A piece from the Biz of Baseball as they spell out what, exactly, MLB considers a "drug of abuse":
Drugs of abuse are classified as:
1. Cocaine
2. LSD
3. Marijuana
4. Opiates (e.g., Heroin, Codeine, Morphine)
5. MDMA (“Ecstasy”)
6. GHB; and
7. Phencyclidine (“PCP”)
We didn't come out here to play tiddlywinks, son.
