TORONTO (AP) - Canadian wheelchair racer Jeff Adams has been suspended from competition for two years after testing positive for cocaine.
The suspension was announced Tuesday by the Canadian Center for Ethics in Sport.
The violation occurred during an in-competition test conducted at last year's Canadian wheelchair marathon championships in Ottawa.
Adams says the positive test was the result of a contaminated catheter. His lawyer, Tim Danson, said in a news release that the banned substance was not in Adams' system at the time of the race. He also said that cocaine is not prohibited out-of-competition and has no performance enhancing qualities.
Adams asked for a hearing before an independent arbitrator, who determined he had committed a doping violation.
The positive test means Adams, 36, is ineligible to receive federal sport funding for life.
Adams, one of the world's most recognizable wheelchair athletes, has been an outspoken crusader for Paralympic sport. He is a four-time Paralympian and six-time world champion. At the 2000 Sydney Olympics, he won five medals - gold in the 800 and 1,500 meters, a silver in the 400 and a bronze in the 5,000 and 4x100 meter relay.
