Here are some facts from the American Cancer Association:
87% of lung cancer
deaths can be attributed to tobacco use. (Source: Cancer Facts and Figures 2007)
In the United States, tobacco use is responsible for nearly 1 in 5 deaths or an estimated 440,000 deaths per year during 1995-1999.
Each year, about 3,000 nonsmoking adults die of lung cancer as a result of breathing secondhand smoke
and causes an estimated 35,000 deaths from heart disease
in people who are not current smokers.
