Medical cannabis
In the US state of Montana, cannabis has been legal for both medical and recreational use since January 1, 2021, when Initiative 190 went into effect. Prior to the November 2020 initiative, marijuana was illegal for recreational use starting in 1929. Medical cannabis was legalized by ballot initiative in 2004. The Montana Legislature passed a repeal to tighten Montana Medical Marijuana (MMJ) laws which were never approved by the governor. However, with the new provisions, providers could not service more than three patients. In November 2016 Bill I-182 was passed, revising the 2004 law and allowing providers to service more than three patients.
