吸烟对下一代的影响论文范文

古代一直知道制作烟草的材料：菸草，但是数千年以来，我们的祖先并不把这个东西制作成香烟，并吸烟。1939年12月20日出版的《张建通讯》半月刊称：“中国之有烟叶栽种，早在汉朝以前。到了汉时，已设吏专管征税。”真正吸烟的历史是开始自明朝中期以后，清朝逐渐流行，到清朝更发展到抽古代大烟（当代称为毒品）境界。到了现在，吸烟成风，因此，“菸”字甚至直接改为了“烟”字，本来的读音也变成了“yan”。这并不是好事情。而且是一个巨大的可怕的行为。这里且不说众所周知的烟草有害的化学、物理分析，更不需要用所谓的临床调查说明烟草危害了多少生命，单从咱们祖先的看法就知道吸烟的危害。古人认为“烟”不是人类享受的东西。从烟字的造字法就可以知道。古代把烟字写作“”，最上面是一个宝盖头，左边是一个香袋加个火字，右边是一个祭祀的符号，那么是什么意思呢？本意是说：后人聚集在房屋里面，对着祖先的香炉点香火，然后祭拜自己的祖先。意思到这里已经很明白了，就是给咱们祖先的东西是专门产生“烟”的东西。“烟”成为了祭祀的主要用品。另外一个意思来说，世界分阴阳，阴界的祖先以吸收“烟”这些东西来当“食物”，后人以这样的方式尊敬祭拜祖先。后来咱们以前的祖先发现“菸”这种草最符合，因此祭拜祖先的最好“食物”就选择了浓烟滚滚、源源不断的“菸”。于是，“菸”专门成为了拜祖先的核心供品，并禁忌任何阳界人“摄食”。从某个意义来说，向别人敬香烟，本意就是把对方当作“先人”来对待，这也是祝对方快点到那个“世界”的意思。可是，有些人竟然接受，认为是好事情，于是吞云吐雾起来。这是很可怕的事情。即使是按照当代医学的分析，也说明香烟可以带来各种慢性病：香烟中有2540多种成分，燃烧后发生复杂的物理化学变化,产生的烟气中有400多种致癌物质，还有10多种会促进癌发展的物质,其中对人体危害最大的是烟碱、焦油、一氧化碳、氰化物及放射性物质。吸烟大为增加肺癌的机会，而肺癌是死亡率最高最难治疗的癌症，80%至90%的肺癌是由吸烟引起，30%由癌症引致的死亡是出于吸烟。

吸烟的危害说明文作文我在两、三岁时，外婆经常吸烟，得了气管炎。经过我和家人的'劝阻，外婆终于不吸烟了。我爷爷因为长期吸烟，而得了重病。从那以后，爷爷再也不吸烟了。这几天，我突然发现我的哥哥也吸烟，我和妈妈叫他不要抽，他下决心再也不抽了，我和妈妈也相信他。我看见有关资料上说：“一只香烟可产生五百毫升烟雾，烟雾中含有三千多种化学物质，其中二十多种被确认为致癌物。最早从烟草中提取出来的尼古丁，即使吸烟者成瘾也使吸烟者中毒。以后科学家又从香烟中分离出苯并芘和甲基肼，它们都是较强致癌物，长期吸烟就会得各类癌。吸烟也会污染环境，而且对下一代有影响。香烟还是一种慢性自杀的毒药。一支香烟可毒死一只老鼠，二十支香烟可毒死一头牛。”有资料表明：“有一个人连续吸了六十只烟，会当场死亡”。戒烟已成为世界性的潮流，所以联合国把每年的5月30日为“世界无烟日”我想：“要是世界上没有人抽烟，那该有多好。”篇一：吸烟的危害作文400字创无烟环境，过健康美好的生活——是我们每个人的理想。很多公共场所都贴着禁止吸烟的标志。我们学校也在创建无烟校园呢！有一天，我正要走进电梯的时候，一股难闻的气味扑鼻而来，把我给呛到了，连续咳了好几次，我东张西望地寻找气味是从哪里来的？原来，是一位叔叔手中拿着香烟，我很有礼貌地说了一声叔叔好，叔叔夸我是个懂礼貌的好孩子，我非常开心。后来我亲切地对叔叔说：“叔叔请你不要吸烟，吸烟对自己有危害，而且你没注意到牌子上面有写吗？”叔叔说：“我从来都没注意过，不过谢谢你小朋友，叔叔以后不再吸烟了。”为了防止越来越多的人吸烟，仅仅靠一个人的力量是不够的，我们应该一起团结起来，去掉这一大不良的'坏毛病。现在，我郑重的呼吁大家，放下手中的烟吧！让我们一起和家人幸福的生活，一起创造美好的未来吧！

英语高中选修六不是有小提到了一下。

吸烟有很多危害，下面简单例举9条:一、吸烟导致血栓，引发各种心脏病吸入香烟中的一氧化碳会降低血液吸收氧气的能力。尼古丁能使心跳加快，血压升高，心脏的承受能力减弱，心肌缺氧引起冠状动脉梗塞，心脏局部缺血（或心胶痛）促使动脉粥样化累积，许多心脏疾病开始发生。二、吸烟对脑部的损害吸烟会引致多种脑部疾病，会减低循环脑部之氧气及血液，引致脑部血管出血及闭塞，而导致麻痹、智力衰退及中风。三、吸烟对口腔的损害吸烟可导致口腔癌和喉癌。香烟中的焦油及烟雾的热量会使唾液腺发炎，味蕾受损，口味和嗅觉能力大大减弱。四、吸烟对肺部的损害吸烟能引致支气管上皮细胞的纤毛变短和不规则及其和运动发生障碍，降低局部性抵抗力，容易受到感染。吸烟会引致肺癌。五、导致早衰香烟中的尼古丁能刺激微血管发生痉挛收缩，使皮肤供血供氧不足，影响正常的新陈代谢，加速衰老六、月经失调与痛经烟草中的尼古丁能降低女性性激素的分泌量，从而干扰与月经有关的生理过程，使月经初潮推迟、经期紊乱，更年期综合征提前到来，闭经或经量稀少，严重的甚至影响受孕七、分娩婴儿的畸形率明显增高吸烟女性分娩婴儿的畸形率是不吸烟妇女的2-3倍，其中患先天性心脏病的比例为73%，患白血病的危险要高一倍。八、减少乳汁分泌吸烟能使乳汁分泌减少，尼古丁还可随血液进入乳汁。每天吸烟10-20支的妇女，在1公斤乳汁中可分离毫克的尼古丁。这对婴孩健康是严重威胁。九、易患风湿性关节炎吸烟女性患早发型风湿性关节炎的机会几乎是不吸烟者的两倍。

