I really don't know how prevalent drug use is in sport. But I am sure that for every one caught there are a multitude of others undetected. What do you think or know? I think we can say with out any doubt that tour de france cyclists define cheating as taking more than your medical people prescribe, but is this the position of all athletes in all sports. I heard recently that young people showing talent may need to take drugs one day to get them the edge that they need to compete on the world stage. Has drug use become like speeding, everyone does it but you don't get a ticket unless you get caught significantly over the limit.
