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.

For the nonsmokers of the world there is nothing more frustrating than being immersed in a cloud of somebody else's smoke. While states like New York and New Jersey have enacted no-smoking laws, they don't affect the smokers puffing away at that house party, or while waiting for the bus, or at the beach. Yuck.

While they're not as effective as say, sitting inside of a big, plastic bubble, the daily intake of certain supplements can help protect you from second-hand smoke.
