The investigators said that now that the cohort is old enough to have had a substantial number of strokes, they have found that the smokers in the group have a significantly higher risk of stroke than do the nonsmokers.

But the forecast was not universally bad for smokers. Philip A. Wolf, MD, who presented the results at the conference, noted that the risk of stroke was dose related and reversible. The risk of stroke in light smokers (who smoked ten or fewer cigarettes per day) was not significantly higher than that in nonsmokers. However, the stroke risk of heavy smokers (those who smoked
