Does Smoking or Vaping Put Your Pet at Risk?

You already keep your pet fed, walked, and loved. But there is one hazard that many pet owners never think about: tobacco smoke, vape aerosol, and nicotine products left around the home.

It turns out your dog, cat, bird, or other companion animal can be harmed by these things, sometimes in ways you would not expect. Here is what researchers and vets have found, and what you can do about it.

What Secondhand Smoke Does to Pets

When pets breathe in smoke from a lit cigarette or from air that someone has exhaled, that is secondhand smoke exposure. Research has linked it to respiratory irritation and a higher risk of certain cancers in dogs and cats compared to pets in smoke-free homes.

Dogs with longer noses, such as retrievers and collies, may face a higher risk of nasal cancer in particular. That is because carcinogens can collect in those long nasal passages, according to research from the University of Kentucky.

But smoke does not just disappear when the cigarette is out. The chemical residue left behind on surfaces, fabrics, furniture, bedding, and even your pet’s fur is called thirdhand smoke. It lingers long after the air has cleared.

Cats are especially vulnerable here. Because they groom themselves so often, they can lick tobacco residue right off their own fur. Dogs are at risk too; they chew and lick blankets, pillows, toys, and furniture where that residue settles.

The American Lung Association notes that secondhand smoke exposure in pets is linked to respiratory disease, heart disease, and certain cancers.

The Hidden Danger of Nicotine Products Left Within Reach

Pets explore the world through smell and taste. That means a cigarette butt on the patio, a nicotine patch on the nightstand, or a vape pod left on the coffee table can look like something worth investigating.

If your pet swallows nicotine, it can cause rapid and dangerous poisoning. If you suspect your pet has ingested any nicotine product, the Pet Poison Helpline can be reached at 855-764-7661. You can also contact your veterinarian immediately.

What About Vaping?

Vaping indoors is not a safe alternative for your pet. A study found that e-cigarette aerosol can be dangerous for pets if inhaled. According to the Pet Poison Helpline, vape aerosol can irritate an animal’s airway, causing wheezing, coughing, and trouble breathing.

Vape aerosol can also contain toxic metals and carcinogenic molecules, along with added flavors. Those sweet and fruity scents that make vapes appealing to people can attract pets, too. A pet that chews on a vape device, cartridge, or pod faces risks from nicotine poisoning as well as injury from batteries, plastic, or glass parts.

Vaping outdoors, away from doors and windows, is the safer choice when pets are in the home.

Birds, Small Mammals, Reptiles, and Amphibians Face Extra Risks

If you have a bird, rabbit, hamster, reptile, or amphibian, take extra care. These animals can be especially sensitive to smoke, aerosol, and airborne toxins.

Birds are particularly at risk. According to Britannica, their respiratory systems move air through the body more efficiently than mammals do. That means airborne irritants can affect them quickly, even at low exposure levels. Keep birds away from any smoking or vaping area, and call a vet quickly if you notice breathing changes or unusual behavior.

Reptiles and amphibians face a different challenge. Their tanks and terrariums often have limited airflow, so irritants can linger and settle on bedding, water dishes, and surfaces. Amphibians may be especially vulnerable because their skin can absorb substances from the environment.
