吸烟的危害的演讲稿篇2

尊进的老师，亲爱的同学们：

大家好

5月31日是“世界无烟日”，今天我讲话的题目是：世界无烟日——献给孩子的爱。

同学们，提到“世界无烟日”，你们是否跟我一样，耳边有一个声音在呼喊：吸烟有害健康，请你远离香烟!

一根小小的香烟，在大家眼中是如此渺小，但如果你们真正了解到它的危害，就会瞪目结舌!下面就让我们来听一听香烟的自我介绍：

嗨，大家好!我叫香烟，世界上无人不知无人不晓，而且大家都特别喜欢我。尤其是男士，他们大都是我的“粉丝”。屈指算来，世界上约13亿人热衷于我，在中国大概也有3.5亿!你们别看我长得小，看起来微不足道，可我的本领可大了!告诉你们吧，我体内有4000多种化合物。怎么，你不相信?不是我自吹自擂，我们香烟个个都是最棒的，如果吸上一支，就会吸入几十亿个化合物颗粒，顿时就会精神抖擞。不过，你们吸入的颗粒中含有尼古丁、焦油、氨、苯等致癌物，其中仅仅焦油就含有几十种致癌物，尼古丁还会使人成瘾。听科学家说，一支香烟中的尼古丁就可以毒死一只小白鼠呢!大概是我太放肆的缘故，世界卫生组织专门对我进行了调查，据称全球每6.5秒就有一人因吸入我而失去生命，每年约500万人死于和我有关的疾病，还说我已成为继高血压之后的第二号杀手，有80%的肿瘤，75%的慢性阻塞性疾病和25%的冠心病都与我有关……我真的没有想到我会给我的“粉丝”带来这样大的伤害，我自己听了这可怕的事实都有一种心惊肉跳的感觉。大概是因为我太伤人了，人们便把5月31日定为“世界无烟日”。虽然我有些不开心，但看看我的劣迹，我还是决定保持沉默了。

同学们，听了香烟的自我介绍，不知道你们有什么感受，我想，你们一定和我一样，有一种毛骨悚然的感觉。看看你们周围的烟民吧：见面的时候，他们会热情地敬烟，一脸有福同享的表情——他们把这些含有毒物质的香烟当作一种交际工具，优哉游哉地享受着吸烟的暂时的快乐，可他们不曾想到，在他们享乐的同时，他的家人，他的朋友，还有周围一些无辜的人都受着烟雾的侵害。在通风不好的室内吸上两支烟，室内的空气污染就要比室外高出20倍。

烟可不是一个好东西。同学们，请你们从今天开始，将“烟的自我介绍”讲给身边的烟民们听，劝他们戒掉烟瘾，重新拥有健康的身体!谢谢大家!

吸烟的危害的演讲稿篇3

各位尊敬的领导和同事们：

大家好！

激情六月、阳光灿烂，在即将迎来建国xx周年的美好季节里，我们客运，也如同这火热的季节一样，安全形势逐步稳固、服务水平不断提升！今天我们在这里举行“我身边的安全故事”主题演讲活动，我是来自车队的列车员，首先，我祝各位领导和同事们大家生活开心，工作安心，一切顺心！我演讲的题目是《让“无忧草”真正“无忧”》。

说起“无忧草”，大家一定不会陌生，我们的列车广播每天都在宣传不吸烟车厢的管理，列车广播节目里那个吸烟的旅客给香烟取了个美好的名字叫做“无忧草”，还宣扬了吸烟的所谓种种好处：点燃一根小小的“无忧草”，腾云驾雾中，吸烟者“无限惬意、无忧无虑、悠哉悠哉”，未被熄灭的烟头被扔在了车厢里某个不易发现的角落，烟头的中心温度高达700℃～800℃，足以引燃列车卧具、备品和车厢角落里的废纸、垃圾等，从而引发火灾，看来，这“无忧草”在列车上并不是真正的“无忧”！

今年3月份，列车车体更换以后，在短短不到一个月的时间里，硬席车通过台、茶桌下、宿营车铺位格内蓝色的地面上就长上了黑色的斑点，这都是小小的烟头所烫伤的。这一点不但暴露出“不以为然”的人们对烟头威力的弱视，还暴露出我们乘务人员安全意识薄弱、标准化作业落实的漏洞。还有今年5月13日列车行李车着火，就是押运人员吸烟引发的火灾。

一个小小的未熄灭的烟头，威胁的'将是上千旅客的生命财产安全！

大家知道，因为我们国家国情的原因，我们目前还不能实现列车整体禁烟，在列车上，只能做到不吸烟车厢的管理，如何让“无忧草”在列车上真正“无忧”，作为一名列车员，在我值乘中，对不吸烟车厢的宣传管理是我工作的重要内容。

记得刚到客运段的时候我们进行列车消防安全培训，课堂上，教育科老师要求每位学员讲一件发生在自己身边的、最让自己感受深刻的因为吸烟引发的安全事故。这一下，课堂热闹了，小张讲同学家的被子被他爸爸吸烟给点着了，父子两人差点就over了。小李说他一个烟头弹到对面楼的阳台上，把人家晾晒的衣服都给烧了个洞，小王说自己在网吧里上网，烟头把电脑键盘给烧了个坑，破了100元钱的“财”才算消了“灾”……等大家讲完了。老师才对我们进行了不吸烟车厢管理教育培训，我们都深深体会到：在旅客列车上吸烟引发火灾，后果将不仅仅是一个洞、一个坑和破财消灾那么简单了。

令我记忆犹新的是，刚上车不久的一次值乘中，列车从三门峡开车，车厢里突然传来一股浓浓的烟雾味，我赶紧检查，发现是从车厢一头的垃圾桶里冒出来的烟，打开垃圾桶一看，原来是丢弃的没有熄灭的烟头引燃了桶里的废纸，我赶紧浇水扑灭了浓烟。事后，列车长对我进行了批评教育。我的心里面也感觉非常后怕，如果烟雾变成了明火该怎么办？飞驰的列车上，如果着火，火灾将会以每分钟10米的速度迅速蔓延，后果将不堪设想。

从陇亩田间到荆楚大地，无论时空怎么转移，“咔咔”声奏起，这首最熟悉的列车交响曲始终伴随着我。在路上，列车跨过了一条条江河，越过了一座座山川，如今，崭新的空调车代替了绿皮车，车体硬件设施提高了，卧具备品都焕然一新，创建服务文化，构建和谐车厢是我们的责任和义务。不吸烟车厢管理是车班安全文化创建的重要组成部分，一个和谐的车厢，安全文化的创建必然是互动的。

吸烟的危害的演讲稿篇4

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!

吸烟的危害的演讲稿篇5

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！

吸烟的危害的演讲稿篇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.
