吸烟的危害的演讲稿篇2

各位老师、同学们：

早上好!

今年的5月31日，是世界卫生组织发起的“世界无烟日”，今年的主题是：“烟草业干扰控烟”，口号是：“生命与烟草的对抗”。目前，随着全球范围出现吸烟年龄降低的趋势，作为烟草消费大户的我国，情况尤为严重。

医学研究证明，吸烟是心血管疾病、癌症、慢性阻塞性肺病等多种疾病的行为危害因素，已成为继高血压之后的第二号健康杀手。由于青少年正处于生长发育阶段，各器官系统还未发育成熟，对各种有毒物质的抵抗力不强，受烟雾的毒害也就更深。吸烟不仅损害青少年正常生长发育、降低机体免疫力，同时危害大脑，使思维变得迟钝，记忆力减退，甚至导致早衰、早亡。吸烟还可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。

吸烟的危害是众所周知的，可为什么还有那么多青少年也加入到吸烟大军中来呢?因为虚荣心和错误的价值观，还有些是好奇或受同伴影响。另外，青少年对于吸烟的危害性基本不了解，而香烟店也大开绿灯。当然，有些青少年是因为不好意思拒绝别人递来的香烟。因此青少年应培养正确的审美心理，树立高尚的价值观念，牢记以下几点：

1、从我做起，远离烟草毒害，拒吸第一支烟，养成良好的健康卫生习惯和文明健康生活方式。

2、从在校做起，积极帮助身边的同学戒烟，推行无烟教室，建设清洁卫生的无烟学校。

3、从在家做起，说服家里的长辈和亲戚戒烟，创建健康和谐的无烟家庭。

4、从身边做起，主动帮助受烟草危害的朋友们，踊跃参与公共场所禁烟宣传活动，在全社会营造文明健康的无烟氛围。

青少年正面临着一个重大的选择：你愿意成为未来的吸烟者吗?你希望成为一个疾病缠身的人吗?如果你选择健康，就要充分相信自己完全可以拒绝第一支烟的诱惑。只要不吸第一支烟，你就可以主宰自己、赢得健康。

烟雾袅绕并不是时尚，嘴叼白棍亦非潇洒。

同学们，让我们马上行动起来，从今天做起，“拒吸第一支烟，做不吸烟的新一代”，为创造一个无烟的生存环境而共同努力!

谢谢!

吸烟的危害的演讲稿篇3

尊敬的各位老师，亲爱的同学们：

你们好!

你可知道“点燃香烟的一刹那，你也点燃了死亡的导火线”?

你可知道“现在吞云吐雾，以后病痛缠身”?

你可知道“抽烟等于燃烧生命也等于燃烧时间”?

你可知道“抽烟等于燃烧金钱也等于燃烧了一部分衣食住行”?

你可懂“健康随烟而灭!有多少生命可以重来?”

健康，随烟而逝；病痛，伴烟而生!

吸烟的危害，人人皆知。全世界每年因吸烟死亡达250万人，吸烟是人类的第一人为杀手。研究表明，吸烟是导致呼吸道疾病的主要原因之一，吸烟者的平均寿命比不吸烟者少20年。

吸烟对青少年的影响更大。青少年时期，身体器官还没有发育成熟，抵抗力较弱，人体细胞对致癌物质更加敏感，青少年吸烟可直接导致脱发、听力下降、身体矮小、记忆力衰退，严重影响青少年的身心健康。况且，吸烟要耗费一定的钱财，用的都是父母的血汗钱，我们的父母绝不希望看到自己的孩子成为一个骨瘦如柴精神萎靡的香烟受害者!

吸烟不仅有害于健康，还容易导致青少年的堕落，因为吸烟还会导致个别学生犯罪。为过烟瘾铤而走险，走向犯罪的例子并不罕见。

我们是祖国的花朵，东方的曙光，肩负着振兴中华的使命，我们的未来任重而道远。为了我们的使命和重任，我们杜绝吸烟!

20xx年5月31是世界第xx个世界无烟日。作为青少年的我们，要远离烟草，拒吸第一支烟----净化空气，保护环境。

禁止青少年吸烟不仅是一个健康问题，也是一个社会问题；不但家长应该重视，学校和社会均不能掉以轻心。为了祖国的未来，每一个人都有责任保护下一代的健康；为了祖国的未来，我们应该珍惜自己的身体，珍惜自己的年华，拒吸第一支烟，做不吸烟的新一代!

