Not only are smokers twice as likely to have strokes, they are almost a decade younger than non-smokers when they have them, according to a study presented October 3 at the Canadian Stroke Congress. Between January 2009 and March 2011, researchers studied 982 stroke patients (264 smokers and 718 non-smokers) at an Ottawa prevention clinic. They found the average age of stroke patients who smoked was 58, compared to age 67 for non-smokers.
