Yes, Delta 8 THC is legal in Montana under specific conditions, but its market is tightly controlled by state and local regulations.
Delta 8 THC remains permissible in Montana as long as it is derived from hemp containing no more than 0.3% Delta 9 THC, aligning with the 2018 Farm Bill. However, the Montana Department of Public Health and Human Services (DPHHS) enforces strict labeling and testing requirements, and local jurisdictions like Missoula and Bozeman have imposed additional restrictions, including bans on Delta 8 sales in certain areas. The 2026 compliance shift requires all Delta 8 products to undergo third-party lab testing for potency and contaminants, with non-compliant items subject to seizure.
