Montana has one of the more straightforward medical marijuana programs in the country. But age requirements still confuse a lot of people, especially families seeking cannabis care for younger patients. The minimum age to get a medical marijuana card in Montana is 18 for adults applying independently. Minors under 18 can still qualify — but the process looks very different.
This guide breaks down exactly what Montana’s rules say in 2026, who qualifies, how minors can access care, and what it costs.
How Old Do You Have to Be in Montana?
Montana’s medical cannabis program is run by the Cannabis Control Division (CCD) under the Department of Revenue. The state officially requires patients to be 18 years or older to submit an adult application.
That said, age alone doesn’t disqualify a younger patient. Montana does allow minors with qualifying medical conditions to access the program — but they cannot apply on their own.
Here’s a quick breakdown of the age rules:
- 18+ → Can apply independently as an adult
- Under 18 → Requires a parent or legal guardian to act as designated purchaser (caregiver)
- Caregivers → Must be at least 21 years old to serve as a designated purchaser
So technically, there’s no minimum age floor for patients. A 5-year-old with epilepsy can be enrolled. But an adult must always manage the process and make purchases on their behalf.
What Does a Minor Need to Qualify?
The rules for minors in Montana are stricter than adult applications. Families looking to enroll a patient under 18 should be prepared for the following requirements as of 2026:
Two physician certifications are required
Unlike adults who need only one physician recommendation, minor patients must receive signed statements from two separate licensed Montana MDs or DOs. The exception is if one of those physicians is a neurologist, oncologist, or epileptologist — in that case, a second certification may not be required.
Proof of guardianship is mandatory
Parents or legal guardians must submit documentation proving their relationship to the minor. A birth certificate or court-issued guardianship document is typically accepted.
The guardian becomes the designated purchaser
The parent or guardian who applies must register as the designated purchaser and is then legally responsible for purchasing cannabis on the minor’s behalf.
A fingerprint consent form is required if cultivation is involved
If the guardian plans to grow cannabis for the minor patient at home, they must submit a Privacy Act and Consent to Fingerprint form, along with a background check through the FBI.
Qualifying Conditions for Montana Patients
Montana recognizes 13 qualifying medical conditions for its medical cannabis program in 2026. These include:
- Cancer
- Glaucoma
- HIV/AIDS
- Epilepsy or seizure disorders
- PTSD
- Severe chronic pain that interferes with daily activities
- Multiple sclerosis or spasticity
- Crohn’s disease
- Admittance to hospice care
- Several neurological disorders with chronic spasticity
Montana does not accept petitions to expand this list. Physicians can only recommend medical cannabis for conditions explicitly listed under state law.

How to Apply: Step-by-Step for Adults
Getting your medical marijuana card in Montana in 2026 involves the following steps:
- See a licensed Montana physician (MD or DO) either in-person or via telemedicine. The recommendation must be issued within 60 days of your application.
- Gather your documents: proof of Montana residency (driver’s license, state ID, tribal ID, voter registration), a passport-style photo, and your physician’s signed statement.
- Log in to Montana’s TransAction Portal (TAP) and complete your application online. All applications must go through
- TAP — paper submissions are not accepted.
- Pay the $20 non-refundable application fee via credit, debit, or ACH.
- Print your temporary card immediately after submission. Your permanent card is typically mailed within 30 days.
The card is valid for up to one year from the date of approval.
What About Minors — How Does the Application Work?
For patients under 18, the application process goes through TAP as well, but the guardian fills out the Minor Application instead of the Adult Application.
The parent or guardian must:
- Provide two physician statements (unless an exemption applies)
- Upload proof of legal guardianship or a birth certificate
- Complete caregiver registration through the same portal
- Submit a fingerprint consent form if they plan to cultivate cannabis for the minor
Minor patients receive a card just like adults, though the guardian’s name will also appear in the registry.
Benefits of Getting a Montana Medical Card
Even though recreational cannabis is legal in Montana for adults 21 and older, having a medical marijuana card comes with real advantages:
- Lower tax rate: Medical patients pay 4% sales tax on cannabis. Recreational users pay 20% — a major difference over time.
- Higher purchase limits: Cardholders can buy up to 1 ounce per day and 5 ounces per month. Recreational buyers are capped at 1 ounce per transaction.
- Home cultivation rights: Medical patients can grow 4 mature plants and 4 seedlings at home. Recreational users are limited to 2 mature plants.
- Access for patients under 21: Adults aged 18–20 cannot legally buy recreational cannabis but can purchase medical cannabis with a valid card.
- Legal protections: Registered patients have additional protections under state law.
What Does a Medical Marijuana Card Cost in Montana?
The state application fee is just $20, paid through TAP. This fee is non-refundable.
However, you’ll also need to factor in the cost of a physician consultation. Telemedicine visits for medical cannabis certification in Montana typically range from $75 to $150, depending on the provider. Some services offer same-day appointments.

Can Out-of-State Cardholders Use Their Card in Montana?
Montana does not offer reciprocity for visiting medical marijuana patients. If you hold a card from another state, you cannot use it at Montana dispensaries for medical cannabis.
However, visitors aged 21 and older can still purchase recreational cannabis in counties that have opted in to adult-use sales.
