Agassi admits using crystal meth

NEW YORK: Andre Agassi's upcoming autobiography contains an admission that he used crystal meth in 1997 and lied to tennis authorities when he failed a drug test - a result that was thrown out after he said he "unwittingly" took the substance.

According to an excerpt of the autobiography posted on The Times of London website on Tuesday, the eight-time Grand Slam champion writes that he sent a letter to the ATP tour to explain the positive test, saying he accidentally drank from a soda spiked with meth by his assistant "Slim".

"Then I come to the central lie of the letter," Agassi writes. "I say that recently I drank accidentally from one of Slim's spiked sodas, unwittingly ingesting his drugs. I ask for understanding and leniency and hastily sign it: Sincerely.
