CJ Ujah, who faced a four-year ban after testing positive for two prohibited drugs, has now been cleared of deliberately taking them

British sprinter CJ Ujah has been cleared of deliberately taking banned drugs before the Tokyo Olympics.The 100m sprinter won the 4x100m relay with Team GB Men last year. However after CJ tested positive for ostarine and S-23, the team were stripped of their medals. CJ also faced a four-year ban.Despite the previous punishment, the Athletics Integrity Unit have now reduced the sprinter's ban to 22 months after an investigation found that he had taken a contaminated supplement by mistake.He still has to face a ban due to World Anti-Doping Agency ruling that athletes are responsible for everything they put in their bodies.

The AUI said: "The AIU and Wada were satisfied that the sprinter's anti-doping rule violation was not intentional as a result of his ingestion of a contaminated supplement and the applicable two-year period of ineligibility was reduced by two months on account of how promptly he admitted the violation."

Head of the AIU Brett Clothier also warned athletes that they should be careful when taking supplements and that they should payattention to the rules and athlete education programmes. He said: "In this case, after a thorough examination of the facts, we were satisfied that Mr Ujah did indeed ingest a contaminated supplement, but he was unable to demonstrate that he was entitled to any reduction in the applicable period of ineligibility based on his level of fault."Clothier added "Taking supplements is risky for athletes as they can be contaminated or even adulterated with prohibited substances. Athletes owe it to their fellow competitors to be 100% certain before putting anything into their body. If there's the slightest doubt, leave it out."
