The real discussion is not about the potency of the drug. The athlete, especially one at professional level, knows that they are able to declare any medically necessary drug and gain a waiver from future positive tests. Filling in her drug declaration at a meet is no different than filling in your entry form. When I ran, if I didn't do that I never got into the event. She can not claim ignorance, this isn't the first time she ever raced at this level. As for the 200m being clean, she may have already realised what was coming down.
I think she is a great runner, and while I am not a fan of Dick Pound's vitriol, I see Kellie White, has won the WCs despite being an asthmatic narcoleptic. That's an inspiration for anyone. Wink wink.
