What was dwain chambers banned for

Chambers tested positive in an out-of-competition screening Aug. He maintained he never knowingly took a banned substance. Scientists say THG is related to the banned steroid gestrinone. Many Olympic officials are gathered in Athens for a weeklong series of meetings related to the Summer Games in August. Terry Madden, the head of the U. Confirming their verdict on the athlete who was set to be one of Britain's chief standardbearers at this year's Athens Olympics, UK Athletics said in a statement: "Dwain Chambers has been found guilty of doping from a positive test for THG.

Chambers, who failed the out-of-competition test on August 1 last year, had argued he unknowingly took THG as a dietary supplement supplied by Victor Conte's San Francisco laboratory. Last week his former coach Remi Korchemny was indicted by a federal grand jury in the United States on charges relating to distributing steroids and growth hormones to athletes. Tuesday's guilty verdict was handed down only after UK Athletics had examined complex scientific evidence at last week's hearing to determine whether THG, which does not yet figure on the International Association of Athletics Federations' list of prohibited drugs, was actually a banned substance or not.

UK Athletics said that they had proved that the relationship existed and that THG was related to gestrinone. Chambers said he was applying a masking agent known as The Cream when the tester arrived, which allowed him to pass the test despite being at the height of his drug use.

Chambers also reveals just how easy it is for drug cheats to beat the system and avoid the testers who arrive at athletes' homes unannounced for out-of-competition testing.

Britain's former drugs cheats can compete at London after a court overturned the British Olympic Association's policy of lifetime bans.

The BOA had been locked into a lengthy legal battle with Wada over what it said was its right to continue imposing lifetime Olympic bans on British athletes, even after they had served suspensions. But Cas has ruled the BOA must comply with Wada, paving the way for British athletes who were banned for life from Olympic competition to be eligible for selection after serving shorter bans. We will seek far-reaching reform, calling for tougher and more realistic sanctions; a minimum of four years including one Games.

The BOA argued that its requirement for athletes to have clean drugs records was part of its Olympic selection criteria and had nothing to do with extending violators' punishments - a view supported by a number of high-profile current British athletes and the International Olympic Committee IOC.
