USA Today reports:
Residents of Colorado and Washington state aren't the only ones getting high on legal marijuana: So are their four-legged friends.
The states' decision to legalize recreational pot is driving an increase in the number of dogs scarfing down marijuana-infused cookies, brownies and butters. Unlike humans who can metabolize marijuana in a few hours, dogs feel the effects far longer. The sight of a glassy-eyed dog sprawled on the floor or stumbling around frightens pet owners, veterinarians say.
"We see dogs stoned out of their minds for days. They're a mess," said Tim Hackett, director of the Colorado State University veterinary teaching hospital. "The pot goes in cookies and butters. Dogs love that stuff, and they won't eat just one."
