Then they considered COPD estimates and concluded that U.S. Adults had a mixed 14 million smoking-related ailments in 2009 2009. ‘The implication is definitely that smoking causes more harm than we previously thought, a lot of it in chronic pulmonary obstructive disease,’ stated Dr. Steven Schroeder, a professor of medication at University of California, San head and Francisco of its Smoking cigarettes Cessation Leadership Center. ‘When you see how smoking hurts you, people usually first consider deaths, and those who are sick then. There is a lot more lifetime illness linked to smoking.’ Schroeder said he was amazed that researchers found even though women have a lower overall rate of smoking than guys, they have an increased rate of COPD.
