Jeff Adams (born November 15, 1970 in Mississauga, Ontario) is a Canadian Paralympian and a six-time world champion in wheelchair sports.
Adams competed at six consecutive Summer Paralympics from 1988 to 2008, winning a total of three gold, four silver, and six bronze medals. At the 1988 Summer Paralympics he won two bronze medals, one in the 800m race and one in the 1500m race. Four years later at the Barcelona Games he won two silvers, one in the 800m race and one as part of the 4 × 400 m relay. At the 1996 Summer Paralympics he won gold in the 800 m, silver in the 400 m, and bronze in the 4×400 m relay. Four years later, at the Sydney games, he won five medals, a gold in the 800 m and 1500 m, a silver in the 400 m and a bronze in the 5000 m and 4x100 m. At the 2004 Paralympics he won a bronze in the 400 m race. Jeff was coached by the Swede Peter Eriksson.
Adams was suspended for two years for testing positive for cocaine at the 2006 Canadian wheelchair marathon championships in Ottawa. After the positive test, Adams asked for a hearing before an independent arbitrator, who determined he had committed an anti-doping violation, and that Adams should be suspended from competition for a two-year timeframe. Adams' suspension meant a loss of federal sport funding for life.
Adams filed an appeal with the Court of Arbitration for Sport in Lausanne, Switzerland, which ultimately went in his favour. A three-person arbitration panel found Adams' version of events to be true, and that the failed test was because of a contaminated piece of equipment. The panel added the athlete had been the victim of an assault at the bar and could not be held negligent or at fault, and also made an overt reference to Adams being "a person of high character".
