Are these 'chemical' or 'biological' weapons we should be afraid of?:
(CNN) -- Less than a year from the 2004 Summer Olympics, the U.S. Anti-Doping Agency announced Thursday it had uncovered a doping "conspiracy" involving previously undetectable steroids used by track and field athletes. The agency said "several" track and field athletes tested positive for the THG (tetrahydrogestrinone) steroid, but did not identify them or their nationalities. The athletes, their governing bodies, and the U.S. Olympics Committee were all notified of the results. The USADA said it also contacted the U.S. Department of Justice "because this information pointed to potentially illegal activity by the distributor of a controlled substance."

"What we have uncovered appears to be intentional doping of the worst sort," according to a statement from USADA Chief Executive Officer Terry Madden. "This is a conspiracy involving chemists, coaches and certain athletes using what they developed to be 'undetectable' designer steroids to defraud their fellow competitors and the American and world public who pay to attend sporting events."
