The only CBD pharmaceutical approved in the U.S. (Epidiolex®) is approved only for two rare types of epilepsy. Nonpharmaceutical CBD products are widely available, but they often contain a lot more or less CBD than stated on the label, and even sometimes some THC.[1][2]
CBD products might also contain some of the same contaminants frequently found in cannabis: metals, molds, bacteria, pesticides, aflatoxins, synthetic cannabinoids,[3][4] and residual solvents from the production process (hexane, benzene, xylene, toluene, acetone, ethanol, and isopropyl alcohol).[5]
