Testing Method
Look for information on the testing method used. The COA should specify if the product was tested using gas chromatography (GC) or liquid chromatography (LC), which are the most accurate and reliable methods for determining the contents of a CBD product.
Amount of CBD and THC
Check for the amount of CBD and THC. The COA should indicate the amount of CBD and THC in the product, as well as any other cannabinoids that may be present. If the product contains more than 0.3% THC, it’s considered a marijuana product and may not be legal in your state.
Levels of Impurities
Look for contaminants and impurities. The COA should indicate if the product contains any contaminants or impurities, such as heavy metals, pesticides, or solvents. Products that contain high levels of these substances may be harmful to consume.
Authenticity of COAs
Verify the authenticity of the COA. The COA should include the name of the laboratory that conducted the tests, as well as the name of the product and the batch number. You can verify the authenticity of the COA by contacting the laboratory directly.
