MLB's definition of "Drugs of Abuse". I can't tell how old this is, and although there is a section on punishment, it seems to specify punishment for a positive steroid test. I was also under the impression that the 50 game suspension was steroid specific. I just remembered that Neifi Perez was suspended for amphetamines. He has been suspended twice. His first suspension was for 25 games and followed his 2nd positive test. The second suspension was for 80 games. Apparently the first failed test gets you a warning.
