Club DrugsUnderstanding What They Are, Why People Use Them, and What They Do Thomas E. Freese, Ph.D. Director, Pacific Southwest Addiction Technology Transfer Center Director of Training, UCLA Integrated Substance Abuse Programs July 7, 2006
The Club Drugs • THE BIG ONES - • 3,4 methylenedioxymethamphetamine (Ecstasy) • Gamma Hydroxy Butyrate (GHB) • Ketamine • Nitrous Oxide • SOME NEW ONES • 2C-B • DXM
Ecstasy • MDMA technically 3,4 - Methylenedioxymethamphetamine • Hallucinogenic amphetamine • Releases serotonin and blocks reuptake • Dopamine and adrenergic effects
Ecstasy History • Developed and patented in Germany in 1912 by Merck • Stimulant properties were identified in 1933 • Scientific studies began in the 1970s • Used in psychotherapy in 70’s and early 80’s • MDMA emerged in mid 1980s on the “Rave Party Scene” • DEA Schedule 1 in 1985
Patterns of useThe Picture in the Late ‘90s • Third most used illicit drug • Used recreationally • Youth culture centered on “raves” • Trend in increase of injection

Ecstacy Tablets Anatomy of a Tab • different sizes & shapes • Typical X is 300 mg tab • 50-150 mg MDMA (maybe less) • coloring • binders coatings
MDMA Packaging • Tootsie rolls are softened & X hidden inside-- “Doing rolls” or “Rolling” • Skittles--X mixed in • Pez containers--they fit
Talk About Creative • Beaded necklaces for the pacifiers can be homemade; even the “fuzzies” come in kits. • Ravers have gone as far as drilling their X pills & stringing them into candy necklaces.
Ecstacy X Dosage & Ingestion • 50-150 mg MDMA in one 300 mg tab (lots of variability (50-300 mg/tab) • 1-3x a night • $25 per tablet • taken primarily orally • can be injected (IM, not IV) • Snorted Rectally (“Plugging“)
Ecstacy Onset & Duration of Effects Starts: 20 – 40 minutes Peaks: 2 – 4 hours Lasts: Physically: up to 8 hours Mentally: 24 – 48 hours Street names: Adam, X, XTC, e Drug class: Empathogen
Ecstacy Under the Influence • dilated pupils high temp • elevated pulse insomnia • hyperactive muscle rigidity • grinding teeth sweating • increased sensual perceptions • hallucinations rare CNS STIMULANT
Ecstacy X Dilated Pupils
Pharmacological effects • Initial enhancement of extracellular seratonin • Eventual decrease in seratonin levels • Effects are influenced by ambient temperature • Elevation of dopamine • Mediates effects of cocaine and amphetamine
Long-term effects • Neurotoxicity • Damage to neurons containing seratonin • Abnormalities in brain morphology • Short-term memory impairment
BRAIN CHANGES of Ecstasy users as well as people who abstain. Ecstasy users have far less serotonin activity (dark areas). May be permanent.
Effects of MDMA on Serotonin Transporters The Johns Hopkins Medical Institutions
Subjective Effects of MDMA • Altered time perception • Increased ability to interact with others • Decreased libido • Decreased defensiveness • Changes in visual perceptions • Increased awareness of emotions • Less impulsive
Physical effects • Pupil dilation • Nystagmus • Dry mouth • Loss of appetite • Bruxism (Jaw tension / teeth grinding) • Sweaty palms • Hot / cold flushes • Tachycardia • Motor tics • Headaches • Lethargy • Anorexia
Most significant acute adverse effects • Hyperthermia • Seizures • Disseminated intravascular coagulation • Renal and liver impairment • Rhabdomyolysis • Hyponatraemia • Confusion • Reduced consciousness • Seizures or convulsions
Other acute adverse effects • Seizures without hyperthermia or hyponatraemia • Hemorrhage due to changes in blood pressure • Respiratory difficulties • Chest pains associated with physical exertion • Ophthalmic complications
Psychological effects • Euphoria • Increased energy • Feeling of closeness • Depression • Increased restlessness • Increased anxiety • Decreased motivation • Anhedonia
Psychiatric sequelae • Depression • Panic disorders • Flashbacks • Delusions Risk is greatest when used repeatedly and in conjunction with other drugs
MDMA • Heavy MDMA have memory problems for at least 2 weeks after use - functional consequences • Reduction in number of serotonin transporters - PET Studies • Damage of serotonin nerve endings (Bolla, McCann & Ricaurte Neurology 51, 1998)
Ecstasy users had poorer performance in three general intelligence tests Journal of Neurology, Neurosurgery, and Psychiatry 2000; 68:719-725
Ecstasy users had poorer short-term memory performance than non-drug users Journal of Neurology, Neurosurgery, and Psychiatry 2000; 68:719-725
“Ecstasy-like” Drug • Paramethoxyamphetamine (PMA) – a dangerous hallucinogen with stimulant properties • Releases serotonin • Slow onset - people often take more and they may overdose • Not new - deaths were reported in 1970s
Street Development Gamma Hydroxy Butyrate (GHB)
GHB • Available in health food supplements until 1992. • Odorless liquid, frequently clear with a salty taste • Precursor, GBL available until recently in health food supplements
GHB • Hypnotic (nonanalgesic) anesthetic • Epileptogenic agent in animals • Increases growth hormone • Promotes slow wave sleep • Treatment of narcolepsy • Trials for the treatment of opiate and alcohol withdrawal
A Dose of GHB • 1 teaspoon (approx 2.5 g) - 4 tablespoons (30 g) • Dependent users 25 grams/day (357.14 mg/kg for a 70 kg man) • 50-70 mg/kg dose - anesthesia >60 mg/kg coma • Sleep studies - 50 - 60 mg/kg/night 2 doses • Alcohol studies - 50 - 150 mg/kg day divided doses
GHB Users - Rave/club crowd - Gay community - Exotic dancers/ strippers - Bodybuilders - Rapists - Individuals subject to random or mandatory drug testing
liquid: clear, odorless, colorless • salty taste • solid: white powder usually mixed in water • mixed in drinks to mask taste • one dose = 1/2 to 3 teaspoons (1/2 - 1 cap full) Gamma Hydroxy Butyrate (GHB)
Gamma hydroxy butyrate Onset & Duration of Effects • Cap concentration varies 500mg-5g • Rapidly absorbed, peak concentration 20-60 min • Almost completely oxidized to carbon dioxide • Readily crosses the blood brain barrier and placenta
