Montana’s medical cannabis industry has been operational since 2004 when voters approved I-140, or the Montana Medical Marijuana Act. Several revisions have been made to the state’s medical cannabis laws and regulations on the way, resulting in a steady medical marijuana market.
Under state law, registered Montana medical cardholders are legally allowed to name a cannabis provider and possess one ounce of usable medical cannabis. Additionally, patients who have not named a provider are allowed to possess four mature plants, four seedlings, and the amount of usable marijuana allowed by the state’s medical marijuana department.
