Oklahoma medical marijuana rules: what to know and how to check
Oklahoma allows medical marijuana only. To buy it, you need a patient or caregiver license from the Oklahoma Medical Marijuana Authority (OMMA). There is no list of qualifying conditions: an Oklahoma physician decides whether to recommend it. Buy only in person from an OMMA-licensed dispensary, and look the dispensary up in OMMA Verify before you buy.

What’s different in Oklahoma
Oklahoma allows medical marijuana only. Voters created the program with State Question 788 in 2018. In March 2023, voters turned down State Question 820, which would have allowed adult use: 217,078 voted yes and 349,284 voted no.
Oklahoma law has no list of qualifying conditions. An Oklahoma physician signs a recommendation using the same standards they would use for any medicine. Oklahoma residents 18 and older can get an adult patient license that lasts up to two years. Patients under 18 need two physicians and a parent or guardian. People from other states who hold a medical card issued by their state government can get a 30-day temporary license.
Only dispensaries licensed by the Oklahoma Medical Marijuana Authority (OMMA) may sell medical marijuana to patients and caregivers. You must show your license every time you buy. Licensed businesses may not deliver to patients, so you buy in person.
Patients may grow their own plants at home, within limits. You may not sell or share your medical marijuana, and you may not take it across state lines. OMMA's rules say a state medical marijuana license is not valid on tribal trust or restricted land or on federal land in Oklahoma.
Hemp products are different. OMMA's rules say products with delta-8 or delta-10 THC grown, made or sold under the Oklahoma Industrial Hemp Program are not "marijuana" under those rules.
