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. (Taurasi and another player, Monique Coker, tested at the same lab, were later cleared.) It is not clear how widespread this practice is. The BALCO scandal brought to light an as-yet unsubstantiated (but widely published) account of Major League Baseball's all-time leading home-run hitter Barry Bonds' supplemental chemical regimen that included modafinil in addition to anabolic steroids and human growth hormone. Modafinil has been shown to prolong exercise time to exhaustion while performing at 85% of VO2max and also reduces the perception of effort required to maintain this threshold. Modafinil was added to the World Anti-Doping Agency "Prohibited List" in 2004 as a prohibited stimulant (see Modafinil Legal Status).
