No, THCA remains illegal in South Dakota under state narcotics laws, which classify all tetrahydrocannabinol isomers—including THCA—as controlled substances. The South Dakota Department of Public Safety enforces these prohibitions, aligning with the state’s strict 2026 compliance framework for cannabis derivatives.
Key Regulations for THCA in South Dakota
- Controlled Substance Classification: THCA is explicitly listed as a Schedule I controlled substance under South Dakota Codified Laws § 34-20B-1, mirroring federal analog enforcement.
- Zero-Tolerance Policy: The South Dakota Attorney General’s 2025 guidance confirms that even trace amounts of THCA in hemp-derived products violate state law, overriding federal Farm Bill protections.
- Enforcement Priorities: Local law enforcement, in coordination with the South Dakota Division of Criminal Investigation, prioritizes interdiction of THCA products, particularly those marketed as “legal hemp” despite psychoactive potential.
