1. i think the therapy that was supposed to have saved his life reacted badly and that is why he died. if you're asking if his disease is a result of steroid use, no one knows. he used steroids and got sick but no one knows if there is a cause-effect link.

2. i disagree with steroid use but there are other issues here. if the olympics can't control steroid use do you think pro sports promotions can? once they can control them, will they? look at american football. they can greatly reduce the knee injuries just by passing a rule on footwear. this will never happen because it will reduce the quality (speed) of the game. lebanner is stronger and faster than before. do you think anyone wants to see him lose power or speed?
