A certificate of analysis is a lab report on the chemical properties of the product being tested. In the case of cannabis, the COA will report on the cannabinoids, terpenes and contaminants present or absent in the product. The COA will verify if the CBD product has the legal amount of THC (less than 0.3% by weight). They will also check for dangerous substances and compounds that can be found in CBD products, such as heavy metals, residual solvents, microbes, and pesticides. If you have any questions regarding our COAs, please reach out. We are happy to help talk through them!
