Question: what are the good and bad effects of smoking?
Answer: Smoking causes about 90% (or 9 out of 10) of all lung cancer deaths. More women die from lung cancer each year than from breast cancer. Smoking causes about 80% (or 8 out of 10) of all deaths from chronic obstructive pulmonary disease (COPD). Cigarette smoking increases risk for death from all causes in men and women.
