Laws regarding veterinarians' rights to discuss cannabidiol products with clients vary from state to state, and veterinarians should check with their malpractice insurance carrier, state licensing board and AVMA resources before discussing, prescribing or selling CBD products for veterinary use, says veterinarian and attorney Charlotte Lacroix. Some states have legalized CBD, but the federal government has not, and the FDA has not approved any CBD-based medicines or dietary supplements for veterinary use.
