Smoking

Smoking is one of the biggest problems of human today. As everybody knows, smoking is extremely harmful for people's health.In spite of this fact,there are many people who are destroying their bodies by smoking for a little satisfaction.What is worse; the smoking habit starts at very early ages. I have many friends who have started smoking at primary school. Even if they want to give up, it is very difficult,because cigarette is addictive. Moreover, a smoker has to spend a lot of money on cigarette, so smoking is also an economical disadvantage.
