(BBC Sport) More than 10% of elite athletes could be using performance-enhancing drugs, says World Anti-Doping Agency director general David Howman. But he warns that the number of children doping to reach the elite level is Wada’s “biggest concern”. Howman said sport’s increasing profitability had led to young athletes becoming more “vulnerable”. Drug testing is limited in non-elite events, and Howman admits teenagers are “under the radar” of doping agencies.
He also said doping could become a criminal offence in five years.
