Tennis journalist Ben Rothenberg wrote on Twitter that he was told that half of the top 50 players are taking Adderal and Kyrgios is not one of them.
The Australian reacted to that claim on social media as generally, he doesn't miss anything that happens in tennis. His reaction was one that is quite typical, short and sweet. Replying to the tweet by Rothenberg, Kyrgios simply wrote:
"LOL (laughing out loud), not me."
The subject became a topic after Fernando Verdasco got suspended for not renewing his exemption for the drug that he was prescribed for ADHD. Some players consider that legal doping and spoke out against it with Rothenberg claiming that sources told him it's prevalent among professional tennis players.
