How does positive and negative peer pressure influence tobbaco use among teens?

If a friend of yours offers you a cigarette, just so that you can try it and find out what it is like, there is a certain pressure to accept the offer because if you don't, it will seem that you are afraid of smoking, and teenagers do not want to be thought to be cowardly. It is also widely thought that it is a good idea to find out about things for yourself rather than taking other people's Word, so even though everyone has been told that smoking is a bad thing, you may want to find out for yourself. The only problem with this idea is that in the process of finding out, you may wind up becoming addicted to nicotine.
