BRADFORD, England – The director of London's anti-doping lab says next year's Olympics will be the "riskiest" for drug cheats.
Professor David Cowan says "huge advances" have been made in recent years to detect prohibited substances and methods. Authorities also are using intelligence gathering to crack down on doping.
Cowan heads the doping lab at King's College London, which will analyze more than 5,000 samples during the 2012 Olympics.
Speaking at a science conference Monday in Bradford, Cowan said "it's going to be the riskiest games for cheats." He hopes that by the time the Olympics begin scientists will devise a test to catch athletes who transfuse their own stored blood.
