Cannabis in Montana

Montana voters approved I-190 in November 2020, legalizing recreational cannabis. The state leveraged its existing medical dispensary infrastructure for a smooth transition, and recreational sales launched on January 1, 2022. Montana's cannabis market is smaller and more spread out than coastal states, with dispensaries in cities like Billings, Missoula, Great Falls, Helena, and many smaller towns.
