吸煙的危害作文

吸煙的危害作文1

　　當(dāng)前，吸煙的現(xiàn)象隨處可見(jiàn)。有的人把香煙當(dāng)成了我們兒童平日里的零食，有的人由吸煙轉(zhuǎn)向了吸毒，還有的人因?yàn)槲鼰煻�被剝奪了生命。雖然煙盒上都標(biāo)著“吸煙有害健康”，但都被吸煙的人們視而不見(jiàn)、渾然不顧。

　　吸煙的人們，你們可知道吸煙的危害有多大嗎？煙草中含有大量的有毒物體，煙燃燒時(shí)所產(chǎn)生的煙氣中，大約含有一千多種對(duì)人體有害的成分，其中尼古丁危害最大。一支香煙中含有的尼古丁足以毒死一只小白鼠。吸煙還容易患各種疾病，如肺癌、胃癌，食道癌及肺氣腫等等。根據(jù)世界衛(wèi)生組織提供的資料顯示，世界上每年約有250萬(wàn)人死于吸煙引起的疾玻也就是說(shuō)，每13秒鐘就有一個(gè)人被煙草奪去了生命，這是一個(gè)多么驚人的數(shù)字呀！

　　吸煙不僅危害自己的身體健康，還會(huì)使周圍的人被二手煙感染，不得不“被動(dòng)吸煙”，損害他人健康，這也是一種很不文明、很不道德的行為。

　　如果說(shuō)吸煙對(duì)于成年人來(lái)說(shuō)是“慢性自殺”，那么對(duì)青年人來(lái)說(shuō)危害就更大了。青少年兒童吸煙后，會(huì)突然出現(xiàn)頭昏現(xiàn)象，腳站立不穩(wěn)，咳嗽、多痰等癥狀出現(xiàn)更為普遍。由于煙草對(duì)人的毒害不是一下子全都表現(xiàn)出來(lái)的，所以潛伏的危險(xiǎn)性更大。

　　我呼吁：吸煙的人們，不要再讓煙草剝奪自己那寶貴的生命了，放棄吸煙，戒煙吧！

　　吸煙的`危害盡人皆知，但“吸煙”仍然成為當(dāng)今一個(gè)極為普遍的現(xiàn)象。從年邁的爺爺、奶奶到十幾歲的青年都有“人手一支煙”這種不良嗜好。香煙，竟有這樣的魔力，讓癮君子如此迷戀。禁煙，竟有這樣的困難，讓戒煙者痛苦萬(wàn)分。

　　記得，我小時(shí)候就看過(guò)姥爺吸煙的模樣。據(jù)說(shuō)，姥爺已經(jīng)有幾十年的“煙齡”了。他老人家常常右手持煙，叼入口里深吸一口，那樣子別提多滿足、自在了。然后，幾個(gè)白色的煙圈便從他嘴里慢慢地吐出來(lái)，可又從兩個(gè)鼻孔里吸了回去，就這樣進(jìn)進(jìn)出出，好似龍王爺吞云吐霧一般。到最后，濃濃的煙霧又從他嘴里噴薄而出，空氣里立刻彌漫著一股煙草刺鼻的辣味。我站在一旁，被姥爺吐出的“二手煙”嗆得不停地咳嗽，連忙沖他大喊：“姥爺，別吸煙了！別吸煙了！”姥爺卻手一揚(yáng)，滿不在乎地笑了笑，嘴里不經(jīng)意地露出了黃斑斑的牙齒，說(shuō)：“丫頭片子管什么！我身體好著呢，能出啥事兒！”說(shuō)著，又掏出一支煙，美滋滋地遞到嘴邊。有時(shí)姥爺煙癮上來(lái)了，多吸了幾支，不免遭姥姥埋怨�！澳阊侥�，唉，讓人怎么說(shuō)呢。說(shuō)了多少次“吸煙有害健康”，你怎么不聽(tīng)勸呢？”姥爺卻仍不當(dāng)回事：“飯后一支煙，身體賽過(guò)活神仙，沒(méi)事沒(méi)事�！闭f(shuō)話間又去吐煙圈去了。后來(lái)，在我上一年級(jí)的時(shí)候，姥爺因?yàn)槲鼰熯^(guò)多，整天咳嗽個(gè)不停，愁眉不展。我知道，如果姥爺早點(diǎn)聽(tīng)從我們的忠告，把吸煙的陋習(xí)戒掉，現(xiàn)在也不至于如此痛苦。

