Q: Is marijuana bad for your pet?

A: According to experts, marijuana can be harmful to your pets.

From an article out of the College of Veterinary Medicine at the University of Illinois Urbana-Champaign:

Both dogs and cats can be poisoned by tetrahydrocannabinol (THC), the psychoactive substance in marijuana. Dogs are more likely to ingest the drug, while cats are more likely to be sickened by exposure to smoke.

In dogs, the most common signs of marijuana intoxication include dribbling urine, swaying or general unsteadiness, drooling, and being less alert. Cats will show signs that mimic those of neurologic disease, such as appearing to react to visual stimuli that are not actually present. They may also have dilated pupils.
