吸烟的危害演讲稿篇1

good afternoon, everyone!

iam very glad to have a speech here. my name is xxx, and my major is chemistry. hu bei, jing zhou is my hometown, a famous city in the three kingdoms, and it is rich in rice and fish. i graduated from xxx university, and now, i am studying in xxx university. in my spare time, i often play computer games, surf on line, or travel with friends and sometimes i like being alone and doing nothing.

my topic is smoking, do you smoke? yes or no? it has been estimated that smokers have made up half of the population. and the smokers are being younger and younger, even including some middle school students, both boys and girls. nowadays, more and more people have realized that smoking can do harm to their health. however, some people still enjoy smoking. why? some of them think it is very cool that they can smoke like a famous handsome actor; some people think that they will be looked more mature when smoking. the brain workers think that smoking can bring them inspiration and the sad people may relieve themselves by smoking. is the smoking really so effectively? if smoking was as good as what they say, our life would be easier just though smoking.

in fact, smoking is a bad habit and it can cause a lot of diseases, such as tracheitis(气管炎), lung cancer and many other diseases. recent years, there are tens of thousands of people dying of smoking. meanwhile, smoking is a waste of money. besides, careless smokers may cause dangerous fires. smoking is bad for not only the smokers themselves, but also non-smokers. second hand smoking has been recognized harmful to other people. even worse, it may cause more damages for children and pregnant women.

if you are a smoker, here are some tips can help you to reduce the harm from smoking: first, you can use a filter which can prevent most of the poisonous substance breathing into your lung, such as nicotine and tar(焦油). second, drink a cup of tea when you are smoking, because tea is able to detoxify. third, you can smoke the electronic cigarette rather than cigarette. though the electronic cigarette is not completely safety, it is less harmful for health compared with cigarette. i think the most effective way to reduce the harm is that smoke as less as you can. the less you smoke, the more health you will get, and then you will live longer.

at last, considering the health of yourself and other people who you care and you care, please do not smoke!

高中里有很多学生吸烟，原因可能是他们觉得手中有一支烟看上去很酷或者显得更成熟。但是，不吸烟的原因有很多。吸烟有害我们的健康，对我们的心脏和肺很危险。很多疾病都是由香烟引起的，而且烟的味道不好闻。

二手烟对周围的人也很危险。因此，公共场所禁止吸烟是很多国家的一项严厉规定。最重要的是，一旦你上瘾了就很难戒掉了。所以，为了每个人的健康，我们必须远离香烟。

吸烟的危害演讲稿篇3

尊敬的各位老师、亲爱的同学们：

早上好!

“吸烟有害健康”在这个话题一直被人们关注着，大家都知道吸烟对我们的健康有着极大的伤害。近50多年来，世界各国特别是工业发达国家，肺癌的发病率和病死率均迅速上升，死于癌病的男性病人中肺癌已居首位。大量流行病学研究证实，吸烟是导致肺癌的首要危险因素。为了引起国际社会对烟草危害人类健康的重视，世界卫生组织建议将每年的5月31日定为世界无烟日。

香烟中的尼古丁、一氧化碳和多种其它金属化合物对人体危害很大，对青少年的影响更甚。据医学研究表明，青少年正处在生长发育时期，各生理系统、器官都尚未成熟，其对外界环境的有害因素的抵抗力比成人弱，易于吸收毒物。据调查，吸烟开始年龄与肺癌死亡率直接相关。15岁以下开始吸烟者死亡率为19.68%;20～24岁为10.08%;25岁以上为4.08%。这说明吸烟开始年龄越早，肺癌发生率与死亡率越高。同时，吸烟还会损害大脑，使思维变得迟钝，记忆力减退，影响学习和工作，使学生的学习成绩下降。心理研究结果表明，吸烟者的智力效能比不吸烟者低了10.6%。

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。烟草里有三种危险化学物质：焦油，尼古丁和一氧化碳。20__年世界无烟日演讲稿优秀3篇20__年世界无烟日演讲稿优秀3篇。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。

吸烟不仅会对自己的身体造成威胁，还会对你身边那些被动吸烟的人也造成极大的危害。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。

现在，我郑重的呼吁大家，积极宣传吸烟有害健康的科学知识，让你的亲人、朋友放下手中的烟，形成禁烟的良好氛围，把禁烟纳入精神文明建设的轨道。

我们都要做“无烟青少年”做文明的主人!

让我们一起和家人幸福的生活，一起创造美好的未来吧!

