Why it is toxic

THC; concentrated edibles and extracts are far more dangerous than plant material

How fast symptoms appear: 30 minutes to 3 hours, longer with edibles

Symptoms of poisoning
  • Wobbly gait
  • Dribbling urine
  • Glazed, dull responsiveness
  • Startling at sound or touch
  • Slow heart rate
  • Low body temperature
What to do first
  1. Tell the vet honestly what and how much was eaten — the consultation is confidential and accuracy changes the treatment.
  2. Check whether the edible also contained chocolate, xylitol or raisins, which are separate poisonings.
  3. Keep your pet warm and quiet on the way in.
What your vet will do
Supportive care, intravenous fluids, warming and anti-sickness medication; intravenous lipid therapy is considered in severe cases.
