An OMMA-registered physician can recommend medical marijuana for an Oklahoma patient license — and many Duncan patients qualify for the reduced state fee without knowing it.
Oklahoma's program is run by the Oklahoma Medical Marijuana Authority (OMMA). There's no list of qualifying conditions; your physician decides.
Recommending physicians must be registered with OMMA, as of Jan. 1, 2026.
Apply within 30 days of the recommendation date.
Upload ID, Oklahoma residency, a photo, and proof of reduced-fee status if you have it.
OMMA typically reviews applications in about two weeks. Licenses last two years.
OMMA charges a reduced fee to three groups of patients. It's the same two-year license — you just need to show proof when you apply.
Oklahoma Medicaid members qualify with proof of current enrollment.
Medicare beneficiaries qualify with proof of coverage.
Veterans with a 100% disability rating qualify with proof of their rating.
Worth knowing: the reduction applies to OMMA's state fee only. Medicare and Medicaid don't pay for medical marijuana, and the physician's visit fee is separate. Upload your proof with your application — see OMMA's Patient Licenses page for accepted documents.

In April 2026, state-licensed medical marijuana moved from Schedule I to Schedule III. It's still a federally controlled substance, which is one reason federal insurance programs don't cover it.
Most of Duncan's licensed medical dispensaries sit along U.S. 81, the city's main north-south route. Dispensaries open and close often in Oklahoma, so confirm a store's license is active before you go.

Duncan, the seat of Stephens County, sits along the historic Chisholm Trail and is home to the Chisholm Trail Heritage Center. It's also where Erle P. Halliburton founded his oilfield services company. Duncan residents follow the same statewide rules as every patient in Oklahoma's medical marijuana program.
Oklahoma voters approved medical marijuana through State Question 788 in 2018. The Oklahoma Medical Marijuana Authority licenses patients, caregivers, and businesses, and registers recommending physicians.
Driving impaired is illegal, marijuana remains a federally controlled substance, and federal and tribal rules still apply on federal land and tribal trust land. See OMMA for current rules.
