Key quality control aspects about cannabinoid-rich hemp products that a veterinarian needs to know: a practitioner's guide.

There is considerable confusion in the veterinary profession surrounding the rise in hemp cannabidiol-based animal products and what veterinarians should know before discussing these products with clients. There is emerging evidence for the potential use in case management across many veterinary indications; however, the cannabinoid concentrations and whether these are isolated cannabinoids or whole hemp extracts is difficult to elucidate, even from the published papers. Much like any extract from a plant, there are multiple considerations including quality control, pharmacokinetics in the intended species, microbiological and chemical contamination, and product consistency-all aspects that should be considered before a conversation can begin with a client. The aim of this review is to help practitioners make informed decisions and better facilitate discussions with clients for companion animals kept as pets. This review will not address food animal issues, as established withholding times have yet to be fully researched.
