吸烟有害健康作文
们每个人的理想。“吸烟有害健康”在这个世纪流传广泛，大家都知道吸烟对我们的健康有着极大的伤害。我想，同学们的爸爸大多有吸烟这个坏习惯吧。同学们可能都想脱离这个云雾缭绕的环境吧，可我们不但没有脱离，也许还会越陷越深哪！所以，同学们都应该奉劝亲人，远离危害！
我们也常听人说“饭后一支烟，快乐像神仙”，可事实并非如此。吸烟的坏处就像繁星点点，数也数不完，何况很多人都爱抽烟呢。烟草里有三种危险化学物质：焦油，尼古丁和一氧化碳。焦油是由好几种物质混合成的物质，在肺中会浓缩成一种粘性物质；尼古丁是一种会使人成瘾的药物，由肺部吸收，主要是对神经系统发生作用；一氧化碳能减低红血球将氧输送到全身去的能力。其实烟也是一种毒品，只是没有那么剧烈，国家没有禁止而已。敬爱的叔叔阿姨们，你们在抽烟时想过后果么？吸烟不仅对自己的身体造成威胁，还对你身边那些被动吸烟的人也造成了极大的危害。这一根根烟头，就像一只只毒药，徐徐的向我们逼近，给我们的生活和工作也带来了极大的威胁。假如你每天都处在烟雾中，你的身体会越来越虚弱，病魔会时时侵害你，甚至危及你的生命。可怕的是：一个每天吸15到20支香烟的人，极易患肺癌、口腔癌或喉癌致死的机率，要比不吸烟的人大14倍；极易患食道癌致死的机率比不吸烟的人大4倍；比死于膀胱癌的机率要大两倍；死于心脏病的机率也要大两倍。吸香烟是导致慢性支气管炎和肺气肿的主要原因，而慢性肺部疾病本身，也增加了得肺炎及心脏病的危险，并且吸烟也增加了高血压的危险。听了这一句句惊心动魄的描述，你感觉到危险正向你慢慢的逼近了吗？你体会到自己那饱受痛苦的呻吟了么？想一想，吸烟除了带来危害，它能给予你什么？给予你家人为了你抽烟而闹得家庭不和么？所以奉劝那些有烟瘾的朋友们好好的想一想吸烟的危害，及时戒烟吧！
为了防止越来越多的人吸烟，仅仅靠一个人的力量是不够的，我们大家应该团结起来，去掉这一大不良习惯和危害。
现在，我郑重的呼吁大家，放下手中的烟吧！让我们一起和家人幸福的生活，一起创造美好的未来吧！

吸烟的危害
作者：高二八班 林文龙 吸烟，是现如今危害青少年健康的最大隐患。吸烟的危害很多，但它不但吞噬吸烟者的健康和生命，还会污染空气危害他人。
香烟燃烧时释放38种有毒化学物质，其中烟雾中的焦油沉淀在肺部绒毛上，使支气管发生慢性病变。气管炎，肺气肿，心脏病便会发生。
就在我们身边，也不难看见一些吸烟的同学，他们自以为抽烟能让自己变得“潇洒”，其实香烟正危害着他们的健康和生命，也会给周围的人都带来了“毒气室”般的环境。 二手烟是指吸烟者将烟吸入肺部之后，再吐出来的烟雾，让他人吸入肺中。这种吸二手烟的方式，对被动吸烟者的身体造成了很大的危害，这种危害远远大于吸烟者本身受到的伤害。所以，我呼吁那些吸烟的同学，为了您和家人的健康，请尽早戒烟。在我们身边也有许多推销香烟的企业。的确。中国是烟草大国，大部分的税收也是来源于烟草税收。但是，我们也能在香烟盒上看到这样的标语：为了您的健康，请尽早戒烟。所以，尽管国家没有对烟草业进行强制的控制，但也无时无刻的提醒我们的烟民尽早戒烟。
打开电视机，我们也能看到许多关于禁烟的广告，例如：抽烟不避人，德行如烟散。这些禁烟广告，它们时刻提醒这{作文吸烟的危害}.{作文吸烟的危害}.
人们，香烟对人们的伤害是很大的。在公共场所，我们也不难看到一些关于禁烟的标语，这些标语时刻提醒着人们不要因为自己的一时之快，而危害他人的健康。所以，我们希望抽烟的同学们，尽早改掉吸烟这个坏毛病。不仅为了你自己，也为了身边那些爱你的人和你爱的人。

篇五:《吸烟的危害》{作文吸烟的危害}.
吸烟的危害
1.吸烟的危害性大家众所周知，而对于青少年来讲吸烟还会印象青少年身体成长发育和心理发育。一些研究者在美国25个洲做过一个调查：以不吸烟者的死亡率为1.00计算，15岁以下吸烟者死亡率为19:.68;20~25岁死亡率为10.08;25岁以上的死亡率为4.08。这些数据说明越早吸烟的人患上肺癌的发生率也就越高。下面我们来看看吸烟具体能给青少年所造成的危害，并警惕正在吸烟的人为了自己的健康趁早戒烟。
2.危害呼吸系统
青少年的支气管从解剖学看，比较直观，烟雾微粒和有害物质容易达到细支气管和肺泡，因而毒物易吸收，组织损伤严重。吸烟时间长，就会造成慢性支气管炎，肺气肿，甚至肺心病而缩短寿命
3.影响体能
某市对一所中学学生进行了身高，体重，胸围，肺活量多项体格调查发现吸烟者生长发育差。肺部和心脏的发育也受到影响，直接影响体育锻炼的耐力和效果.吸烟还会引起少女的月经紊乱和痛经。
4.影响智能
烟雾中的一氧化碳吸入肺内，与血红蛋白结合，剥夺了血红蛋白与氧的结合，降低了血液的含氧量，影响了大脑氧的供应，长此下去损害脑细胞，使记忆力减退，反而不灵敏。有专家对青少年学进行实验，结果表明，吸烟者的智力效能比不吸烟者降低了10.6% 。
5.影响品德
青少年吸烟的新特点是：集体成伙吸烟越来越多，卷烟消费档次越来越高，女青年吸烟者日益增多。而且青少年由吸烟开始走上吸毒。多数吸烟学生纪律松弛，学习成绩差，个别学生为了找钱买烟，打架斗殴，走上犯罪道路。
6.加重经济负担
烟需要花钱去买，而青少年又无独立经济来源，同时在人际交往中吸烟易交上坏朋友，因此，中学生吸烟容易成为走向违法犯罪道路的诱发因素。
