text: I believe that people do drugs because they can't face reality.  alot of young people do it because it was introduced to them by a friend. However, a strong teen, can refuse it I believe that alot of it is what the parents instill in them. however, when it comes to an adult, the only reason I can possibly think of is stupidity. I'm sure that alot of them have personal problems,  it is a way to destroy your body, family, children, and everything areound you. so when someone does drugs they affect everyone, not just their selves.
