    Thirdhand smoke another danger

Most people realize that secondhand smoke is harmful, especially to children and those with chronic health problems such as heart disease and lung disease. This has led to smoking bans and clean indoor air policies. Research is now beginning to show another concern.

"Thirdhand smoke" is the term given to the residual of tobacco smoke contamination that settles into the environment and stays there even after a cigarette has been extinguished. The chemical particles resulting from the burning of tobacco, including tar and nicotine, linger on clothes, hair, upholstery, drapes etc., long after the smoke has cleared from the air.

These particles are formed from more than 200 poisonous gases, many of which are cancer causing, such as cyanide, ammonia, arsenic, and polonium-210 (which is radioactive.) These chemicals are deposited on surface areas and over time can be released back into the air.

New research has found that the residuals of tobacco smoke stay in the lungs after a smoker takes the last puff of a cigarette. It can take up to 2-3 minutes before they stop exhaling the toxic products of combustion. This expelled air may also contribute to secondhand tobacco smoke and to the residual of tobacco particles that can settle in places considered smoke-free.

Most people are aware of the negative effects of visible smoke and make efforts to control the amount that non-smokers are exposed to. We are now learning that tobacco toxins can remain in the environment as thirdhand smoke long after the smoking period is over. Children seem to be at greatest risk of being affected as they inhale these particles from clothes, rugs, draperies etc.

Making the home and car totally smoke-free is the best way to protect those you love. Also, waiting 2-3 minutes after finishing a cigarette to have contact with children or return to smoke-free areas is likely to be beneficial.

In my counseling experience, I've had people ask me whether they need to clean their house or car after quitting smoking. The answer is a very strong "Yes!" Once you make the commitment to becoming smoke-free, have your car detailed and give your house a good, thorough cleaning to get rid of thirdhand smoke. By doing so, you not only protect yourself and your loved ones from the harmful remnants of your former tobacco-controlled life, but you also deepen your resolve to remain a non-smoker for good.
