吸烟的危害演讲稿篇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.

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。
吸烟的危害演讲稿篇3
老师们，同学们：
大家早上好!今天我要讲话的题目是《吸烟有害健康》。 我们都知道香烟盒上都标有“吸烟有害健康”的字眼，但多数人还是选择了无视它，甚至对烟草趋之若鹜! 学生吸烟，在我校只是少数人的问题。但是学校却一再重拳出击，厉行禁烟，逼得少数小烟民们苦不堪言!他们三五成群，东躲西藏，和老师“打游击”，打一枪换一个地方，不怕熏，不怕黑，不怕臭。为了过一把烟瘾，他们一会儿躲进厕所，一会儿藏进街边小卖部，一会儿躲进宿舍，个别同学甚至躲到被子里。
学校为何要这般为难这些小烟民们呢?烟草究竟有多大危害呢?
世界卫生组织称烟草危害是当今世界最严重的公共卫生问题之一，人类健康所面临的最大危险因素。目前全球烟民总量已突破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4月7日定为第一个世界无烟日，以后固定为每年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生存环境。
据研究，一支香烟里含尼古丁可毒死一只小白鼠，而约一包香烟中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，点燃香烟时产生约5000种化合物，都是导致癌症的元凶。
世界卫生组织在发表一项声明中指出：“如今烟草已经成为全球第二大杀手。吸烟所产生的破坏比禽流感和地震还要严重。如果维持当前趋势不变，到2020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危害，为什么有众多人吸烟呢?
分析其原因主要有两个：一烟草中所含尼古丁令人上瘾，使人对它产生依赖，不容易戒掉；另一个原因大多数人还没有把吸烟看成一个丑陋，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，吸烟人群像滚雪球一样越滚越大，人们对它依赖也越来越强。
我国是世界上最大香烟生产国，也是最大香烟消费国。全世界三分之一以上香烟由中国人一口一口吸掉。而在我国烟民中，青少年又占了很大一部分。对青少年来说，吸烟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阶段，身体各器官系统还没有发育成熟，对各种有毒物质抵抗力不强，受烟雾毒害也就更深，甚至可以导致早衰，早亡。吸烟还可能使青少年养成不良生活习惯，诱发不良行为，甚至引发犯罪。
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，并劝说吸烟亲友尽量戒烟。毕竟，香烟对我们有害无益；毕竟，没有烟雾空气会更加清新，没有烟草生命会更加绚烂!我的讲话完毕，谢谢大家!
吸烟的危害演讲稿篇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!
吸烟的危害演讲稿篇5
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。
