Montana legalized recreational marijuana in the November 2020 election, with the passing of the Marijuana Legalization Initiative, I-190. Dispensaries are not yet operational. While a detailed timeline is still unknown, I-190 mandates that the state must begin accepting licenses no later than January 1, 2022. Expect some time before dispensaries are open.

Montana made its first steps towards becoming a medicinal marijuana state in 2004 with the voter approval of I-140, or the Montana Medical Marijuana Act (pdf). The state has seen a series of legal challenges to the program, but those ultimately failed, resulting in a steady medical market today.

Possession

I-190 allows adults 21 an older to possess up to 1 ounce of cannabis or 8 grams of concentrate.

As of June 30, 2017, registered cardholders who named a provider are allowed to possess up to one ounce of usable medical cannabis. A registered cardholder who has not named a provider may possess up to four mature plants, four seedlings, and the amount of usable marijuana allowed by the department.

If two or more registered cardholders share a residence and have not named providers, they can have up to eight mature plants, eight seedlings, and the amount of usable marijuana allowed by the department.

Any cardholder who possesses mature plants or seedlings must alert the department of the plants' and seedlings' location. .

Purchasing Limits

Montana has not yet specifically established purchasing limits for recreational marijuana, however, it is expected to match the state limit of possession at 1 ounce of flower or 8 grams of concentrate.

According to the state's official website, medical marijuana cardholders who have named a provider can purchase up to one ounce of retail marijuana flower or its equivalent in concentrates or edibles. After the passing of SB265, medical patients may purchase up to 5 ounces a month, and no more than 1 ounce a day.Where to Buy

Qualifying Patients

According to Senate Bill No. 333, patients with a "debilitating medical condition" can qualify for a license. Those medical conditions are listed as:

Qualifying Medical Cannabis Conditions

  • Admittance into hospice care in accordance with department rules
  • Cachexia or wasting syndrome
  • Cancer
  • Central nervous system disorder resulting in chronic, painful spasticity or muscle spasms
  • Crohn's disease

Consumption

Both medical and recreational marijuana can only be consumed on private property away from public view.

Driving Under the Influence

It is illegal to consuming marijuana or being under the influence while driving, flying an aircraft, or boating.

Transporting and Exporting Marijuana

Registered medical patients are allowed to transport their medicinal cannabis as needed so long as it is not accessed by anyone in the vehicle. While it’s legal to transport medical cannabis in the state (for example, driving home after a purchase at a dispensary) transporting and exporting cannabis of any kind across state lines remains a federal offense

Cultivation

I-190 allows Montana residents aged 21 and older to grow no more than four marijuana plants and four seedlings for personal use in their residence, as long as the plants are within an enclosed area with a lock and beyond public view.

Medical patients who have not named a provider can cultivate up to four seedlings and four mature plants – with one ounce of usable medicinal marijuana at any time. Patients who have designated a provider are not allowed to grow their own medicinal marijuana. Explore Strains

Delivery

Montana's cannabis regulations do not allow delivery.
