Agassi has admitted in his autobiography that he took crystal meth and tested positive for it!!! He never recieved a ban and It seem that the ATP brushed it under the carpet along with other drug scandals such as "The Nandrolone Seven". in 2003, seven players tested positive for the banned steroid They were never named because, like Agassi, they were all acquitted. and Richard Gasquet case during the summer. After a positive cocaine test, a tribunal basically believed the Frenchman's explanation that the banned substance came from a lingering kiss with a Miami waitress. He received a reduced two-month ban which effectively cleared him to return to action straight away. Cycling has a bad rep for drugs in its sport but they seem to be trying to eraditcate it but tennis seems to be going the other way http://www.timesonline.co.uk/tol/sport/tennis/article6892979.ece
