In a recent video interview, Kory "Semphis" Friesen , formerly of Cloud9 talked about using Adderall during a CS: GO tournament in March. Adderall is a prescription amphetamine abused by many competitive gamers to heighten focus and remain alert. Friesen claimed the entire team was using the drug at the time of the ESL Katowice One event last March. In response, the ESL has announced that it is taking measures to counteract doping during its events. The extent of these measures are yet to be determined, but it is an important step for professional gaming.
