Can Animals Consume Cannabis

Animals often have curious noses, which leads them to eating all sorts of things that aren't good for them. Sometimes that thing happens to be your cannabis stash and unfortunately for them, it is unlikely to go down well. This article discusses how to deal with an intoxicated pet and whether cannabis is safe for animals in general.

Cannabis And Animals

Endocannabinoid System In Cats And Dogs

Cannabis consumption may very well be enjoyable for humans, but for animals it's a whole different story. Firstly, it is never a smart idea to purposely get an animal high. This is both cruel and potentially dangerous or life threatening for the animal. They are unlikely to have a good time and it won't be funny for you if you suddenly need to make an emergency visit to the vet.

If you're lucky, the animal may just pass out and sleep it off. On the other hand, it could cause some pretty erratic and confused behaviour or even death, so if you consume cannabis and have pets it is of utmost importance you keep them away by protecting and storing your cannabis safely.

Animals such as cats and dogs have an endocannabinoid system similar to our own. This means they can react to THC and will get high from even low doses. 

There are plenty of ways an animal can find its way to your stash. The most likely situation is that the animal ate some tasty edibles, as they aren't usually drawn to eating cannabis on its own, although it can happen. Either way, you need to be conscious of where you leave your bits otherwise they may have disappeared the next time you go to collect them.

The Effect Of Cannabis On Cats and Dogs

The Effect Of Cannabis On Dogs and Cats

Like for humans, the effect of cannabis on animals depends on how it is consumed and in what quantity. If your pet ate raw cannabis, the THC will not yet have been activated and therefore will have a weaker effect than if the weed was decarboxylated beforehand by making edibles.

  • Raw Cannabis
  • Dried Cannabis
  • Decarboxylated Cannabis
  • Edibles
  • Concentrates

Animals can also get high from second hand smoke. This means it's important to be considerate of any animals present and at the very least you should make sure there are windows open and fresh air replenishing the space so you don't end up hotboxing your furry friend.

Effects Of Cannabis On Cats

Cats and Cannabis

Cats are not known to be particularly attracted to cannabis, and make up a small portion of the reported cases. However, it does happen that cats decide they want to have a go on your tasty greens or unintentionally inhale second hand smoke. A study based on a Persian cat in Poland was reported to have ingested cannabis smoke and displayed some extreme, strange behaviour, symptoms of which included having repeat attacks of disorientation, aggression, no appetite, and various other odd reactions.

Cats are generally smaller than most dogs and less THC can affect them much more intensely. The exact lethal amount for cats is still not clear.

Effects Of Cannabis On Dogs

Dogs and Cannabis

Anyone who has had a dog before is likely to know how much they love food. This is why most of the cases come from dogs accidentally eating edibles. In fact, around 96% of the reports are related to dogs. They are very sensitive to THC, and if you're not careful they might gobble up the whole stash when given the chance.

If your dog has sniffed its way into the cannabis edibles you have prepared or bought then you may want to seek professional help unless you're sure the dose is low enough to be safe (the lethal dose for dog orally is said to be around 3 grams per kilo of body weight). Even so, monitor your dog's behaviour so you know whether the reaction is serious or potentially dangerous.

Does CBD Work For Animals?

CBD For Animals

Many pet owners have given CBD to their pets as medicine and seen it to improve their health with no bad side effects. There is still a lot being studied in this field, but CBD is being discussed as a potential treatment for anxiety, seizures and pain in animals.

There are many different CBD products labelled as safe for animals designed to aid their well being, however it is best to discuss any treatments with your vet beforehand. 

What To Do If Your Pet Eats Cannabis

What To Do If Your Pet Eats Cannabis

In the event that your pet has consumed some cannabis, the first thing to do is stay calm. Figure out exactly what and how much of the cannabis it has consumed before taking action.

Steps to take if your pet eats cannabis:

  1. Stay calm - If you stress out, your pet could get even more confused and you also might not be thinking straight.
  2. Find out how much has been consumed and in what form - Calculate the dosage so you know whether it's going to be necessary to take the animal to the vet.
  3. Look for symptoms in the animal - gauge how your pet is reacting to the cannabis. Edibles will take longer to see effects.
  4. Induce vomiting - Very unpleasant for the animal, but if it has ingested a large amount of cannabis orally, you can consider making it throw up.
  5. Take it to the vet - Seeking professional advice is maybe the best option if you're really concerned your pet might have consumed too much cannabis.

Keeping Pets Safe From Cannabis

Keep Cannabis Materials Out Of Reach

Knowing your pets and their tendencies will help you establish a system of trust, so only you will know whether it is safe to leave your pet unattended with some cannabis in the room. It can be easy when you're high to forget about things left on the coffee table at dog level, or passing out on the sofa with the bag of cannacookies at easy reach.

The edibles are where you need to be most careful, as they have the most attractive smell to the majority of animals that might consume them. They are also potentially the most worrying if they do become ingested, because the THC is activated, making it much more intense for the animal. At the same time, the high can last for a lot longer. It goes without saying, but remember to keep your cannabis edibles out of reach of pets.

Open Window Vs Smokey Room

There are a few things you can be conscious of when preventing your pets from consuming any of your cannabis, whether through inhaling smoke or oral consumption.

  • Keep your indoor plants in separate space with a closed door or for outdoor plants, fencing or a greenhouse.
  • Consume your cannabis in a different room and make sure there is enough fresh air.
  • Make a habit of always clearing your stash up and leave it out of reach.

J'ai eu un chat qui était très attiré par les plantes de cannabis et après en avoir consommé, j'ai constaté une agitation anormale, des pupilles dilatées et pour finir des vomissements. Le cannabis était frais et pas du tout décarboxilé... Il avait du manger trois ou quatre feuilles en éventail. Mais il cherchait par tous les moyens à se réintroduire dans la chambre de culture, malgré sa " mauvaise expérience"... J'en avais parlé à des amis qui m'ont confirmé que les chats et les animaux en général adorent cette plante, tout comme nous en fait. Peaaaaaaaaaace.
Cool pig
thx ;)
