Oklahoma 2026 Medical Marijuana Legislation Update

Oklahoma’s 2026 legislative session is shaping up to be consequential for the state’s medical marijuana industry. Lawmakers are advancing multiple bills that would affect taxation, product formulation, licensing, ownership transfers, and patient access within health care facilities. Below is an overview of the most significant proposals and their current status.

HB 3314 – County Public Service Impact Tax on Retail Marijuana

HB 3314 would authorize counties to impose a public service impact tax of up to 15% on the retail sale of marijuana within county limits. The tax could only be implemented upon approval by a majority of county voters at a special election.

The measure expressly exempts marijuana grown by individuals on privately owned property that is not sold. If approved, tax revenues would be deposited into the county general fund and designated for specified purposes, including support for county sheriffs, local police departments, fire departments, and remediation of dilapidated properties.

HB 3314 is currently filed as introduced and, if enacted, would take effect November 1, 2026. For operators, this bill introduces the potential for significant local tax variability across counties.

HB 3525 – Oklahoma Medical Marijuana Act of 2026

HB 3525 creates the “Oklahoma Medical Marijuana Act of 2026.” As introduced, the bill primarily establishes a short title and effective date rather than implementing substantive regulatory changes.

At this stage, the measure appears structural rather than operational. HB 3525 is currently in introduced form and would take effect November 1, 2026.

SB 1591 – THC Limits and Packaging Requirements (Emergency Clause)

SB 1591 would impose statutory THC caps on edible medical marijuana products:

• No more than 10 milligrams of THC per individual edible

• No more than 100 milligrams of THC per package

In addition to THC limits, the bill strengthens packaging and labeling requirements. Provisions include child-resistant packaging, restrictions on marketing that could appeal to minors (such as cartoon imagery), mandatory warning statements, and prohibitions on misleading health claims.

Importantly, SB 1591 contains an emergency clause, meaning it would take effect immediately upon passage and approval. The bill has advanced in Senate Floor Version and received a “Do Pass” recommendation from committee.

For processors and dispensaries, this measure would require immediate compliance adjustments if enacted.

HB 3143 – Moratorium Extension and Ownership Transfer Restrictions

HB 3143 would extend the current moratorium on new dispensary, processor, and commercial grower licenses through August 1, 2028, unless lifted earlier by OMMA.

The bill also significantly tightens ownership transfer rules. It prohibits license transfers while a licensee is subject to administrative action that could result in revocation, suspension, or nonrenewal. Any pending administrative action or appeal must be fully resolved before a transfer application may be submitted. Additionally, if a license is revoked, annulled, or suspended, the licensee would be barred from applying for a transfer for at least six months following completion of the sanction.

HB 3143 has advanced from committee with a “Do Pass” recommendation and would become effective August 1, 2026.

This measure materially affects transactional planning and due diligence for buyers and sellers in the market.

SB 1508 – Compassionate Access to Medical Marijuana Act

SB 1508 would require licensed health care facilities to permit medical marijuana use by terminally ill patients (defined as individuals with a prognosis of one year or less), subject to specific safeguards.

Facilities would be required to prohibit smoking and vaping, document medical marijuana use in patient records, require proof of a valid OMMA license, and implement reasonable storage and safety protocols. The bill does not apply to emergency departments during the provision of emergency services.

SB 1508 is currently introduced and would take effect November 1, 2026.

Final Takeaways

Taken together, these bills reflect continued legislative attention to product safety, local control, regulatory enforcement, and patient access. Operators should pay particular attention to:

• Potential local tax exposure (HB 3314)

• Immediate compliance obligations tied to THC limits (SB 1591)

• Extended license moratorium and transfer restrictions (HB 3143)

We will continue monitoring these measures as they move through the legislative process and will provide updates as significant developments occur.
