What is a Certificate of Analysis?
A COA is an independent lab report that verifies cannabinoid potency, terpene profile, and product safety. CannaCompare publishes every available COA so customers can verify quality before they buy.
Cannabinoid potency
Exact THCa, Δ9-THC, CBD, CBG, and total active cannabinoid results for each batch.
Terpene profile
Flavor and effect markers that show how the strain smells, tastes, and performs.
Safety screening
Pesticide, heavy metal, solvent, and microbial pass/fail results are clearly displayed.
Batch traceability
Every COA links to a unique lot number so you know it matches the product in your hand.
How to read a COA
COAs can feel technical at first. This guide explains the most important values so you can quickly understand what matters.
THCa %
THCa is the raw cannabinoid before heat converts it into Δ9-THC. Higher THCa means stronger effects when consumed.
Delta‑9 THC %
Hemp products must contain 0.3% Δ9-THC or less by law. Your COA should show this clearly and exactly.
Total active cannabinoids
This number gives you the overall potency picture by summing all detected cannabinoids.
Terpene profile
Terpenes shape aroma, flavor, and effect. The most common markers are myrcene, limonene, caryophyllene, and linalool.
Earthy and herbal, often linked to relaxing effects.
Citrus-forward, bright, and energizing.
Spicy and peppery with calming undertones.
Floral and soothing, often associated with calm.
Safety panels
Verify PASS results in every category: pesticides, heavy metals, solvents, and microbials.
No harmful agricultural chemicals detected.
Lead, arsenic, cadmium, and mercury are within safe limits.
Clean extraction results for concentrates and carts.
Free of mold, yeast, and harmful bacteria.
