Marijuana Toxicity in Cats
Many pet owners want to know if their cat will experience any issues when inhaling second-hand pot smoke, eating marijuana brownies, or chewing on the leaves of the plant. While several cat owners out there think marijuana is just another form of catnip, it’s true that there is a drastic difference.
Catnip and Marijuana
Catnip is a plant that comes from the mint family. The perennial herb has downy leaves, purple-spotted white flowers, and a pungent smell that makes cats go crazy when smelled and sleepy when eaten. Marijuana, on the other hand, comes from a plant called Cannabis sativa. The chemical in Cannabis that produces the altered states of consciousness humans enjoy is called Delta-9 Tetrahydrocannabinol or THC.
Marijuana is sometimes prescribed for relief from pain and nausea due to chemotherapy in cancer patients, and for certain conditions in AIDS patients. However, it’s still questionable whether there is anything beneficial in the plant for feline friends. In fact, it is strongly suggested that cats do not come close to any smoke from marijuana use, or any other smoke from cigarettes, cigars, or pipes.
How Cats Are Exposed to Marijuana
The most common ways cats are exposed to marijuana is by inhaling smoke or ingesting dried marijuana. Although people who have experimented with smoking catnip become happy and relaxed, cats should not be forced to “smoke” any substance.
Because of the cumulative effects of inhaling any kind of smoke, it is inadvisable to smoke marijuana anywhere near a cat, particularly one with asthma or other lung diseases. It’s important to be mindful of this, as humans are able to make educated decisions around topics like these, while cats are not.
In some cases, cats may nibble on the leaves and/or buds of the growing marijuana plant. Humans may also feed their cats cookies or brownies made with marijuana. This is a double whammy of injury to the cat, as the brownies and/or cookies may also contain chocolate, which is toxic to cats on its own.
According to the American Society for the Prevention of Cruelty to Animals (ASPCA), your cat may experience extreme sleepiness or excitation, hypersalivation, dilated pupils, or low blood pressure. There may also be instances of low body temperature or even death (although it’s rare). Additional symptoms most commonly observed include:
- Uncoordination, falling over
- Depression, sometimes alternating with agitation or anxiety
- Bradycardia (slow heart rate)
- Seizures, sometimes coma
If your cat demonstrates any of the symptoms above, you should take it to the veterinarian as soon as possible.
- If you have reason to believe your cat was exposed to marijuana smoke or has ingested marijuana in any form, it’s important to mention this to the vet. Quick treatment may ameliorate the most severe symptoms, and even save your cat’s life.

Medical Marijuana for Painful Conditions
The American Veterinary Medical Association (AVMA) publishes several articles about marijuana treatments and drug monitoring programs for animals. In 2017, AVMA House of Delegates members urged the Association to develop policies and guidance around marijuana treatments at the Veterinary Information Forum. One of the topics discussed included the increase of toxicity cases. Delegates like Dr. Dick Sullivan encouraged more research to be performed and for the national association to write to or petition the FDA in order to address marijuana issues to clients.
One article published in June 2013 tackled veterinary marijuana and pet owners who are looking to legalize marijuana for painful symptoms of the disease. The article quoted a woman who owned a 12-year-old labrador-retriever type of dog which had a tumor of the spleen metastasized to his liver and lungs. Unfortunately, the dog had been given two months to live, and the tramadol given for the pain was not doing the job. Of course, the poor dog was obviously in pain and completely inactive.
Because California legalized marijuana for humans, the dog’s owner was able to buy a glycerin tincture of marijuana that’s sold as a pet medicine in licensed medical marijuana dispensaries throughout Los Angeles. The dog’s improvement in activity and the easing of pain was such that the pet owner recommended the drug to other dog owners.
Under the same circumstances, it’s understandable that many pet owners wouldn’t hesitate to give medical marijuana to their own cats if it were available in their state. Thus, there needs to be more research and medicines available for cats experiencing pain.
Until it’s legal for vets to prescribe Cannabis to pets, they won’t have the authority to prescribe the drug. Overconsumption of THC may also create serious health risks in cats. However, hemp-based treatments high in Cannabidiol (CBD) can help. With more research, it’s possible that there is a dosage that can help cats with conditions like Inflammatory Bowel Disease (IBD), pancreatitis, arthritis, asthma, and cancer.
There are HempRx vitamins and oils that can act as a medication or supplement for your cat. Additionally, there are holistic and integrative veterinarians who can work with you to find the right product for your cat.
Pet owners want to know if marijuana is toxic to cats. See whether eating the leaves of the plant or inhaling second-hand smoke makes a difference.
Can My Pet Get High from Secondhand Marijuana Smoke?
by Jenn Keeler – August 3, 2017
Secondhand smoke is part of marijuana – walk into most any concert and you’ll find this to be true. The unmistakable smell of pot greets you, its wispy cloud calling you over like a curved finger. This isn’t really that big of a deal – it might annoy people who don’t like eau de skunk, but it’s not likely to get you high. In fact, studies show that people exposed to secondhand smoke can get stoned, but it takes a lot of exposure combined with little ventilation.
