Montana’s legal marijuana market has generated over $129 million in sales through the first five months of 2025, according to new data released by the Montana Department of Revenue.
Of the $129,013,022 sold this year, adult-use sales accounted for the majority, with over $119.6 million in revenue. Medical marijuana sales brought in an additional $9.4 million. Sales in May alone totaled more than $27.4 million, up from $26.2 million in April, and the most since October.
Montana voters approved the legalization of recreational marijuana in 2020, with licensed sales beginning in January 2022. Since then, the state has recorded a total of $1,076,931,711 in marijuana sales—$217.6 million from medical marijuana and $859.4 million from adult-use.
From these transactions, Montana has collected an estimated $180.6 million in tax revenue, with the overwhelming majority—more than $171.8 million—coming from the adult-use market. Medical marijuana, which is taxed at a lower rate, has contributed roughly $8.7 million.
Montana imposes a 20% tax on adult-use marijuana sales and a 4% tax on medical marijuana purchases. Local jurisdictions are allowed to implement an additional 3% tax, which contributes further to municipal revenues.
