Dr. Oz: Q&A: How did Lance get away with doping tests?

Q: So Lance Armstrong finally came clean. But he never tested positive for drugs. How did he get away with doping all those years? And can we ever trust athletes not to be dopers? – Mike C., Dunedin, Fla.

A: Armstrong had a lot of help along the way. He said he would get clean weeks before his races, and he was tipped off ahead of time before “random” testing was going to happen. But he wouldn’t be so successful at dodging detection today. The World Anti-Doping Agency, or WADA, now uses a protocol called the Athlete Biological Passport. By Lance’s own admission, it would have identified him for sure.
