Smoking and Stroke

Your risk of stroke may hinge more on how much you smoked in the past than how long ago you quit, according to a small study reported today at the American Stroke Association's International Stroke Conference 2006.

Previous studies have indicated that five to 15 years after quitting, former smokers' excess stroke risk declined to the same level as that of people who have never smoked.
