 However, the World Anti-Doping Agency (WADA) maintains that it was related to already banned substances.The Agency added modafinil to its list of prohibited substances on August 3, 2004, ten days before the start of the 2004 Summer Olympics.Modafinil has received some publicity in the past when several athletes (such as sprinter Kelli White in 2004, cyclist David Clinger and basketball player Diana Taurasi in 2010, and rower Timothy Grant in 2015) were discovered allegedly using it as a performance-enhancing doping agent.
