The World Anti-Doping Agency (WADA) is in crisis control. Again. Its latest fiasco concerns the Russian-based hacker outfit Fancy Bears, who have done sport a huge service. In publishing WADA’s Therapeutic Use Exemption (TUE) records of leading sportsmen and women, the hackers have revealed how the exemptions can be exploited legally by athletes to dope. An exemption allows athletes to take medications banned by WADA under normal circumstances, and while the majority of athletes on TUEs have legitimate medical conditions, it is easy to see how the system can be abused by a dodgy doctor.
