According to a report by ESPN.com, eight-time Grand Slam champion Andre Agassi admits to using crystal meth in 1997 in his upcoming autobiography. He also admits that he lied to tennis authorities when he failed a drug test, saying that he “unwittingly” took the substance.

According to an excerpt of the autobiography published Wednesday in The Times of London, 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.

“I feel ashamed, of course. I promise myself that this lie is the end of it.”

According to the Times of London, Agassi writes in his book that “Slim” was the person who introduced him to crystal meth, dumping a small pile of powder on the coffee table.

“I snort some. I ease back on the couch and consider the Rubicon I’ve just crossed,” Agassi writes.

“There is a moment of regret, followed by vast sadness. Then comes a tidal wave of euphoria that sweeps away every negative thought in my head. I’ve never felt so alive, so hopeful — and I’ve never felt such energy.”

“I’m seized by a desperate desire to clean. I go tearing around my house, cleaning it from top to bottom. I dust the furniture. I scour the tub. I make the beds.”

I always find it interesting how athletes and celebrities are so willing at times to share the skeletons in their closet in order to sell their books. Here’s a guy that is one of the more popular stars to every play tennis and he outs himself as a crystal meth user in order to drum up some sales. It’s amazing, although not entirely dumb if you want people to flock to the stores to buy your book.
