Cannabis in Oklahoma

Oklahoma is a medical-only state with one of the largest medical markets in the country. Voters approved State Question 788 in June 2018, and the Oklahoma Medical Marijuana Authority (OMMA) licenses patients, growers, processors, dispensaries, labs and transporters. OMMA's January 14, 2026 report counted 4,512 licensed businesses, including 1,453 dispensaries and 2,261 growers, and 319,965 active patients, down from 340,258 in January 2025. OMMA and the Marijuana Herald link the decline partly to stricter oversight, more denials and the popularity of hemp-derived THC.

A patient needs a physician recommendation and an OMMA license. The fee is $100 plus a $4.30 card-processing charge, or $22.50 at the reduced rate for Medicaid (SoonerSelect), Medicare and 100% disabled veterans, and OMMA says it processes applications within 14 business days. Adult licenses last up to two years; an out-of-state license lasts up to 30 days at the same $104.30. Since January 1, 2026 the recommending physician must be registered with OMMA and have completed cannabis education under SB 1066, and a physician cannot work at the same location as a dispensary. Patients may carry 3 ounces, keep 8 at home, hold 1 ounce of concentrate and 72 ounces of edibles, and grow six mature plants and six seedlings, according to state rules as summarized by third parties.

Without a license, possession of up to 1.5 ounces by someone who can state a medical condition is a misdemeanor with a fine of up to $400, according to an Oklahoma Bar Journal analysis; other unlicensed possession is charged as a broader misdemeanor. A moratorium on new grower, processor and dispensary licenses has been in effect since August 26, 2022, and OMMA now lists it as running through August 1, 2028.

Politics has turned against the program. Governor Kevin Stitt asked lawmakers in February 2026 to send the marijuana issue back to voters and "shut it down", but Senate leaders declined, and no state question is on a 2026 ballot. A 2026 adult-use initiative, State Question 837, did not qualify. Read this page as general information, not legal advice.
