According to the World Health Organisation, there are almost 6 million deaths a year caused by tobacco use, and 600,000 of those are the result of non-smokers being exposed to second-hand smoke. In Australia, smoking is the leading risk factor for preventable cancer and according to the Cancer Council, 1 in 5 cancer deaths can be attributed to smoking.
Smoking affects our pets, as well
The Society for Prevention of Cruelty to Animals (SPCA) is calling for pet owners to learn about, and act to reduce, the health impacts of second-hand smoke on animals.
It has been proven that second-hand smoke increases health risks to pets and has been associated with cancers and respiratory infections, similar to the effect on humans. Studies have shown that exposure to tobacco and second-hand smoke has been associated with certain cancers in dogs and cats, allergies in dogs, as well as eye, skin and respiratory diseases in a range of other animals. Even fish can be affected by our smoking habits as the pollutants from smoke are absorbed into their water and can kill the fish.
“The best thing you can do to protect your family and pets from second-hand smoke is to stop smoking altogether. If you’re still working through the process of quitting, don’t smoke around your pets, inside or outside. Keep both your home and car smoke free to reduce the risk of cancers and serious smoke-related health problems for your family and pets,” says SPCA Auckland’s Chief Scientific Officer Dr Arnja Dale.
Effects of second-hand smoke on cats
As cats lick themselves when grooming, they ingest dangerous carcinogens from smoke that are absorbed by their fur, sometimes leading to oral cancer and lymphoma.
Cats in households with second hand smoke exposure are almost 2.5 times more likely to develop malignant lymphoma as cats with no exposure. The risk increases to 3.2 times more likely in cats exposed for five or more years.
Effects of second-hand smoke on dogs
Dogs exposed to second hand-smoke are more likely to suffer from a range of diseases, including nasal cancer, lung cancer, asthma and bronchitis, than non-exposed dogs.
The shape of a dog’s head plays a role in the types of cancer most likely to develop. Long-muzzled dogs, such as collies, are 250 per cent more likely to develop nasal cancer, since their nasal passages have more surface area on which toxins can accumulate. Breeds with short muzzles are more likely to develop lung cancer and other respiratory diseases.
Cost of caring for your pets
Veterinary expenses can be a significant drain on the budget. In Australia, for example, it is estimated that $1.7 billion dollars is spent on veterinary treatments each year.
The cost of cigarettes is steep enough, but if you need some extra incentive to quit, maybe factor in the cost of potential related illnesses in your pets, as well.
