Pets can be harmed by second-hand smoke and/or ingestion of tobacco products..

May 11, 2010 - Amid growing evidence that secondhand smoke (shs, involuntary, environment tobacco, ets, sidestream) is causing cancers and possibly a range of other health problems in pets, many groups are intensifying efforts to encourage people to stop smoking — if not for their own sake, then for their animals'.

The danger of poisoning your pet is increased with all tobacco products including moist snuff tobacco (MST) products like Copenhagen or Camel SNUS and now the dissolvable tobacco products like Camel Orbs, Sticks or Strips. (Poison Control Centers - Camel Dissolvables - Nicotine Toxicity..) A lethal dose of nicotine in dogs can be about 20 to 100 mg. Cigarettes tally 10 to 30 mg of the chemical, and cigars can contain 15 to 40 mg.

April is Prevention of Cruelty to Animals Month..

Veterinarians are redoubling efforts to warn smokers of the dangers to their pets, and smoking-cessation programs, including Utah Tobacco Prevention and Control, Breathe New Hampshire and, have posted fact sheets or printable fliers on their websites. Some groups are sharing information where animal aficionados gather, including at last month's Dachshund Dash in Oklahoma City, where the Oklahoma County Tobacco Use Prevention Coalition warned of secondhand smoke's dangers to dogs.

And the ASPCA last month linked up with American Legacy Foundation, a stop-smoking group, to spread the word to the pet lovers of the world.

Studies have shown that toxins in secondhand smoke can cause lung and nasal cancer in dogs and malignant lymphoma in cats. "The evidence is striking," says Steven Hansen of the ASPCA's Animal Poison Control Center. "Most veterinarians believe pretty strongly secondhand smoke presents a strong danger to dogs and cats with pre-existing respiratory problems," he says. "And extrapolating, why would you expose a healthy animal?"

Although studies showing strong links between smoking and pets are limited to a few cancers, veterinary oncologist Aarti Sabhlok, who treats 40 or more cancer patients a week at San Francisco Veterinary Specialists, believes an "animal in an environment with constant exposure to a toxin, and that would include cigarette smoke, could be at greater risk of developing tumors."

It may seem odd to believe that people who continue to smoke despite the risks to themselves and others might pay heed when pets' health is jeopardized, "but we know people sometimes pay more attention to their pets' well-being," Hansen says.

Indeed, a Web-based survey of 3,293 adult pet owners published last year found that 48% were smokers or living with smokers, and 37% said clear evidence that smoking is harmful to their pets would motivate them to quit or ask the people they live with to quit; 14% said such evidence could prompt them to do all their smoking outside.
