Nicotine may accelerate atherosclerosis, may be as dangerous as tar
Date:9/13/2007

osclerosis, in part, by blocking production of nitric oxide, a chemical that mediates the protective functions of the lining of blood vessels.

"These findings are preliminary. Going forward we will want to look at whether doping cigarettes with extra nicotine increases their atherogenic potential; whether blockers of nicotine reduce atherosclerosis; and if oral administration of nicotine has the same effects," says Dr. Catanzaro.

About 20 percent of Americans smoke. Cigarette smoke is linked to risk for cancer, chronic lung disease (emphysema and chronic bronchitis), cardiovascular disease (atherosclerosis, thrombosis and vascular dysfunction), stroke and cataracts as well as poor wound healing.
