HHC (hexahydrocannabinol) is illegal in South Dakota. HB 1125, effective July 1, 2024, makes chemical modification or conversion of industrial hemp a Class 2 misdemeanor and prohibits the sale or distribution of chemically modified hemp products. Because HHC is produced through hydrogenation of hemp-derived CBD or delta-9, every commercial HHC SKU is captured by the statute.
The Department of Health and Department of Public Safety began active retail enforcement on July 14, 2025 after a June 12, 2025 joint notice. Federal H.R. 5371 §781, effective November 12, 2026, will also exclude synthetic cannabinoids from the federal hemp definition.
