A new document available exclusively to American Veterinary Medical Association members provides comprehensive background information to help veterinary professionals understand the legal aspects of cannabis use in animals; field questions and advise clients who are interested in marijuana therapies for their pets; and identify toxic exposures. Cannabis: What Veterinarians Need to Know addresses such topics as the legal status of medicinal marijuana in veterinary medicine, how cannabinoids function, marijuana risks to pets, clinical signs and treatment of acute marijuana toxicosis, and effects of chronic marijuana exposure. Available on the Cannabis Use and Pets page of the AVMA’s website, the document is the first in a series of related materials the association is developing as a resource for its members. Future tools will include information on medicinal marijuana in pets, and educational materials clinicians can share directly with clients.
