Marijuana laws in Wyoming
Wyoming has not legalized adult-use or medical marijuana. Practitioners may not dispense or prescribe marijuana, tetrahydrocannabinol, or synthetic equivalents unless the product is an FDA-approved drug, such as dronabinol. A former supervised hemp-extract program, W.S. 35-7-1901 through 35-7-1903, was repealed in 2019.
Under W.S. 35-7-1031(c), unauthorized possession of a controlled substance in plant form of no more than three ounces is a misdemeanor punishable by up to 12 months in jail, a fine of up to $1,000, or both. A third or subsequent offense under that paragraph can bring up to five years and a fine of up to $5,000. Manufacture or delivery of a Schedule I substance that is not a narcotic drug can bring up to 10 years and a $10,000 fine.
House Bill 166 in the 2026 session, a proposal related to marijuana scheduling, did not become law. Hemp that meets the agricultural hemp definition is regulated separately.
Marijuana remains illegal under federal law, and Wyoming has no state medical marijuana license.

Products sold as delta-8 or THCA may still be treated as marijuana or THC if they fall outside the hemp definition. Separately, a stricter federal hemp definition, with a total-THC standard that counts THCA and a 0.4 mg-per-container cap, takes effect December 11, 2026.

State law does not change federal rules on federal land, on carrying marijuana across state lines, or on federally required drug testing, such as for DOT-regulated jobs.
