I dont think the majority of athletes use these drugs, that's a little presumptuous. But, it is safe to say that athletes are getting away with it a lot and that should not be the case. I think we'd have to put ourselves in the shoes of those who they compete with. If you were the biker, or swimmer, baseball player, or whatever... And you lost only to find out that the winner was using PED's I think you'd have a new-found levelp of disappointment. It undermines the integrity and efforts of others.
But I agree that you are innocent untill proven guilty, but his withdrawal leaves me perplexed, lol.
