One of the advantages of a licensed market is testing. In Oklahoma, medical cannabis must pass laboratory testing before it reaches you — and the results live in a document called a Certificate of Analysis.
What gets tested
A licensed lab checks two broad things:
- Potency — how much THC, CBD, and other cannabinoids the product contains.
- Safety — screening for contaminants such as pesticides, microbials (like mold), heavy metals, and residual solvents left over from extraction.
The Certificate of Analysis (COA)
A COA is the report for a specific batch. It confirms the potency printed on the label and shows that the product passed its safety screens. The batch number on the package ties back to its COA.
Why it matters
Testing is the difference between a regulated product and the unregulated market. It’s also why the numbers on the label mean something. Shop tested products from licensed dispensaries — find one near you in the directory.
