I think at first all of the students they just want to know how it taste so they keep on trying or by their friends invited. However some were not addicted to it, some were. The most common reason of those is they feel used to it such as after meals they always smoke or even have nothing to do. Obviously, the university can't controll the students' behave, but yes the university should not allowed them to smoke in public area, they just might prepare some area or provide a smoking room for them like MBK. By my advise, I think at least other students who don't smoke they won't be affected and get annoying because of some others. In our age, we don't like to do by the adults' advises just follow our mind so it's really difficult to manage all this.
