The Association of American Feed Control Officials (AAFCO), which approves pet food ingredient definitions, addressed the issue at its January 2017 meeting, Dzanis said. “AAFCO has subsequently issued guidelines to note that to date, no hemp-based ingredients have been defined or otherwise sanctioned for use in animal feed, hence any inclusion in a feed or pet food would be objectionable to state feed control officials.”
The American Veterinary Medical Association does not have an official stance on medical marijuana, but cannabis is not FDA-approved for pets. Furthermore, in any given state (even legal states with booming cannabis markets like Colorado), veterinarians are banned from writing prescriptions for cannabis products. In 2015, a bill introduced in the Nevada state legislature that would have allowed pet owners to feed medical marijuana to sick pets was shot down.
