Section 442:10-8-1 - [Effective until 9/14/2025] Testing standards and thresholds

(a)Purpose. To ensure the suitability and safety for human consumption of medical marijuana and medical marijuana products, growers and processors are required to test medical marijuana and medical marijuana products for microbials, mycotoxins, residual solvents, pesticides, THC and cannabinoid concentration, terpenoid type and concentration, heavy metals, foreign materials and filth, and water activity and moisture content in accordance with the following standards and thresholds. No laboratory may test medical marijuana without a valid, unexpired testing laboratory license issued by the Authority. A licensed laboratory shall only send samples for testing to another Oklahoma licensed laboratory.

(b)Batches.

(1)Batch size. Growers shall separate all harvested medical marijuana into harvest batches that weigh less than or equal to fifteen ([LESS THAN OR EQUAL TO] 15) pounds with the exception of any plant material to be sold to a licensed processor for the purposes of turning the plant material into concentrate which may be separated into harvest batches that weigh less than or equal to fifty ([LESS THAN OR EQUAL TO] 50) pounds. Processors shall separate all medical marijuana product into production batches that contain a volume that is less than or equal to four ([LESS THAN OR EQUAL TO] 4) liters of liquid medical marijuana concentrate or that weigh less than or equal to nine ([LESS THAN OR EQUAL TO] 9) pounds for nonliquid medical marijuana products, and medical marijuana infused final products shall contain less than or equal to one-thousand ([LESS THAN OR EQUAL TO] 1,000) grams of total delta-9-tetrahydrocannabinol ([DELTA]-9-THC).

(2)Research and Development ("R&D") testing. Growers and processors may submit samples for research and development testing. R&D testing may be performed by a licensed laboratory in accordance with these Rules:

(A) Passing R&D test results. If a sample submitted to a laboratory passes a R&D test, it shall not constitute a pass for the purposes of compliance with required testing under this Subchapter;

(B) Failing R&D test results. If a sample submitted to a laboratory fails a R&D test, laboratories shall clearly note in the State's inventory tracking system and on any COA created for an R&D sample that the test results are for R&D purposes only; and

(C) Growers and processors shall ensure that any R&D testing done under this subsection is appropriately documented and identified in the State's inventory tracking system.

(c)Frequency. Growers and processors shall ensure samples from each final harvest batch and final production batch are collected, labeled, and tested in accordance with the Oklahoma Medical Marijuana and Patient Protection Act, 63 O.S. § 427.1 et seq., and these Rules.

(d)Prohibitions. Growers, processors, and dispensaries shall not sell or otherwise transfer any final harvest batch or final product to a dispensary until the product has undergone final product testing. For the purposes of this section, "final product" means the finished product that is available for transport to a licensed medical marijuana dispensary and ready for consumption by licensed medical marijuana patients. Final product testing shall only be required when the final product is completed and prior to transfer to a licensed medical marijuana dispensary, licensed medical marijuana patient, or licensed medical marijuana caregiver.

(e)Authority required testing. The Authority may require a medical marijuana commercial business to submit a sample of medical marijuana, medical marijuana concentrate, or medical marijuana product to a licensed testing laboratory or the quality assurance laboratory upon demand when the Authority has reason to believe the medical marijuana is unsafe for patient consumption or inhalation or has not been tested in accordance with Oklahoma law and these regulations. The Authority may also require a medical marijuana business to periodically submit samples of medical marijuana or medical marijuana products to the quality assurance laboratory for quality assurance purposes. The licensee shall provide the samples or units of medical marijuana or medical marijuana products at its own expense but shall not be responsible for the costs of testing.

(f)Prohibited transfers. Except as is authorized in these Rules, growers, processors, and dispensaries shall dispose of and shall not use, sell, or otherwise transfer any medical marijuana or medical marijuana products that exceed any testing thresholds or fail to meet any other standards or requirements set forth in this Subchapter.

(g)Embargo and recall.

(1)Embargo. In the event that any medical marijuana or medical marijuana product is found by an authorized agent of the Authority to fail to meet the requirements of 63 O.S. § 420 et al., or the Oklahoma Medical Marijuana and Patient Protection Act as it relates to health and safety, the medical marijuana or medical marijuana product is handled in violation of applicable laws or rules and regulations promulgated by the Executive Director of the Authority, or the medical marijuana or medical marijuana product may be poisonous, deleterious to health or is otherwise unsafe, the following shall occur:
