Halfway up Ben Nevis, Christina Bluhme's black Labrador, Tokyo, lost the use of her legs and drifted in and out of consciousness, prompting the Lochaber mountain rescue team to carry the unconscious 25-kilogram dog down Britain's highest mountain to a veterinary clinic. [1]

Bluhme said Tokyo recovered by the following day and reported that veterinarians believed the dog had ingested cannabis left on the trail, but the fetched record contains no toxicology, identified substance, dose, confirmed litter source or evidence naming whoever discarded it. [1]

BBC News preserved the decisive qualifier in its verified X post, saying the dog was suspected to have eaten discarded cannabis, careful wording that supports the rescue story without upgrading belief into laboratory confirmation.

Collapse, loss of balance and inability to stand require professional help rather than improvised diagnosis, and this case shows why an owner on a mountain may need both veterinary care and rescuers capable of moving an animal safely; the Guardian lists possible symptoms, but that list cannot identify Tokyo's exposure or prescribe care for another dog.

Tokyo's reported recovery is welcome but cannot establish cause, treatment efficacy or a general prevalence of drugs on hiking trails, so the service lesson is to seek help quickly and leave substance identification to qualified evidence, while recognizing that the mountain setting made ordinary transport impossible without trained help from the rescue team.
