You know smoking is bad, but second hand smoking is even worse as there is no idea how much smoke you actually can inhale. The worst effected in this are small children between the age of 3 and 11, a recent research shows.

The study conducted by Center for Disease Control and Prevention (CDC) released this month shows that there is more evidence that smoking is harmful to children who tend to inhale a lot of smoke when around smokers. This early exposure to tobacco fumes can lead to many breathing and heart related diseases. 54 percent if the children tested showed high levels of toxicity which is sign of tobacco exposure. This sort of exposure leaves the small children vulnerable to diseases like bronchitis, pneumonia and asthma. Sever exposure can damage the functioning capabilities of the lungs.

The CDC report also shows that despite programs to create awareness amongst parents of small children, the maximum exposure to second hand smoke still happens at home as very few family members take heed when smoking.
