ghb
GHB (gamma hydroxybutyrate) is a naturally occurring component of human cells. It is used most commonly in the form of a chemical salt (Na-GHB or K-GHB) which is taken recreationally as a depressant with effects quite similar to those of alcohol. These salts are powders but are most often mixed with water for recreational use. While GHB is most notorious for a few cases where it has been given to unsuspecting individuals, it is more commonly used as a recreational intoxicant like alcohol, as a sleep-aid, or as a supplement by body-builders.

One of the major concerns with GHB is that the recreational dosage range is narrow and even small overdoses can cause temporary unrousable unconsciousness (a type of coma) and large overdoses (poisonings) can be life-threatening. There are two other chemicals which are used as GHB equivalents: 1,4-butanediol and gamma butyrlactone.
