Studies & Evidence
What veterinary experts and published sources say about cannabis toxicity in pets.
🌿 The science behind cannabis toxicity in pets
As cannabis use becomes more widespread, veterinary hospitals across North America are reporting a sharp increase in accidental cannabis poisonings in dogs and cats.
THC affects pets differently than humans. Even trace exposure can overwhelm their nervous system and lead to frightening symptoms such as disorientation, paralysis, or blindness.
💚 How pets are exposed
- Eat discarded roaches or edible crumbs
- Chew dried cannabis or packaging
- Inhale secondhand smoke
Because THC is fat-soluble, it’s absorbed into tissues — symptoms can last hours or days.
🐾 Symptoms & duration
- Signs: 30 minutes to 2 hours
- Effects may last 12–72 hours
- Dogs affected more often than cats
- Unsteady walking or falling
- Tremors or twitching
- Glassy eyes or dilated pupils
- Urinary dribbling
- Vomiting
- Lethargy or disorientation
- Heightened sensitivity
Severe cases: seizures, coma, collapse — smaller pets are at the highest risk.
🌿 Diagnosis & treatment
- IV fluids
- Monitoring of temperature & heart rate
- Sedatives or anti-seizure meds
- Activated charcoal
Most pets recover within 24–72 hours with prompt veterinary care.
📈 Rising trend
Poison control calls have increased significantly since legalization — many veterinary hospitals see multiple THC toxicity cases per week.
🩵 The takeaway
Cannabis toxicity in pets is preventable.
Dispose responsibly. Store securely. Educate others.
Protect Pets. Prevent Harm.
