Default Re: Bann On Public Smoking

From The American Cancer Society
The US Environmental Protection Agency (EPA) has classified secondhand smoke as a Group A carcinogen, which means that there is sufficient evidence that it causes cancer in humans. Environmental tobacco smoke has also been classified as a "known human carcinogen" by the US National Toxicology Program.
Secondhand tobacco smoke contains over 4,000 chemical compounds. More than 60 of these are known or suspected to cause cancer.
Secondhand smoke can be harmful in many ways. In the United States alone, each year it is responsible for:
  • An estimated 35,000 to 40,000 deaths from heart disease in people who are not current smokers
  • About 3,000 lung cancer deaths in nonsmoking adults
  • Other respiratory problems in nonsmokers, including coughing, phlegm, chest discomfort, and reduced lung function
  • 150,000 to 300,000 lower respiratory tract infections (such as pneumonia and bronchitis) in children younger than 18 months of age, which result in 7,500 to 15,000 hospitalizations
  • Increases in the number and severity of asthma attacks in about 200,000 to 1 million asthmatic children
The 1986 US Surgeon General's report on the health consequences of involuntary smoking reached 3 important conclusions about secondhand smoke:
  • Involuntary smoking causes disease, including lung cancer, in healthy nonsmokers.
  • When compared with the children of nonsmoking parents, children of parents who smoke have more frequent respiratory infections, more respiratory symptoms, and slower development of lung function as the lung matures.
  • Separating smokers and nonsmokers within the same air space may reduce, but does not eliminate, the exposure of nonsmokers to secondhand smoke.
