Disadvantages of smoking

Smokers are more likely to get cancer than non-smorkers. This is particularly true of lung cancer, throat cancer and mouth cancer which hardly effect non-smokers.

These are the fact about smoking :
   
-Ninety per cent of lung cancer cases are due to smoking,
-one in ten moderate smokers and almost one in five heavy smoker who smoke more than ten cigarettes a day    will die of lung cancer.
-The more cigarettes you smoke in a day and the longest you have smoked, the higher you get risk of lung cancer. Similarly, the risk rises the deeper you inhale and earlier in life you started smoking.
-for ex-smoker, it takes approximately fifteen years before the risk of lung cancer drops to the same as that of non-smokers.
- If you smoke, the risk of contracting mouth cancer is four times in many areas of the mouth,most common,on or underneath the tongue.
