The U.S. Food & Drug Administration (FDA) recently issued Warning Letters to five companies selling products containing delta-8 tetrahydrocannabinol (delta-8 THC) and cannabidiol (CBD). In addition to the various violations outlined by FDA in the letters under the Federal Food, Drug, and Cosmetic Act (FFDCA), the agency particularly highlighted its serious concerns about the potential health effects of delta-8 THC products. While this is the first time that FDA has ever issued Warning Letters for products containing delta-8 THC, we view this set of Warning Letters to signify FDA’s continuing enforcement of federal restrictions on the marketing and sale of products containing cannabis-derived ingredients.
The U.S. Food & Drug Administration (FDA) recently issued Warning Letters to five companies selling products containing delta-8 tetrahydrocannabinol (delta-8 THC) and cannabidiol (CBD) in ways that violate the Federal Food, Drug, and Cosmetic Act (FFDCA). 1 In these letters, the agency cited various FFDCA violations including the marketing of unapproved new drugs and the unlawful use of delta-8 THC and CBD in food and dietary supplement products. The agency also particularly noted its serious concerns with the potential health effects of delta-8 THC products.
In light of significant industry interest in the development of consumer products derived from cannabis and its components, FDA has reinforced its position that CBD cannot be legally sold as dietary supplements or in a food under the exclusionary clause. 2 In the recently issued Warning Letters, FDA similarly asserts delta-8 THC cannot be sold as a food. Along with the Federal Trade Commission (FTC), FDA has previously issued Warning Letters to various companies selling CBD products that claimed to diagnose, cure, mitigate, treat or prevent various diseases in violation of the FFDCA. Like CBD, delta-8 THC is also derived from the Cannabis sativa plant. While THC is a Schedule I controlled substance, delta-8 THC has not been listed by the Drug Enforcement Agency as a controlled substance. FDA describes delta-8 THC as a psychoactive substance and characterizes the amount of delta-8 THC from the plant as very low. In the Warning Letters, FDA expresses concern with the use of chemicals to convert other cannabinoids in the plant into delta-8 THC. FDA has not evaluated or approved any products containing delta-8 THC, nor are there any FDA-approved drugs containing delta-8 THC. Therefore, any delta-8 THC product claiming to diagnose, cure, mitigate, treat, or prevent disease is considered an unapproved new drug by the agency. In addition, like CBD, FDA considers delta-8 THC to be an unapproved food additive for use in any human or animal food product, as the substance is not generally recognized as safe (GRAS) or otherwise exempt from food additive requirements. FDA states it has serious safety concerns with delta-8 THC. FDA states it has received 104 reports of adverse events in patients who consumed delta-8 THC products between December 1, 2020 and February 28, 2022.
These new Warning Letters address a number of FDA concerns with the marketing and sale of CBD and delta-8 THC products. In particular, FDA highlighted the following –
The products receiving the Warning Letters made various statements identified by FDA as human drug claims, for example:
FDA also identified various statements as animal drug claims, for example:
FDA has requested written responses from the companies within 15 working days, and failure to promptly address the violations in the Warning Letters may result in legal action, including product seizure and/or injunction.
As the agency continues to enforce federal restrictions on the marketing and sale of cannabis products, interesting questions may arise concerning the relationship of this regulatory framework with conflicting state laws.
We will continue to monitor FDA’s response to cannabis products. Please do not hesitate to reach out to us on this or any other matter.
