The issue's old revenue.mt.gov PDF returned 404. Read [ARM 42.39.118(2), LII republication](https://www.law.cornell.edu/regulations/montana/Mont-Admin-r-42.39.118): 1 oz flower = 8 g/8 mL concentrate = 800 mg product THC, with combinations calculated together. The official rules gateway was unavailable; do not cite the unadopted 2022 proposal as final law.

+Possession and gifts use product-specific equivalents. The statute's civil ranges are STRICTLY above 1 oz and below 2 oz, or above 8 g and below 16 g concentrate. It gives forfeiture plus the person's choice of fine/community service, with increased repeat maxima. Do not include exactly 2 oz/16 g in those civil bands or invent an edible civil-equivalence band absent from subsection (7). Other unauthorised possession can fall under §45-9-102 (five years/$5,000/both, first-offence deferred-sentence presumption). Preserve lawful crop storage, medical allowances and the resident home-grow qualification from #149. Scores stay 5/3/6/5/3/6; this corrects existing conditions, not a new 2026 change.
