Yes, THCA is legal in Missouri under specific conditions. The 2022 Missouri Hemp Extract Registration Act permits THCA products derived from hemp with ≤0.3% THC, aligning with federal Farm Bill standards. Local enforcement by the Missouri Department of Agriculture prioritizes lab-tested, compliant products, though unregistered sales may trigger penalties.
Key Regulations for THCA in Missouri
- Hemp Source Requirement: THCA must originate from industrial hemp certified by the Missouri Department of Agriculture, verified via COA (Certificate of Analysis) showing ≤0.3% delta-9 THC.
- Product Registration: All THCA products require pre-market registration with the state, including labeling that discloses THCA content and prohibits unapproved health claims.
- Testing & Compliance: Mandatory third-party lab testing for potency, contaminants, and THC compliance; non-compliant batches face immediate seizure under 2 CSR 70-30.040(3).
Local jurisdictions, such as Kansas City and St. Louis, enforce additional zoning restrictions on THCA retailers, often limiting sales to licensed dispensaries. The 2026 Missouri Hemp Program Reauthorization introduces stricter THC concentration thresholds for smokable products, potentially reducing THCA flower availability. Producers must monitor updates from the MDA’s Hemp Program Portal to avoid enforcement actions.
