Montana Legal Information

In 2004, 62 percent of Montana voters passed Initiative I-148, allowing registered patients to use, possess and cultivate medical cannabis and designate a caregiver to assist them. The Montana legislature has amended that initiative in 2011, and new regulations were issued in 2011 and 2012. Currently, registered patients and their designated caregivers may possess up to one ounce of usable cannabis and cultivate up to four mature plants and 12 immature. The changes enacted by SB 423 in 2011 repealed several of the original provisions, including those concerning dispensaries and caregivers. A 2016 court ruling lifted the injunction that had preserved limited access to commercial caregivers. However, a comprehensive dispensary system was ultimately adopted by the voters of the state with the passage of I-182 in November 2016.
