Smoking is the most significant and potent risk factor for coronary heart disease.
In fact, if you smoke, your risk of dying from a heart attack is at least 2-4 times that of a person who has never smoked. But the good news is that the risk of a heart attack drops by almost a third after the first year of quitting smoking and reaches the level of persons who have never smoked by the third or fourth year. Since 1986, lung cancer has exceeded breast cancer as the most common cause of cancer death among women. It has been the leading cause of cancer deaths in men for decades. Chronic lung disease, or emphysema as it is commonly called, is the fourth leading cause of death in the United States accounting for more than 100,000 deaths each year and the death rate from emphysema has more than tripled since 1970.
