How to get a medical card in Missouri
Two steps, and the whole thing can be done online:
- Get certified. A Missouri-licensed physician (MD or DO) or nurse practitioner evaluates you and, if appropriate, completes an electronic physician certification. This can be done by telehealth — Missouri has allowed it since 2020.
- Apply with DHSS. Within 30 days of the certification, create an account on the state's registry portal, complete the patient application, upload a Missouri ID or proof of identity and a photo, and pay the fee (about $25).
- Get your digital card. DHSS reviews applications within 30 days — most within 1–2 weeks — and issues a digital PDF card you download and use at any licensed dispensary. Missouri doesn't mail physical cards.
Adults 18+ apply directly; minors register through a parent or guardian caregiver. Since adult use is legal at 21+, see medical vs. recreational to weigh the benefits.
Qualifying conditions in Missouri
Missouri pairs a named list with a strong physician-discretion clause, which makes it one of the more accessible programs. Qualifying conditions include:
- Cancer
- Epilepsy
- Glaucoma
- Intractable migraines
- Chronic conditions causing severe, persistent pain or muscle spasms (including multiple sclerosis)
- Debilitating psychiatric disorders, including PTSD
- HIV/AIDS, Crohn's disease, ALS, and Alzheimer's disease
- Any condition for which a physician could otherwise prescribe an opioid
Critically, Missouri also covers any other chronic or debilitating condition in the physician's professional judgment. That discretion is how conditions like anxiety routinely qualify. See our qualifying conditions overview for how this open standard compares.
Cost breakdown
This is where Missouri shines — it's one of the cheapest programs anywhere:
- State fee — about $25 for three years. The exact amount is adjusted annually for inflation (it's $28.14 in fiscal year 2026). That's well under $10 a year — among the best values in the country.
- Physician evaluation — typically $100–$150. Set by the provider, not the state; telehealth services are often at the lower end. Insurance doesn't cover it.
- Tax savings. Medical patients pay a 4% cannabis tax, while adult-use buyers pay a 6% state excise plus state and local sales taxes — often 10% or more combined. See our cost of an MMJ card guide.
Possession & purchase limits
Medical patients get more than adult-use buyers:
- Up to 6 ounces of dried flower per 30-day period (or equivalent), versus a 3-ounce cap for adult-use. Patients who need more can request a higher limit with two physician certifications.
- Home cultivation is allowed with an authorization. For an extra fee (about $56 for three years), a patient can grow up to 6 flowering plants, plus immature plants, in an enclosed, locked space not visible to the public. Growing without that authorization is illegal even with a card.
See possession limits by state for the full comparison.
Renewal rules
Missouri's three-year card means renewals are infrequent:
- Cards are valid for three years — among the longest in the country.
- Renewing requires a fresh physician certification plus the state fee, submitted through the registry portal (telehealth is fine). Start 30–60 days before expiration: there's no grace period, so if your card lapses you immediately revert to the adult-use tax rate and the 3-ounce limit. The renewal process mirrors the original application.

Frequently asked questions
Do I need a medical card if recreational is legal in Missouri? +
Not to buy, if you're 21 or older. But medical patients pay a 4% tax instead of the higher combined adult-use rate, can possess up to 6 ounces per month instead of 3, can grow more plants at home, and qualify at 18. Because the card is about $25 for three years, the savings add up fast for regular buyers.
Can I get a Missouri medical card by telehealth? +
Yes. Missouri has allowed telemedicine certifications since 2020. A Missouri-licensed physician or nurse practitioner can evaluate you by video, file the certification electronically, and then you complete your application on the state portal within 30 days.
How much does a Missouri medical card cost? +
The state fee is about $25 ($28.14 in fiscal year 2026) and covers a full three-year card — one of the best values anywhere. The physician evaluation is separate, usually $100–$150. A home-cultivation authorization, if you want one, is roughly $56 for three years.
What conditions qualify in Missouri? +
Named conditions include cancer, epilepsy, glaucoma, intractable migraines, severe chronic pain, multiple sclerosis, PTSD and other psychiatric disorders, HIV/AIDS, Crohn's, ALS, and Alzheimer's. Missouri also covers any other chronic or debilitating condition in the physician's professional judgment, so conditions like anxiety routinely qualify.
How long is a Missouri medical card valid? +
Three years — among the longest in the country. Renewing requires a fresh physician certification and the state fee through the registry portal. There's no grace period, so renew 30–60 days early; if the card lapses you revert to adult-use tax rates and possession limits until it's renewed.
Can I grow my own, or use an out-of-state card in Missouri? +
Yes to growing — with a cultivation authorization (about $56 for three years) you may grow up to 6 flowering plants, plus immature plants, in a secure private space. Missouri's program is intended for residents and generally doesn't honor out-of-state cards for dispensary purchases, though visitors 21+ can buy recreationally.
