smoking can affect other people. some people are sensitive to the smell of smoke, and even if you aren't smoking in front of them, the smell will remain on their clothes, ****** others uncomfortable. especially in an enclosed classroom, smoking can affect one's emotion negatively and also spoil the whole studying ambience.
