Here's the MLB drug policy. I know MiLB tests for a few more things, but I don't know if any of those are in the stimulant category. MLB drug policy - wikipedia As for the drugs on the list, only one has anti-inflammatory properties is famprofazone which metabolizes to methamphetamine. I can't find specific indications for this drug, which is unusual and likely means that it is not prescribed My speculation is this: Rodgers used some form of amphetamine derivative stimulant, tested positive once, tried to stop but had some problems with withdraw. I don't know the details, but if the first positive test only results in counseling, that might not be enough, and the teams / MLB /MiLB need to be more aggressive in treatments to prevent relapse. I also don't like how his agent tried to tie this to the carpal tunnel issue which seems dubious. The one thing that helped soften opinions here about Jeffress was the way Josh handled it.