　　據(jù)有關(guān)權(quán)威報(bào)告說(shuō)，全世界每年因吸煙死亡達(dá)250萬(wàn)人之多，煙是人類第一殺手。自覺(jué)養(yǎng)成不吸煙的個(gè)人衛(wèi)生習(xí)慣，不僅不益于健康，而且也是一種高尚公共衛(wèi)生道德的體現(xiàn)。在吸煙的房間里，尤其是冬天門窗緊閉的環(huán)境里，室內(nèi)不僅充滿了人體呼出的二氧化碳，還有吸煙者呼出的一氧化碳，會(huì)使人感到頭痛、倦怠，工作效率下降，更為嚴(yán)重的是在吸煙者吐出來(lái)的冷煙霧中，煙焦油和煙堿的含量比吸煙者吸入的熱煙含量多1倍，苯并芘多2倍，一氧化碳多4倍，氨多50倍。聯(lián)合國(guó)也因此特別制定了每年的5月31日為“世界無(wú)煙日”。

　　“吸煙有害健康”這句警示語(yǔ)我們耳熟能詳，可見(jiàn)吸煙真是百害而無(wú)一利呀。讓我們遠(yuǎn)離煙草，擁有一個(gè)無(wú)煙的童年吧！

吸煙的危害作文3

　　有關(guān)醫(yī)學(xué)研究表明，吸煙是心腦血管疾病、癌癥、慢性阻塞性肺病等多種疾患的行為危害因素，吸煙已成為繼高血壓之后的第二號(hào)全球殺手。據(jù)統(tǒng)計(jì)，全球每年有500萬(wàn)人死于與吸煙有關(guān)的疾病，如果不加控制，這一數(shù)字到20xx年時(shí)將達(dá)到1000萬(wàn)。有資料表明，長(zhǎng)期吸煙者的肺癌發(fā)病率比不吸煙者高10倍至20倍，喉癌發(fā)病率高6至10倍，冠心病發(fā)病率高2至3倍，循環(huán)系統(tǒng)發(fā)病率高3倍，氣管類發(fā)病率高2至8倍。被動(dòng)吸煙的危害更大，每天平均1小時(shí)的被動(dòng)吸煙就足以破壞動(dòng)脈血管。一些與吸煙者共同生活的女性，患肺癌的幾率比常人多出6倍。目前全球有13億煙民，其中9億人在發(fā)展中國(guó)家。吸煙者的人數(shù)，特別是青少年煙民的數(shù)量越來(lái)越多。中國(guó)約有3.5億吸煙者。20xx年，中國(guó)男性吸煙率為66%，女性吸煙率為3。08%。中國(guó)煙民正趨于低齡化，青少年吸煙人數(shù)高達(dá)5000萬(wàn)。

　　與1984年相比，20xx年開(kāi)始吸煙的年齡提前了4－5歲，其中男性由22歲降至18歲，女性由25歲降至20歲。

　　分別于1984年、1996年和20xx年進(jìn)行的三次全國(guó)吸煙流行病學(xué)調(diào)查顯示，中國(guó)青少年的吸煙率呈上升趨勢(shì)，目前中國(guó)青少年吸煙人數(shù)高達(dá)5000萬(wàn)。

　　中國(guó)是煙草生產(chǎn)和消費(fèi)大國(guó)，生產(chǎn)和消費(fèi)均占全球三分之一以上。目前，中國(guó)約有3。5億吸煙者。20xx年，中國(guó)男性吸煙率為66%，女性吸煙率為3。08%。與1996年相比，盡管吸煙率略有下降，但是隨著中國(guó)總?cè)丝诘脑黾�，吸煙人�?shù)仍然增加了3000萬(wàn)。

　　調(diào)查還顯示，在中國(guó)被動(dòng)吸煙的主要受害者是婦女和兒童，盡管她們自己并不吸煙，但經(jīng)常在家庭、公共場(chǎng)所遭受他人吸煙的危害。55%的15歲以上女性每天都遭受被動(dòng)吸煙的危害。兒童由于缺乏自我保護(hù)能力，被動(dòng)吸煙情況更為嚴(yán)重。

