Wyoming
Cannabis Laws 2026
FULLY ILLEGAL
Wyoming maintains one of the strictest cannabis prohibition frameworks in the nation as of 2026. There is no adult-use market, no medical program, and no decriminalization framework anywhere in the state. Wyoming is one of only a handful of states that has made no meaningful movement toward any form of cannabis legalization or reform. The Wyoming Legislature has consistently rejected all cannabis bills — medical, decriminalization, and adult-use alike — making Wyoming one of the most resistant states to reform in the entire country.
FULLY ILLEGAL
Possession
Possession of any amount of cannabis in Wyoming is a criminal offense with zero exceptions. Possession of 3 ounces or less is a misdemeanor carrying up to 12 months in jail and a $1,000 fine for a first offense. Possession of more than 3 ounces carries felony charges with up to 5 years in prison and a $10,000 fine. Wyoming has no decriminalization framework, no civil penalty tier, and no medical exemption of any kind. There are no municipal ordinances reducing penalties anywhere in the state — Wyoming enforces prohibition uniformly statewide.
EMPLOYMENT
Your Job
Wyoming provides zero employment protections for cannabis users of any kind. Employers may test, discipline, and terminate employees for any positive cannabis result with no restrictions. No state law limits an employer's right to enforce a zero-tolerance drug-free workplace policy. Out-of-state medical cards carry absolutely no legal recognition or protection in Wyoming. Wyoming's significant energy sector workforce — oil, gas, and coal — operates under strict federal contractor and safety-sensitive drug testing standards making zero-tolerance enforcement near-universal statewide.
USAGE
Where You Can Use It
There is no legal location to consume cannabis anywhere in Wyoming — public or private. No dispensaries exist, no consumption establishments are permitted, and private residential use carries the same criminal penalties as public possession. Wyoming has passed no CBD-specific legislation beyond federal hemp law — making it one of the most restrictive states even for low-THC products. All cannabis products carry criminal penalties under Wyoming Statutes Title 35. No municipal exceptions or local ordinances reduce penalties anywhere in the state.
DRIVING
Driving
Driving under the influence of cannabis is illegal in Wyoming. The state enforces a zero-tolerance per se standard — any detectable amount of THC in a driver's blood is a prosecutable DUI offense under Wyoming Statutes § 31-5-233. Law enforcement uses field sobriety testing and blood draws to establish per se violations. A first DUI offense carries fines of $750 minimum, license suspension of 90 days, and up to 6 months in jail. Wyoming's vast highway network and active law enforcement presence on I-25, I-80, and I-90 make it a high-risk transit corridor for cannabis transport.
TRAVELING
Traveling
Wyoming borders Colorado to the south and Montana to the north — both legal adult-use states — making its northern and southern borders active enforcement zones for cannabis transport. Transporting any amount of cannabis across any state line into Wyoming is a state and federal felony regardless of where it was legally purchased. I-25 and I-80 are among the most actively patrolled interstate corridors for cannabis interdiction in the Rocky Mountain region. Out-of-state medical cards provide zero protection in Wyoming under any circumstances. No exceptions exist for any quantity or form of cannabis.
Enforcement and Compliance
Wyoming law enforcement actively enforces all cannabis statutes under Title 35 with no exceptions for medical necessity, out-of-state patient status, or quantity. Wyoming has no automatic expungement pathway for cannabis offenses and no diversion or deferred prosecution programs specific to cannabis cases. The state's geographic position between Colorado and Montana — both legal adult-use states — makes it a high-priority cannabis interdiction zone with active law enforcement operations on all major interstate corridors. Wyoming's felony possession threshold of just over 3 ounces is among the lowest in the nation.
2026 Legislative Status
As of June 2026, Wyoming stands as one of the last true holdout states on cannabis reform. The Wyoming Legislature has rejected every cannabis bill introduced in recent sessions — including medical cannabis, CBD expansion, decriminalization, and adult-use proposals. No ballot initiative pathway exists in Wyoming — all reform must pass through the legislature — and the political environment in Cheyenne remains firmly opposed to any form of legalization. Wyoming is now one of only three or four states with no form of cannabis access whatsoever and no realistic near-term path to reform.
PROHIBITED
Home cultivation of cannabis is a felony in Wyoming regardless of quantity or stated purpose. Growing even a single plant is prosecuted under Title 35 and carries significant criminal penalties. Cultivation of any amount carries felony charges with prison sentences and fines based on plant count and weight. There are no medical exemptions, caregiver provisions, or personal use exceptions of any kind recognized under Wyoming law.
Home Cultivation
NOT RECOGNIZED
Out-of-State Reciprocity
Wyoming does not recognize medical cannabis cards issued by any other U.S. state or territory. Out-of-state patients have zero legal protection in Wyoming and are subject to the same criminal penalties as any Wyoming resident. There is no reciprocity program, no visitor card pathway, and no pending legislation that would establish any form of out-of-state recognition under Wyoming law. Visitors from neighboring Colorado and Montana must leave all cannabis behind before crossing into Wyoming — no exceptions.
