Missouri facts
On June 28, 2019, the Missouri Department of Health and Senior Services began taking applications from qualifying patients and caregivers for medical marijuana ID cards. Patients and caregivers must be state residents to apply. The patient/caregiver registration website is available on medicalmarijuana.mo.gov. The state health department only accepts applications submitted through the online registry.
After uploading an application, patients will receive an electronic notification about the status of their application, frequently within 48 hours. The health department does not provide physical cards to patients. Instead, patients should log into their Missouri Medical Marijuana Program Registry account to download a copy of their card, then print it out.
Missouri legalized medical marijuana with the passage of Amendment 2 in Nov. 2018. That measure set out these qualifying conditions:
- Cancer
- Epilepsy
- Glaucoma
- Intractable migraines unresponsive to other treatment
- Conditions that cause persistent pain or muscle spasms, including multiple sclerosis, Parkinson’s disease, and Tourette’s syndrome.
- Debilitating psychiatric disorders including but not limited to, post-traumatic stress disorder, if diagnosed by a state licensed psychiatrist
- HIV/AIDS
- A chronic medical condition normally treated with prescription medication that can lead to dependence, when a physician determines that medical marijuana could be an effective and safer treatment. (This is most commonly used with regard to prescription opioids.)
- Any terminal illness
- Any other chronic or debilitating medical condition that, in the professional judgment of a physician, might be helped by the use of medical cannabis, including, but not limited to:
- Hepatitis C
- Amyotrophic lateral sclerosis/Lou Gehrig’s Disease
- Inflammatory bowel disease
- Crohn’s disease
- Huntington’s disease
- Autism
- Neuropathies
- Sickle cell anemia
- Agitation of Alzheimer’s disease
- Cachexia (wasting syndrome)

No. There is no reciprocity between Missouri’s Medical Marijuana Program and other state medical marijuana programs. Just because you are licensed in another state doesn’t automatically qualify you for a license in Missouri. Patients may purchase medical marijuana in Missouri only upon presentation of a Department-issued patient identification card.
Per 19 CSR 30-95.030, no qualifying patient shall consume marijuana for medical use in a public place, unless provided by law. 19 CSR 30-95.010 defines a public place as any public or private property, or portion of public or private property, that is open to the general public, including but not limited to, sidewalks, streets, bridges, parks, schools and businesses. See 19 CSR 30-95.010(33) for more information.
Patients and caregivers with a valid department-issued identification card may legally possess medical marijuana now subject to the requirements and limitations in 19 CSR 30-95.030 and Article XIV of the Missouri Constitution.
The qualifying patient’s physician may certify up to four ounces of dried, unprocessed marijuana, or its equivalent, in a 30-day period. If there is a compelling reason why the qualifying patient needs a greater amount, then the Department requires two independent physician certifications specifying what other amount the qualifying patient needs. See 19 CSR 30-95.030(5)(E) for more information.
The patient identification card does not offer individuals protections from violating laws pertaining to operating a motorized vehicle while under the influence. Nothing in Article XIV permits a person to operate, navigate, or be in actual physical control of any dangerous device or motor vehicle, aircraft or motorboat while under the influence of marijuana.
