Oklahoma Medical Marijuana Program Reports 319,965 Active Patients and 4,500 Licensed Businesses

According to a new report released by the Oklahoma Medical Marijuana Authority, the state now has 319,965 active medical cannabis patients and over 4,500 active cannabis business licenses (including over 1,450 dispensaries). The number of active marijuana patients declined slightly to start the new year, down from around 324,000 in September. The current total is also down sharply from January 2025, when patient registrations were reported at 340,258. Experts say the decline is due in part to stricter oversight of the state’s medical cannabis program including increased denials, as well as an increase in popularity of hemp-derived THC, which can be easily purchased online without being a registered medical cannabis patient.

Caregiver participation followed a similar pattern. The state now lists 1,078 active caregivers, down from 1,222 at the same point last year.

On the business side, regulators report a total of 4,512 active marijuana licenses, compared to 5,783 in January 2025. Growers continue to make up the largest share of licensed operators, with 2,261 active cultivation licenses. Dispensaries remain the second-largest category, totaling 1,453 active licenses statewide.

Processors account for another 710 licenses, while transportation businesses total 60. The report also lists 19 licensed laboratories and eight waste disposal licensees. One education license remains active, while no research licenses are currently listed.

When patient, caregiver, and business licenses are combined, the state reports 325,555 total active marijuana-related licenses. That figure is down from 347,263 one year ago, underscoring the broader contraction seen across the program since early 2025.

Despite Oklahoma’s medical cannabis program shrinking in recent months, it remains one of the largest in the nation.
