Cannabis Rules & Regulations: Montana

Montana Cannabis History

As of 2021, the passage of Initiative 190 allows Montana residents age 21 and older to possess, use, and grow up to 1 ounce of marijuana.

Montana was an early adopter of medical marijuana legislation, legalizing its use by patients with debilitating medical conditions in the Montana Medical Marijuana Act and Senate Bill 423, which later replaced the voter-passed initiative with new requirements for the cultivation, manufacture, and possession of marijuana for use by people with debilitating medical conditions.