Yet, what about pets? One of the reasons people don’t get high so easily is their size: the average person in North America weighs 177 pounds. Dogs and cats are much smaller, which allows them to get higher easier. But, is this the case? Does hitting the pipe around Piper leave her purring for pepperoni pizza?
Secondhand Tobacco Smoke and Pets
The effect of secondhand tobacco smoke on people is controversial: some studies link it to health problems (ranging from heart disease to asthma to eye issues), others don’t. Still, nonsmokers embrace the no-smoking ban found in restaurants and public places – even if it doesn’t cause chronic health issues, it causes acute irritation. And, in all probability, hanging around loads of secondhand smoke (and inhaling the handed down carcinogens) can’t be good for you.
It turns outs, it’s not good for animals, either
According to Pet MD, a 2002 study found that cats exposed to secondhand smoke (or thirdhand – the kind that lingers in couch cushions and curtains), developed malignant lymphoma at a rate of nearly 2.5 times the cats that lived with owners who didn’t smoke. For cats who lived more than five years in a smoke-filled environment, the risk of lymphoma was threefold.
This same study also found a correlation between oral cancer in cats and thirdhand smoke, something that may be the result of cats grooming themselves with paws covered in toxins.
Dogs suffer from this type of smoke as well – two studies conducted in the 1990s found that dogs that lived in smoky households had higher rates of cancers in the respiratory tract. Where in the respiratory tract was dictated by the shape of the dog’s head – collies with long noses had higher risks of nasal cancer while dogs with shorter noses experienced lung cancer at increased rates.
While there appears to be a link between secondhand tobacco smoke and illness in pets, what about cannabis smoke?
Whether or not cannabis is healthy when overtly smoked isn’t known – on one hand, marijuana contains cancer-fighting cannabinoids. On the other, smoking anything introduces chemicals that you don’t want. Even smoking a piece of kale probably isn’t healthy.
That’s why many opt to vape – it filters out much of the bad stuff while keeping in much of the good.
Vaping around your pet is safer for them (and for you) than smoking a joint. But what happens if you do the latter? Will your dog laugh at everything you say and engage in introspective thinking: Why do I turn around three times before laying down? Or will they just go on with their regularly scheduled programming (i.e., napping and begging for food)?
Secondhand Smoke and Pets
Unless your pet is inside a poorly ventilated room and you’re smoking loads and loads of pot, they’ll probably remain sober. Yet, that doesn’t mean it’s good for them – even without a high, animals have sensitive respiratory tracts and smoke can cause irritation that leads to coughing fits and asthma.
However, there are exceptions to the above. When it comes to this issue, size does matter: a ten-pound Maltese will get high much easier than a 90-pound lab. Another factor is how the animal was exposed – sitting in a room with a dog and smoking a bowl is different than blowing that smoke directly into the dog’s face. If you do this, concentration and length of exposure come into play –
The longer the animal is exposed and the higher the dose, the more they’ll react.
An animal exposed to marijuana reacts in a variety of ways. According to Buzz Feed, they may become lethargic or have problems breathing. They may have low blood pressure or heart palpitations. They may lose their balance and control of their bowels. They may appear calm and relaxed or distressed. Symptoms of discomfort include panting, pacing, and general restlessness.
The good news is it’s difficult for animals to die from ingesting weed: they’d have to ingest a ton and smoke isn’t a likely route for that. Rather, they’d have to raid your edible collection. Even so, animals that are sick, have underlying health conditions, or are older are more likely to suffer serious or fatal cannabis consequences.
There is a record of two dogs dying from eating cannabis butter, but nothing on smoke exposure. Yet, death isn’t the only deterrent – some animals need emergency hospital care and intravenous drugs before they’re back to normal. This is traumatizing for them and you.
Medical marijuana specifically geared to help ailing pets is a different story, of course. This is engineered to help ease symptoms without the side effects (or at least with minimal side effects). Exposure to secondhand or thirdhand smoke isn’t the same thing as medicinal cannabis.
Smoking around your pet probably won’t hurt it as long as you’re in a well-ventilated room and not blowing your smoke directing in Rover or Roxy’s direction. If you’re smoking a lot, or stuff that’s very potent, it’s always smart to do it away from your furry friends. This eliminates environmental smoke altogether and then you don’t have to worry about it. If you do smoke around your pet, be watchful for symptoms and monitor any strange behavior. If your cat is suddenly the life of the party instead of sitting in the windowsill and judging Martha – because, really, why is she wearing that hat? – you might have a problem.
Studies show that people exposed to secondhand smoke can get stoned, but it takes a lot of exposure combined with little ventilation. So, what about pets?
