'Walking junkie' Chambers reveals full extent of his drug use

The full extent of Dwain Chambers' drug use has become apparent as the disgraced sprinter prepares to release his autobiography. Chambers failed an out-of-competition drug test in 2003, subsequently admitting to the use of performance enhancing substances for which he was banned from athletics for two years and from the Olympic Games for life.

The timing of the revelations in his autobiography 'Race Against Me: My Story', the serialisation of which begins today in the Daily Mail, is sure to cause emormous distress in the athletics world as Chambers admits just how comprehensive his drug use was. Describing a moment where he arrived at customs at a US airport, Chambers reveals how he feared he was about to be caught.

"Checking in at Miami International Airport I noticed the couple in front of me were having their hand luggage searched. Shit, what if they search my bag?

"There were enough drugs in there to kill an elephant and I didn't have a clue whether they were legal or not. I was a walking junkie. I had tubes of stuff that were known only to me as 'The Clear' and 'The Cream' along with a few bottles of EPO and HGH, which were in ice packs as they needed to be kept cool.

"They had been labelled by Victor Conte, the founder and president of Balco, the man who put me on his training programme, as 'flaxseed oil' and 'joint cream'.

Chambers, whose return to athletics has been dogged by controversy, reveals how he was introduced to the world of performance enhancing drugs by his Ukrainian
