There are no other FDA-approved drugs that contain CBD. The FDA has received reports of some CBD products containing contaminants such as pesticides and heavy metals, raising additional concerns for the use of CBD products. Unlike the FDA-approved CBD drug, unapproved CBD products, which could include cosmetics, foods, products marketed as dietary supplements, and any other product (other than Epidiolex) that make therapeutic claims, have not been evaluated by the FDA as to whether they are effective to treat particular disease or have other effects that may be alleged. Because CBD is an unapproved drug, the FDA has not had the opportunity to evaluate CBD residues in food or to establish an adequate abstinence period.
We still don't have clear answers to important questions, such as what adverse reactions may be associated with CBD products and what risks are associated with long-term use of CBD products. This is an important component of the FDA's work because little is known about the amounts of CBD and several related cannabinoids, as well as the presence of toxic elements, pesticides, other potential chemical contaminants and adulterants, which may be present in CBD products marketed to consumers.
