每年5月31日为世界无烟日。由世卫组织在1987年率先发起。目的在于提高民众对吸烟危害的重视。鼓励大众戒烟，降低抽烟带来的健康危害。每年约540万人死于烟引发疾病。在无烟日当天，世卫组织会对组织或个人进行表彰，表扬他们劝阻大众，特别是儿童戒烟所做出的努力。2008年，世卫组织呼吁全面禁止烟草广告。称广告是吸烟的最主要诱因之一。

Tobacco is a dangerous drug. It’s amazing how governments allow people to use tobacco. One reason is governments get a lot of money from taxes on cigarettes. Another reason is tobacco companies have a lot of influence on politicians. Tobacco-related health problems put a huge amount of pressure on a country’s healthcare system. Millions of working hours are lost every day because people take smoking breaks. The saddest thing is that children lose parents because of the damage tobacco did to their bodies. Tobacco contains nicotine and other poisonous chemicals. These cause many diseases, like heart problems and cancer. Smoking causes bad breath, disease, loss of energy, and it’s expensive. It’s time for the world to quit smoking.

烟草是一种高风险毒品。政府许可大众吸食烟草，这似乎匪夷所思。原因之一，政府通过高额烟草税获利，原因之二，烟草公司对政界人士产生极大影响。烟草引发疾病为各国医疗系统造成极大压力。每天，吸烟浪费了数百万工作小时。最悲哀的是，许多儿童因烟草引发疾病而失去父母。烟草包含尼古丁等其它有毒化学品。并能引发像心脏病，癌症等疾病。吸烟导致口臭、疾病、精力下降，且价格昂贵。全球戒烟行动势在必行。
