Cigarette smoking is the single most deadly personal behavior in human history and remains a potent population health threat. Today in the United States, one in five deaths can be attributed to cigarette smoking. Recent models suggest that even if we were to magically cease cigarette smoking today, some 200 000 life-years will be lost in coming years because of past cigarette smoking.
