Drugs in sport: can science stop the cheats?

The World Anti-Doping Agency struggles to enforce rules against the International Olympic Committee's resistance while relying on evolving detection methods like the Athlete Biological Passport that capture only 1–2% of actual cases. High-profile admissions from athletes such as Marion Jones and Lance Armstrong, alongside whistleblower revelations, highlight a massive gap between official statistics and a 2011 survey suggesting 44% of competitors have doped. Although scientists like Dr. Yanis Pitsiladis are developing costly genetic sequencing to identify biomarker changes, severe funding limitations and rapid innovations in drug design continue to fuel a perpetual arms race between cheaters and authorities.
