Oklahoma proposes strict cap on cannabis cultivation, limits THC

With the medical marijuana boom in Oklahoma now over, lawmakers are considering permanently limiting commercial marijuana cultivation permits in the once storied state.

A bill recently introduced in the state legislature would increase the number of cultivation licenses the Oklahoma Medical Marijuana Authority can issue to 2,550, according to NPR affiliate KOSU.

House Bill 3144, sponsored by Rep. State Republican Rusty Cornwell, the sponsor of the previous moratorium, is one of several marijuana-related measures to be considered in 2026.

Oklahoma could close restrictions on the cultivation of medical cannabis after the suspension

Once seen as one of the hottest markets in the country due to its low entry threshold and number of license caps, Oklahoma has seen its cannabis market shrink significantly in the past few years.

In 2023, when there are 6,675 registered farmers in the state, Gov. Kevin Stitt extended the moratorium on new permits until August of this year.

Since then, the number of farmers decreased by almost two-thirds. There are currently 2,454 licensed cannabis growers in Oklahoma, according to state data.

State law enforcement and election officials also say the Oklahoma MMJ is overrun by criminal organizations, including foreign corporations.

Oklahoma medical cannabis edibles THC limits

Edibles manufacturers face new potential restrictions. Senate Bill 1591, introduced by Republican state Sen. Paul Rosino, would cap the THC allowed in edible marijuana at 10 milligrams per serving and 100 milligrams per packet.

That would put Oklahoma in line with other states, but it could be a game-changer for Oklahoma’s medical market, which has allowed for high-potency products.

House Bill 3013, authored by Rep. Jacob Rosecrants, a Democratic state representative, will approve stricter pesticide testing. The bill requires final harvest and production batch samples to be tested for 72 specific pesticides, with strict limits set.

Financial transparency and local cannabis taxes

Senate Bill 1364, sponsored by Democratic state Sen. Mark Mann, would empower OMMA to require marijuana businesses to disclose any outstanding federal fees, fines, taxes or other liabilities before sales are terminated.

Finally, Senate Bill 1846 gives local governments the authority to levy their own excise taxes, which would create a cumulative tax rate across the state.

Currently, local governments can levy a local sales tax in addition to the 7% state cannabis excise tax collected at the point of sale, as well as the state sales tax.

Oklahoma MMJ dispensaries reported sales of $55 million in December 2025, the latest monthly data available.
