    吸煙對人們有健康有害。吸煙不但污染空氣，給他人帶來痛苦，譬如給孩子及不吸煙者帶來痛苦，而且還引起支氣管炎、肺癌、胸癌和喉癌。
    吸煙與癌有關。煙是一種混合物，其中有氣體蒸發的化學物質、微細的煙塵顆粒和一些固態物質。煙里有焦油和尼古丁，這兩種東西毒性很大。煙吸人肺里，所有這些成分沉積在肺部的粘膜上。集中的一點就在支氣管分叉處。大多數癌癥就是由此處開始的。
    世界各國政府應發起一場禁煙運動。首先，應采取立法措施。第二，嚴格限制刊登香煙廣告。第三，禁止在某些公眾場所吸煙，譬如，不許在劇場、影院、候機廳和候車吸煙。這樣，我們就會使那些吸煙者對他們的壞習慣逐漸感到不舒服。最后一點是，應提高香煙價格。
