Gamma Hydroxybutyric Acid, commonly abbreviated GHB, is a therapeutic drug which is illegal in multiple countries. It is currently regulated in the US and sold by Jazz Pharmaceuticals under the name Xyrem. However, it is important to note that GHB is a designated Orphan drug (in 1985). Today Xyrem is a Schedule III drug; however GHB remains a Schedule I drug and the illicit use of Xyrem falls under penalties of Schedule I. GHB is a naturally occurring substance found in the central nervous system, wine, beef, small citrus fruits and almost all other living creatures in small amounts. It is used illegally under the street names Juice, Liquid Ecstasy or simply G, either as an intoxicant, or as a date rape drug. Xyrem is a central nervous system depressant that reduces excessive daytime sleepiness and cataplexy in patients with narcolepsy.    From: DrugBank