吸一支烟后，你的身体会立即发生以下变化：(1)心率加快，血压升高；2）咳嗽；3）肺活量降低，呼吸不良；4）手指、脚趾、皮肤温度降低；5）胃酸增加；6）手指颤抖；7）泌尿减少；8）食欲味觉和嗅觉降低；9）眩晕，眼睛流泪；10）降低记忆力 吸烟可影响身体的许多部分，最直接的影响主要是两大系统：呼吸系统和循环系统。（1）呼吸系统1）吸烟可使肺功能受损，痰液及有毒物质不能排除，细菌容易繁殖。长期刺激下，形成慢性支气管炎和慢性呼吸道阻塞，进一步可发展肺气肿、冠心病。2）烟焦油内大量的致癌物附着在呼吸道，长期刺激下可引起呼吸道的各个部位的癌症，以肺癌为主，其他还有口腔癌、唇癌、喉癌等。（2）吸烟对循环系统的影响1）香烟中的尼古丁可使心率增快，同时收缩血管，是血压升高；2）血管长期处在收缩状态，导致血管硬化，管腔变窄，输送的血量减少；3）营养心肌的冠状动脉硬化后，使心肌得到的氧供应减少，心肌细胞发生变性坏死，导致冠心病；4）营养脑细胞的动脉血管硬化，血管壁弹性减弱，可诱发脑血管破裂出血，管腔变窄，甚至脑血栓形成和脑栓塞，导致“脑中风”；5）持续、大量的吸入一氧化碳使机体缺氧，可加重以上病变。美国科学家根据近年的研究结果，从健康角度，再次向人们提出了戒烟的理由，以期引起世人的重视。 (1)吸烟不但危害自己的健康，而且污染环境，危及周围的不吸烟者，特别是妇女和儿童。许多人知道吸烟损害健康，却不知道吸烟危害健康的严重性。您该戒烟了！ (2)吸烟易导致失眠 与非烟民相比，吸烟者更难以入睡及熟睡。香烟中的尼古丁能干扰快速动眼睡眠，造成睡眠质量下降。烟民还较易打鼾，白天易疲乏打瞌睡。 (3)烟民易患糖尿病、心脏病 一项对42 000名男子的研究发现，与不吸烟的人相比，吸烟者发生非胰岛素依赖型糖尿病的可能性高出1倍多。 30~40岁的烟民心脏病发作者较同龄不吸烟者高5倍。英国一项针对46 000例吸烟者的调查首次发现，年轻烟民心脏病发作的危险明显增加，而吸含中等量焦油香烟者又较吸低等量焦油香烟者的心脏病发作率高出10%。 (4)戒烟能降低卒中的危险 英国科学家对7 264名中年男性进行研究证实，大量吸烟者（每天多于1包），戒烟5年内可使卒中危险减半。而吸烟量每天少于1包者，戒烟5年内可使卒中危险降至未吸烟者水平。 (5)长期吸烟能引起乳腺癌 研究表明，妇女吸烟达30年者，较其他妇女发生乳腺癌的危险性高60%，前者发生乳腺癌的平均年龄为59岁，而不吸烟者为67岁。 (6)妇女吸烟会使轻度甲状腺病加重 吸烟会明显加重妇女原患有的轻度甲状腺疾病，可能导致甲状腺衰竭。研究还发现，妇女吸烟者的平均血清HDL（好胆固醇）比不吸烟者低，故前者心脏病发作明显高于后者。 (7)吸烟引起皱纹 一项对1 000名40~49岁人群的研究发现，女烟民出现明显皱纹者为女性非烟民的3倍，原因是吸烟会损伤那些与保持皮肤弹性至关重要的血管结缔组织。 (8)吸烟引起肺癌高发 过去一直认为，男性死于肺癌与吸烟密切相关，近来研究发现，妇女因吸烟死于肺癌者也显著增加。 吸烟若干年后戒烟是安全的观点是错误的。已戒烟的烟民中发生肺癌危险的持续时间较以往认为的长得多。一项研究发现，肺癌病人中有一半为已戒烟的人。这不是说戒烟无作用，而是告诫人们，只有越早戒除烟瘾才越安全。 (9)戒烟的最佳理由是树立良好榜样。 由于50岁死于心脏病者中的80%是由吸烟引起的，所以，父母戒烟对下一代有榜样作用。家庭与社会都应对青少年进行吸烟有害的宣传教育，研究证明，如在19岁前不染上吸烟恶习，则以后成为烟民的可能性很小。After cigarette smoke, your body will immediately the following changes: (1) speed up the heart rate, blood pressure; 2) cough; 3) to reduce lung capacity, breathing bad; 4) fingers, toes, skin temperature; 5) to increase gastric acid; 6) trembling fingers; 7) urinary reduced; 8) loss of appetite reduce the senses of taste and smell; 9) dizziness, eye tears; 10) to reduce memory Smoking can affect many parts of the body, the most direct impact on the two major systems: respiratory and circulatory system. (1) respiratory 1) Smoking can damage lung function, sputum and toxic substances can not be ruled out, bacteria reproduced. Long-term stimulation, the formation of chronic bronchitis and chronic obstructive airway, and further to the development of emphysema, coronary heart disease. 