The excess risk of death increases with the number of years of smoking and the number of cigarettes per day.
Smoking becomes more hazardous with increasing age.
U.S. women account for only 20% of the women in the developed world, but in 1990, they made up 40% of all deaths attributed to smoking among women in developed countries.
The risk of death has increased significantly between the 1950s and 1980s. Adolescent women who are smoking more and starting earlier will experience higher death rates than those who don't.
