"The retestings could be the tip of a doping iceberg, Pipe suggested. Thousands of urine samples dating back several years are frozen at the Olympic-approved Montreal lab. Pipe said that as the identities of athletes who fail a new test become known, the CCES would consider looking back at old samples to find out how long the athlete had been using the drug and when its use became popular in the doping underground."