2) large quantities of tar smoke carcinogens attached to the respiratory tract, long-term stimulation can cause various parts of the respiratory tract cancer, lung cancer mainly Other oral cancer, lip cancer, larynx and so on. (2) the impact of smoking on the circulatory system 1) the nicotine content in cigarettes will enable faster heart rate, while systolic blood vessels, is high blood pressure; 2) blood vessels in the long-term contraction, leading to hardening of the arteries, luminal narrowing, reducing the transmission of blood; 3) nutrition myocardium after coronary artery, so that myocardial oxygen supply has been reduced, myocardial cell degeneration and necrosis, resulting in coronary heart disease; 4) Nutrition brain cells of artery hardening of the arteries, weakening of the vascular wall elasticity can be induced by cerebrovascular bleeding, luminal narrowing, and even cerebral thrombosis and cerebral embolism, resulting in "stroke"; 5) continued, a large number of inhaled carbon monoxide to make the body hypoxia, can increase the above diseases . . scientists in recent years, according to research findings, from a health perspective, people once again to put forward a reason to quit smoking, with a view to arouse the people of the world attention. (1)Smoking not only endanger their own health, but also pollute the environment, endanger the surrounding non-smokers, especially women and children. Many people know that smoking damages health, but he did not know the seriousness of the health hazards of smoking. You quit smoking! (2)Smoking easily lead to insomnia, compared with non-smokers, smokers fall asleep and sleep more difficult. Nicotine in cigarettes can interfere with REM sleep, resulting in a decline in the quality of sleep. Smokers also more prone to snoring, daytime fatigue easy to doze off. (3)Smokers susceptible to diabetes, heart disease, a man's 42,000 study found that with the non-smokers compared to smokers occurred in non-insulin-dependent diabetes mellitus the possibility of higher than 1 percent. 30 ~ 40-year-old author of smokers suffered a heart attack than non-smokers of the same age 5 times high. United Kingdom A 46 000 cases of smokers in the survey found for the first time, young smokers the risk of heart attack increased significantly, while the volume of smoke containing medium tar cigarettes than those who smoke low-tar cigarette volume of