任何一棵大树都是由小苗逐渐长成，任何大错都是由一个个小错组成，此所谓习惯养成。如果你今天抽一支烟，认为无所谓，明天再抽一支烟，也无谓，那么，后天，抽烟就会成为你的习惯。因此，我们坚决反对不抽烟的同学接受第一支香烟。在此，我向全体同学发出倡议，摒弃吸烟这一不良的行为习惯，拒绝吸烟，从我做起，从今天做起，从拒绝第一支香烟做起，追求健康、文明的生活方式，让烟蒂在校园销声匿迹!

为此，我们应该努力做到以下几点：

一、牢固树立消除烟害人人有责的观念。

二、提高自控能力，抵制诱惑，拒绝第一支烟。

三、以远离烟草为荣，以接近香烟为耻。

四、已经吸烟者要有坚强的意志和信心戒烟。

五、积极主动地向家人、亲友宣传吸烟有害健康的知识，规劝他们戒烟、控烟。

明智的人，学会用金钱买健康，而不是用金钱买死亡。

香烟本来就‘虚无缥缈’，不如让它从未发生!

燃烧的是香烟，消耗的是生命。

吸烟是你最简单的快乐，也让你最彻底地哭泣!

小小一支烟，危害万万千。

境由心生，戒烟之勇自在娇子

鹤舞白沙，戒烟之心永远飞翔

吸烟几时止?美景几时还?青春何能驻?生命何与共?只愿君能禁吸烟，盼回“无烟好世界”!请把火柴留给你的生日蜡烛，而不是香烟。

吸烟的危害的演讲稿篇4

today smoking is a widespread habit ali over the world. not only the old, the youth, but also middle school students have been engaged in smoking. many of them think that smoking is a smart symbol.

however, smoking is harmful to one’s ,health. it contributes a lot of lung cancer, from which many people have died in the past years. it can also cause many other diseases. in a word, if you smoke, you do have a much greater chance of losing your health. furthermore, scientific research shows that smoking is not only harmful to smokers themselves, but also a threat to public health, especially to women and children. therefore, many countries have made laws forbidding smokers to smoke m public places such as cinemas, stations, hospitals, and so on giveup smoking! if you don’t smoke, don’t start. give upsmoking for the sake of your health, for the sake of your family, and for the sake of the whole world.

吸烟的危害的演讲稿篇5

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!

吸烟的危害的演讲稿篇6

smoking is very popular among chinese people. nowadays, the number of smokers during teenagers is increasing. some treat smoking as fashion and follow such bad behavior. though many people have been educated the danger of smoking, they still do not fear it.

吸烟很受中国人的欢迎。如今，青少年吸烟者的数量与日俱增。有些人把吸烟当作时尚，追逐这样的不良行为。尽管许多人都被教育过吸烟的`危害，但是他们并没因此而却步。

it is known to all that cancer has been the killer and the researches found that smoking for a long time will be easy to get cancer. i remembered my hometown, where people smoked a lot, especially the old generation, and they formed this bad act when they were young. then for a time, many people died of cancer. people started to worry and they found that these people were heavy smokers.

众所周知，癌症是人类头号杀手，而且研究发现，长时间吸烟很容易患上癌症。我记得在我的家乡，吸烟的人很多，特别是老一辈，他们在他们年轻的时候就养成了这个习惯。然后有一段时间，很多人死于癌症。人们就开始担心了，后面他们发现这些人都是重度吸烟者。

the sad thing is that many teenagers smoke at their young age, and they feel cool to do it. some adults smoke to relieve their pressure. no matter what kind of reasons, the fact is that smoking not only hurt themselves, but also hurt other people, because we know that second hand smoke is harmful, too. for everybody’s health and to live a better life, smoking should be stopped.

可悲的是，许多青少年在年轻的时候就吸烟，他们还觉得很酷。一些成年人用吸烟来缓解他们的压力。不管出于什么样的原因，事实是，吸烟不仅伤害自己，还伤害了别人，因为我们都知道二手烟也是有害的。为了每个人的健康以及生活得更美好，我们应该停止吸烟。

but there are a lot of reasons not to smoke. smoking does harm to our health.it is dangerous to our heart and lung. a lot of diseases are caused by cigarettes.cigarettes also have terrible smell.

therefore, no smoking in public is a strict regulation in many countries.

and the most important thing is that once you come into addicitive,it's hard to get rid of it. so,we must keep far from the cigarette——for everybody's health.

翻译：

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。
