Former WADA vice president Arne Ljungqvist disclosed that well-known athletes have legally used banned substances like ADHD drugs after receiving Therapeutic Use Exemptions. A Russian documentary and leaks from the hacker group "Fancy Bears" revealed Therapeutic Use Exemption documents showing that athletes like Serena Williams, Bradley Wiggins, and Simone Biles had been granted permission to take otherwise banned medications. The exemptions and leaks led to an investigation into whether some Therapeutic Use Exemption documents had been falsified.

2. Former World Anti-Doping Agency (WADA) vice
president Arne Ljungqvist has disclosed that well-known
athletes have "legally" used banned substances after they
received permission for their use to treat Attention Deficit
Hyperactivity Disorder (ADHD).
Ljungqvist, who served as WADA vice-president from
2008 to 2013, made the comments in a documentary film
shown on Russian television station Channel One. This
program led to an investigation into allegedly-falsified
Therapeutic Use Exemption (TUE) documents that
allowed many athletes to take the banned drugs.

group ‘Fancy Bears’ that disclosed six lists of athletes
who have been granted Therapeutic Use Exemptions
that permit them to take medication at the time of
competition. These list included big names such as
American tennis champion Serena Williams, British
cyclist Bradley Wiggins, and Team USA’s four-time
Olympic gymnastics gold medalist Simone Biles.
