South Dakota Cannabis & Hemp Laws (THCA, D8, D10, HHC, THCP, THCB) — 2026 Update
Overview of South Dakota Cannabis & Hemp Laws
South Dakota has adopted one of the most restrictive approaches to intoxicating hemp cannabinoids in the Midwest. While the state allows limited medical marijuana and non-intoxicating hemp products, most alternative THC cannabinoids are prohibited from manufacture and sale.
As of 2026, Delta-8 THC, Delta-10 THC, HHC, THCP, THCB, and intoxicating THCA hemp products are illegal to manufacture or sell in South Dakota. Possession exists in a limited legal gray area, but commerce is clearly restricted.

South Dakota Hemp Law Explained
South Dakota initially adopted the federal hemp definition under the 2018 Farm Bill. However, state lawmakers later closed the loophole that allowed intoxicating hemp products.
Key Change
In 2024, South Dakota enacted legislation that prohibits the manufacture, distribution, and sale of chemically modified or intoxicating hemp-derived cannabinoids, regardless of Delta-9 THC concentration.
This approach regulates hemp based on intoxication and chemical manipulation, not just THC percentage.
