LOS ANGELES (CBSLA) — The federal government warned 15 companies Monday suspected of illegally selling products containing an ingredient usually found in marijuana — cannabidiol or CBD — in ways that violate the Federal Food, Drug, and Cosmetic Act.

The Food and Drug Administration sent letters to the companies it said were marketing CBD for therapeutic use, treatment for illnesses or dietary supplements.

The FDA also said it could not conclude that CBD was safe for use in human or animal food based on the lack of scientific information on the non-psychoactive ingredient.

“Today’s actions come as the FDA continues to explore potential pathways for various types of CBD products to be lawfully marketed,” the agency said in a statement. “This includes ongoing work to obtain and evaluate information to address outstanding questions related to the safety of CBD products, while maintaining the agency’s rigorous public health standards.”
