I believe there are many people already know about why they should not smoking but here I would like to share my opinion of why you should stop smoking. Perhaps the most basic question is whether smoking has any benefits for us. This is actually a pro and con question because there are some people who can share the benefits of smoking.

Here are some of the facts that I have gathered from many sources about the benefit of smoking:

• decreases appetite
• reduce the risk of ulcerative colitis, breast cancer and allergic asthma, Parkinson's disease or Alzheimer's disease
• a self-medication for persons suffering from schizophrenia
• improves human information processing
• improves motor performance 
• smokers have less plaque, gingival inflammation and tooth mobility
• smokers have lower incidence of postoperative deep vein thrombosis
• lower Hypertension (high blood pressure) and postpartum hemorrhage
• etc

The major health risks of smoking are heart attack, asthma, and lung cancer. Those health diseases are more dangerous than the benefit of smoking because they would bring the patient to death. I believe that we can survive without smoking, and we don't even need to smoke.

Once I met a very poor woman who said that she always live in debt not only because she and her husband cannot earn much money but also because her husband spends 20-25% of their total income every month only for smoking. It's unwise when you need to get a loan just because you spend your money for the things which does not give you any benefit.

Smoking will tie you up and you will hardly get rid of the smoking habit because nicotine in the tobacco which you inhale from smoking is a drug that causes addiction. Only 2.5 percent of smokers successfully quit each year and if only you stop smoking before or during middle age (age 35 to 50), you will avoid about 90 percent of the lung cancer risk.

After you have read some of the facts about smoking, here are some points which are the reasons why you should quit smoking.

• Smoking poisons your body
• Smoking poisons people around you
• Smoking spends some of your money

Those are the three major reasons which tell us that smoking does not do any good at all. It has negative effects and only cigarette companies take profit from smoking. By smoking, you would just helping the cigarette companies of getting rich. Smokers are only a commodity of those companies.
