## 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):** Legale verkoop voor volwassenengebruik bestaat alleen in de staten en territoria die daadwerkelijk een recreatieve markt hebben geopend, niet in het hele land. In die rechtsgebieden kunnen toeristen meestal vanaf 21 jaar kopen bij een vergunde dispensary met een geldig door de overheid uitgegeven identiteitsbewijs of paspoort. Cannabis blijft federaal gereguleerd, dus je mag het product niet over staatsgrenzen of landsgrenzen vervoeren.

- **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.
