Cigarette smoking is a major cause of disease number of countries. More than 400,000 deaths occur each year as a result of cigarette smoking. In addition, exposure to second-hand smoke is estimated to cause 40,000 deaths each year from heart disease and contributes to other diseases as well. Smoking is a major cause of non-fatal diseases including osteoporosis, skin wrinkling, Cigarette smoking ise, impotence, and pregnancy complications. Quitting and staying away from cigarettes is difficult, but not impossible. Smoking cessation has major and immediate health benefits for men and women of all ages. The earlier you quit, the greater the benefits. People who quit smoking before age 50 reduce their risk of dying over the next 15 years by one-half, as compared to those who continue to smoke. Smoking cessation is also important to those who do not smoke since being exposed to second-hand cigarette smoke is responsible for a number of serious health conditions. Cigarette smoking doubles the risk of developing coronary heart disease, and smoking cessation can rapidly reduce this risk. One year after stopping smoking, the risk of dying from coronary heart disease is reduced by about one-half and continues to decline over time. In some studies, the risk of heart attack was reduced to the rate of nonsmokers within two years of quitting smoking. Smoking increases the risk of long-term lung diseases such as chronic obstructive pulmonary disease. While much of the lung damage caused by smoking is not reversible, stopping smoking can reduce further damage to the lungs, and many smokers with a chronic cough and sputum (phlegm coughed up from the lungs) note an improvement in these symptoms during the first year after stopping smoking.
