Club drugs are the same as party drugs or synthetic drugs. These terms widely refer to a number of illicit drugs commonly used and abused by mid- to late- teens and crowds in their twenties often in late night club scenes and parties. The primary club drugs are MDMA, the active ingredient in Ecstasy, Ketamine (also known as Special K), LSD (d-lysergic diethylamide), and GHB (gamma-Hydroxybutyric acid). These synthetic (man-made) drugs have a variety dangerous hallucinogenic, psychedelic, and stimulant effects. Research has shown that club drugs can have long-lasting negative effects on the brain, especially on memory function and motor skills.
