Drug cheats is unfair. Hence the word cheat. PLus what about all the athletes that train harder than these steroid junkies.
Just because one takes steroids doesn't mean they train any less hard than someone off them. Case in point, pro bodybuilders. Many of the pros take steroids, but they still train harder than a lot of the other gym junkies. I don't really condone or reject steroid use, but it's a pretty big misconception that steroids are a magical drug that instantly make you better... you still have to work hard to make them useful/worthwhile.
