How to Read Cannabis Oil Lab Results (COA)
A Certificate of Analysis (COA) is your proof that a cannabis oil is what it claims to be. Learning to read one is the single best way to protect yourself as a buyer. Here is what to look for.
Cannabinoid profile
The COA lists the concentration of cannabinoids such as THC, CBD, CBN, and CBG. Check that the potency matches the product label. For RSO, expect high THC percentages; for balanced FECO, look for the stated THC:CBD ratio.
Safety testing
- Residual solvents - should be within safe limits or non-detected
- Pesticides - should pass all screened categories
- Heavy metals - lead, arsenic, cadmium, and mercury should be within limits
- Microbials - screening for mold, yeast, and harmful bacteria
Verifying authenticity
A trustworthy COA comes from an accredited, third-party lab and includes a batch number that matches your product. If a seller cannot provide a current COA, treat that as a red flag.
