TEENAGE SMOKING

on Saturday, September 28, 2013

     One of the reason why teenagers smoke is to try to make themselves look older.Some way think that smoking or chewing tobacco makes them more hip or good looking,like a movie star or a famous baseball player.Another reason is to seem cool in front of their friends.And some say that smoking helps them to relax.In actual fact,smoking actually raises their blood pressure and makes their heart beat faster.
    Others may think it is all right to smoke because people in their family do.Sometimes it may seem like everyone is using tobacco,so it cannot be that bad.The sad fact is they do not realise how poisonous and dangerous tobacco is.
     When people try smoking for the first time,they often cough a lot and feel pain or a burning sensation in their throat and lungs.This is because the body is being smart.The lungs are trying to protect the smokers and telling them to keep the lungs smoke-free.However,this is often not heeded.And so the teenagers get stuck to the cigarette.
