Montana Medical Marijuana Card Guide: Documents, Application & Renewal

Getting a medical marijuana card in Montana is a two-step process. First, a Montana-licensed physician provides a signed statement confirming you have a qualifying condition. Then you apply online through the Department of Revenue’s TransAction Portal (TAP), upload your documents, and pay the state fee. You can print a temporary card from TAP right away, and your official card is mailed to you. This guide walks you through both steps.

2 documents needed to apply for a Montana medical marijuana card

You’ll need to provide the following to apply for a medical marijuana card in Montana:

Physician’s Statement A signed statement (written certification) from a Montana-licensed Medical Doctor (MD) or Doctor of Osteopathy (DO) with a bona fide relationship with you, dated within 60 days of your application. You will receive your certification once approved by a Kif Doctors provider.

Proof of Identity & Residency Only Montana residents qualify. A Montana driver’s license, Montana state or tribal ID, voter registration, or a Montana hunting or fishing license works.

The state application fee is $20 annually (a replacement card costs $10).

Your physician’s statement must be dated within 60 days of your application submission, so don’t delay. Here’s a guide on exactly what you need to do next!

Before you start, have these supporting documents ready:

Kif Doctors Physician’s Statement This must be signed by a Montana-licensed MD or DO and dated within 60 days of submission

Proof of Identity / Residency (required)

• Montana driver’s license, Montana state or tribal ID, voter registration, or Montana hunting/fishing license

Optional – petition to increase your monthly limit

• A Cardholder Petition for Exception to Monthly Purchase Limits (to raise the limit from 5 to 8 ounces), signed by the same physician

• Proof of property ownership, or written permission from the property owner where you’ll cultivate

A payment method for the $20 application fee (paid through TAP)

Getting Your Montana Medical Marijuana Card

The Montana application is completed online through the TransAction Portal (TAP).

1. Consult a Montana-licensed physician. Speak with a Kif Doctors provider — an MD or DO with an established office in Montana. Certification can be done by telemedicine or in person.
2. Get certified. If you have one of Montana’s qualifying conditions, your physician completes and signs your statement.
3. Log in to TAP. Go to the TransAction Portal, find the Cannabis Control Card section, and select “Apply for or Manage a New Medical Marijuana Card.” Choose Adult Application (or Minor Application).
4. Complete your application. Enter your personal information.
5. Upload your documents. Attach your physician’s statement, proof of residency, and your passport-style photo. Add any petition or cultivation documents if applicable.
6. Pay the fee. Submit the $20 fee through TAP.
7. Print your temporary card. After submitting, you’ll have access to a temporary card to print from TAP — you must carry a physical copy to use it.
8. Receive your official card. The Cannabis Control Division reviews your application and mails your registry identification card, typically within about 30 days.
9. Purchase marijuana. Present your card at any licensed Montana dispensary.

Please note: Approved cards are valid for up to one year from the approval date (or a shorter period if your physician specifies). Registered medical patients enjoy benefits adult-use customers don’t, including a much lower tax rate, higher purchase limits, cultivation rights, access at age 18, and legal protections.

How to renew your Montana medical marijuana card

It’s quick and easy to renew your Montana medical marijuana card with Kif Doctors. Here’s what you’ll need to do:

1. Sign in to your Kif Doctors account or register as a renewal patient.
2. Speak to a Montana-licensed MD or DO (telehealth is available) to get a new physician’s statement.
3. Get your complete, signed physician’s statement (dated within 60 days).
4. Log into TAP, go to the Cannabis Control Card section, select “Apply for or Manage a New Medical Marijuana Card,” then “Renew an Existing Card” (Adult or Minor Application).
5. Complete your renewal, upload your documents, and pay the $20 fee.
6. Print your temporary card and receive your new card by mail.

The state recommends submitting renewals at least 30 days before your card expires, and you must complete the state application within 60 days of your physician’s renewal approval.

Next steps after renewal

After receiving your renewed Kif Doctors statement, complete your renewal through the TransAction Portal.

Here’s a guide on what to do next.

Renewing Your Montana Medical Marijuana Card

1. Renew your physician’s statement with your Kif Doctors provider (dated within 60 days).
2. Log in to TAP and open the Cannabis Control Card section.
3. Select “Renew an Existing Card” and choose Adult or Minor Application.
4. Verify and update your personal information.
5. Upload your new physician’s statement, proof of residency, and photo.
6. Pay the $20 fee and submit.
7. Print your temporary card; your renewed card arrives by mail.

