Michael Phelps blows dope and career?

THIS is the astonishing picture which could destroy the career of the greatest competitor in Olympic history.

In our exclusive photo Michael Phelps, who won a record EIGHT gold medals for swimming at the Beijing games last summer, draws from a bong.

The glass pipes are generally used to smoke cannabis.

And after sporting chiefs announced laws which mean four-year bans for drug-taking, Phelps' dreams of adding to his overall 14 gold medal tally at the 2012 games in London could already be OVER.

Those dreams seemed the last thing on his mind when he puffed from the bong during two days of partying with students last November, a quiet time in the swimming calendar when athletes would not expect to get tested for drugs.

One party-goer who witnessed the star's behaviour told the News of the World: "He was out of control from the moment he got there.

"If he continues to party like that I'd be amazed if he ever won any more medals again."

Phelps' aides went into a panic over our story and offered us a raft of extraordinary incentives not to run the bong picture.

It was on November 6, weeks after his Beijing triumph, that 23-year-old Phelps surprised students at the University Of South Carolina in Columbia by showing up unannounced at a house party.

He was visiting Jordan Matthews, a girl he was secretly seeing who was a student there.

Our source revealed: "Michael came to visit Jordan but ended up just getting wasted every night.

"He arrived with a group of girls hanging all over him. Jaws hit the floor when he walked in. You don't get many celebrities in Columbia, so when Phelps comes to your party it's a very big deal.
