Esports organisation ESL is investigating performance-enhancing drug use after a player admitted all his teammates used Adderall during a pro tournament.

Counter-Strike: Global Offensive player Kory "Semphis" Friesen said during an interview with fellow player Mohan "Launders" Govindasamy that "we were all on Adderall. It was pretty obvious if you listen to the comms."

Govindasamy seemed nonplussed at the notion, saying "everyone does Adderall at ESEA LAN, right?"

Unlike Govindasamy, the ESL does not take performance-enhancing drugs as a given, and is looking into ways to curb their use.

Said ESL rep Anna Rozwandowicz, "PEDs are a topic we are discussing at an organizational level and will be one that we need to address industry wide going forward to maintain the integrity of our sport."

A different source close to the ESL told the Daily Dot that the organisation would begin random drug testing via urinalysis, with the assistance of the World and National Anti-Doping Agencies.
