A few decades ago, a new item called cigarettes was advertised as a kind of new entertainment product. Once it was in the market, people enjoyed them without awareness of their addiction. It was unknown how damageful it was back then. Through the years, scientists have done some research about tobacco and its harm to living things. Therefore, many people believe that this drug should be banned from the shops. In my opinion, I disagree with that thought because it is almost impossible to be forbidden.
