From the BBC
The Association of Tennis Professionals (ATP) said it could not comment because it withdrew a doping case against him.
An ATP spokesman said it commented on the results of drugs tests only when a violation had occurred.
"Under the tennis anti-doping programme it is, and has always been, an independent panel that makes a decision on whether a doping violation has been found," he stated.
"The ATP has always followed this rule and no executive at the ATP has therefore had the authority or ability to decide the outcome of an anti-doping matter."
BBC Radio 5 live's tennis correspondent Jonathan Overend feels Agassi's legacy could be ruined by the revelations and will also damage tennis's reputation.
"This is sure to severely tarnish the reputation of one of the great champions," said Overend.
"I think it will have underlying implications for the sport in terms of the suspicion about some of the athletes and whether or not they are on drugs.
"The fact that Agassi lied and the authorities believed him has enormous repercussions. How many other cases may there have been like this?"
From ITF President Francesco Ricci Bitti
Please find below a statement from ITF President Francesco Ricci Bitti concerning the statements made by Andre Agassi:
“The ITF is surprised and disappointed by the remarks made by Andre Agassi in his biography admitting substance abuse in 1997. Such comments in no way reflect the fact that the Tennis Anti-Doping Programme is currently regarded as one of the most rigorous and comprehensive anti-doping programmes in sport. The events in question occurred before the World Anti-Doping Agency (WADA) was founded in 1999 and during the formative years of anti-doping in tennis when the programme was managed by individual governing bodies. The ITF first signed the WADA Code in 2004, and the Tennis Anti-Doping Programme undergoes constant review and improvement. In 2006, the ITF assumed responsibility for administration of the anti-doping programme on behalf of the ATP and then, in 2007, also on behalf of the Sony Ericsson WTA Tour. The ITF, Grand Slams, ATP and Sony Ericsson WTA Tour are now unified in their efforts to keep tennis free of drug use, and this should not be overshadowed by an incident that took place over 12 years ago. The statements by Mr. Agassi do, however, provide confirmation that a tough Anti-Doping Programme is needed.”
Following Andre Agassi's revelation that he was let off by the ATP after testing positive for crystal meth in 1997, WADA chief John Fahey says he expects the ATP "to shed light on this allegation"
So far nothing from the Grand Poobah's of American tennis journalism.
