Crystal meth is not a performance enhancing drug. Agassi was taking it in 1997 which were not, to put it mildly, his glory days. He started the year ranked no. 8 and ended it ranked no. 110.
But the tennis doping body "wants answers".
People also got very upset that Marina Hingis took cocain.
Remind me again why nobody cared that Obama took cocain? If we get all upset about a tennis player taking drugs in the distant past, why don't we care about the president taking drugs in the distant past.
