Effective Total
20% (no additional state sales tax — Montana has no general sales tax)
Montana imposes a 20% excise tax on adult-use cannabis retail sales. The state has no general sales tax, so the 20% is the total state-level tax burden. Local option taxes of up to 3% are permitted. Medical cannabis is taxed at 4%. Revenue is distributed: 10.5% to general fund, 4.5% to counties/municipalities, and remainder to conservation, substance abuse, and veteran services.

Key Statutes
I-190 — Montana Marijuana Regulation and Taxation Act
Mont. Code Ann. § 16-12-101 et seq.Passed by voters in November 2020 with 57% approval. Legalized recreational cannabis for adults 21+, established the 20% excise tax, and allowed local governments to opt out. Adult-use sales began January 1, 2022.
CI-118 — Constitutional Amendment for Minimum Age
Mont. Const. Art. II (amendment)Companion ballot measure to I-190. Amended the Montana Constitution to set the legal purchase and possession age at 21. Passed alongside I-190 in November 2020.
HB 701 — Implementation Legislation
Mont. Code Ann. § 16-12-201 et seq.The 2021 legislature passed HB 701 to implement I-190, establishing the licensing framework, tax structure, and regulatory details. Gave existing medical providers priority for adult-use licenses and allowed counties to opt out of adult-use sales.
For Operators
Small state, real distances
Montana has about 1.1 million people spread across the fourth-largest state by area. That geography defines everything about this market. Transport costs are significant. Customer density is low outside Billings, Missoula, Great Falls, and Bozeman. The dispensaries that do well here serve as destination stops for entire regions — not walk-in traffic from foot traffic.
County opt-outs fragment the map
HB 701 gave counties the right to opt out of adult-use sales. Several rural counties exercised that option. The result is a patchwork: you might drive through two dry counties between dispensary visits. Operators need to understand the specific regulatory status of every county where they plan to operate or serve customers.
Low fees, moderate tax
Montana licensing fees are among the lowest in the country — $1,000 application fees across most categories. The 20% excise is moderate, and the absence of a general state sales tax means consumers pay 20% total (plus potential 3% local). Margins can work here if you keep overhead tight. The challenge is volume, not regulation.
For Consumers
Buying cannabis in Montana
Adults 21+ can buy up to 1 ounce of flower per transaction from any licensed dispensary. Bring a valid ID — Montana dispensaries are strict about verification. Product selection varies by location. The stores in Billings and Missoula carry the widest variety. Smaller-town dispensaries may have limited stock.
Home growing
Montana allows adults to grow up to 2 mature and 2 seedling plants per person at home. The plants must be in a locked, enclosed area not accessible to anyone under 21. That's a smaller home grow allowance than most legal states, but it's enough for personal use if you know what you're doing.
Check the county rules
Not every Montana county allows recreational cannabis sales. Some opted out under HB 701. Before making a trip to buy, check whether dispensaries in your destination county serve adult-use customers or medical only. The DOR maintains a licensee search tool online.
