Oklahoma Cannabis Laws

Find important info here on Oklahoma marijuana dispensary laws and licensing procedures, including how to apply for a license and cannabis compliance.


In June 2018, Oklahoma became the 30th U.S. state to legalize medical marijuana under SQ 788. Residents over 18 with a physician's recommendation can apply for a medical card to buy medical marijuana from licensed dispensaries, with exceptions for non-residents and minors.

The Oklahoma Medical Marijuana Authority (OMMA) oversees licensing, and the market has grown rapidly since August 2018, with over 7,300 business licenses issued, including 1,800+ dispensaries. More than 5% of the state's population are registered medical marijuana patients.

In September 2020, OMMA partnered with Metrc for seed-to-sale tracking, but implementation was delayed. On Feb 25, 2022, an agreement was reached for full compliance by May 26, 2022, to improve cannabis business operations. Metrc's implementation has been crucial in combating illicit marijuana businesses. Dispensaries had urged OMMA to move forward with it for enhanced compliance and safety.

Oklahoma's cannabis landscape has seen significant changes in recent years, making it crucial for both residents and businesses to stay informed and compliant with evolving cannabis regulations. For detailed information and updates on Oklahoma's dispensary laws and licensing process, visit OMMA's website. On this page, you’ll get an overview of the state's medical marijuana laws, including regular updates and essential information you need to know.

Latest Updates

In the ever-evolving world of cannabis legislation, staying informed is paramount. Here are some time-sensitive updates you need to be aware of in Oklahoma:

  • Pressure is growing in the Oklahoma Legislature to reconsider the contract for the state's marijuana tracking system due to complaints from lawmakers and cannabis businesses about the current system implemented by Metrc on behalf of OMMA. Approximately one out of every five businesses regulated by OMMA was issued $500 fines last year because they had not set up the proper account with Metrc.

  • In March 2023, Oklahoma residents voted against a state-wide referendum to legalize recreational cannabis use. Despite the state's thriving medical marijuana industry, the ballot question proposing recreational cannabis sales to adults over 21 was met with widespread opposition from law enforcement, educators, and religious and political leaders. Supporters argue that cannabis legalization in Oklahoma is inevitable due to widespread usage, but opponents emphasize law and order in the state.

  • Oklahoma lawmakers have proposed numerous bills related to the cannabis industry in 2023. These bills address various aspects, including potency limits on THC, location restrictions for dispensaries, taxation of cannabis farms, temporary business licenses, conflicts of interest disclosure, product testing procedures, and regulations for medical marijuana doctors. These legislative efforts reflect the continued growth of the cannabis industry in Oklahoma and further expansion is anticipated if a statewide referendum on recreational marijuana is approved by next year.

OMMA has partnered with Metrc for inventory tracking and reporting services to cannabis businesses, and Metrc system is gradually being integrated with OMMA reporting requirements.

Metrc is a fully integrated compliance system that allows real-time tracking and tracing of marijuana products. Licensees will have to attach unique, serialized tags to every product, which will have readable text, barcodes, and RFID chips to uniquely identify every plant or flower, both physically and digitally in the cloud software. Retailers will then enter information such as weight, transfer of custody, and test results into the online software platform, which will be then available to the business owners and the OMMA. To familiarize yourself with how Metrc works, you may check out videos on its YouTube channel and complete metrc training with your specific Metrc account number.

  • Licensed medical marijuana businesses have until May 26, 2022, to comply with the Metrc seed-to-sale tracking system
  • Dispensaries have until Aug 24, 2022, to sell or legally dispose of untagged medical marijuana products in their inventory.
  • OMMA will conduct at least five online seminars by May 26 to educate licensees on the new seed-to-sale system
  • OMMA will ensure adequate Call Center staff is on hand to respond to questions about METRC implementation.

Until then, dispensaries can keep following the previous reporting method as outlined below:

The OMMA developed a monthly reporting template that must be submitted on the 15th day of every month. The monthly reporting template includes:

  • Weight of cannabis purchased at wholesale, tracked by batch numbers
  • Weight of cannabis sold to patients, tracked by batch numbers
  • Accounting for any waste or destroyed products
  • Total sales in dollars
  • Tax collected in dollars
  • Tax due in dollars

What are the laws on record keeping?

All records must be maintained for at least seven years after the date of recording. These records must be accessible to auditors within 15 days of being requested.

Who has oversight and auditing responsibilities?

The Oklahoma Department of Health will have oversight and auditing powers over all of Oklahoma’s commercial medical marijuana operations.

What are the penalties for breaking compliance laws?

A dispensary will be subjected to penalties for non-patient sales and/or gross discrepancies in inventory tracking that cannot be explained. The first offense will come with a fee of $5,000 and a second offense (in a two-year period) will result in a revocation of license. Learn more about how to run a compliant dispensary in Oklahoma.
