吸烟的危害的演讲稿篇2
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!
吸烟的危害的演讲稿篇3
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。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！
吸烟的危害的演讲稿篇5
“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.

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。
