Olympic gold medallist Denise Lewis has called for lifetime bans for all drug cheats, after it emerged yesterday that three Jamaican athletes tested positive for banned substances.
Tyson Gay failed an out of competition test in May, and his compatriots Asafa Powell and Sherone Simpson also tested positive.
With the World Championships starting in Moscow in under a month's time, Lewis, who won Gold in the Heptathlon at the Sydney Olympics in 2000, wants the World Anti-Doping Agency to make a clear stance to athletes which substances are banned.
She said in an interview for Sky Sports News: "WADA and the organisation that looks after doping control need to make the list of banned substances a little bit clearer. Maybe there should be a list of certain supplements that the athletes are cleared to take. That may be the solution."
Athletics is a sport that has repeatedly suffered from athletes being caught using performance enhancing drugs, and an ongoing debate in the sport is whether athletes should be allowed to compete again after being found guilty, and Lewis feels there should be no way back for drug cheats.
"For those that have genuinely made a mistake then there might have to be some leniency but, for me personally, when you a cheating your number should be up," she said. "There is no place in our sport for you."
