The interviewer, Mohan Govindasamy, then suggested that "everyone" at ESEA (E-Sports Entertainment Association) tournaments takes the drug. "Yeah," Friesen replied.

Adderall is a "smart drug" that's normally used to treat attention deficit hyperactivity disorder (ADHD). It helps the user concentrate, reduces fatigue and can also boost reaction times. Unsurprisingly, it's a popular choice for students cramming for exams. It's also been used by traditional athletes, and is mostly banned by the NFL, MLB and NHL. But Adderall abuse in eSports isn't new either. An anonymous player interviewed by Eurogamer said Adderall use was "very widespread" in the US eSports scene. In the same piece, Michal Blicharz, managing director of ESL, said drug abuse "did not seem commonplace" and that he doesn't believe players are using them to improve their performances.

Well, the recent interview with Friesen seems to suggest otherwise. It's hard to tell just how commonplace Adderall usage is right now, but if the eSports industry wants to be taken seriously, it needs to stamp out these performance-enhancing drugs quickly -- or risk a tarnished reputation similar to other popular sports such as road cycling.
