In cities were marijuana has been legalized, more people are smoking weed. And that means there are more joints on the ground for dogs to eat.

And now reports suggest the country could have a stoned dog epidemic.

In cities like New York City, more dogs are coming across — and eating — discarded joints and edibles, prompting alarm among veterinarians and pet owners who blame the steep rise in poisonings on smokers oblivious to the harm they can do by littering.

Poisonings, which are almost never fatal, were once rare among pets, even when medical dispensaries started opening, according to Dr. Amy Attas, a New York City veterinarian. Until recently, many occurred at home, when pets got into their owners’ stashes.
