What is this product?

CBD (cannabidiol) oil has become a multi-billion-dollar consumer product marketed for anxiety, pain, sleep, and inflammation, available as tinctures, capsules, gummies, topicals, and pet products from thousands of manufacturers operating in a largely unregulated market. Despite the 2018 Farm Bill legalizing hemp-derived CBD, the FDA has not approved CBD as a food additive or dietary supplement (Epidiolex remains the only FDA-approved CBD product, for epilepsy). This regulatory vacuum has created systematic quality control failures: a landmark 2017 JAMA study found that 69% of CBD products tested were mislabeled — 43% contained less CBD than claimed and 26% contained more, while 21% contained detectable THC not disclosed on the label. Contamination with pesticides, heavy metals, residual solvents, and synthetic cannabinoids has been documented in multiple independent surveys. CBD is not pharmacologically inert — it is a potent inhibitor of cytochrome P450 enzymes (CYP3A4, CYP2C19, CYP2C9, CYP1A2), causing clinically significant interactions with warfarin, clobazam, valproate, immunosuppressants, and many other medications. FDA-approved Epidiolex carries a black box warning for hepatotoxicity at doses above 10 mg/kg/day, and liver enzyme elevation has been documented in clinical trials.
