Since the 2018 Farm Bill passed in December 2018, removing hemp from the Controlled Substances Act and thus legalizing it under federal law, consumer goods containing the hemp-derivative cannabidiol (CBD) have become exceptionally popular. With that growing popularity among consumers has come increased scrutiny by federal regulators whose mission is consumer safety and protection, such as the Food and Drug Administration and Federal Trade Commission, and now by the plaintiffs’ bar, which files consumer class actions based on advertising. As the recent spate of warning letters and consumer class actions demonstrate, hemp-derived CBD product manufacturers and others in the supply chain for those products have to be mindful of the claims they make to consumers about their products.
