Re: adderall in tennis, one ATP player told me today he estimates “half of top 100 is on it…maybe more.” And not because they have trouble focusing while doing their homework. Lots of cynicism about the TUE system within the locker room.
Through grape vines of pro tennis, I hear that many players are on ADHD meds to help sharpen focus and concentration in a manner that brings up integrity questions. Are ADHD meds the meldonium for the brain? Wonder how many current players have asked for a TUE for ADHD recently?
