Marijuana and its effects

Marijuana (cannabis) and its derivatives, such as hashish and oils, are potent psychoactive substances obtained from hemp. Tetrahydrocannabinolic acid is converted into THC after the drying process, a psychotropic compound that acts directly on the central nervous system and the brain.

It usually causes euphoria, relaxation or appetite, however, this plant also causes side effects such as anxiety, dry mouth, reduced motor capacity and weakness.

There are also other effects of marijuana in dogs:

  • Exposure by chronic inhalation of marijuana may induce bronchiolitis (respiratory infection) and pulmonary emphysema.1
  • Moderately decreases the frequency of the dog's pulse.
  • A too high oral dose could lead to the death of the dog due to intestinal bleeding and at the same time, an excessive intravenous dose could lead to death from pulmonary edema.3

Symptoms of hashish or marijuana intoxication in dogs

Marijuana usually acts 30 minutes after being ingested, but in some cases it can take up to an hour and a half later and last for more than a day. The effects it causes on the dog's body can become serious and although marijuana itself does not cause death, the symptoms it causes do.

Symptoms that we can observe in case of intoxication:

  • Tremors
  • Excessive salivation
  • Vomiting
  • Diarrhea
  • Abnormal dilation of the eyes
  • Glassy eyes
  • Difficulty coordinating movement
  • Disorientation
  • Drowsiness
  • Hypothermia

The heart rate during marijuana intoxication may become slower, so it is important to remember that heart rate is above 80 and 120 beats per minute. Small breeds must have a higher rate and larger breeds lower.

In addition, they may show signs of depression, or heightened excitement.

How to treat poisoning

Here's a step-by-step first aid that can be used to treat hash poisoning in your dog:

  1. Call your veterinarian, explain your situation and follow their advice.
  2. Make your dog vomit if not more than 1 or 2 hours have passed since the consumption of hashish.
  3. Try to relax your dog and observe all symptoms present during this process.
  4. Check your dog's mucous membranes, take their temperature and make sure they are breathing properly and have a normal heart rate.
  5. Ask a family member to go to the pharmacy to buy activated charcoal, an absorbent and porous product that prevents the absorption of the toxic substance in the stomach.2
  6. Go to the vet.

If from the beginning you notice that your dog drastically lowers their temperature or that the effects cause them excessive discomfort, go to the veterinarian immediately. Perhaps they will need a gastric lavage and even hospitalization to keep your vital signs.
