About

The Oklahoma Medical Marijuana Authority (OMMA) has issued a mandatory recall for medical marijuana products tested by Greenleaf Labs LLC (LAAA-MP4O-T1EE) between April 2023 and July 2025. This action follows a previous emergency order establishing product safety concerns that remain unresolved by the licensee.

Information for Patients

Improperly tested medical marijuana can pose immediate health risks. Mold and yeast levels exceeding compliance thresholds may lead to adverse reactions.

Patients who believe they purchased impacted products should:

  1. Check products: Check the production or Certificate of Analysis (COA) batch number on the product and compare it to the table included below.
  2. Contact the dispensary: Patients should dispose of recalled products or contact the dispensary where the item was purchased.
  3. Monitor health: If patients experience an adverse reaction after consuming an impacted product, contact your physician immediately and complete OMMA's Health Impact Form.
  4. Report violations: Patients who see recalled products on shelves are encouraged to submit a tip via OMMA's Business Complaint Form.

Required Actions for Commercial Licensees

Dispensaries should immediately audit Metrc inventories to ensure no ‘test failed’ products remain on shelves. These products cannot legally be sold to patients.

Commercial licensees are responsible for disposing of recalled products per OMMA rules  and notifying any impacted downstream businesses and patients. Additionally, the licensee whose harvest or production batches are being recalled bears responsibility for disposal costs of all waste.

Pursuant to OAC 442:10-8-1(g)(2)(C)(vi), a licensee’s failure to timely comply with recall provisions may result in revocation, suspension and monetary penalties.

FAQs

An embargo is a hold on specific product(s) that were found to:

  1. exceed the allowable testing thresholds set forth under our rules;
  2. contain analytes that could be poisonous, harmful to health or otherwise unsuitable or unsafe for human consumption;
  3. be in violation of applicable laws, rules or regulations.

Licensed businesses cannot engage in commercial activity (sale, donation, transfer, etc.) with embargoed products without the OMMA's permission. If your business is in possession of an embargoed product, you cannot send it to a waste facility (or other commercial license). You must await further instructions from the OMMA.

A recall takes place when the OMMA has ordered for the disposal of medical marijuana or medical marijuana products that have been sold to patients or caregivers AND meet at least one of the criteria below:

  1. exceed allowable testing thresholds set forth under our rules;
  2. are the subjects of an embargo or a derivative thereof;
  3. fail to meet standards set forth in our rules

The commercial licensee whose harvest or production batch is being recalled shall bear the costs for disposal of all medical marijuana waste.

After issuing the recall, dispensaries that have sold the product and the commercial licensee who grew or produced the product must assist in the recall in any way they can.

If you or your caregiver purchased a product from the above list, do not consume the product. Contact the dispensary for more information.

An embargoed product is in a holding pattern until the courts can determine whether OMMA has the authority to seize and destroy the product in question.

A recall occurs once we have confirmation that a product has been sold to patients and meets one of the below criteria:

1) exceeds allowable testing thresholds set forth under our rules;
2) is the subject of an embargo or a derivative thereof;
3) fails to meet the standards set forth in our rules.

Put another way, if a product has been embargoed, a business (including a dispensary) cannot engage in any commercial activity with that product. They can't sell it, distribute it, transport it, dispose of it, etc. They must also tag the product so it's obvious the product is under an embargo.

If a product has been recalled, the product needs to be destroyed and the businesses who have sold the product (either to patients or other businesses) are responsible for assisting with the recall in any way they can. Patients or caregivers who have purchased a recalled product need to contact the dispensary from which they bought the item to determine how they should move forward in assisting with the recall.

Patients are encouraged not to consume embargoed/recalled products.

Dispose of the product or contact the dispensary you purchased from. If a patient consumes any embargoed or recalled products and experiences an adverse health reaction, they should contact their physician immediately and fill out OMMA’s Health Impact Form.

If a business is selling a product that has been embargoed or recalled, please notify OMMA immediately via our complaint form.
