Smoking,killing or helping? Nowadays,cigarette is always thought as one of the most harmful killers for peoples’ health.But,has anyone think about:such a kind of bad thing is also necessary for us.Though nearly all of us hate it too much,nobody can deny that human needs nicotine. So,what people worry about most is teenagers.They are becoming a bigger part of the smoke. Firstly,we should understand,for this question,we have no absolute answer. So,before we get the answer,I wonder why teenagers get interested to nicotine?For fun,think it cool or only learn smoking like their father.If they smoke for these reasons,they are only killing their time even life.Well,a teenager knows why teenagers do that,so on the other hand,pressure form school should be guilty. Parents always think about this subjectively,because they will never agree their dear children waste their life time just like his or her father.On the other hand, do children want to break their heart.During my high school study life,I saw many classmates,before our month-test,their are so nervous that they can not even keep relaxing much less having a good sleep.Having no choice,they begin to learn smoking which can do give them some relax. Others find stay up late at night so difficult,we have homework to do,but,how can you finish your homework or do some review when you can’t help sleeping.Finally they found nicotine more useful than tea or coffee.They sure understand what they drag will make their life shorter,compare to leaving the homework,they make a decision. Like the example above,we can easily got that not every teenager start smoking blindly.They have their own reasons,they have their own difficulties.Other people especially teenagers’ parents should give some patience. And there is no doubt that whatever your reasons are,people should try their best to smoke less. For teenagers,no smoking can sure be better,but once you decide to start smoking,keep in mind:control yourself,let cigarettes be your helper rather than a killer. 本文来源：https://www.wddqw.com/doc/3ddb459bc1c708a1294a440c.html
