吸烟的危害
吸烟不仅对吸烟者本人造成危害，“二手烟”还会对周围的人造成危害。烟草所含的有害成分有4000多种，大致可分为四类。1、一氧化碳：主要影响红细胞与氧的结合能力，使机体输氧功能降低。2、刺激性物质：主要有氨、苯等，可刺激咽、眼、鼻，刺激支气管粘膜下腺体，可导致急慢性气管炎，长期刺激可造成癌变。3、尼古丁（烟碱）：尼古丁最大的危害在于它的成瘾性，且作用极为迅速，吸烟者只需7.5秒就可以到达大脑。它是一种抗焦虑药物，大量吸入可引起抑制或麻痹作用。同时它可使末梢血管收缩，心跳加快、血压上升，促进血小板凝聚，导致动脉粥样硬化，诱发心血管疾病；4、致癌物质：有尼古丁、焦油、苯、亚硝胺、丙烯等烟雾中还含有较多的放射性元素，吸入以上物质后可损害机体组织细胞，破坏机体免疫力，为癌细胞生长创造环境。吸烟可增加肺癌、食管癌、胃癌、膀胱癌、鼻咽癌等癌症的发病率，还能使气管炎、咽喉炎、糖尿病、动脉硬化、高血压等疾病发病率大大增加，甚至可以造成猝死。吸入“二手烟”的造成的危害和直接抽烟的人没有区别，吸烟（包括被动吸烟即吸入二手烟）对儿童、青少年、女性的危害更大。有研究表明，30岁以前戒烟，肺癌风险减少90%，戒烟五年后，由吸烟所致的口腔和食管癌风险减少一半，心血管疾病的风险降低更为迅速。英国一项研究表明，吸烟者比不吸烟者平均早死亡10年，60、50、40或30岁戒烟，分别可赢得3、6、9或10年的预期寿命。为了您和您的家人、朋友的健康，劝各位抽烟的朋友早日戒烟吧。
The hazards of smoking
Smoking is not only harmful to the smokers themselves, "passive smoking" but also to others around them harm. Tobacco contains harmful ingredients are more than 4,000 can be divided into four categories. 1, carbon monoxide: The main impact of the binding capacity of red blood cells with oxygen to make the body function of reduced oxygen. 2, irritant substances: mainly ammonia, benzene, etc., can stimulate the pharynx, eyes, nose and stimulate the bronchial submucosal glands can lead to acute and chronic bronchitis, long-term stimulation can cause cancer. 3, nicotine (nicotine): Nicotine greatest harm is that it is addictive, and the role of the extremely rapid, smokers can be just 7.5 seconds to reach the brain. It is an anti-anxiety drugs, a large number of inhalation may cause inhibition or paralysis effect. At the same time it will enable the peripheral vasoconstriction, rapid heartbeat, increased blood pressure, promote platelet aggregation, leading to atherosclerosis, induced cardiovascular disease; 4, carcinogenic substances: There are nicotine, tar, benzene, nitrosamines, propylene and other smoke also contains more radioactive elements, inhalation, after the above substances can damage body cells, damages the body's immune system, create an environment for the growth of cancer cells. Smoking can increase the lung, esophagus, stomach, bladder cancer, the incidence of cancer and nasopharyngeal cancer, but also to make bronchitis, laryngitis, diabetes, arteriosclerosis, high blood pressure greatly increased the incidence of such diseases can even cause death . Inhalation of "second-hand smoke" in the damage and direct no distinction between those who smoke, smoking (including passive smoking, or passive smoking) on children, youth, women's more insidious. Studies have shown that quitting smoking before the age of 30, lung cancer risk reduced by 90%, to quit after five years of smoking caused by the oral and esophageal cancer risk reduced by half, reduce the risk of cardiovascular disease more rapidly. British study showed that smokers die earlier than non-smokers an average of 10 years, 60,50,40 or 30-year-old quit, respectively won the 3,6,9 or 10-year life expectancy. To you and your family, friends, health, advise you as soon as possible to quit smoking friends bar.

