Early Smoking Shortens Life

Even though the significant negative health effects of cigarette smoking are well known, smoking rates in young people continue to rise. Analysis of data from the Harvard University Alumni Study found that men who reported smoking at age 18 experienced a 30% increase in all-cause mortality (P<0.001). Deaths from smoking-related cancers increased by 91% in these same men (P<0.001). Quitting smoking lowered risks significantly over those who continued.
