This might not be true for him, but I was a high level youth athlete and in my contract at the time I had to get permission from club doctors to take a prescribed drug. Accutane was usually seen as banned due it only really being a cosmetic thing and may have negative performance characteristics. And obviously for people especially Jordan performance would come ahead of cosmetic. Also if your the greatest bball player of all time a billionaire and married to a supermodel it probably wouldnt bother me either.
