5 Montana Cannabis Laws You Must Know

Montana has a long history of legal cannabis, starting in 2004 with medical. But then years of back-and-forth made medical marijuana harder to get.

In 2020, voters approved Montana I-190 to legalize recreational cannabis. The state legislature then passed House Bill 701 in April 2021 which altered several aspects of the voter-approved measure. Under HB 701, the recreational law “Montana Marijuan Regulation and Taxation Act” became effective on January 1, 2022.

    • Registered medical marijuana cardholders can purchase and possess up to one ounce of marijuana flower, or its equivalents.

    • Medical marijuana purchases are taxed at 4% of retail sales, and recreational purchases are taxed at 20% of retail sales.
    • Local jurisdictions can add an additional tax of no more than 3%.

How do patients get into the medical marijuana program?

  • Residents may register with the program after obtaining a recommendation from a licensed physician. The recommendation — along with an application and a $5.00 fee — is submitted to the state’s regulatory agency, the Department Public Health and Human Services. The registration must be renewed every 12 months.

Which medical conditions qualify?

  • Cancer, glaucoma, positive status for HIV/AIDS, cachexia or wasting syndrome, intractable nausea or vomiting, epilepsy or an intractable seizure disorder, multiple sclerosis, Crohn’s disease, painful peripheral neuropathy, a central nervous system disorder resulting in chronic, painful spasticity or muscle spasms, admittance into hospice care, or any other medical condition or treatment for a medical condition approved by the legislature. Severe chronic pain is also included, and requires either proof in the form of lab tests or imaging, or a second opinion by another physician. Post- traumatic stress disorder was added in the 2016 voter initiative, I-182.

How do patients obtain medical marijuana?

  • Patients may either grow their own medical marijuana, or obtain it through a provider. Patients designate their preference when they apply to be in the registry.

How much medical marijuana can a patient have?

  • Patients may possess up to 1 ounce of usable marijuana. State courts have interpreted “usable marijuana” to be limited to raw cannabis plant material. Extracts and concentrates, and the food items made from them, are not protected under current law.

How many plants can a patient or provider grow?

  • A patient who has authorization to grow may have up to 12 “seedlings,” and up to 4 mature plants. A seedling is defined as a marijuana plant that is less than 12 inches tall or wide. A “mature” plant is any plant that is larger that that. Providers may have up to 12 seedlings and up to 4 mature plants for each patient they serve.

Does Montana have reciprocity?

  • No. Only patients who are registered in the state program are legally protected under the medical marijuana laws.

What changed under I-182, the 2016 voter initiative?

  • Under the previous law, providers could serve a maximum of three patients. The voter initiative removed that limitation, although questions remain about when the change goes into effect.
  • Post-traumatic stress disorder was added as a qualifying medical condition.
  • The state medical board is no longer required to investigate doctors who recommend medical marijuana to 25 patients or more.
  • Medical marijuana may be tested for potency and for the presence of contaminants.
  • Businesses must be licensed and inspected by the state.
  • Businesses no longer need to be owned by residents to be licensed.
  • Employees working for providers are protected from criminal possession laws.

Dispensary licensing explained:

  • The Montana Department of Revenue controls the licensing of medical marijuana providers and dispensaries in Montana (this used to be handled by the Department of Public Health and Human Services).
  • The adult-use program is a separate Department of Revenue program.
  • Here’s what you need to know to get licensed in Montana:
  • Any medical dispensary licensed prior to November 2020, who is also in good standing with the state, can apply for a recreational license. Good standing refers to no infractions by state inspectors and also paid to date on state, personal, MJ, and income taxes.
  • The fee for an adult-use or medical marijuana dispensary license is $5,000 per location.
  • Dispensaries can’t be located within a city, town, or country that prohibits medical marijuana use, or within 500 feet of any place of worship, school, or post-secondary school.

