Cigarettes. Tobacco. They are dangerous, and you should not take cigarettes. You will be addicted which makes you want more, and makes most people confident. Are you even on cigarettes right now? Well, whether it is yes or no, I have some solutions.

Cigarettes come from tobacco; a plant. This plant contains nicotine; a drug which keeps you addicted. Inside a cigarette, there are more than 4000 substances added, after the tobacco itself. Some are hidden in others. Now why would they do this? These are additives. Additives are the substances that adds flavor to the cigarette. Here are some of the 4000.

Butane: Lighter Fluid

香烟，烟草，都是有害物质，大家应远离吸烟。人们一旦吸烟，就会感觉愉悦，从而逐渐对香烟上瘾，随即成为吸烟者，然后对香烟的需求量也越来越大。现在，你正在吸烟吗？不管是否，都请听我一些建议。

香烟的主要材料是烟草，烟草是一种特殊植物，它含有一种能使人成瘾的特殊成分---尼古丁。一根香烟的制作，除了烟草本身，还蕴含了4000多种其他物质，当然还有许多成分尚未鉴定出来。那为何要加入这些物质呢？人们把这些都称为添加剂，这些添加剂有助于改善香烟的味道。其中就有以下这些成分：

丁烷：一种易液化可燃性气体

甲烷：俗称"沼气".是下水道、化粪池等内产生的可燃性气体。

氨水：洗涤剂

砷：俗称"砒霜",剧毒物质。

甲醇：火箭燃料

镉：电池内的一种金属物

现在你应该有所了解，香烟中所含的很多物质都是极度危害人类身体健康的，尤其是伤肺，当你在享用香烟时，你也同时在损害自身的呼吸系统，缩短寿命，你的指甲和牙齿也逐渐呈现恶心的黄色，口臭日益加重，血压也随之升高。

这些都只是短期恶果，长期的则危害更大。

长期吸烟者，容易患肺癌，食道癌，心肌梗塞，肾癌，胰腺癌，心脏病，动脉硬化，慢性肺炎，而女性，尤其是孕妇，如果吸烟，则会危害婴儿，导致流产、畸形，或者早产、婴儿体重偏低等。
