It’s been 18 months since Oklahoma launched its legal medical cannabis program, and licensing and revenue have both exceeded initial expectations, according to a Cherokee Phoenix report.

Roughly 8% of adults have a medical cannabis card, the news outlet reported, and the state has licensed more than 2,200 dispensaries, which means there is one for every 1,786 residents, or one for every 100 card holders.

The state has issued 4,757 total cultivation, processing and dispensary licenses to date, Cherokee Phoenix reported, and only 770 have not been renewed.

The Oklahoma Tax Commission has reported that medical cannabis sales reached $345 million in 2019, according to the news outlet, and the state collected $55 million in total tax revenue.

New Frontier Data has rated Oklahoma as the second-most saturated market behind New Mexico, Cherokee Phoenix reported, due to minimal financial obstacles and a lack of qualifying conditions—doctors can ultimately decide whether to prescribe cannabis on a case-by-case basis.
