What is a Certificate of Analysis (COA)?
A Certificate of Analysis, or COA, is a document from an accredited laboratory that shows the quantity of various cannabinoids in a product. Manufacturers should send every batch of every product they make to a lab for testing, to protect their customers and prove that their products have as much CBD as they advertise.
Always check the COA before purchasing a CBD product
COAs aren't always easy to get your hands on before buying a product. You may need to reach out to the company to request it. As of July 2019, all major credit card processing companies and bank underwriting departments require that CBD sellers publish their COA's online. If the company you're considering buying from does not have their COA published online for inspection; buyer beware.
