Andre Agassi, 1997
He was the undisputed star of world tennis for years, but tennis was rocked in 2009 when Andre Agassi admitted to using methamphetamine just two years after claiming the world number one ranking in 1995.
Making the shock claims in his autobiography Open, Andre detailed his first experience of taking crystal meth in 1997, when he was suffering poor form and preparing to marry actress Brooke Shields.
“There is a moment of regret, followed by vast sadness,” he wrote. “Then comes a tidal wave of euphoria that sweeps away every negative thought in my head.”
Later that same year, the drug was picked up in his system following a routine test.
Andre admitted lying in a letter to tennis’ governing body, where he claimed to have accidentally injected his assistant’s soda which was spiked with the drug.
He avoided any ban and vowed never to take the drug again.
Crystal meth was Andre’s downfall in 1997.
