演讲稿的内容要根据演讲的主题来思考，不同类型、不同内容的演讲稿，它的结构方式也各不相同，以下是小编精心为您推荐的吸烟的危害的演讲稿6篇，供大家参考。
各位领导、老师、同学们：
大家早上好！
吸烟危害健康，这句话无论是在家里，在学校里，还是社会中，都被我们听过很多遍了。可是，吸烟到底有哪些危害呢？许多同学对此却不是太清楚。
正是因为吸烟有着如此巨大的危害，在许多国家都成立了民间反烟组织，甚至就在许多国家的政府也都纷纷下令禁止在公共场合吸烟，以抑制烟民的热情。然而，就是在今天这样一个全球上下一片反烟之声的时代里，我们学校的少数同学却正在尝试着吸烟，或许，他们自认为自己的行为很酷，很吸引人注目。可是，当他们在走廊的转角，在无人的车棚，甚至是在厕所里抽烟时能睁开眼睛好好看一看的话，就不难发现周围同学的震惊，反感和不屑。的确，香烟或许能给人以逃避现实中不顺的机会，可是我们正处在生长发育期，如果此时抽烟的话，不但会引发诸多疾病，还会干扰我们身体的正常发育。长期如此的话，大量的尼古丁甚至还有可能诱导器官的畸变，使人发育畸形，这都是我们为一时之快所付出的代价，更何况，科学研究已经证实：因为青少年的呼吸道与神经系统尚未完全发育，此时吸烟除了使人的喉咙肿痛，干涩外，不会给人带来任何舒适感。所谓的“吸烟能给青少年减轻压力”只是一句天大的谎言而已。
同学们，吸烟对我们有百害而无一利，为了我们自己的将来，也为了别人的明天，让我们携起手来，一同抵制吸烟吧！当有人向你递上香烟时，请有礼貌而坚定的拒绝；当看到亲朋好友吸烟时，请勇敢地走上前去制止他们；当看家陌生人在吸烟时，也请礼貌地向他宣传吸烟的害处。同学们，抵制吸烟不仅需要国家、政府的努力，更需要我们的支持，让我们从细节做起，从生活中的一点一滴做起吧！我相信，当真正的无烟社会到来时，受益的一定会是我们所有人！
“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.
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!
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.

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。
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。
亲爱的老师、同学们：
大家好！
5月31日是世界无烟日，今天我的演讲的主题是：世界无烟日关爱儿童。
同学们，提到“世界无烟日”，你们是否跟我一样，耳边有个声音在喊：吸烟有害健康，请你远离香烟！
一支小小的香烟，在每个人的眼里是那么的渺小，但如果你真的明白它的危害，一定会瞠目结舌！让我们来听一听香烟的自我介绍：
嗨，大家好！我的名字是香烟。每个人都认识我，也都很喜欢我。尤其是男人，是我的“粉丝”。
全世界约有13亿人喜欢我，在中国约有3.5亿人！虽然我长得小，看起来很渺小，但我的能力可是很大！
说实话，我体内有4000多种化合物。什么，你不相信吗？我不是自吹自擂。我们香烟都有最好的。
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。
可能是因为我太放肆，世界卫生组织对我进行了调查，据说全球每6.5秒一个人因为吸烟而失去生命，每年大约有500万人死于和我相关的疾病，还说我是高血压之后的第二号“杀手”，80%的肿瘤，25% — 75%的慢性阻塞性疾病和冠心病都与我有关……
我真的没有想到我会给“粉丝”带来这么大的伤害，我听到这个可怕的数字时，我有一种恐慌的感觉。
也许是因为我的伤害，人们选择了5月31日作为世界无烟日。虽然我有点不高兴，但看看我的坏行为，我决定保持沉默。
同学们，听了香烟的自我介绍后，我不知道你们有什么感觉，我想，你们一定像我一样，有一种恐惧感。看看你周围的吸烟者：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带来的短暂的快乐。
但是他们从来没有想到，在他们的快乐同时，他的家人、朋友和一些无辜的人周围弥漫着烟雾。在通风不良的房间里抽两支烟，那里的`空气污染是室外的20倍。
烟不是个好东西。同学们，请从今天起，将“吸烟自我介绍”讲给身边的吸烟者听，劝他们戒烟，拥有有一个健康的身体！
谢谢大家！
