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

    Methane: Sewer Gas

    Ammonia: Household Cleaner

    香煙，煙草，都是有害物質(zhì)，大家應(yīng)遠(yuǎn)離吸煙。人們一旦吸煙，就會(huì)感覺愉悅，從而逐漸對(duì)香煙上癮，隨即成為吸煙者，然后對(duì)香煙的需求量也越來(lái)越大�，F(xiàn)在，你正在吸煙嗎？不管是否，都請(qǐng)聽我一些建議。

    香煙的主要材料是煙草，煙草是一種特殊植物，它含有一種能使人成癮的特殊成分---尼古丁。一根香煙的制作，除了煙草本身，還蘊(yùn)含了4000多種其他物質(zhì)，當(dāng)然還有許多成分尚未鑒定出來(lái)。那為何要加入這些物質(zhì)呢？人們把這些都稱為添加劑，這些添加劑有助于改善香煙的味道。其中就有以下這些成分：

    丁烷：一種易液化可燃性氣體

    甲烷：俗稱"沼氣".是下水道、化糞池等內(nèi)產(chǎn)生的可燃性氣體。

    氨水：洗滌劑

    砷：俗稱"砒霜",劇毒物質(zhì)。

    甲醇：火箭燃料

    鎘：電池內(nèi)的一種金屬物

    現(xiàn)在你應(yīng)該有所了解，香煙中所含的很多物質(zhì)都是極度危害人類身體健康的，尤其是傷肺，當(dāng)你在享用香煙時(shí)，你也同時(shí)在損害自身的呼吸系統(tǒng)，縮短壽命，你的指甲和牙齒也逐漸呈現(xiàn)惡心的黃色，口臭日益加重，血壓也隨之升高。

    這些都只是短期惡果，長(zhǎng)期的則危害更大。

    長(zhǎng)期吸煙者，容易患肺癌，食道癌，心肌梗塞，腎癌，胰腺癌，心臟病，動(dòng)脈硬化，慢性肺炎，而女性，尤其是孕婦，如果吸煙，則會(huì)危害嬰兒，導(dǎo)致流產(chǎn)、畸形，或者早產(chǎn)、嬰兒體重偏低等。
