COA

A Certificate of Analysis, the lab document showing a cannabis product's cannabinoid content, terpene profile, and screening for pesticides, heavy metals, and microbes. A current COA from an accredited lab is the single best proof that a product is potent and safe. Reputable brands make their COAs easy to find.
