On July 22, the FDA issued a Warning Letter to Curaleaf with regard to Curaleaf’s “CBD Lotion,” “CBD Pain-Relief Patch,” “CBD Tincture,” and “CBD Disposable Vape.” The Warning Letter explains FDA’s view that Curaleaf’s CBD products are effectively “unapproved new and misbranded human drug products” because the claims Curaleaf has made about them on Curaleaf’s website and social media accounts demonstrate “they are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease and/or intended to affect the structure or any function of the body,” but Curaleaf has not obtained prior approval from the FDA to market them as such. The Warning Letter also explains the FDA’s view that the subject products are not “dietary supplements” because (i) CBD has already been approved as an active pharmaceutical ingredient (epidiolex), (ii) CBD was not marketed as a dietary supplement or a conventional food prior to such FDA approval of CBD as an API; and (iii) the subject products are not “intended for ingestion,” which is a requirement of a dietary supplement. The FDA also warned about Curaleaf’s products with respect to animals, which I have not summarized. The FDA provided Curaleaf 15 days to establish a corrective action plan and to report such plan to the FDA. The Warning Letter demonstrates the FDA is actively monitoring CBD manufacturer websites and social media for over the line claims, and that CBD manufacturers need to follow the FDA’s guidance given the unsettled regulatory structure with respect to CBD.
