How to check an Oklahoma medical marijuana dispensary

1. Make sure your license is active

You must show your patient license every time you buy at a dispensary, and the dispensary must check it each time.¹ If OMMA has just said yes to your application, you can show the OMMA email or your status in the OMMA MedPortal until your card arrives.¹

To check your own license, open the Patient/Caregiver tab in OMMA Verify and enter your license number. It shows the expiration date, the county and whether the license is active.²

• Adult license: Oklahoma residents 18 and older. It lasts up to two years.¹
• Short-term license: Oklahoma residents whose physician recommends medical marijuana for a shorter time. It lasts up to 60 days.¹
• Out-of-state (temporary) license: for people with a medical card issued by their own state’s government. It lasts 30 days. A recommendation from an out-of-state doctor does not count.¹
• Minors: need two physicians and a parent or guardian. The parent or guardian named on the license buys for the minor, and a minor may enter a dispensary only with them.¹

The application fee is $100, or $20 with proof of Medicaid (SoonerSelect), Medicare or 100% disabled veteran status, plus a card processing fee. OMMA says it processes patient applications within 14 business days.¹

2. Look up the dispensary in OMMA Verify

OMMA Verify lists each business license with its license number, business name, license type, status and expiration date. The details view also shows the store name (“DBA”) and physical address.⁴

1. Go to OMMA Verify and choose the Business tab.
2. Type the business name or license number and select Search.
3. Check that the license type says Dispensary and the status says Active. Results can also show statuses like Expired, Cancelled or Suspended.⁴ If you see one of those, don’t buy there.
4. Select View and check that the store name and physical address match the store you are in.⁴

No delivery: OMMA’s rules do not let licensed businesses deliver medical marijuana to patients or caregivers. Buy in person at the store.⁵

3. Check the package and label

Labels must show the name and license number of the business that sold the product to the dispensary, the product name, the batch number, the net weight, ingredients, the Oklahoma Uniform Symbol, THC potency from the lab report, total terpenes and the date it was packaged.⁵ The THC on the label must be within 15% of the lab result.⁵

Packages must be child-resistant and must carry warnings, including “Keep out of reach of children” and a warning about use during pregnancy.⁵ Since June 1, 2025, flower must come pre-packaged, in sizes from 0.5 gram to 3 ounces.⁶

The label must also say the product was tested for contaminants.⁵ That is a required statement, not a promise. OMMA runs its own lab and uses secret shoppers to check labels and testing.¹⁰

4. Check for recalls

OMMA posts embargoes and recalls on its recall list , each with a product list.⁷ Find the batch number on your label and compare it to the list. If it matches, throw the product away or contact the dispensary where you bought it.⁷

Dispensaries must tell patients who bought a recalled product.⁷ Recalls can be large. In March 2026, OMMA ordered a recall of products tested by one lab between April 2023 and July 2025.⁷

If a product made you sick, call your doctor and fill out OMMA’s Health Impact Form .⁷⁸

Warning signs

• Anyone offering to deliver. Licensed businesses may not deliver to patients.⁵
• A seller who doesn’t check your license. Dispensaries must check it every time you buy.¹
• Loose flower weighed out at the counter. Flower must be sold pre-packaged. Dispensaries may open packages only to make display samples or pre-rolls.⁶
• A license number on the label you can’t find. In January 2026, OMMA embargoed products found at a dispensary that carried license numbers OMMA never issued.⁷ You can look up the license number on the label in OMMA Verify .
• Packaging that appeals to kids, such as cartoons or toys, or labels that claim health benefits. OMMA’s rules ban both.⁵

If something doesn’t look right

You can file a complaint about a licensed business with OMMA. Its Office of Investigation and Enforcement reviews complaints. You may stay anonymous, and threats to public health come first.⁹ If you had a bad reaction to a product, use the Health Impact Form instead.⁹

You can also call OMMA at 405-522-6662 , 8:30 a.m. to 4:30 p.m. on weekdays.¹¹
