吸烟危害的演讲稿篇1
“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.

吸烟危害的演讲稿篇4
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!
吸烟危害的演讲稿篇5
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!
吸烟危害的演讲稿篇6
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。
吸烟危害的演讲稿篇7
老师们，同学们：
大家好!
今年的5月31日是世界无烟日，主题是“卫生工作者和控烟”。相信每一个人都知道，烟草的危害是当今世界最严重的公共卫生问题之一，是人类健康所面临的最大的危险因素。目前全球烟民的总量已突破13亿人，每年因吸烟致死近500万人。为此，1987年11月联合国世界卫生组织建议将1988年的4月7日定为第一个世界无烟日，以后固定为每年的5月31日。开展这项活动，目的在于警醒世人吸烟有害健康，呼吁人们放弃烟草，为人类自己创造一个健康的生存环境。
那么烟草究竟有多大危害呢?
据研究，一支香烟里含的尼古丁可毒死一只老鼠，而约一包香烟中的尼古丁能毒死一头牛。每天吸一包香烟，相当于吸入了50-70毫克尼古丁，如果一次性地服用了这些量，人足以被置于死地。除尼古丁外，点燃香烟时产生的约5000种化合物，都是导致癌症的元凶。
世界卫生组织在今年发表的一项声明中指出：“如今烟草已经成为全球的第二大杀手。吸烟所产生的破坏比非典和最近的海啸还要严重。如果维持当前的趋势不变，到年，每年将有1000万人因吸烟而过早去世。”
既然烟草有如此可怕的危害，为什么有众多的人吸烟呢分析其原因主要有两个：一是烟草中所含的尼古丁令人上瘾，使人对它产生依赖，不容易戒掉;另一个原因是大多数人还没有把吸烟看成是一个丑陋的，既害人又害己的恶习。相反，认为这是一件很有派头，很潇洒的事情。因此，吸烟的人群像滚雪球一样越滚越大，人们对它的依赖也越来越强。
然而，烟草商们说：“我们生产的烟是给那些没有知识的人，年轻的人和愚蠢的人吸的。”
我国是世界上最大的香烟生产国，也是最大的香烟消费国。全世界三分之一以上的香烟是由中国人一口一口吸掉的。而在我国的烟民中，青少年又占了很大的一部分。对青少年来说，吸烟的危害远比想象中大得多，不仅会导致很多疾病，还会影响骨骼生长发育。这是因为青少年正处于身体迅速成长发育的阶段，身体的各器官系统还没有发育成熟，对各种有毒物质的抵抗力不强，受烟雾的毒害也就更深，甚至可以导致早衰，早亡。吸烟还可能使青少年养成不良的生活习惯，诱发不良行为，甚至引发犯罪。反吸烟已成为我国迫在眉睫的当务之急。为此，我国政府提出了在今后25年中，将我国的烟民总数减少1.1亿的总体目标。
为了积极响应政府的号召，更为了我们自己的健康，我们呼吁，全体同学都要自觉地远离香烟，并劝说吸烟的亲友尽量戒烟。毕竟，香烟对我们有害无益;毕竟，没有烟雾的空气会更加清新，没有烟草的生命会更加绚烂!
吸烟危害的演讲稿篇8
敬爱的老师，同学们：
大家好!
世界卫生组织于1987年做出决定，将每年的5月31日订为世界无烟日。此举告诫人们吸烟有损健康，呼吁世界“烟民”在该日停止吸烟或从此戒烟，并呼吁这一天所有商人不卖烟。
1990年，世界卫生组织选择了“青少年不要吸烟”作为本年世界无烟日的主题。在我国召开的第三个“世界无烟日”座谈会上，有关专家呼吁：控制吸烟应从青少年抓起，还强调控制青少年吸烟要从小抓起;教育部门要充分利用教育阵地，加强对学生的管理，要绝对禁止中小学生吸烟。据有关报刊报导，我国青少年吸烟率近年来不断上升。如果不加以控制，到2025年，我国每年死于吸烟的总人数将由现在每年10万人上升到200万人。据调查，青少年吸烟已成为我国一个不容忽视的社会问题，我国70%以上的吸烟者开始吸烟的年龄都在15～25岁之间。
为推动我国控制吸烟工作的深入开展，必须杜绝青少年吸烟现象。吸烟过多，会引起身体的不适。如：咳嗽、喘气不适……还会引起多种慢性疾病的发生。如：肺炎、癌症……一些人，朋友见面要抽烟，过节送礼也买烟，抽烟成了交际的工具。香烟盒子上明明刻着“吸烟有害健康”六个大字，不知道一些忠实的烟民朋友有没有看见。
总之，吸烟有害健康。大家戒烟吧!