　　據(jù)衛(wèi)生部疾病控制局副局長(zhǎng)孔靈芝介紹，吸煙是造成多種慢性病的重要因素之一。20xx年中國(guó)由吸煙導(dǎo)致的死亡人數(shù)近100萬(wàn)，超過(guò)艾滋病、結(jié)核、交通事故以及自殺死亡人數(shù)的.總和，占全部死亡人數(shù)的12%。如不采取控制措施，預(yù)計(jì)到20xx年，該比例將上升至33%，死亡人數(shù)將達(dá)到200萬(wàn)，其中有一半人將在35歲至64歲間死亡。

　　雖然煙草業(yè)一直聲稱這個(gè)行業(yè)能夠帶來(lái)就業(yè)和稅收，對(duì)世界經(jīng)濟(jì)有很大貢獻(xiàn)，但根據(jù)世界衛(wèi)生組織提供的數(shù)據(jù)，煙草業(yè)對(duì)經(jīng)濟(jì)的貢獻(xiàn)遠(yuǎn)遠(yuǎn)不夠抵消它對(duì)家庭開(kāi)支、公共健康、環(huán)境和國(guó)民經(jīng)濟(jì)等所造成的損失。因此，世界衛(wèi)生組織將煙草流行作為全球最嚴(yán)重的公共衛(wèi)生問(wèn)題列入重點(diǎn)控制領(lǐng)域。20xx年5月，在日內(nèi)瓦舉行的世界衛(wèi)生大會(huì)上，世界衛(wèi)生組織192個(gè)成員國(guó)一致通過(guò)了第一個(gè)限制煙草的全球性條約——《煙草控制框架公約》，為在全球控制煙草危害，共同維護(hù)人類健康提供了法律框架。

　　控制煙草危害是一個(gè)具有長(zhǎng)期性、艱巨性和復(fù)雜性的公共衛(wèi)生問(wèn)題。因此，世界衛(wèi)生組織提出“創(chuàng)建無(wú)煙環(huán)境”，也是在告訴公眾，吸煙和被動(dòng)吸煙是人類健康所面臨的最大的但又是可以預(yù)防的危險(xiǎn)因素，公眾都有索取享有沒(méi)有煙草煙霧污染的清潔空氣的權(quán)利。只有“創(chuàng)建并享有100%無(wú)煙環(huán)境”，才能更好地保護(hù)人們免受煙草煙霧的危害。20xx年2月發(fā)布的《世界衛(wèi)生組織全球煙草流行報(bào)告》顯示，煙草是人類健康所面臨的最大且又可以預(yù)防的危險(xiǎn)因素，也是按其生產(chǎn)說(shuō)明使用卻導(dǎo)致高達(dá)50%吸食者死亡的唯一消費(fèi)品。20世紀(jì)煙草流行導(dǎo)致全球1億人死亡，如果各國(guó)政府不采取有力措施，這個(gè)數(shù)字將在21世紀(jì)變成10億，而且80%發(fā)生在發(fā)展中國(guó)家。全世界只有5%的人生活在完全禁止煙草廣告、促銷和贊助的國(guó)家，10億青少年中的85%生活在發(fā)展中國(guó)家。煙草業(yè)的廣告和促銷活動(dòng)，能誘惑青少年吸煙。青少年一旦嘗試了煙草這一高度成癮的產(chǎn)品，很容易造成終身煙草依賴。廣泛禁止煙草廣告和促銷，杜絕煙草行業(yè)對(duì)任何賽事或活動(dòng)的贊助，是保護(hù)青少年不受煙草危害的最有效途徑之一。

　　中國(guó)有3億多人吸煙，約占全球吸煙總?cè)藬?shù)的三分之一。20xx年的調(diào)查報(bào)告顯示，我國(guó)15歲以上男女學(xué)生的現(xiàn)在吸煙率分別為22。4%和3。9%。20xx年，男性教師吸煙率高達(dá)48。4%，既給兒童青少年造成了不良影響，又為學(xué)校控?zé)煿ぷ髟黾恿穗y度。健康是人全面發(fā)展的基礎(chǔ)，關(guān)系千家萬(wàn)戶的幸福。兒童、青少年是國(guó)家的未來(lái)，為進(jìn)一步做好控?zé)熉募s工作，提高全社會(huì)對(duì)吸煙危害的認(rèn)識(shí)，保護(hù)未成年人。

