Certificates of Analysis

A certificate of analysis (COA) is a document associated with cannabis-derived products, attesting to its laboratory analysis for cannabinoids and in some cases adulterants, heavy metals, pesticides, mold, etc. In the United States, as of 2020, COAs are voluntary for CBD products unless purchased at a cannabis dispensary, in some states.[1] According to one nutritional text, a certificate of analysis is "an easy way to review test results from responsible companies selling cannabis and cannabis-infused products".
