A certificate of analysis (COA) is a document that provides detailed information about the composition, quality, and safety of a particular cannabis product. In the cannabis business, COAs are typically issued by third-party testing laboratories to ensure that the product meets certain standards and regulatory requirements.
A COA typically includes information such as the product's cannabinoid profile (including THC and CBD content), terpene profile, potency levels, and potential contaminants (such as pesticides, heavy metals, and residual solvents). It serves as a means of verifying the accuracy of product labels and ensuring that consumers are aware of what they are purchasing.
