Wyoming Cannabis & Hemp Laws (THCA, D8, D10, HHC, THCP, THCB) — 2026 Update
Overview of Wyoming Cannabis & Hemp Laws
Wyoming maintains one of the strictest cannabinoid regulatory environments in the United States. While hemp cultivation is allowed under federal guidelines, Wyoming has taken decisive action against intoxicating hemp-derived cannabinoids.
As of 2026, most THC-adjacent compounds are illegal to manufacture, sell, or distribute in Wyoming, even if they are derived from hemp.
Marijuana Law in Wyoming (2026)
- Recreational marijuana: Illegal
- Medical marijuana: Illegal
- THC flower and concentrates: Illegal
- Home cultivation: Illegal
- Enforcement authority: Wyoming Attorney General and local law enforcement
Wyoming does not operate a medical marijuana program, and possession of marijuana remains a criminal offense under state law.
Wyoming Hemp Law Explained
Wyoming allows hemp under the 2018 Federal Farm Bill, but with important state-level restrictions:
- Hemp must contain no more than 0.3% Delta-9 THC by dry weight
- Intoxicating hemp derivatives are prohibited
- Chemical conversion of cannabinoids is tightly regulated
In 2023, Wyoming enacted legislation that explicitly banned Delta-8 THC and similar compounds, signaling a zero-tolerance approach to intoxicating hemp products.

Conclusion: Wyoming’s Zero-Tolerance Approach in 2026
Wyoming enforces one of the most restrictive cannabis and hemp frameworks in the country. While industrial hemp remains legal, nearly all intoxicating hemp-derived cannabinoids are banned, regardless of federal hemp definitions.
Consumers should avoid THC-adjacent products entirely, and businesses should not attempt retail sales of Delta-8-style cannabinoids within the state. Until legislative reform occurs, Wyoming remains a no-go zone for modern hemp cannabinoids.
