The question is not about whether Maria Sharapova should have known meldonium was added to the banned list for 2016.
The question is why she has been taking this since the age of 16 for an "abnormal EKG" diagnosed by her personal physician.
MLB players have *astonishingly* high rates of adult ADHD which requires treatment with amphetamines.
Pro cyclists are cursed, apparently, with almost universal asthma, requiring bronchodilator use.
Medical exemptions and dubious diagnoses from personal physicians are severely abused ways to get around doping bans and Rx-only regulations.
It's still cheating.
