A COA is a crucial document that summarises the exact chemical makeup of a CBD product - so you know precisely what to expect from it. The law does not currently require CBD brands to supply their customers with these reports. However, reputable brands that take pride in their products are proactive in ensuring that copies of their certificates are available for you to review. Reading these reports can empower you as a consumer, and CBD brands that fail to provide COAs should be approached with caution.
