Doctors believe that second-hand smoke may cause lung cancer in people who do not smoke. Nonsmokers often breathe in the smoke from other people's cigarettes. This is second-hand smoke. The U. S. Environmental Protection Agency (美国环保局) reports that about fifty-three thousand people die in the United States each year as a result of exposure (暴露) to second-hand smoke.
It is harder for children to avoid second-hand smoke. In the United States, nine million children under the age of five live in homes with at least one smoker. Research shows that these children are sick more often than children who live in homes where no one smokes. The damaging effects of second-hand smoke on children also continue as they grow up. The children of smokers are more than twice as likely to develop lung cancer when they are adults as children of nonsmokers. The risk is even higher for children who live in homes where both parents smoke.
