BACKGROUND MDMA markets have undergone substantial changes internationally, with increasing manufacture of high purity MDMA recorded. This study examined trends in MDMA-related deaths in Australia, investigating characteristics, circumstances and toxicology of these deaths. METHODS Analysis of MDMA-related deaths in Australia between 2001 and 2018, extracted from the National Coronial...
-fenfluramine, a selective serotonin-releasing compound. By dissociating the mechanisms of MDMA's prosocial effects from its addictive properties, we provide evidence for a conserved neuronal pathway, which can be leveraged to develop novel therapeutics with limited abuse liability.
3,4-methylenedioxymethamphetamine (MDMA) recently achieved breakthrough status from the Food and Drug Administration (FDA) for post-traumatic stress disorder (PTSD). However, evidence indicates that exposure to toxic doses of 3,4-methylenedioxymethamphetamine (MDMA) can lead to long-lasting dysregulation of brain monoaminergic neurotransmitters, primarily from studies conducted in young adult...
3,4-Methylenedioxymethamphetamine (MDMA), more commonly known as "ecstasy," is a semi-synthetic entactogenic phenylethylamine. In recent years it has gained popularity as a recreational drug whose use has registered an upward trend especially among adolescents and young adults. Despite its unwarranted reputation of being a "safe" drug, the actual scientific data denote that it actually leaves a...
Abstract Lysergic acid diethylamide (LSD) is a classic psychedelic, 3,4-methylenedioxymethamphetamine (MDMA) is an empathogen, and d -amphetamine is a classic stimulant. All three substances are used recreationally. LSD and MDMA are being investigated as medications to assist psychotherapy, and d -amphetamine is used for the treatment of attention-deficit/hyperactivity disorder. All three...
There is a renewed interest in the use of 3,4-methylenedioxymethamphetamine (MDMA) for treating psychiatric conditions. Although MDMA has entered phase II clinical trials and shows promise as an adjunct treatment, there is an extensive literature detailing the potential neurotoxicity and adverse neurobehavioral effects associated with MDMA use. Previous research indicates that the adverse...
MDMA (3,4-methylendioxymethamphetamine), also known as Ecstasy, is a stimulant drug recreationally used by young adults usually in dance clubs and raves. Acute MDMA administration increases serotonin, dopamine and noradrenaline by reversing the action of the monoamine transporters. In this work, we review the studies carried out over the last 30 years on the neuropsychobiological effects of...
A total of $17 million in private donations to the Hopkins center is expected to provide five years of operational funding for the center’s researchers and staff. The center will also train graduate students. With the aid of $17 million in private funds, Johns Hopkins University has launched a center to explore the potential of psychedelic compounds such as psilocybin (magic mushrooms) and...
3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) is a recreational substance also investigated as medication for posttraumatic stress disorder. Dopamine (DA) system stimulation likely contributes to the acute mood effects of amphetamines, including MDMA. Genetic variants, such as single-nucleotide polymorphisms (SNPs), and polymorphic regions of the DA system genes may in part explain...
Recreational abuse of illicit synthetic cathinones is an ongoing public health concern. Recent studies indicate that the methcathinone derivative 4-methylmethcathinone (4-MMC) produces behavioral and neurochemical effects similar to the entactogen 3,4-methylenedioxymethamphetamine (MDMA). Whereas polysubstance abuse is common, most preclinical studies of drug abuse liability only evaluate the...
Several studies strongly support the role of the dopamine D2-like and glutamate mGlu5 receptors in psychostimulant reward and relapse. The present study employed cocaine or MDMA self-administration with yoked-triad procedure in rats to explore whether extinction training affects the drug-seeking behavior and the D2-like and mGlu5 receptor Bmax and Kd values in several regions of the animal...
Background: Health professional students frequently use alcohol and narcotics. The potential impact on academic performance and professional behaviour is concerning.Aim: This study aimed to determine self-reported use of alcohol, illicit substances (e.g. cannabis, lysergic acid diethylamide [LSD], magic mushroom, cocaine, crack, ecstasy, methamphetamine and heroin), prescription medication and...
Unsuccessfully treated posttraumatic stress disorder (PTSD) is a serious and life-threatening disorder. Two medications, paroxetine hydrochloride and sertraline hydrochloride, are approved treatments for PTSD by the Food and Drug Administration (FDA). Analyses of pharmacotherapies for PTSD found only small to moderate effects when compared with placebo. The Multidisciplinary Association for...
Ecstasy or 3,4-methylenedioxymethamphetamine (MDMA) is an illicit recreational drug. Effects include euphoria, increased sensory awareness, and central stimulation. Although various arrhythmias, as well as dilated cardiomyopathy, have been previously noted to occur with chronic use, cardiac toxicities are seldom reported in an acute setting. Herein, we present a 28-year-old female patient with...
The psychostimulant drug ±3,4-methylenedioxymethamphetamine (MDMA) reportedly produces distinctive feelings of empathy and closeness with others. MDMA increases social behavior in animal models and has shown promise in psychiatric disorders, such as autism spectrum disorder (ASD) and post-traumatic stress disorder (PTSD). How it produces these prosocial effects is not known. This behavioral and...
3,4-Methylenedioxymethamphetamine (MDMA) is still one of the most consumed drugs by adolescents. Its abuse is related with cognitive impairment, which seems due to maladaptive plasticity and neural stress. In turn, new hypotheses suggest that Alzheimer's disease (AD) may be promoted by neural stressors. To test if there is an increase in vulnerability to AD after chronic MDMA consumption, we...
This article describes the development of the Sexual Ecstasy Scale, an instrument designed to measure the specific features that emerge when sexual arousal is the trigger for an ecstatic experience. Drawing from descriptions of features of sexual ecstasy in the phenomenological literature, the authors generated an initial survey of 31 items. In Study 1, the survey was completed by a wide...
MDMA has a variety of pro-social effects, such as increased friendliness and heightened empathy, yet there is a distinct lack of research examining how these effects might intertwine with a romantic relationship. This article seeks to compensate for this absence and explore heterosexual couples' use of MDMA through the lens of the boundaries they construct around these experiences. Three couple...
Novel psychoactive substances (NPS) are compounds designed to mimic the effects of existing recreational drugs (classical psychoactive substances [CPS]), while eluding established legal frameworks. Little is known about their effects and potential harms, rendering the increasing number of NPS a challenge to policy makers and researchers alike. Quantitative studies on the motives underlying NPS...
Posttraumatic stress disorder is a prevalent mental health condition with substantial impact on daily functioning that lacks sufficient treatment options. Here we evaluate six phase 2 trials in a pooled analysis to determine the study design for phase 3 trials of MDMA-assisted psychotherapy for PTSD. Six randomized, double-blind, controlled clinical trials at five study sites were conducted...
