The Beijing Games could provide a record haul of drug cheats because more testing will be done and the tests themselves are better, World Anti-Doping Agency chief John Fahey said Thursday, according to DPA. The WADA boss said 4,500 samples would be scrutinized - a quarter more than in Athens four years ago - and that there was pressure from within sport for athletes to be drug-free. "I believe there's a far greater awareness within individual teams of the need to be clean," he told Australia's ABC Radio. "I also believe that the resources on the ground that China are providing is quite impressive." There were 24 drug busts at the Athens Olympics.
