篇一:《关于吸烟的危害的800字作文》
关于吸烟的危害的800字作文 吸烟国历险记 一个迷蒙的夜晚，我躺在床上。忽然，从窗外闯进一个人，啊！是哈利·波特！他一把拉起我，给了我一个空气清新罩，对我说：“走，我带你去一个地方。”然后就带我骑着扫帚出发了。 我们在天空中漫游了一会儿，天已经蒙蒙亮了。我们来到一块草地上降落了，这里有许多草，有许多花，但是草不绿，花也不开，唯一长得好的就是一畦畦的烟叶。我问哈利·波特这是怎么回事？他说这是吸烟国，这里的人三岁起就开始吸烟，无论男女，坐着吸、站着吸、干活吸、闲着吸，所以，这里的空气中也充满了尼古丁。因此，草不想在这儿长，花也不想在这儿开。突然，我看见前面的一头大黄牛倒下了。我很吃惊！哈利·波特说这里的牛一个星期死一头，因为牛也无法适应这烟海的生活。我听了，催促波特快走，不然，就算我们戴了清新罩，可身上的细胞也会被尼古丁杀死的。 我们又来到一间幼儿园，我看到许多孩子在滑滑梯。我马上跑过去，可走近时，我呆住了，我发现这些小孩这个是脑瘫，那个是唇颚裂，再一个是小儿麻痹。哈利·波特说这些孩子的妈妈怀孕的时候，经常吸烟，所以导致他们畸形。我转身拉着波特就走，我满脑子是“恐怖！恐怖！”两个字。 接着，我们又去了一间医院。这里的病床上躺满了病人，男女老少都有，有的是血管堵塞、有的是肺结核、有的是肝炎„„80%都是吸烟所致。这时医生正在抢救一位女士。哈利·波特说她三岁时开始吸烟，烟龄大约有25年，烟瘾特别厉害，现在诊出肺癌。医生说，癌细胞已经扩散到她的肺部和脑部。她脸色苍白，身体虚弱，肺不时剧痛，过得生不如死。可是，在推进急救室的一刻，她还伸着手说：“烟„„烟„„”太惨不忍睹了！我掉头拉着波特就走。 我想这可真是个恐怖的旅程！我忍不住打了波特一下，说：“怎么带我来这样的鬼地方呢？”突然一痛，我扎醒了，哦，原来那是个噩梦。尽管那是个梦，可我知道烟的确是个凶残的杀手，如果不注意，它可以吞噬我们整个人类。戒烟吧！给你一个健康的身体。戒烟吧！给你一个幸福的家园。戒烟吧！给你一个美好的明天。

