Lab reports help medical cannabis patients verify potency, review safety testing, and make more informed choices about the products they use.

What a COA is (and why it matters in cannabis Florida)

A COA is a third-party lab report tied to a specific batch (also called lot) of a product. It typically covers two big things:

1. Potency (cannabinoids like THC/CBD, sometimes terpenes)

2. Safety (screens for contaminants like pesticides, heavy metals, microbials, residual solvents, etc.)

In Florida’s medical program, testing labs are certified through the state’s Office of Medical Marijuana Use (OMMU), and OMMU publishes a list of certified marijuana testing laboratories (CMTLs).
