Cannabis Compliance in Oklahoma: What Every Operator Should Know

Oklahoma’s medical cannabis market has had one of the fastest growth stories in the country since legalization in 2018, becoming one of the most active (and most closely regulated) industries in the U.S.

Whether you’re running a grow, a processing facility, or a dispensary, staying compliant in Oklahoma means juggling rules from OMMA, OBNDD, and METRC - often all at once. It can feel like a lot, but once you understand how these systems work together, it gets a whole lot easier to stay ahead.

OMMA Compliance Requirements for Cannabis Businesses

The Oklahoma Medical Marijuana Authority (OMMA) oversees all commercial cannabis operations in the state, from licensing to product safety. Its mission is to ensure transparency and protect patients through proper tracking, testing, and enforcement.

Through the OMMA website, businesses can find the most current licensing and compliance information. Regularly reviewing updates and FAQs is essential, as Oklahoma’s regulations evolve frequently.

Understanding the Role of OBNDD in Cannabis Regulation

While OMMA governs licensing and reporting, the Oklahoma Bureau of Narcotics and Dangerous Drugs Control (OBNDD) oversees all controlled substances, including cannabis.

After receiving an OMMA license, operators must register with OBNDD before cultivating, processing, or selling any cannabis products. This registration must be renewed annually, and maintaining it is mandatory for legal operation. Overlooking this step is one of the most common compliance errors among new licensees and can result in fines or suspension.

Staying Compliant with Oklahoma’s METRC Seed-to-Sale System

Since 2022, METRC has been the state’s official seed-to-sale tracking system, giving regulators and operators complete visibility into the cannabis supply chain. All plants and products must be tracked accurately to prevent diversion and ensure consumer safety.

Operators are responsible for:

• Tagging every plant and product with RFID identifiers
• Recording harvests, transfers, and destructions in real time

Errors or omissions in METRC reporting can lead to serious compliance issues. Many Oklahoma operators rely on GrowFlow’s integrated platform to automate data syncing, eliminate manual mistakes, and maintain full regulatory alignment.

Testing, Packaging, and Labeling Regulations

All medical cannabis in Oklahoma must be tested by a licensed laboratory for potency, pesticides, heavy metals, and microbial contaminants. Products must be sold in child-resistant, tamper-evident packaging and display clear, accurate potency and batch information.

Testing and labeling requirements are updated periodically, so operators should verify compliance before each batch release to avoid enforcement actions or product recalls.

Preparing for OMMA and OBNDD Inspections

Compliance extends beyond documentation. Both OMMA and OBNDD conduct routine and unannounced inspections. Operators must keep accurate records of testing results, inventory adjustments, waste management, and employee logs.

Oklahoma law also requires businesses to retain records for at least three years, even after closure or relocation. Being organized and transparent helps ensure that inspections are efficient and uneventful.
