Oklahoma runs one of the most accessible medical cannabis programs in the United States, established by State Question 788 in 2018 and regulated by the Oklahoma Medical Marijuana Authority (OMMA).
There is no fixed list of qualifying conditions — licensed physicians may recommend a medical card at their discretion, which has produced an unusually high number of patients and dispensaries per capita. Adult-use sales are not legal; a 2023 recreational ballot measure was rejected.
Patients must hold a valid OMMA card to purchase. Oklahoma City anchors the market.
