What a COA can show
A COA may list CBD, THC, minor cannabinoids, batch information, test date, and screening for items such as residual solvents, pesticides, heavy metals, microbes, or mycotoxins. Not every report covers every category.
How to connect it to the product
The batch number or lot number on the product should match the lab report. If the COA is old, missing, or hard to connect to the item, compare other options.
What a COA does not prove
A lab report does not prove a product is right for every person. It is one quality signal, best used with label reading, brand research, local rules, and common sense.
