Smoking is the most preventable cause of premature death for people. In fact, one of five deaths of Americans can be directly attributed to tobacco smoking. Almost 90 percent of all lung cancers in American men (80 percent in women) are due to smoking, and smoking is also highly associated with cancers of the mouth, pharynx, larynx, esophagus, pancreas, uterus, cervix, kidney, and bladder. When tobacco is burned and inhaled the smoke contains thousands of chemicals with dozens of them known cancer-causing agents or carcinogens. Clearly, the best thing a smoker can do for himself or herself is to stop smoking as soon as possible.
