Oklahoma proposes hard cap on cannabis cultivation, THC limits

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

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

House Bill 3144, authored by Republican state Rep. Rusty Cornwell, sponsor of a previous permit moratorium, is one of several cannabis-related measures lawmakers will consider in 2026.

Oklahoma could cap medical cannabis cultivation limits after moratorium

Once seen as one of the hottest cannabis markets in the country thanks to its low barrier for entry and lac of license caps, Oklahoma has seen its state cannabis market shrink dramatically over the past few years.

In 2023, when there were 6,675 registered growers in the state, Gov. Kevin Stitt extended a pause on new permits until August of this year.

Since then, the number of cultivators declined by nearly two-thirds. There are currently 2,454 licensed cannabis cultivators in Oklahoma, according to state data.

State law enforcement and election officials have repeatedly claimed that Oklahoma MMJ is overrun with criminal organizations, including foreign cartels.

Oklahoma medical cannabis edibles THC limits

Edibles makers face potential new restrictions. Senate Bill 1591, introduced by Republican state Sen. Paul Rosino, would cap the THC allowed in cannabis edibles at 10 milligrams per serving and 100 milligrams per package.

That would put Oklahoma in line with other states, but would be a shift for Oklahoma’s medical market, which has allowed higher-potency products.

House Bill 3013, written by Democratic state Rep. Jacob Rosecrants, would mandate rigorous pesticide testing. The bill requires final harvest and production batch samples to be tested for 72 specific pesticides, establishing strict limits.

Financial transparency and local cannabis taxes

Senate Bill 1364, sponsored by Democratic state Sen. Mark Mann would empower OMMA to require cannabis businesses to disclose any outstanding state fees, fines, taxes or other debts before a sale can be completed.

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

Currently, local governments can impose local sales taxes in addition to a 7% state cannabis excise tax collected at the point of sale, plus the state sales tax.

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