MDMA

A randomized, controlled pilot study of MDMA (± 3,4-Methylenedioxymethamphetamine)-assisted psychotherapy for treatment of resistant, chronic Post-Traumatic Stress Disorder (PTSD)

October 31, 2012 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By / , , ,

Abstract

Psychiatrists and psychotherapists in the US (1970s to 1985) and Switzerland (1988-1993) used MDMA legally as a prescription drug, to enhance the effectiveness of psychotherapy. Early reports suggest that it is useful in treating trauma-related disorders. Recently, the first completed pilot study of MDMA-assisted psychotherapy for PTSD yielded encouraging results. Designed to test the safety and efficacy of MDMA-assisted psychotherapy in patients with treatment-resistant PTSD; our randomized, double-blind, active-placebo controlled trial enrolled 12 patients for treatment with either low-dose (25 mg, plus 12.5 mg supplemental dose) or full-dose MDMA (125 mg, plus 62.5 mg supplemental dose). MDMA was administered during three experimental sessions, interspersed with weekly non-drug-based psychotherapy sessions. Outcome measures used were the Clinician-Administered PTSD Scale (CAPS) and the Posttraumatic Diagnostic Scale (PDS). Patients were assessed at baseline, three weeks after the second and third MDMA session (end of treatment), and at the 2-month and 1-year follow-ups. We found that MDMA-assisted psychotherapy can be safely administered in a clinical setting. No drug-related serious adverse events occurred. We did not see statistically significant reductions in CAPS scores (p = 0.066), although there was clinically and statistically significant self-reported (PDS) improvement (p = 0.014). CAPS scores improved further at the 1-year follow-up. In addition, three MDMA sessions were more effective than two (p = 0.016).

Quantitative Analysis of Narrative Reports of Psychedelic Drugs

June 1, 2012 / Ayahuasca, DMT, Iboga / Ibogaine, Ketamine, LSD, MDMA, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Publications, Salvia / Salvinorin A / By / , ,

Abstract

Background

Psychedelic drugs facilitate profound changes in consciousness and have potential to provide insights into the nature of human mental processes and their relation to brain physiology. Yet published scientific literature reflects a very limited understanding of the effects of these drugs, especially for newer synthetic compounds. The number of clinical trials and range of drugs formally studied is dwarfed by the number of written descriptions of the many drugs taken by people. Analysis of these descriptions using machine-learning techniques can provide a framework for learning about these drug use experiences.

Methods

We collected 1000 reports of 10 drugs from the drug information website Erowid.org and formed a term-document frequency matrix. Using variable selection and a random-forest classifier, we identified a subset of words that differentiated between drugs.

Results

A random forest using a subset of 110 predictor variables classified with accuracy comparable to a random forest using the full set of 3934 predictors. Our estimated accuracy was 51.1%, which compares favorably to the 10% expected from chance. Reports of MDMA had the highest accuracy at 86.9%; those describing DPT had the lowest at 20.1%. Hierarchical clustering suggested similarities between certain drugs, such as DMT and Salvia divinorum.

Conclusion

Machine-learning techniques can reveal consistencies in descriptions of drug use experiences that vary by drug class. This may be useful for developing hypotheses about the pharmacology and toxicity of new and poorly characterized drugs.

Could MDMA be useful in the treatment of post-traumatic stress disorder?

December 15, 2011 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By /

Abstract

In recent studies, 3,4-methylenedioxymethylamphetamine (MDMA) has shown promise in the treatment of post-traumatic stress disorder (PTSD) as an adjunct to post-trauma psychological therapy. However, because of historical associations with its use as the recreational drug ecstasy, MDMA research remains a controversial subject. Dr Sessa discusses these controversies and describes a UK-based MDMA/PTSD currently in development.

An honest look at the risks and benefits of MDMA

December 6, 2021 / MDMA, Publications / By

Addiction, one of the most important peer-reviewed journals on drug use and abuse, has published the results of a study regarding the use of recreational ecstacy use and potential cognitive damage – which turned out to be absent. The study is unique in that it compared ecstacy users with minimal to no other drug use and non-drug users from the same dance scene.

