Professional video gamers will soon be subjected to the same scrutiny as professional athletes.

The largest and oldest professional video game organization, the Electronic Sports League (ESL), announced in a statement Thursday that starting in August they’ll begin testing gamers for performance enhancing drugs.

“As the world’s largest and oldest esports organization, ESL has an ongoing commitment to safeguarding both the integrity of our competitions and that of esports as a whole – we wish to ensure we can provide a fair playing field for all participating players,”a post on ESL’s website reads.

The first tests will be administered at the ESL One Cologne event in August, according to the statement.

Sports Illustrated reports the announcement comes in the wake of a scandal surrounding a team that admitted to taking the anti hyperactivity and attention deficit correction drug Adderall during a recent competition.
