Former steroid users that have completed their bans are allowed to compete at Olympics

The runner Dwain Chambers, who successfully served his 2-year ban for application of anabolic steroids, was named the representative of Great Britain in the 2012 London Olympics.
Chambers worries about the way to represent the native country. As for the British Olympic Association (BOA), they don’t want to see him taking part in the Olympic Games. Certain former British Olympians don’t support the consumer of steroids as well.
Dwain Chambers administered the steroid tetrahydrogestrinone (THG) introduced by Patrick Arnold. After Don Catlin developed a method which could detect THG, Chambers tested positive for this steroid. It was on November 7, 2003.
Undoubtedly, intake of the steroid spoiled his reputation. When he tried to return to professional sports, the BOA decided to change the laws in order to prevent appearing of the sprinter in the 2012 London Olympics. The BOA has elaborated the rules that ban steroid users from Olympics for the whole life.
Elaborating this rule, the BOA violated the doping code of the World Anti-Doping Agency (WADA). This factor resulted in numerous disputes and news.
The case was even presented in the Court of Arbitration for Sports. Loyd Moynihan, the chairman of the BOA, put essential efforts in order to prevent appearing of Dwain Chambers or other consumers of steroids at Olympics. Sebastian Coe and Daley Thompson, former Olympians, loudly supported efforts of the BOA.
 Daley Thompson stated that Britain should not compromise. He noted that Britain should not listen to the rest of the world that don’t desire to have high standards in sports. The Court of Arbitration for Sports acted on behalf of the WADA. Chambers was allowed to be the representative of Britain at the 2012 Summer Olympics. This case turned out to be an open door for other athletes that have served their suspensions to participate in Olympics.
The cyclist David Millar and the shot-putter Carl Myerscough that have served their bans for intake of steroids will compete at the 2012 Olympics as well.
Despites wasting much time to prevent appearing of steroid users at Olympics, the BOA finally stated that not only Chambers but also Millar, Myerscough or any other sportsperson that has served a suspension successfully may compete at Olympic Games. Andy Hunt, the CEO of the BOA, has confirmed that any athlete is treated the same way.