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！

关于吸烟危害的科技小论文
我的外公每天烟不离手，无论做什么事情嘴里都含着一根烟。可我看见他的烟盒上面印着：“吸烟有害健康！”，我就想为什么吸烟有害健康，可外公还那么爱不释手呢？于是我决定查出其中的缘由。
这个周末，我上网查了查资料：
香烟中含有尼古丁、丙酮、铝、氨/阿摩尼亚、砷、苯等20多种有害物质。其中尼古丁是香烟的主要有效成份，它能刺激人体，会令人上瘾，怪不得外公一天要抽两盒，但是我继续往下看心里很是震惊： 一支香烟所含的尼古丁可毒死一只老鼠；二十支香烟所含的尼古丁可毒死一头牛。铝可引发接触性皮炎，怪不得外公老说他的手臂爱长癣，原来这才是危害外公的罪魁祸首呀；苯是国际癌症研究会列为第一类致癌物质，它易使人激怒、睡意。。。我突然想起来了外婆老说外公是瞌睡虫，一天睡的觉比我还多，我原先以为是人老了才这样，看来都是烟在作怪呀。
医学研究曾证明吸烟者的平均寿命比不吸烟的人士短三年。而肺癌、慢性支气管炎及肺气肿会令人缠绵病榻，痛苦万分。目前全世界共有烟民11亿，估算我国有7 亿人直接或间接(被动)受到吸烟危害。据WHO(世界卫生组织)统计，每年死于吸烟有关疾病的人高达400万，平均每秒钟就有一个人死于吸烟有关疾病。
不仅是外公，许多人都有一个错误的观念，就是吸了几十年烟，就算戒了烟对身体也没有什么好处。其实无论任何年龄的人士，戒烟对于改善他们的健康都有非常大的帮助。所以为了外公的身体，为了
我们全家的幸福，我决定明天，不，马上就去对外公和所有吸烟的人说一声：请您戒烟!
篇四:《中学生抽烟危害》
远离香烟，做阳好少年
同学们，你们发现没有，最近一段时间，有些同学一下课便三三两两躲到厕所里，掏出香烟，吞云吐雾。有的同学不以为然，甚至有炫耀的心理。殊不知，你的这种行为严重损害了自身的形象，影响到了身边的同学，与《未成年人保护法》、《三中生守则》背道而驰，与三中的文明创建格格不入。今天，就此话题和大家谈谈青少年吸烟到底有哪些危害。
有数据显示，我国70 %以上的吸烟者，开始吸烟的年龄都在15-20岁之间。假设从15岁开始吸烟，每天平均吸5支香烟。按照我国公民平均寿命75岁计算。一个烟民一生将吸掉10万9千5百多支(近11万支)的香烟。五支香烟就可结束一条金鱼的生命，如果不远离香烟，你一生中吸掉的香烟将对你的身体健康产生多大的伤害。世界卫生组织曾报告说:90%的肺癌、75%的肺气肿和25%的冠心病都与吸烟或被动吸烟有关，不吸烟者平均寿命能延长10-15年。15年时间，对今天的你来说或许感觉不到它的长度，可你算算，你一生有几个十五年呢？
我们再从生理上说说。你们正处在长身体的青春期，身体各器官系统还没有发育成熟，对香烟烟雾危害的抵抗力还比较弱，容易遭受香烟烟雾的伤害。有医学研究表明：青少年吸烟成瘾可能引起思维过程的严重退化和智力功能的损伤，严重的会导致思维中断和记忆力障碍，吸烟者的联想、记忆、想象、计算、辨认力、智力效能比不吸烟者减低了10%左右，而且注意力难以集中。你们正处在接受新事物的最佳年龄，今天的努力是为了未来的美好。如果你的认知能力是因为你的抽烟而减衰，你不觉得对不住自己吗？
接下来我们从经济上算算账。你们抽烟花的钱是你们自己的吗？显然不是。因为你们现在没有真正意义上的经济实体，可以说，你们现在的绝大部分花销势必依赖你们的父母（或监护人），想一想，他们辛辛苦苦挣钱供你们读书、生活，容易吗？平时节衣缩食，一心为了你们的成长。在父母心里，你就是他们的支点。想想吧，一旦这个支点残损了，他们心中的天还不塌了？再说了，你的消费不是每天都有保障，哪天“资金链”断了，你会做出怎样的选择呢？真的不敢想啊！
劝诫规劝诫，更要靠你们自觉行动，良好的习惯起于举手投足间。同学们，远离香烟，做一个阳光好少年吧！

篇七:《小学作文：吸烟成瘾的学生(笑话)》
吸烟成瘾的学生(笑话）
五个学生吸烟成瘾。一天他们在厕所吸烟，被教导主任看见。教导主任告诉其班主任，班主任次日分别单独找他们五个谈话。 老师： “你吸烟吗？”
学生A： “吸…… ”{抽烟的危害作文}.
老师： “吸？你很光荣嘛！回家叫家长来！！” 还被暴K一通并记过。
学生A回去后和另外四个说： “老师问你们吸烟吗你们都别承认,都说不吸，这事我自己担了。”
一会儿以后。
老师： “你吸烟吗？”
学生B： “不吸。”
“那吃根薯条吧。”说着老师递过薯条。
学生B自然的伸出两个指头……
老师： “不吸？回家把家长叫来！”
老师： “吸烟吗？”
学生C： “不吸。”
“那吃根薯条吧。”
学生C小心的接过薯条，心中暗暗感激学生B。 （幸好早有预备）
老师： “不蘸点番茄酱吗？”
学生C一不留神将酱蘸多了，便开始往碗里弹…… 老师： “不吸？烟灰弹得很熟练嘛…… 把家长叫来！ 老师： “吸烟吗？”
学生D： “不…… 吸…… ”
…… 学生D吃完薯条已是汗流浃背,感觉如履薄冰。 学生D： “谢谢…… 老师…… 没事的话我先回去了。” 老师： “你不给你同学带根吃吗？”
学生D： “谢谢老师。”说着把薯条放在耳朵上…… 老师： “知道我该说什么了吧,还不去叫家长？!”
老师： “吸烟吗？”
学生E： “不吸。”
……学生E总算把薯条安心放在口袋里。
学生E转身想走，老师突然喊道： “校长来了！”
只见学生E慌忙把薯条从口袋里拿出来放到地上使劲地踩……
