Oklahoma brought in $40.2 million in taxes from over $575 million in medical marijuana sales between July 1, 2024, and April 30, 2025, according to new data released by the state’s Medical Marijuana Authority.
With the tax rate set at 7%, the $40,269,697 in revenue corresponds to $575,281,386 in total sales over the 10-month period. The figure highlights the ongoing strength of Oklahoma’s medical marijuana market, which remains one of the nation’s most active in the nation despite seeing patient numbers decline for several straight months.
In April alone, medical marijuana sales reached $55,895,029, generating $3,912,652 in tax revenue. That marks one of the strongest months of the fiscal year so far.
Medical marijuana tax revenue is deposited into the state’s General Revenue Fund, where it helps fund core services.
Oklahoma voters legalized marijuana in 2018 through the passage of State Question 788. The Oklahoma Medical Marijuana Authority was established to oversee the program, and by August 2018, the state began issuing licenses to patients and businesses. The first legal medical marijuana dispensaries opened their doors on October 26, 2018.
