Symptoms of anxiety and depression in childhood and use of MDMA: prospective, population based study

BMJ February 24, 2006 Anja C. Huizink, Robert F Ferdinand, Jan Van der Ende et al. 77 citations

OBJECTIVE: To investigate whether using ecstasy (3,4-methylenedioxymethamphetamine, MDMA) is preceded by symptoms of behavioural and emotional problems in childhood and early adolescence. DESIGN: Prospective, longitudinal, population based study SETTING: The Dutch province of Zuid-Holland. PARTICIPANTS: A sample of 1580 individuals, followed up across a 14 year period, from childhood into...

Effects of MDMA, MDA and MDEA on blood pressure, heart rate, locomotor activity and body temperature in the rat involveα‐adrenoceptors

British Journal of Pharmacology February 20, 2006 Sotiria Bexis, James R. Docherty 62 citations

The effects of injection of 3,4‐methylenedioxymethamphetamine (MDMA), 3,4‐methylenedioxyamphetamine (MDA) and N ‐ethyl‐3,4‐methylenedioxyamphetamine (MDEA) (all 20 mg kg −1 ) on blood pressure, heart rate, core body temperature and locomotor activity in conscious rats were investigated using radiotelemetry. MDMA and MDA produced a prolonged increase in both systolic and diastolic pressures,...

Pharmacokinetic profile of single and repeated oral doses of MDMA in squirrel monkeys: relationship to lasting effects on brain serotonin neurons.

Neuropsychopharmacology February 2006 Annis O. Mechan, Jie Yuan, George Hatzidimitriou et al.

A large body of data indicates that (+/-)3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') can damage brain serotonin neurons in animals. However, the relevance of these preclinical data to humans is uncertain, because doses and routes of administration used in animals have generally differed from those used by humans. Here, we examined the pharmacokinetic profile of MDMA in squirrel monkeys...

Elevated impulsivity and impaired decision-making cognition in heavy users of MDMA (“Ecstasy”)

Psychopharmacology January 20, 2006 Boris B. Quednow, K. Kühn, C. Hoppe et al.

RationaleIn animal studies, the common club drug 3,4-methylendioxymethamphetamine (MDMA, “Ecstasy”) consistently caused a prolonged loss of presynaptic serotonergic neurons, and evidence suggests that MDMA consumption may also affect the human serotonergic system. Serotonin (5-HT) has been implicated in the regulation of impulsivity and such executive functions as decision-making cognition. In...

L-Tyrosine Contributes to (+)-3,4-Methylenedioxymethamphetamine-Induced Serotonin Depletions

Journal of Neuroscience January 4, 2006 Joseph M. Breier, Michael G. Bankson, Bryan K. Yamamoto

The specific mechanisms underlying (+)-3,4-methylenedioxymethamphetamine (MDMA)-induced damage to 5-HT terminals are unknown. Despite the hypothesized role for dopamine (DA) and DA-derived free radicals in mediating this damage, it remains unclear why MDMA produces long-term depletions of 5-HT in brain regions that are sparsely innervated by DA neurons. We hypothesized that the precursor to DA...

Simulated Driving and Attention of Repeat Users of MDMA and THC Compared with THC Users and Non-Drug-Using Controls

Transportation Research Record: Journal of the Transportation Research Board 2006 Caroline T. J. Lamers, Matthew Rizzo, Antoine Bechara et al.

The aim of the study is to assess if cognitive impairments in abstinent users of methylenedioxymethamphetamine (MDMA) are due to repeated use of MDMA or concurrent drugs of abuse and how these impairments interfere with key activities of daily life such as automobile driving. Simulated driving performance and attention of 12 users of MDMA and marijuana [tetrahydrocannabinol (THC)] (MDMA/THC),...

Increased responsiveness to MDMA in adult rats treated neonatally with MDMA.

Neurotoxicology and Teratology 2006 Brian J. Piper, Jerrold S. Meyer

MDMA [(+/-)3,4-methylenedioxymethamphetamine, also known as ecstasy] is a popular recreational drug among women of reproductive age. The objective of this study was to investigate the long-term neurobehavioral consequences of early developmental MDMA exposure. On postnatal days (PD) 1-4, Sprague-Dawley rats received two 10 mg/kg injections of MDMA with an inter-dose interval of 4 h. Male...

MDMA administration to pregnant Sprague-Dawley rats results in its passage to the fetal compartment.

Neurotoxicology and Teratology 2006 Nicholas G Campbell, James B. Koprich, Nicholas M Kanaan et al.

Recent investigations have demonstrated that prenatal 3,4-methylenedeoxymethamphetamine (MDMA; ecstasy) exposure in rats results in significant and persistent changes in the developing brain. However, no published pharmacokinetic studies exist demonstrating that MDMA administered during pregnancy passes to the fetal compartment. This leaves open the question whether MDMA is directly acting on...

From "Male Bonding Rituals" to "Suicide Tuesday": A qualitative study of issues faced by gay male ecstasy (MDMA) users.

Journal of Homosexuality 2006 Robert Klitzman

Use of MDMA and other club drugs has increased among gay men, but questions remain concerning the use, context, and popularity of these drugs; and views of their side effects. We interviewed in-depth 12 gay MDMA users in New York. MDMA had specific appeals to gay men, who often described isolation and stigmatization. Users underwent a period of initiation and social networks often became...

Ecstasy-induced cell death in cortical neuronal cultures is serotonin 2A-receptor-dependent and potentiated under hyperthermia.

Neuroscience 2006 J P Capela, Karsten Ruscher, M Lautenschlager et al.

Studies on 3,4-methylenedioxymethamphetamine ("ecstasy")-induced neurotoxicity mainly focus on damage of serotonergic terminals. Less attention has been given to neuronal cell death produced by 3,4-methylenedioxymethamphetamine and other amphetamines in areas including the cortex, striatum and thalamus. In the present study we investigated 3,4-methylenedioxymethamphetamine-induced neurotoxicity...
