U.S. Surgeon General Richard H. Carmona today released a new comprehensive report on smoking and health, revealing for the first time that smoking causes diseases in nearly every organ of the body. Published 40 years after the surgeon general's first report on smoking -- which concluded that smoking was a definite cause of three serious diseases -- this newest report finds that cigarette smoking is conclusively linked to diseases such as leukemia, cataracts, pneumonia and cancers of the cervix, kidney, pancreas and stomach.
