A rescue team was summoned to the tallest mountain in Scotland to rescue a Labrador that became ill after consuming marijuana.

Christina Bluhme said her five-year-old black lab, named Tokyo, started showing symptoms during a family hike near the peak of Ben Nevis.

“We were maybe an hour from the top when we noticed Tokyo got really weak in her hind quarters,” Bluhme told CNN.

“Initially, I thought it could have been a spinal thing or a disc that had slipped because of the climb, but then she started drifting in and out of consciousness. I was standing on that mountain thinking that that was it, I was going to lose her,” she said.

Efforts to carry 53-pound Tokyo down the mountain were hampered by heavy rains, leading the family to call for help from the Lochaber Mountain Rescue Team, which happened to have volunteers nearby after dealing with another emergency.

Tokyo was carried down the mountain on a stretcher and Bluhme then took her to Crown Vets in Fort William, where the cause of her condition was discovered.

“She had all the symptoms of consuming cannabis and had her blood tested too. What really gave it away was when she had her temperature taken she let out some gas and it smelled completely like cannabis. It was almost like standing beside someone smoking weed,” Bluhme said.

“It’s not funny, but it was a bit funny,” she said.

Veterinarians said Tokyo likely ate a cannabis edible that had been left on the trail, or human waste from a marijuana user.

Tokyo was able to go home the following day and is doing much better, her owner said.

“She was wagging her tail very happily and was ready to go. And the day after you wouldn’t have thought that this had happened to her,” she said.