吸煙的危害作文4

　　這幾天，每打開(kāi)電視便能看見(jiàn)“吸煙危害健康”這個(gè)宣傳廣告。因?yàn)檫^(guò)幾天就是5月31日了，是世界衛(wèi)生組織發(fā)起的第十七個(gè)“世界無(wú)煙日”了�？吹搅诉@則廣告，我不禁在想：吸煙在當(dāng)今社會(huì)是一個(gè)極為普遍的現(xiàn)象，從年邁的爺爺奶奶，到十幾歲的青少年，他們都在不斷地吸食著這種“慢性自殺”的毒藥，人們都明白一個(gè)道理――吸煙有害健康，但真正了解吸煙危害的人卻寥寥無(wú)幾。

　　不知你是否注意到，在每盒香煙包裝盒上都有這樣幾個(gè)字：吸煙有害健康。吸煙有害健康，這句話應(yīng)該就像“喝臟水有害健康”一樣易于理解，吸煙能得氣管炎、心臟病、肺癌、胃病等多種疾病。醒眼不但污染環(huán)境，而且對(duì)青少年的生長(zhǎng)發(fā)育造成危害。

　　在這里，我想起了貧苦農(nóng)民出身的齊白石，在年輕學(xué)藝時(shí)也曾染上過(guò)吸煙的嗜好。后來(lái)朋友規(guī)勸他戒煙，為了健康和事業(yè)，他毅然與煙一刀兩斷，幾十年堅(jiān)持學(xué)習(xí)，堅(jiān)持作畫(huà)，“不教一日閑過(guò)”，年過(guò)九旬仍精神閃鑠，后來(lái)終于成為我國(guó)一名杰出的'畫(huà)家。

　　可是，我又想起了我的爸爸，我的爸爸是一級(jí)的“香煙迷“。記得小時(shí)候，我常跟著爸爸上學(xué)，每當(dāng)爸爸有空，他總會(huì)摸出隨身帶著的香煙吸上一支，干癟的嘴巴，有滋有味地吸著，然后咳嗽著從鼻孔里呼出煙來(lái)。爸爸的神情悠然自得，將最后一口煙噴給坐在旁邊呆看著的我�；鹄钡臒熚侗阒便@我的鼻子，我咳嗽，爸爸也咳嗽。

　　后來(lái)，當(dāng)我得知，爸爸咳嗽是因?yàn)殚L(zhǎng)期吸煙所致；當(dāng)我得知，煙草中含有大量尼古丁會(huì)危及生命是，我驚慌地把這些告訴爸爸。爸爸知識(shí)笑一笑地看看我，有默不作聲地從煙袋中摸出香煙塞進(jìn)嘴里，于是，咳嗽聲有響起……我知道，爸爸是不可能戒煙的，我很難過(guò)。

　　人們哪，該清醒了！不要再做花錢害自己的人了！

　　健康――永恒的時(shí)尚，吸煙有害健康。我希望全世界的人都不要吸煙，我們小學(xué)生要組織起來(lái)，向人們宣傳吸煙的危害，教育人們要保護(hù)自己的生存環(huán)境，讓我們共同努力把世界變成一個(gè)沒(méi)有污染、環(huán)境清新的世界吧！

吸煙的危害作文8

　　煙是一個(gè)殺人不見(jiàn)血的東西，中間包含著許多的壞東西，如：煙草主要是由碳水化合物（占40%~50%）羧酸、色素、萜烯類物質(zhì)、鏈烷烴、類脂物質(zhì)等組成，同時(shí)還有一些生長(zhǎng)過(guò)程中必需的營(yíng)養(yǎng)物（如硝酸鹽等）以及某些污染物（如農(nóng)藥、重要金屬元素等），吸煙的危害作文。煙草與別的植物不同這點(diǎn)是所含的萜烯類物質(zhì)比較豐富，即通常所說(shuō)的“蠟質(zhì)”或“尼古丁”。

