I think that a lot of men who take steroids aren't fully aware of how badly damaged their bodies will be in the future. There is a fascinating documentary on steroid use called "Fat, Sick and Nearly Dead." It was very eye opening about what happens after you abuse steroids.
It's sad that most people that abuse drugs are so desperate to escape the present, that don't think about their futures. Life changes drastically as you mature and get more world experience.
