Arkansas Cannabis & Hemp Laws (THCA, D8, D10, HHC, THCP, THCB) — 2026 Update
Arkansas operates a medical marijuana program and allows industrial hemp, but the state has taken a firm stance against intoxicating hemp-derived cannabinoids. As of 2026, Arkansas law focuses on psychoactive effects and chemical structure, not marketing labels or hemp origin.
This guide explains what’s legal, what’s restricted, and what’s prohibited in Arkansas, covering the cannabinoids consumers and retailers most often ask about.
Arkansas Cannabis & Hemp Law Overview (2026)
Arkansas regulates cannabinoids through two separate legal frameworks:
- Medical marijuana — legal only through licensed dispensaries
- Industrial hemp — allowed only for non-intoxicating products
Arkansas does not permit the sale of intoxicating THC isomers to be sold as hemp products, even if they meet federal Delta-9 THC limits.
Key Legal Principles
- Hemp must contain 0.3% or less Delta-9 THC
- Intoxicating THC isomers are prohibited
- Chemical conversion of cannabinoids is closely regulated
- Psychoactive THC is restricted to the medical marijuana system

Conclusion: Arkansas’s Cannabis & Hemp Reality in 2026
Arkansas has taken a clear and conservative approach to cannabinoid regulation. While the state supports medical marijuana and industrial hemp, it has firmly rejected intoxicating hemp-derived THC alternatives.
In 2026, THCA, Delta-8, Delta-10, HHC, THCP, and THCB are legal in Arkansas only within the state’s medical marijuana program—or not at all. Hemp-derived THC substitutes are not compliant with Arkansas law.
For consumers and businesses, the takeaway is simple: if it causes intoxication, it belongs in the medical cannabis system—not the hemp market.