the heart attack rate by 10 %. (4)Quitting smoking can reduce the risk of stroke, British scientists 7 264 middle-aged men study confirmed that a large number of smokers (more than 1 pack per day), 5 years to quit smoking can halve the risk of stroke. And smoking less than 1 pack per day, and 5 years to quit smoking can reduce the risk of stroke is not the level of smokers. (5)Long-term smoking can cause breast cancer studies have shown that women who smoke 30 years than any other woman to have a high risk of breast cancer 60 percent, which occurred in breast cancer, the average age is 59 years old, rather than for the 67-year-old smokers . (6)Smoking women with mild thyroid disease may increase the smoking would be a clear increase indigenous women suffer from mild thyroid disease may lead to thyroid failure. The study also found that women smokers, the average serum HDL (good cholesterol) lower than non-smokers, the former heart attack was significantly higher than the latter. (7)Smoking wrinkles caused by a 1 000 40 ~ 49-year-old population study found that female smokers noticeable wrinkles for female non-smokers 3 times is because smoking will damage those essential to maintain skin elasticity vascular connective tissue. (8)High incidence of lung cancer caused by smoking has been that men die of lung cancer and smoking is closely related to the recent study found that women die from lung cancer due to smoking also increased significantly. After a number of years to quit smoking is a safe point of view is wrong. Smokers to quit smoking has occurred in the duration of the risk of lung cancer than previously thought much longer. One study found that half of patients with lung cancer for people who have quit smoking. This is not to say no role to quit smoking, but warned that only the sooner the more security to kick the habit. (9)The best reason to quit smoking is to set a good example. As the 50-year-old who died of a heart attack 80% caused by smoking, so parents have to quit smoking as role models for the next generation. Family and community to deal with young people to carry out publicity and education on the hazards of smoking, research has proved that if the 19-year-old former non-infected with this nasty habit, then after a very small possibility of becoming habitual smokers.
