What Are Club Drugs? Definition, Examples, Risks & Treatment

MDMA (methylenedioxymethamphetamine) is a man-made psychoactive substance. The primary mechanism of MDMA is to act as both a stimulant and a mild hallucinogen. MDMA is sold in two main forms: pressed pills or tablets, and powder or capsules. There are numerous street names for MDMA, including ecstasy, molly, Adam, and XTC.  Users report feelings of euphoric excitement and increased energy after consuming MDMA. The drug’s stimulant effects, which increase energy and reduce inhibition, helped drive its popularity in rave and dance club settings where extended physical activity and social engagement were central. However, MDMA has severe risks. MDMA rapidly elevates a user’s body temperature (hyperthermia), creating an extreme danger if consumed in excess amounts in warm/crowded areas. MDMA also significantly increases a user’s heart rate and blood pressure, placing additional stress on a user’s cardiovascular system.[3] 

In addition, MDMA reduces the availability of serotonin in a user’s brain. Prolonged MDMA use depletes serotonin over time, which can lead to lasting mood disturbances, cognitive difficulties, and memory loss. In reference to molly or ecstasy, it is very common for what is sold with this name to contain other active ingredients besides pure MDMA. Each dose therefore contains unknown quantities of other substances, posing varying degrees of risk.

GHB (gamma-hydroxybutyric acid) is a central nervous system depressant that occurs naturally in the brain in very small amounts as a byproduct of the neurotransmitter GABA. However, GHB can be synthesized and manufactured illegally in clandestine labs and then marketed and sold as a clear liquid or white powder. The street names for GHB are liquid ecstasy and Georgia Home Boy, and despite sharing a street name with ecstasy, GHB has no chemical relationship to MDMA. GHB was briefly approved for prescription use to treat narcolepsy via the brand name Xyrem, providing GHB with a legitimate medical history that contributes to misunderstanding its widespread misuse.

GHB is extremely hazardous to consume because there is only a small differential between what constitutes a recreational dose and a lethal dose. At low doses, GHB may produce feelings of euphoria and relaxation. At higher doses, it rapidly causes drowsiness, confusion, loss of consciousness, and respiratory depression.[4] Since GHB is almost completely undetectable in terms of appearance, color, or taste, it is often administered surreptitiously in beverage containers for purposes of committing drug-facilitated sexual assaults, earning GHB the status of a date-rape drug. When combined with alcohol/CNS depressants, GHB can induce rapid loss of consciousness/death.

Ketamine is an anesthetic agent used both clinically in humans and in veterinary medicine. Outside of clinical settings, ketamine goes by the street names Special K and Vitamin K. When misused, ketamine creates dissociative effects, causing users to become detached from their surroundings/environment and detached from their bodies. High doses create what is referred to as a k-hole, a profound state of dissociation and near immobility lasting approximately one hour.[5]

Ketamine affects blood pressure, impairs memory, concentration, and motor coordination, and due to its dissociative effects, significantly increases the risk of accidental injury while under its influence. Similar to other dissociatives or PCP-related substances, chronic misuse can lead to psychological dependence. Severe bladder and urinary tract damage resulting from chronic misuse has been reported uniquely associated with ketamine, requiring surgical intervention in severe cases.

Rohypnol is the trade name for flunitrazepam, a potent benzodiazepine with action profiles that are approximately 10 times stronger than Valium. Rohypnol acts similarly to other benzodiazepines, depressing the CNS and thereby inducing sedation, muscle relaxation, and amnesia. Flunitrazepam is not approved for medicinal use within the U.S., although it is used medicinally in some foreign countries. Within the U.S., flunitrazepam is listed as a Schedule IV controlled substance and is prohibited from production, distribution, and personal possession. 

Rohypnol has gained notoriety as a date-rape drug due to its ability to render victims incapacitated and rapidly unconscious with memory loss, thereby enabling perpetrators to commit crimes against victims without fear of resistance.[6]

LSD (lysergic acid diethylamide) is a hallucinogenic psychedelic with a high potency level that was created synthetically from a fungus found on grain crops. Hallucinogens distort sensory input and alter thought processes, thereby allowing users to perceive vivid visual and auditory hallucinations lasting 8-12 hours. 

LSD continues to be frequently found at raves and festival events. While LSD is not considered physically addictive in the way stimulants or depressants are, users can experience serious psychological distress from long-term use, including hallucinogen persisting perception disorder (HPPD) or drug-induced psychosis depending on individual vulnerabilities.
