35-7-1014). Possession, cultivation, and sale are all illegal statewide in 2026, with no medical exception and no decriminalized cities.
What happens if you get caught with shrooms in Wyoming?
Possessing no more than 3 ounces of mushrooms in plant form is a misdemeanor punishable by up to 12 months in jail and a $1,000 fine. More than 3 ounces is a felony of up to 5 years and a $10,000 fine, and a third or subsequent possession conviction is a felony carrying up to 5 years and a $5,000 fine. Wyoming also criminalizes simply being under the influence of a Schedule I, II, or III drug — a separate misdemeanor carrying up to 6 months in jail and a $750 fine under W.S. 35-7-1039.
Can I get psilocybin therapy in Wyoming?
Not within the state. Wyoming has no psilocybin therapy, medical, or research-access program, and no legislation to create one has been introduced through the 2026 session. The nearest legal option is Colorado, where adults 21 and over — with no residency requirement — can book supervised sessions at state-licensed healing centers under its regulated natural medicine program; the first licensed center opened in Denver in 2025 and dozens were licensed by early 2026.
Are psilocybin spores legal in Wyoming?
Spores contain no psilocybin and are not specifically banned in Wyoming, so holding them for microscopy research sits in a legal gray zone. Other states are stricter: California, Georgia, and Idaho ban spores outright, and Florida has banned selling, transporting, importing, or giving them away since 2025. Germinating spores into mushrooms, however, is felony manufacture of a Schedule I substance in Wyoming.
