Abstract

Cigarette smoke is a complex mixture of 4,000 chemical compounds, including 43 known carcinogens. It is well known that smoke acts as the initiator and promoter in the process of carcinogenesis, and the risk of cancer is directly proportional to the amount and duration of smoking. Tobacco is the cause of30% ofall cancer deaths and one of the major risk factors for coronary heart disease, along with high bloodpressure and hyperlipidemia. Cigarette smoking is estimated to be responsible for more than 20% of aU coronary heart disease deaths in men over 86 years of age and for approximately 45% of such deaths in men aged less than 65 years. About 80% of mortality from chronic obstructive lung disease is attributable to cigarette smoking, and the age — adjusted death rate for COPD is 10 — times higher in current smokers than in nonsmokers. Peptic ulcer disease, osteoporosis, skin wrinkling, and retarded fetal growth are all associated with cigarette smoking. Through passive smoking, 69% of individuals develop eye irritation, 29% have nasal symptoms, 32% have headaches and 25% develop acough. The infant admission rate increases with mother's smoking amount, and the relative risk of lung canceris 1.8 in smoker's spouse. Tobacco is the single, chief, avoidable cause of death in our society, and the most important public issue of our time.
