Oklahoma: from grow to patient, what the label has to prove

Step by step: Oklahoma

1. Step 1: Harvest batch, 15 lb max (Grower) A licensed grower splits the harvest into batches of 15 pounds or less (up to 50 lb if it is headed for extraction) and logs each in Metrc, the state’s seed-to-sale system. This becomes the label’s batch number and the grower name and license number.
2. Step 2: A sampler pulls two samples (Sampler (lab or licensee)) In Oklahoma the sampler can be employed by the lab, the grower, the processor or the dispensary, as long as they follow the testing lab’s written procedure. On site they collect 0.5% of the batch, split it into a primary and a reserve sample of at least 5 g each, seal both tamper-evident, and deliver them to the lab the same day.
3. Step 3: Up to nine test categories (Testing lab) An OMMA-licensed lab, accredited through a body that belongs to the International Laboratory Accreditation Cooperation, tests flower for potency (11 named cannabinoids), terpenes, microbes including four Aspergillus molds, pesticides, heavy metals, filth and foreign matter, and water activity and moisture. Processed products such as extracts add mycotoxins and residual solvents. Owners of growers, processors or dispensaries may not own a lab.
4. Step 4: High-THC flower gets a second look (Testing lab) Flower that tests at 30% total THC or more must be retested before the result is reported. At 32.5% or more, the rules have OMMA collect fresh samples from the batch and run its own potency check, a step tied to its new Quality Assurance Laboratory.
5. Step 5: COA issued, uploaded to Metrc (Testing lab) The lab issues the COA to the grower within two business days of its review, with Pass or Fail in at least 12-point type, and submits it into Metrc. This unlocks the label’s THC potency and total terpenoid content.
6. Step 6: Pass / fail (OMMA) A failed batch can be retested from the reserve sample, but it then needs two passing retests in a row; otherwise it is remediated, decontaminated or destroyed. Flower that fails for microbes may be turned into a solvent extract, which must pass the full panel again.
7. Step 7: Pre-packed and labeled (Grower) Since June 2025 flower must reach the dispensary already packaged, 0.5 g to 3 oz. The label adds the red Oklahoma Uniform Symbol (at least ½″ × ½″), the THC from that batch’s COA, the packaging date, “This product has been tested for contaminants.” and four warnings. A potency claim more than 15% off the COA counts as inaccurate.
8. Step 8: Dispensary and patient (Dispensary) The dispensary must refuse mislabeled product, may add barcode or QR inventory stickers as long as they cover nothing required, sells only to licensed patients and caregivers, and must produce the COA for any product in stock when a patient asks. Purchases leave in a child-resistant exit package.
