Which substance is classified as a club drug?

Gamma Hydroxybutyrate (GHB) is classified as a club drug due to its common association with nightlife and party culture, particularly in environments like nightclubs, raves, and bars. This classification stems from its use for recreational purposes, often for its euphoric and sedative effects. GHB is known to be a central nervous system depressant and has gained notoriety because of its potential for misuse, particularly in cases of drug-facilitated sexual assault, which further emphasizes its connection to club environments where it may be surreptitiously administered.

In contrast, substances like oxycodone and morphine are primarily opioid medications prescribed for pain relief and, while they can be abused, they do not fit the profile of a club drug. Barbiturates, likewise, are central nervous system depressants, but they lack the specific association with the club scene that characterizes GHB. Thus, the unique cultural context and effects of GHB establish its classification as a club drug.
