Passive Smoke
When someone smokes, those around him or her smoke too. Similarly, a pregnant woman, who is smoking, is actually subjecting her fetus to the harmful effects of smoking and it is not difficult to understand that smoke from cigarettes, which is so dreadful for the smoker, is also damaging to others. Passive smoking is a serious public health risk for both children and adults. It is also a major source of indoor air pollution. It was estimated that prolonged passive smoking increases the risk of lung cancer by approximately 20 to 25 per cent. Smoking during pregnancy increases risk of Sudden Infant Death Syndrome (SIDS) and passive smoking is known to be one of the main contributing factors in the development of childhood asthma. Female fertility can suffer because of passive smoking, making it harder to conceive a child.