For years it has been assumed that cognitive skills such as learning and memory would be damaged by heavy ecstacy use. But previous studies always used subjects that also used other drugs, so it could not be determined whether the damage was due to ecstacy use or use of other drugs. This study offers a new light on the matter.

The same day, O Magazine published an article on MAPS’ study of the use of MDMA in psychotherapy for people suffering from PTSD. Sarah, who has suffered from PTSD for twenty years, tells the reader about her experiences with MDMA-assisted psychotherapy for PTSD. You can read the full article here.

MDMA-Assisted Psychotherapy Using Low Doses in a Small Sample of Women with Chronic Posttraumatic Stress Disorder

September 8, 2011 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By / , , , ,

Abstract

The purpose of this study was to investigate the safety of different doses of MDMA-assisted psychotherapy administered in a psychotherapeutic setting to women with chronic PTSD secondary to a sexual assault, and also to obtain preliminary data regarding efficacy. Although this study was originally planned to include 29 subjects, political pressures led to the closing of the study before it could be finished, at which time only six subjects had been treated. Preliminary results from those six subjects are presented here. We found that low doses of MDMA (between 50 and 75 mg) were both psychologically and physiologically safe for all the subjects. Future studies in larger samples and using larger doses are needed in order to further clarify the safety and efficacy of MDMA in the clinical setting in subjects with PTSD.

In Vivo Imaging of Cerebral Serotonin Transporter and Serotonin 2A Receptor Binding in MDMA and Hallucinogen Users

June 6, 2011 / Ayahuasca, DMT, LSD, MDMA, Mescaline / Cacti, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications, Salvia / Salvinorin A / By / , , , , , ,

Abstract

Context:
Both hallucinogens and 3,4-methylenedioxy-methamphetamine (MDMA or “ecstasy”) have direct agonistic effects on postsynaptic serotonin 2A receptors, the key site for hallucinogenic actions. In addition, MDMA is a potent releaser and reuptake inhibitor of presynaptic serotonin.

Objective:
To assess the differential effects of MDMA and hallucinogen use on cerebral serotonin transporter (SERT) and serotonin2Areceptor binding.

Design:
A positron emission tomography study of 24 young adult drug users and 21 nonusing control partici-pants performed with carbon 11 (11C)–labeled 3-amino-4-[2-[(di(methyl)amino)methyl]phenyl]sulfanylbenzo-nitrile (DASB) and fluorine 18 (18F)–labeled altanserin, respectively. Scans were performed in the user group after a minimum drug abstinence period of 11 days, and the group was subdivided into hallucinogen-preferring users (n = 10) and MDMA-preferring users (n = 14).

Participants:
Twenty-four young adult users of MDMA and/or hallucinogenic drugs and 21 nonusing controls.

Main Outcome Measures:
In vivo cerebral SERT and serotonin 2A receptor binding.

Results:
Compared with nonusers, MDMA-preferring users showed significant decreases in SERT nondisplaceable binding potential (neocortex, −56%; pallidostriatum, −19%; and amygdala, −32%); no significant changes were seen in hallucinogen-preferring users. Both cortical and pallidostriatal SERT nondisplaceable binding potential was negatively correlated with the number of life-time MDMA exposures, and the time of abstinence from MDMA was positively correlated with subcortical, but not cortical, SERT binding. A small decrease in neocortical serotonin 2A receptor binding in the serotonin 2A receptor agonist users (both user groups) was also detected.

Conclusions
We found evidence that MDMA but not hallucinogen use is associated with changes in the cerebral presynaptic serotonergic transmitter system. Because hallucinogenic drugs primarily have serotonin 2A receptor agonistic actions, we conclude that the negative association between MDMA use and cerebral SERT binding is mediated through a direct presynaptic MDMA effect rather than by the serotonin 2A agonistic effects of MDMA. Our cross-sectional data suggest that subcortical, but not cortical, recovery of SERT binding might take place after several months of MDMA abstinence.

Residual neurocognitive features of long-term ecstasy users with minimal exposure to other drugs

February 15, 2011 / MDMA, Neuroscience, Papers, Psychology, Publications / By / , , , , ,

Abstract

Aims: In field studies assessing cognitive function in illicit ecstasy users, there are several frequent confounding factors that might plausibly bias the findings toward an overestimate of ecstasy-induced neurocognitive toxicity. We designed an investigation seeking to minimize these possible sources of bias.

