## Facts

- **Catalogue content updated:** 2026-10-22
- **Legal status:** Allowed with conditions. Adults 21+ may buy from licensed adult-use dispensaries in counties that allow them ("green" counties); up to 1 ounce of flower, 8 g of concentrate or 800 mg of THC in infused products per purchase. Conditions: Minimum age 21+. Rule jurisdiction: Montana. Reviewed: 2026-09-09.
- **Can tourists buy:** Allowed with conditions. Visitors buy on the same terms as residents: any adult 21+ with a valid government-issued photo ID may purchase from a licensed retailer; there is no residency requirement. Some counties ("red" counties) do not allow adult-use sales — check where you are. Conditions: Minimum age 21+. Rule jurisdiction: Montana. Reviewed: 2026-09-09.
- **Overview of United States (not a local permission):** Легальний adult-use продаж існує лише у штатах і територіях, де recreational-ринок реально запущено, а не по всій країні. У таких юрисдикціях туристи зазвичай можуть купувати в ліцензованому dispensary з 21 року з чинним державним посвідченням особи або паспортом. Канабіс залишається під федеральним контролем, тому продукт не можна перевозити між штатами чи через міжнародні кордони.

- **Medical access:** Allowed with conditions. Montana's medical marijuana program (registered cardholders) continues with higher limits and no county opt-out. Conditions: Minimum age 18+. Rule jurisdiction: Montana. Reviewed: 2026-09-09.
- **Possession limit:** Allowed with conditions. Adults 21+ may possess up to 1 ounce of usable marijuana (or 8 g of concentrate, or 800 mg of THC in infused products) and grow 2 mature plants and 2 seedlings at a private residence, out of public view. Conditions: Minimum age 21+. Rule jurisdiction: Montana. Reviewed: 2026-09-09.

- **Important restrictions:** Cannabis may not be taken across a state line — that remains a federal offence.
