The caveats that matter

  • 'THC of any type' language captures THCA-rich flower; only licensed marijuana retailers may sell it
  • Synthetic/artificially produced cannabinoids (delta-8, HHC) are banned outright
  • Compliant hemp consumables are limited to trace THC (0.5 mg/serving)

Enforcement, in practice

Montana Dept. of Revenue Cannabis Control Division publishes synthetic/intoxicating-product guidance and enforces against general retail.

Last checked 2026-08-06 — laws change. This is decision support, not legal advice.
