For years, Montana has been an oasis for marijuana lovers in the northwest half of the United States. Unless you get past Idaho or head east to Minnesota, you’re somewhat in a weed dead zone. Now, Montana has taken even more steps to bring marijuana to the region.
In November 2020, Montana voters approved Initiatives 190 and 118 making it legal for adults to purchase, possess, consume, and grow cannabis. House Bill (HB) 701 was signed into law in May 2021 legalizing adult-use marijuana.