　　吸煙者吸入香煙過(guò)程，是香煙在不完全燃燒過(guò)程中發(fā)生一系列的熱分解與熱合成的化學(xué)反應(yīng)，形成大量新的物質(zhì)，其化學(xué)成分很復(fù)雜，從煙霧中分離出有害成分達(dá)3000余種，其中主要有毒物質(zhì)為尼古�。�煙堿）、煙焦油、一氧化碳、氫氰酸、氨及芳香化合物等一系列有毒物質(zhì)。在煙草中原有的蛋白質(zhì)、碳水化合物、維生素、氨基酸等人體需要的'有益物質(zhì)，如果把它作食用那是有益的，但是把它作為香煙，經(jīng)過(guò)燃燒而釋放出煙霧灰塵等，也都變成有害物質(zhì)。煙草點(diǎn)燃的煙霧由兩部分組成，其中氣體部分，占據(jù)92%，包括多量的氧和氮無(wú)害氣體和一定量的一氧化碳及微量的致癌、促癌、纖毛毒物質(zhì)，粒相部分占8%，主要為尼古丁和煙焦油。同學(xué)們，看完這些后你們會(huì)有什么樣的感想呢？一定是被煙的危害嚇到了。不錯(cuò)，煙是個(gè)壞東西，有的人吸上癮后就再也戒不掉了。所以，我們必須積極抵制吸煙，幫助那些吸煙的人離開(kāi)陰影。

吸煙的危害作文9

　　創(chuàng)無(wú)煙環(huán)境，過(guò)健康美好的生活——是我們每個(gè)人的理想。“吸煙有害健康”在這個(gè)世紀(jì)流傳廣泛，大家都知道吸煙對(duì)我們的健康有著極大的傷害。我想，同學(xué)們的爸爸大多有吸煙這個(gè)壞習(xí)慣吧。同學(xué)們可能都想脫離這個(gè)云霧繚繞的環(huán)境吧，可我們不但沒(méi)有脫離，也許還會(huì)越陷越深哪！所以，同學(xué)們都應(yīng)該奉勸親人，遠(yuǎn)離危害！

　　我們也常聽(tīng)人說(shuō)“飯后一支煙，快樂(lè)像神仙”，可事實(shí)并非如此。吸煙的壞處就像繁星點(diǎn)點(diǎn)，數(shù)也數(shù)不完，何況很多人都愛(ài)抽煙呢。煙草里有三種危險(xiǎn)化學(xué)物質(zhì)：焦油，尼古丁和一氧化碳。焦油是由好幾種物質(zhì)混合成的物質(zhì)，在肺中會(huì)濃縮成一種粘性物質(zhì)；尼古丁是一種會(huì)使人成癮的藥物，由肺部吸收，主要是對(duì)神經(jīng)系統(tǒng)發(fā)生作用；一氧化碳能減低紅血球?qū)⒀踺斔偷饺�身去的能力。其�?shí)煙也是一種，只是沒(méi)有那么劇烈，國(guó)家沒(méi)有禁止而已。敬愛(ài)的叔叔阿姨們，你們?cè)诔闊煏r(shí)想過(guò)后果么？吸煙不僅對(duì)自己的身體造成威脅，還對(duì)你身邊那些被動(dòng)吸煙的人也造成了極大的危害。這一根根煙頭，就像一只只毒藥，徐徐的向我們逼近，給我們的生活和工作也帶來(lái)了極大的威脅。假如你每天都處在煙霧中，你的身體會(huì)越來(lái)越虛弱，病魔會(huì)時(shí)時(shí)侵害你，甚至危及你的'生命�？膳碌氖牵阂粋�(gè)每天吸15到20支香煙的人，極易患肺癌、口腔癌或喉癌致死的機(jī)率，要比不吸煙的人大14倍；極易患食道癌致死的機(jī)率比不吸煙的人大4倍；比死于膀胱癌的機(jī)率要大兩倍；死于心臟病的機(jī)率也要大兩倍。吸香煙是導(dǎo)致慢性支氣管炎和肺氣腫的主要原因，而慢性肺部疾病本身，也增加了得肺炎及心臟病的危險(xiǎn)，并且吸煙也增加了高血壓的危險(xiǎn)。聽(tīng)了這一句句驚心動(dòng)魄的描述，你感覺(jué)到危險(xiǎn)正向你慢慢的逼近了嗎？你體會(huì)到自己那飽受痛苦的呻吟了么？想一想，吸煙除了帶來(lái)危害，它能給予你什么？給予你家人為了你抽煙而鬧得家庭不和么？所以奉勸那些有煙癮的朋友們好好的想一想吸煙的危害，及時(shí)戒煙吧！

　　為了防止越來(lái)越多的人吸煙，僅僅靠一個(gè)人的力量是不夠的，我們大家應(yīng)該團(tuán)結(jié)起來(lái)，去掉這一大不良習(xí)慣和危害。

　　現(xiàn)在，我鄭重的呼吁大家，放下手中的煙吧！讓我們一起和家人幸福的生活，一起創(chuàng)造美好的未來(lái)吧！
