You now skip a few years and at secondary school thate means exams.  Hopefully all has gone well. Some of your friends have begun to smoke cigarettes which they only tried but now are sneaking them outside the school. Teachers only go so far and your "friends" suggest it is easy to try. There are several of them and they are very convincing. Some of them say you have to suck in with a deep breath. Go on it won't kill you.
