Pet Cannabis: Marijuana is federally designated as a schedule I controlled substance in the United States under the Controlled Substances Act. As cannabis-derived products have become more available, veterinarians have seen increased interest among clients in using these products for their pets. Cannabis-derived products that have been suggested as therapeutic agents for use in animals have not followed the traditional path to FDA approval. Relatedly, although cannabinoids such as CBD appear to hold therapeutic promise in areas such as the treatment of epilepsy and the management of pain and inflammation associated with osteoarthritis, the available scientific evidence pertaining to their use in animals is currently limited.
