So if you can find a doctor willing to prescribe anabolic steroids then their use should be allowed under baseball's rules? Because steroids are a perfectly legal (and in the cases of legitimate use serve a perfectly reasonable purpose) when prescribed by a licensed physician. The fact is drugs like Adderall can provide quite the pick me up when abused and its obvious that MLB is right to police it like they do when you realize that MLB players are "prescribed" this drug at a rate that far outpaces the general public. Amazing that so many MLB players are "afflicted" with ADHD.
But what really amazes me is that the MLB policy for a first positive test for use of an unapproved amphetamine is a warning, not a suspension. So Davis tested positive once before. How stupid can he be, especially given his public comments when confronted with the questions about his 50+ homer season. He was nearly as adamant about his opposition to PHDs as Rafael Palmiero was in that famous congressional hearing. Now he looks like just another lying MLB player, and that's a shame.
The stigma of PHDs is going to last for generations, no matter how well baseball cleans up it's act. The players would probably be better served by refusing to ever comment on them from now on. If they deny use when people ask them about 600 foot home runs or 175 RBI seasons half the public doesn't believe them anyway. And if - like Davis - they subsequently test positive, it damages their reputation even more than if they had never said a word.
