Mike Tyson: I was high for many big fights

KNOCKOUT: In this Nov. 22, 1986, file photo, Mike Tyson, right, delivers a powerful blow to Trevor Berbick in the second round in Las Vegas. At one time he was the baddest man on the planet, a heavyweight champion who terrorized anyone who got in his way, inside the ring or out. More recently he's unburdened himself as perhaps the most tortured soul on earth, with a one-man show on Broadway that Spike Lee has turned into an HBO special airing Nov. 16. Now he's got a new autobiography that might be the most soul baring book of its genre ever written. The title is "Undisputed Truth," and the truth is that Mike Tyson is one messed up dude.

Mike Tyson has stunned fans by revealing he was high on drugs as he stepped into the ring for many of his major fights in his new autobiography.

The boxing champ-turned-entertainer’s memoirs, “Undisputed Truth,” were released this week, and one chapter is already making the headlines.

Tyson explains he went to extremes to avoid testing positive for illegal drugs, revealing he used “clean urine” and a “fake penis” to make sure he was passed to fight.

And he only got caught out once – when he was tested before he had a chance to install his “whizzer” prior to his 2000 fight with Andrew Golota.

Tyson was fined $200,000 when he tested positive for marijuana.

The fighter blames cocaine for the brawl he had with Lennox Lewis prior to a big bout in 2002, during which he bit his opponent’s legs.

He says, “I lost my mind. I looked over at him (Lewis) and wanted to hit the (expletive).”

Tyson opened up about the extent of his ongoing alcohol problems earlier this year, when he tearfully revealed he was “a vicious alcoholic on the verge of dying” during a press conference to launch his new promotions company.
