Jamaican athlete Nesta Carter, who helped the 4×100 team to Olympic and World Championship titles, has tested positive for a banned stimulant in a retest of 454 samples from the Beijing Games.

The athlete’s ‘B’ sample is also said to have detected Methylhexanamine, the banned substance. The substance has been on the World Anti-Doping Agency prohibited list since 2004 although it was reclassified on the 2011 list as a “specified substance”. It was reclassified on the 2011 list as a “specified substance”, meaning one that is more susceptible to a “credible, non-doping explanation. Methylhexanamine, which has been used more recently as an ingredient in dietary supplements, used to be sold as a nasal decongestant in the United States until 1983. The sanction for its use has been a suspension of six months to a year and the loss of results from the period concerned.

Carter, the first-leg specialist in Jamaica’s dominant squad, assisted in winning gold medals at the 2008 and 2012 Olympics and the 2011, 2013, and 2015 world championships. Carter ran the opening leg of the relay event in which the team – also featuring Michael Frater, Usain Bolt, and Asafa Powell – clocked a then world-record time of 37.10 to take the 2008 title. Carter, the sixth fastest man of all time over 100m, has declined to make any comments till now.

Carter’s teammate Usain Bolt meanwhile said he would have no problem giving back one of his six Olympic gold medals if Carter is confirmed to have failed a drugs test. Bolt added it is heartbreaking to learn about the positive test because we have worked hard over the years to accumulate gold medals and work hard to be a champion. Bolt further said it will not be a problem for him if he needs to give back his gold medal.

The entire Jamaican relay team could be stripped of medals if one member is disqualified. If stripped of the gold medal, the dream of Bolt to match Carl Lewis’s nine Olympic gold medals as three in Rio would then still leave him one short.

Regarded as the fastest person ever timed, Usain Bolt recently recorded the second fastest time of the year in winning a 100m race in Jamaica. He ran 9.88 seconds at the Racers Grand Prix in Kingston. Bolt caught fellow Jamaicans Yohan Blake and Asafa Powell by 60m after a poor start before easing over the line. The 100m world record holder added he was “in good nick” ahead of Jamaica’s Olympic trials which start on 30 June.

Behind 9.58-second world record holder Bolt, every other man to run under 9.79 seconds has served a ban for drugs at some point in their career with Tyson Gay (9.69 seconds), Yohan Blake (9.69 seconds), Asafa Powell (9.72 seconds), and Justin Gatlin (9.74 seconds) all falling prey to anti-doping regulations. Carter, 30, is the sixth fastest 100m sprinter of all time with a personal best 9.78 seconds set in 2010. The Jamaican athlete has broken the 10-second barrier over 100m for every one of the past eight seasons and had his eyes set to represent Jamaica at this summer’s Rio Games.
