AHA Scientific Position found cigarette smoking by children and teenagers in theUnited Statesis a major public health problem.

If not controlled,later in life it will become a major risk factor for coronary heart disease (冠心病) ，which leads to heart attack. Among young men and women— who are otherwise at very low risk of developing coronary heart disease—cigarette smoking may cause as many as 75 per cent of the cases of coronary heart disease. The longer a person smokes,the higher the risk of coronary heart disease. More than 80，000 people die each year from coronary heart disease caused by smoking.

Most adult smokers started when they were teenagers;smoking habits in youth seem to determine lifetime cigarette consumption (消费) .丁here’s also evidence that those who begin smoking before they’re 20 have the highest incidence and earliest onset of coronary heart disease and high blood pressure.

What about passive (被动的) or second-hand smoking? About 59 per cent of American children aged between 4 and 11 are suffering from second-hand smoke at home. Studies have shown that children (especially infants) of parents who smoke have more lung illnesses,such as bronchitis(支气管炎) and pneumonia,and can develop asthma(哮喘) . And because smoking parents are more likely to cough and spread germs,their children are more likely to develop chest illnesses. Exposure to tobacco smoke also increases the risk of heart disease.