吸烟的危害演讲稿篇4

尊敬的xx：

今天的讲话的题目是《吸烟有害健康吗?》。

据说吸烟也有三大好处：一，小偷不敢偷；二，狗不咬；三，不会老。

首先，抽烟的人，常咳嗽，晚上小偷偷东西的时候以为他没睡着呢，不敢偷。然后，因为咳嗽常弯腰，狗看见了以为要捡石头打它，所以不敢咬。最后，抽烟的人易患癌症，还不等衰老就挂了，所以不会老。

以上虽然是一个笑话，但已可窥其一斑。我是教数学的，就让我用一些具体的数据来讨论一下这个问题吧：

尼古丁是烟草中的主要成分之一，其具有很强的毒性。一支香烟中的尼古丁可毒死10只小白鼠，25支香烟中的尼古丁能毒死一头牛，如果采用静脉注射5支香烟的古丁可使人致死。

从大气污染的角度看，在一般通风不良而吸烟者又较多的地方，那里每一亳升烟雾里含有50亿个烟尘颗料，它是平常空气中所含尘埃微粒的5万倍。那里一氧化碳的浓度超过工业允许值的840倍。

每天吸烟5支-8支者，患肺癌、口腔癌或喉癌致死的机率，要比不吸烟的人大14倍；其易患食道癌致死的机率比不吸烟的人大4倍；死于膀胱癌、心脏病的机率也要大两倍以上；并且患上慢性支气管炎和肺气肿几率高达90%以上。

现在每年有约400万人死于由烟草制品引起的疾病，即每13秒钟就有一个人被烟草夺取了生命。

在未来20年中全球由吸烟所导致的死亡将增加3倍。到2020年，被烟草杀死的人数将超过其他任何一种疾病。在世界范围内，死于与吸烟相关疾病的人数将超过艾滋病、结核、车祸、自杀、凶杀所导致的死亡人数的总和。

而对于未成年人，数据更是惊人：据世界卫生组织调查小于15周岁便开始吸烟的青少年，比不吸烟的青少年肺癌的发病率增高了近27倍；大脑、身体发育也明显受到严重影响。

对于成年人吸一支烟等于减少了2分钟生命，而对于未成年人却要付出1小时的代价。

对于女性影响更是深远：首先，吸烟是美容的第一天敌；吸烟女性将比正常女性更易衰老，甚至提前5到10年长出皱纹、黄斑等；其次，女性吸烟更容易产生各种癌变，其患各种疾病的几率比吸烟男性还要高1.5倍。

吸烟有害健康吗?其实在每一包香烟的烟盒上都已写得明明白白——吸烟有害。正如专家所言，烟草是一种在正常使用过程中就会杀死消费者的产品。

在烟草流行背后还隐藏着一个不为人注意的重大阴谋。全球70%的香烟生产自发达国家，可70%的烟民却在发展中国家；在发达国家的烟草商因在本国受到限制与责难，所以他们千方百计地向发展中国家推销香烟，甚至诱惑青少年吸烟，许多人“误上贼船”的同时，而他们的腰包却赚得滚圆。正如以前林则徐所说：其祸，烈于洪水猛兽。

同学们，少年强则国强，少年弱则国弱。为了摘掉烟草大国的帽子，为了你自己的身体健康。我在此向大家发出两项呼吁：一、拒绝第一支烟；二、戒烟从今天开始。记住，没有烟雾的空气会更加清新，没有烟草的生命会更加绚烂!

我的讲话结束，谢谢大家!

吸烟的危害演讲稿篇5

smoking is a bad habit that does harm to smoker and others. many kinds of diseases and cancers are caused by smoking, such as tracheitis, lung cancer and many other diseases.

recent years, there are tens of thousands of people dying of smoking. but there still are many people enjoying smoking, because they think smoking is a kind of fashion and smoking is so cool, especially among teenagers.

in addition, smoking does harm to others as well. second hand smoking has been recognized harmful to other people.

even worse, it may cause more damages.

therefore, people should remember that smoking is harmful to others and those people who smokes should give up smoking as soon as possible.

翻译：

吸烟是个坏习惯，它对吸烟者和别人都有害。很多疾病和癌症是有吸烟引起的，比如说气管炎，肺癌还有很多其他疾病。近年来，成千上万的人死于吸烟。但是仍然有很多人喜欢吸烟，因为他们认为吸烟是一种时尚，很酷，特别是青少年。

另外，吸烟也会对别人有害。二手烟是公认的对别人有害的。更糟糕的是，它会带来更多伤害。因此，人们应该牢记吸烟有害他人，那些吸烟的人应该尽可能戒烟。

吸烟的危害演讲稿篇6

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！

吸烟的危害演讲稿篇7

“why do you want to smoke?”many people often ask questions like this.in recent years,there is a general tendency to more and more children also learn to smoke.they don't know the dangers of smoking,just think that smoking is cool, it's a trend.from the picture,we can come to a conclusion,smoking is equal to chronic suicide.

it is well known that a cigarette contains many chemical substances such as tar and nicotine.burning cigarettes can produce certain poisonous substances.therefore,smoking can harm not only smokers but also non-smokers around them.on the one hand,the hazardous chemicals will do harm to smokers’ lung cells and blood circulation,which can shorten their lifespan.on the other hand,non-smokers exposed to second-hand smoke are at high risk of many health problems.

to be brief,smoking is no less than chronic suicide,which destroys the health both smokers’ and people around them.people should try their best to give up smoking,for their own health, for the family.
