California State has declared passive smoking as toxic as researchers have found linkage between passive smoking and increased incidence of cancers and lung diseases due to passive smoking. California state is taking tough measures against tobacco smoking as it as already banned smoking in public places and work place.
The decision to make such a declaration came after many scientific studies had linked passive smoking to a range of cancers and respiratory diseases, according to California Air Resources Board. A study report released last September found a sharply increased risk of breast cancer in young women exposed to tobacco smoke. It also linked second-hand smoke to premature births, asthma and numerous health problems in children.
The study found that about 16 percent of all Californians smoked, but that 56 percent of adults and 64 percent of adolescents were exposed to second-hand smoke.
According to WHO, smoking is a greater cause of death and disability than any single disease considered responsible for approximately five million deaths worldwide every year. It is believed there are 1.1 billion smokers in the world - 800 million of them in developing countries.