Smoking will aggravate cardiovascular disease, accelerated atherosclerosis and blood clots, leading to arrhythmia and even sudden death. Some scholars study found that smokers of sudden death caused by coronary heart disease than non-smokers for more than four times higher. Smoking can damage the nervous system, makes memory deterioration, premature aging. 吸烟会使心血管病加剧，加速动脉粥样硬化和生成血栓，导致心律不齐，甚至突然死亡。有的学者研究发现，吸烟者由冠心病引起的瘁死，要比不吸烟者高四倍以上。
吸烟会损害神经系统，使人记忆力衰退，过早衰老。
吸烟会损害呼吸系统，经常吸烟的人，长年咳嗽、咳痰，易患支气管炎、肺气肿、支气管扩张等呼吸道疾病。
吸烟者容易得胃溃疡，因为香烟烟雾中的烟碱，能破坏消化道中的酸碱平衡。 烟草中大约含有一千二百多种化合物，其中大部分对人体有毒，特别是尼古丁，危害尤大。一支香烟里的尼古丁，可以毒死一支老鼠，20支香烟里的尼古丁能够毒死一头牛。一个人如果每天抽20～25支香烟，就将吸入50～70 mg尼古丁，这些尼古丁足可以致人于死地，只是由于它们是逐步吸入的，再加上人体有一定的解毒能力，才幸免于难。
烟草中含有许多致癌物，另外还有许多促致癌物，以及能够降低机体排出异物能力的纤毛毒物质。这些毒物附在香烟烟雾的微小颗粒上，到达肺泡，并在那里沉积，彼此强化，结果又大大加强了致癌作用。每天吸烟10支以上的人，肺癌死亡率要比不吸烟者高两倍半。此外，吸烟还能引起喉癌、口腔癌、鼻咽癌、食道癌、胰腺癌、膀胱癌等。 有人说：“饭后一支烟，赛过活神仙。”因此有些人，特别是一些青年人经常陶醉于“吞云吐雾”之中。殊不知，就在他们悠悠自得的时候，烟草中的各种毒物便向他们展开了残酷的进攻。
据分析，烟草中大约含有一千二百多种化合物，其中大部分对人体有毒，特别是尼古丁，危害尤大。一支香烟里的尼古丁，可以毒死一支老鼠，20支香烟里的尼古丁能够毒死一头牛。一个人如果每天抽20~25支香烟，就将吸入50~70mg尼古丁，这些尼古丁足可以致人于死地，只是由于它们是逐步吸入的，再加上人体有一定的解毒能力，才幸免于难。

总之，吸烟对身体健康危害甚大。据世界卫生组织的一项报告，全世界每年至少有100万人由于吸烟而过早地死亡。报告中还提供了一些惊人数字：肺癌患者的90%以及各种癌症患者的1/3是吸烟引起的，75%的慢性支气管炎患者和25%的心脏病患者是由于吸烟所致。
吸烟不仅害己，也危害他人，强迫别人“被动吸烟”。事实上，凡吸烟可能引起的种种疾病，在被动吸烟者身上都有可能发生。 Smoking can damage the respiratory, heavy smokers, long cough, sputum, susceptible to bronchitis, emphysema, bronchiectasis and other respiratory diseases. Smokers susceptible to gastric ulcer, because the nicotine in cigarette smoke, can damage the digestive tract in the acid-base balance. Tobacco contains more than 1200 kinds compounds that about most of them toxic to humans, especially nicotine, harmful particularly great. One of the nicotine in cigarette smoke can poison a rat, 20 cigarettes, the nicotine can kill a cow. If a person 20 to 25 a day smoking cigarettes, it will be inhalation of 50 ~ 70 mg of nicotine, the nicotine is enough to kill, but because they are gradually inhaled, along with detoxifying the body have a certain ability to be spared was difficult. Tobacco contains many carcinogens, in addition to promoting a number of carcinogens, and the ability to reduce the body's ability to discharge foreign body cilia toxic substances. While these chemicals are attached to the cigarette smoke of tiny particles reach the alveoli, where deposition, mutually reinforcing, the result has greatly enhanced the carcinogenic effects. Smoking 10 cigarettes a day or more people, lung cancer mortality rate than non-smokers, twice and a half. In addition, smoking can cause throat cancer, oral cancer, nasopharyngeal cancer, esophageal cancer, pancreatic cancer, bladder cancer, and so on. Some say: "a cigarette after a meal is better than life." So some people, especially those frequented by young people revel in the "puff" at home. As everyone knows, just as they leisurely contentment, when tobacco was given to them in a variety of toxins carried out brutal attacks.

Smokers susceptible to gastric ulcer, because the nicotine in cigarette smoke, can damage the digestive tract in the acid-base balance. In short, the health hazards of smoking on great. According to a report by the World Health Organization, worldwide there are at least 1 million people each year due to smoking and premature deaths. The report also provides some startling figures: 90% of patients with lung cancer and a variety of cancer patients 1 / 3 is caused by smoking, 75% of chronic bronchitis patients and 25% of patients with heart disease is caused due to smoking. Smoking is not only sinful, but also endanger others, force others to "passive smoking." In fact, where smoking may cause various diseases, in the passive smokers who are likely to occur.
