Subacute effects of ecstasy on mood: an exploration of associated risk factors

The 21st century psychedelic renaissance: heroic steps forward on the back of an elephant

Given the plethora of new studies and published papers in the scientific press and the increasingly emerging presence of articles about positive psychedelic experiences appearing in the popular media, there is little doubt that we are in the midst of a Psychedelic Renaissance. The classical psychedelic drugs LSD and psilocybin and the entactogen MDMA are showing promise as tools to assist psychotherapy for a wide range of mental disorders, with multiple pilot studies demonstrating their safety and efficacy. In this article, the author describes how MDMA in particular has inherent characteristics that make it well suited for assisting trauma-focused psychotherapy in a population of patients who have experienced child abuse. But despite these advances, there remain many obstacles ahead of the widespread mainstream acceptance of psychedelic medicines. The author argues that the Misuse of Drugs Act 1971 is one such obstacle. Other impediments include a prevailing attitude of pseudoscience and rigidity from within the non-scientific psychedelic community itself. Resolution of these conflicts must be sought if medicine and society are to see psychedelics gaining a place in mainstream culture and science.

Why Psychiatry Needs 3,4-Methylenedioxymethamphetamine: A Child Psychiatrist's Perspective

Since the late 1980s the psychoactive drug 3,4-methylenedioxymethamphetamine (MDMA) has had a well-known history as the recreationally used drug ecstasy. What is less well known by the public is that MDMA started its life as a therapeutic agent and that in recent years an increasing amount of clinical research has been undertaken to revisit the drug's medical potential. MDMA has unique pharmacological properties that translate well to its proposed agent to assist trauma-focused psychotherapy. Psychological trauma-especially that which arises early in life from child abuse-underpins many chronic adult mental disorders, including addictions. Several studies of recent years have investigated the potential role of MDMA-assisted psychotherapy as a treatment for post-traumatic stress disorder, with ongoing plans to see MDMA therapy licensed and approved within the next 5 years. Issues of safety and controversy frequently surround this research, owing to MDMA's often negative media-driven bias. However, accurate examination of the relative risks and benefits of clinical MDMA-in contrast to the recreational use of ecstasy-must be considered when assessing its potential benefits and the merits of future research. In this review, the author describes these potential benefits and explores the relatives risks of MDMA-assisted psychotherapy in the context of his experience as a child and adolescent psychiatrist, having seen the relative limitations of current pharmacotherapies and psychotherapies for treating complex post-traumatic stress disorder arising from child abuse.

Simultaneous use of alcohol with methamphetamine but not ecstasy linked with aggression among young adult stimulant users

INTRODUCTION

Illicit stimulants are often combined with alcohol in nightlife entertainment districts, an environment where aggressive behaviour commonly occurs. While alcohol and methamphetamine use are each associated with aggressive behaviour, relatively little is known about the impact of the combined use of alcohol and amphetamine-type stimulants (i.e., ecstasy [MDMA] and methamphetamine) on aggression.

METHOD

Analysis of longitudinal data from a population-based sample of Australian young adult amphetamine-type stimulant users (n=248) to examine: (a) prevalence and timing of simultaneous alcohol and amphetamine-type stimulant use and (b) predictors of ecstasy- and methamphetamine-related aggression and hostility. Prediction models of ecstasy- and methamphetamine-related aggression and hostility were developed using multivariate logistic regression.

RESULTS

Simultaneous alcohol consumption and amphetamine-type stimulant use was prevalent, with drinking generally occurring before consuming amphetamine-type stimulants and while 'high'. Methamphetamine-related aggression and hostility was significantly associated with recurrent risky simultaneous methamphetamine and alcohol use (Adjusted Odds Ratio [AOR] 2.74, 95% CI 1.09-6.89), a high frequency and increasing use methamphetamine trajectory (AOR 7.23, 95% CI 1.27-41.03), and high trait aggression (AOR 5.78, 95% CI 2.53-13.20). In contrast, only trait aggression (moderate: AOR 3.01, 95% CI 1.55-5.84; high: AOR 5.02, 95% CI 2.38-10.61) was associated with ecstasy-related aggression and hostility.

CONCLUSIONS

These findings indicate a link between risky patterns of simultaneous alcohol and methamphetamine use and methamphetamine-related aggression and hostility, independent of separate use of alcohol, methamphetamine and cannabis, trait aggression, psychosis, and gender. The policy challenges of amphetamine-type stimulant and alcohol use require a targeted, multidisciplinary approach.

MDMA for the treatment of mood disorder: all talk no substance?

BACKGROUND

Unipolar depression is the third highest contributor to the global burden of disease, yet current pharmacotherapies typically take about 6 weeks to have an effect. A rapid-onset agent is an attractive prospect, not only to alleviate symptoms before first-line antidepressants display therapeutic action, but as a further treatment option in nonresponsive cases. It has been suggested that 3,4-methylene-dioxymethamphetamine (MDMA) could play a part in the treatment of depression, either as a rapid-onset pharmacological agent or as an adjunct to psychotherapy. Whilst these hypotheses are in keeping with the monoamine theory of depression and the principles surrounding psychotherapy, explicit experimental evidence of an antidepressant effect of MDMA has rarely been established.

AIMS

To address the hypothesis surrounding MDMA as a rapid-onset antidepressant by examining pharmacological, psychological and behavioural studies. We consider whether this therapy could be safe by looking at the translation of neurotoxicity data from animals to humans.

METHOD

A literature review of the evidence supporting this hypothesis was performed.

CONCLUSIONS

The pharmacology of MDMA offers a promising target as a rapid-onset agent and MDMA is currently being investigated for use in psychotherapy in anxiety disorders; translation from these studies for use in depression may be possible. However, experimental evidence and safety analysis are insufficient to confirm or reject this theory at present.
