Most everyone knows smoking is bad news, but secondhand smoke gets less hype although it causes just as sobering health problems for non-smokers, especially for young people. Yet every day, millions of children inhale smoker's air.

Studies suggest that exposing fetuses, infants, and small children to smoke, whether indoors or outside, can cause damaging, life-long effects. Because their developing bodies and higher breathing rates make them more vulnerable to smoke, exposed children suffer more cases of asthma, respiratory infections like bronchitis and pneumonia, and lung cancer.

Energy efficiency at home and at work comes with a price-stale air. One of the key ways to keep heating and air conditioning costs down is to trap air indoors. However, by sealing windows shut and preventing ventilation, air in buildings can become as polluted as the pea soup skies of the largest cities. Breathing bad indoor air can lead to immediate health problems like irritated eyes and asthma, or long-term diseases as serious as heart disease and cancer.
