吸烟的危害的演讲稿篇2

尊敬的老师，同学们：

五月三十一日是世界无烟日。但是这个节日似乎被人们渐渐淡忘了。抽烟的“魔爪”也伸向了初中生甚至小学生。烟，在我们的生活中无所不在。每年因为吸烟导致肺炎、肝硬化死亡的人呈上升趋势。吸烟变成了“杀人凶手”! 健康随烟而灭;病痛，伴烟而生。有多少生命可以重来呢?

目前全球吸烟人数约为11亿，估计到2025年这一数字将达到13亿至17亿。当一支烟被点燃，并被一口一口地吸入体内时，你可知道一袭白衣的“妖精”正顺着你的呼吸道，慢慢地开始了它的这场身体掠夺之战。香烟是魔鬼的契约，点燃香烟的一刹那，你也点燃了死亡的导火索。

医学研究表明，吸烟是心脑血管疾病、癌症、慢性肺病等多种疾病的诱发因素，吸烟已成为继高血压之后的第二号全球杀手。全球每年有500万人死于与吸烟有关的疾病，如果不加控制，这一数字到年时将达到1000万。长期吸烟者的肺癌发病率比不吸烟者高10倍至20倍，喉癌发病率高6至10倍，冠心病发病率高2至3倍，循环系统发病率高3倍。香烟燃尽自我，贻害众生。被动吸烟的'危害更大，每天平均1小时的被动吸烟就足以破坏动脉血管。一些与吸烟者共同生活的女性，患肺癌的几率比常人多出6倍。目前全球有13亿烟民，其中9亿人在发展中国家。吸烟者的人数，特别是青少年烟民的数量越来越多。中国约有3.5亿吸烟者，中国烟民正趋于低龄化，青少年吸烟人数高达5000万。调查还显示，在中国被动吸烟的主要受害者是妇女和儿童，尽管她们自己并不吸烟，但经常在家庭、公共场所遭受他人吸烟的危害。55%的15岁以上女性每天都遭受被动吸烟的危害。儿童由于缺乏自我保护能力，被动吸烟情况更为严重。

因此，控制烟草危害是一个具有长期性、艰巨性和复杂性的公共卫生问题。世界卫生组织提出“创建无烟环境”，也是在告诉公众，吸烟和被动吸烟是人类健康所面临的最大的但又是可以预防的危险因素，公众都有索取享有没有烟草烟雾污染的清洁空气的权利。只有“创建并享有100%无烟环境”，才能更好地保护人们免受烟草烟雾的危害。

健康是人全面发展的基础，关系千家万户的幸福。儿童、青少年是国家的未来，为青少年学生创造良好的无吸烟环境，不吸烟，不仅有益于学生身心健康的发展，而且对民族体质的增强和整体人群健康水平的提高以及社会良好风尚的建立都具有深远的战略意义。为此，我们倡议全体教职员工要积极维护“无烟学校”的创建成果，校内实行全面禁烟。积极宣传吸烟有害健康的科学知识，倡导并形成学生主动规劝家长、老师戒烟、禁烟的良好氛围，把禁烟纳入精神文明建设的轨道。

同学们、老师们，燃烧的是香烟，消耗的是生命，生命只有一次，怎能断送在香烟上?为了爱你和你爱的人，请远离烟草。

吸烟的危害的演讲稿篇3

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!

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。

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。