Please note: Submit early (at least 30 days before expiration) so your access isn’t interrupted. For a minor renewal, the designated purchaser must remain active and the required minor documentation must be resubmitted.

Legal limitations for cardholders

Montana’s medical marijuana program operates under the Montana Medical Marijuana Act and is administered by the Cannabis Control Division within the Department of Revenue. Adult-use cannabis was legalized in 2020, with sales beginning in 2022.

Registered cardholders may purchase up to 1 ounce of flower per day and up to 5 ounces of flower per month (with a petition available to increase the monthly limit to 8 ounces). Per transaction, you may purchase up to one ounce of flower or its equivalent (such as 8 grams of concentrate or 800 mg of THC in infused products).

Under Montana medical marijuana law, registered cardholders generally have the right to:

• Be certified for one of the state’s qualifying conditions (such as cancer, glaucoma, HIV/AIDS, epilepsy, severe chronic pain, intractable nausea, cachexia, a central nervous system disorder causing chronic painful spasticity or muscle spasms, PTSD, Crohn’s disease, painful peripheral neuropathy, or admittance to hospice care) and purchase from any licensed dispensary at age 18 or older.
• Pay a much lower tax rate — medical marijuana is taxed by the state at 4%, compared with the higher adult-use rate (counties may add a local tax of up to 3% on either).
• Cultivate cannabis at home if you own the property or have written permission from the property owner where you’ll grow.
• Designate up to two individuals as designated purchasers to buy medical marijuana on your behalf.

However, a Montana medical marijuana card does not necessarily give you the right to:

• Obtain a card while in the custody of the Department of Corrections or youth court — this renders a registration invalid.
• Possess more than the legal per-transaction or monthly limits.
• Use cannabis in public places, in a vehicle, or anywhere prohibited by law.
• Use or possess cannabis at your place of employment without recourse — Montana law does not provide explicit employment protections, so employers may set their own policies.
• Work, live, or learn somewhere that could lose a monetary or licensing benefit under federal law due to your patient status. Some federal jobs and positions requiring a commercial driver’s license may conflict with federal law.
• Sell or distribute cannabis to others.
• Drive or operate a vehicle while under the influence of cannabis.
• Own a firearm — federal law prohibits possession of firearms by individuals who use marijuana, including medical patients.

Montana maintains a closed list of qualifying conditions and does not accept petitions to add new ones; physicians can only recommend for the listed conditions. Recreational adult-use cannabis is legal for those 21 and older, but only Montana residents may apply as medical patients. Insurance does not cover medical cannabis.

How to become a designated purchaser (caregiver) in Montana

In Montana, the person who buys medical marijuana on a patient’s behalf is called a designated purchaser. A cardholder may designate up to two designated purchasers.

To act as a designated purchaser, you generally must:

• Be at least 21 years old.
• Be registered by the patient — the cardholder lists you (with your date of birth) during their application or renewal, or after they receive their card.

For a minor patient, the designated purchaser must be the patient’s parent or legal guardian and at least 21 years old. If a guardian will cultivate marijuana for the minor, a Consent to Fingerprint Form and an FBI background check are required.

Minor patient information

Minors (anyone under 18) face additional requirements. The minor’s physician statement must be signed by two physicians, unless the treating or referral physician is an oncologist, neurologist, or epileptologist (in which case one is sufficient). The custodial parent or legal guardian must consent in writing, provide documentation of legal guardianship (such as a birth certificate or court document), and serve as the minor’s designated purchaser. The guardian is responsible for regulating the acquisition, dosage, and frequency of use, and for ensuring the minor uses non-smoking methods.

Can I use my Montana medical cannabis card in other states?

Within Montana, present your registry identification card at any licensed dispensary. Because adult-use cannabis is legal for those 21 and older, visitors and residents 21+ can also purchase adult-use products with a valid ID — though without the medical program’s lower tax rate and other benefits.

Montana does not recognize out-of-state medical cards — there is no reciprocity, and patients from other states are not protected under Montana’s medical marijuana laws. If you’re a Montana cardholder traveling elsewhere, some states with reciprocity may recognize a valid out-of-state card, but rules vary widely by state and dispensary, and many require a separate visiting-patient application. States commonly cited as honoring out-of-state cards include Arizona, Hawaii, Maine, Nevada, New Hampshire, New Mexico, Oklahoma, Rhode Island, Utah, and Washington, D.C.

Reciprocity policies change frequently, so always confirm a state’s current rules before you travel — and never transport cannabis across state lines, as that remains illegal under federal law.