Purchase and possession limits

  • Registered medical marijuana patients and adult-use consumers can purchase and possess up to one ounce of marijuana flower, or its equivalents:
  • Eight grams of marijuana concentrate
  • 800 milligrams of THC-infused products or edibles
  • 8 grams or 8ml of THC in marijuana concentrate
  • Medical patients can purchase 5 ounces per month with a daily purchase limit of one ounce.
  • Recreational cannabis users can cultivate up to two mature marijuana plants and two seedlings in a private, locked area out of public view. Medical marijuana cardholders can cultivate up to four mature plants and four seedlings, also in a private, locked area out of public view
  • For adult-use consumers, marijuana products sold at a dispensary are regulated and sold on the basis of the concentration of the THC. An individual package is limited to:
  • For marijuana sold as flower, 1 ounce of usable marijuana. The total potential psychoactive THC of marijuana flower may not exceed 35%.
  • For capsules – no more than 100 milligrams of THC per capsule and no more than 800 milligrams of THC per package.
  • For tincture – no more than 800 milligrams of THC.
  • For edibles or a food product – no more than 100 milligrams of THC. A single serving of an edible marijuana product may not exceed 10 milligrams of THC.
  • For a topical product – a concentration of no more than 6% THC and no more than 800 milligrams of THC per package.
  • For suppository or transdermal patch – no more than 100 milligrams of THC per suppository or transdermal patch and no more than 800 milligrams of THC per package.
  • Any other marijuana product – no more than 800 milligrams of THC.
  • A registered cardholder may purchase or possess any combination of marijuana flower, marijuana-infused products, and marijuana concentrate if the total calculated conversion is equal to or less than the legal purchase or possession amount.

Packaging and labels

Dispensary packaging explained:

Cannabis labels must include the following information:

  • Strain name
  • The common or usual name of the marijuana product (e.g., flower, inhaled extract, edible, cookie, or drinkable, topical, transdermal patch)
  • The name of the marijuana dispensary that sold the product and the license number or numbers of the cultivator and manufacturer, as applicable
  • The unique identification number generated from the seed-to-sale tracking system
  • Date of harvest for marijuana flower or date of manufacture for marijuana products
  • The net quantity of contents of the marijuana product.
  • In addition to weight or fluid measure, a licensee shall include the number of servings in the net quantity of contents statement if the product is a multi- serving marijuana product
  • The following statement: “This product has been tested and meets the requirements of the state of Montana.”
  • A QR code that links to the product’s certificate of analysis with a statement informing customers they can scan the code to see additional product information;’
  • The universal symbol, available from the department’s website.
  • All marijuana and marijuana products shall be labeled with the following warnings:
  • “Keep out of reach of children and pets”
  • “This product may be addictive”

  • Marijuana products for final sale must be packaged in child-resistant containers.


Explained: Here are the basics of cannabis taxation in Montana:

  • Medical marijuana purchases are taxed at 4% of retail sales.
  • Adult-use cannabis is taxed at 20% of retail sales.
  • Local jurisdictions can add an additional tax of no more than 3%.

Conditional Release

  • The state allows conditional release or alternative or diversion sentencing for people facing their first prosecutions. Usually, conditional release lets a person opt for probation rather than trial. After successfully completing probation, the individual’s criminal record does not reflect the charge.

Drugged Driving

  • Every state criminalizes driving under the influence of a controlled substance. Some jurisdictions also impose additional per se laws. In their strictest form, these laws forbid drivers from operating a motor vehicle if they have a detectable level of an illicit drug or drug metabolite (i.e., compounds produced from chemical changes of a drug in the body, but not necessarily psychoactive themselves) present in their bodily fluids above a specific, state-imposed threshold. Read further information about cannabinoids and their impact on psychomotor performance. Additional information regarding cannabinoids and proposed per se limits is available online.


  • Generally, legalization means a policy that supports a legally controlled market for marijuana, where consumers can buy marijuana for personal use from a safe legal source.

Local Decriminalization

  • This state has local jurisdictions that have enacted municipal laws or resolutions either fully or partially decriminalizing minor cannabis possession offenses.

Mandatory Minimum Sentence

  • When someone is convicted of an offense punishable by a mandatory minimum sentence, the judge must sentence the defendant to the mandatory minimum sentence or to a higher sentence. The judge has no power to sentence the defendant to less time than the mandatory minimum. A prisoner serving an MMS for a federal offense and for most state offenses will not be eligible for parole. Even peaceful marijuana smokers sentenced to “life MMS” must serve a life sentence with no chance of parole.

Medical Marijuana

  • This state has medical marijuana laws enacted. Modern research suggests that cannabis is a valuable aid in the treatment of a wide range of clinical applications. These include pain relief, nausea, spasticity, glaucoma, and movement disorders. Marijuana is also a powerful appetite stimulant and emerging research suggests that marijuana’s medicinal properties may protect the body against some types of malignant tumors, and are neuroprotective.
