A study ties a host of new diseases to smoking, and says an additional 60,000 to 120,000 deaths each year in the United States are probably due to tobacco use. The study by the American Cancer Society and several universities is published in the Thursday, Feb 12, 2015 edition of the New England Journal of Medicine. It looks beyond lung cancer, heart disease and other conditions already tied to smoking and adds breast cancer, prostate cancer and even routine infections to the list. (AP Photo/Matt Rourke)
