Module 2　No Drugs

　　烟草吞噬着人们的生命。许多人虽然知道烟草的危害，但仍无法自拔，沉迷于吞云吐雾的快感中。了解吸烟的危害，戒烟不需要理由。

　　Hurting Yourself

　　Smoking is an addiction. Tobacco smoke contains nicotine, a drug that is addictive and can make it very hard, but not impossible, to quit.

　　More than 400，000 deaths in the US each year are from smoking­related illnesses. Smoking greatly increases your risks for lung cancer and many other cancers.

　　Hurting Others

　　Smoking harms not just the smoker, but also family members, co­workers and others who breathe the smoker's cigarette smoke, called second­hand smoke.

　　Among infants to 18 months of age, second­hand smoke is associated with as many as 300，000 cases of bronchitis and pneumonia each year.

　　Second­hand smoke from a parent's cigarette increases a child's chances for middle ear problems, causes coughing and wheezing, and worsens asthma conditions.

　　If both parents smoke, a teenager is more than twice as likely to smoke as a young person whose parents are both non­smokers. In households where only one parent smokes, young people are also more likely to start smoking.

　　Pregnant women who smoke are more likely to deliver babies whose weights are too low for the babies' good health. If all women quit smoking during pregnancy, about 4，000 new babies would not die each year.
