Since the use of cannabis has become legal in Canada and the United States, there has been an increase in the number of pets who have suffered cannabis poisoning. Researcher Richard Quansah Amissah of the Ontario Veterinary College at the University of Guelph in Ontario, Canada, and colleagues have conducted a study of this problem.
Although most of the animals that suffered from cannabis poisoning were dogs, the other pets included, cats, iguanas, ferrets, horses and cockatoos. Most of the poisoning was due to the pets eating cannabis edibles.
The symptoms (mostly in dogs) included urinary incontinence, disorientation, and a slow heart rate. Most pets were treated as outpatients and recovered. Although some died, it is not clear if there may have been underlying medical issues that contributed to the death of the pet.
Authors Note: Cannabis edibles should be treated as any other drug and kept in a safe place where pets, children and other adults who are not authorized to use cannabis, cannot ingest the products.
