More pets are being poisoned by marijuana plants and
edibles than in the past, and some even die, according to a new study.
The study, which was
published Wednesday in the journal
PLOS One, surveyed veterinarians in Canada
and the United States.
The study found cases of cannabis poisoning occurred
most frequently in dogs, but other animals suffered too, including ferrets,
cats, iguanas, cockatoos and horses.
The study found most pets
recovered, sometimes after 24 to 48 hours in a veterinary hospital, but 16 dogs
died after ingesting marijuana.
But study author Jibran
Khokhar said it's hard to know if the deaths were related to the cannabis or
other ingredients in a cannabis edible, such as chocolate.