Design: We compared illicit ecstasy users and non-users while (1) excluding individuals with significant life-time exposure to other illicit drugs or alcohol; (2) requiring that all participants be members of the ‘rave’ subculture; and (3) testing all participants with breath, urine and hair samples at the time of evaluation to exclude possible surreptitious substance use. We compared groups with adjustment for age, gender, race/ethnicity, family-of-origin variables and childhood history of conduct disorder and attention deficit hyperactivity disorder. We provide significance levels without correction for multiple comparisons.
Setting: Field study.
Participants: Fifty-two illicit ecstasy users and 59 non-users, aged 18–45 years.
Measurements: Battery of 15 neuropsychological tests tapping a range of cognitive functions.
Findings: We found little evidence of decreased cognitive performance in ecstasy users, save for poorer strategic self-regulation, possibly reflecting increased impulsivity. However, this finding might have reflected a pre-morbid attribute of ecstasy users, rather than a residual neurotoxic effect of the drug. Conclusions In a study designed to minimize limitations found in many prior investigations, we failed to demonstrate marked residual cognitive effects in ecstasy users. This finding contrasts with many previous findings—including our own—and emphasizes the need for continued caution in interpreting field studies of cognitive function in illicit ecstasy users.

Is Ecstasy an “Empathogen”? Effects of ±3,4-Methylenedioxymethamphetamine on Prosocial Feelings and Identification of Emotional States in Others

December 15, 2010 / MDMA, Papers, Psychology, Publications / By / , ,

Abstract

Background: Users of MDMA (“ecstasy”) report that the drug produces unusual psychological effects, including increased empathy and prosocial feelings. These “empathogenic” effects are cited as reasons for recreational ecstasy use and also form the basis for the proposed use of MDMA in psychotherapy. However, they have yet to be characterized in controlled studies. Here, we investigate effects of MDMA on an important social cognitive capacity, the identification of emotional expression in others, and on socially relevant mood states.

Methods: Over four sessions, healthy ecstasy-using volunteers (n = 21) received MDMA (.75, 1.5 mg/kg), methamphetamine (METH) (20 mg), and placebo under double-blind, randomized conditions. They completed self-report ratings of relevant affective states and undertook tasks in which they identified emotions from images of faces, pictures of eyes, and vocal cues.

Results: MDMA (1.5 mg/kg) significantly increased ratings of feeling “loving” and “friendly”, and MDMA (.75 mg/kg) increased “loneliness”. Both MDMA (1.5 mg/kg) and METH increased “playfulness”; only METH increased “sociability”. MDMA (1.5 mg/kg) robustly decreased accuracy of facial fear recognition relative to placebo.

Conclusion: The drug MDMA increased “empathogenic” feelings but reduced accurate identification of threat-related facial emotional signals in others, findings consistent with increased social approach behavior rather than empathy. This effect of MDMA on social cognition has implications for both recreational and therapeutic use. In recreational users, acute drug effects might alter social risk-taking while intoxicated. Socioemotional processing alterations such as those documented here might underlie possible psychotherapeutic benefits of this drug; further investigation of such mechanisms could inform treatment design to maximize active components of MDMA-assisted psychotherapy.

Trouw: Ecstasy against PTSD

December 6, 2021 / MDMA, Publications / By

In anticipation of our conference, which took place last weekend, newspaper Trouw published an article in which Joost Breeksema (president of the OPEN Foundation) is interviewed. Today the newspaper writes about the research into the treatment of PTSD with MDMA that Peter Oehen presented at the conference. 

Trouw: “The study showed that patients, after the treatment with MDMA, experienced less anxiety and were better able to tolerate negative emotions. Moreover, they experienced less emotional and physical pain.”

DEA approves MDMA/PTSD study

December 6, 2021 / MDMA, Publications / By

More news on the subject of research: on august 27th 2010 the DEA, an American government organisation in charge of the laws regarding ‘controlled substances’ in the US, has approved a study regarding the effects of MDMA on war veterans suffering from post-traumatic stress syndrome. MAPS can go ahead with the research, which will cost $500,000 and will take the good part of two years. Most of the budget still has to be found, but it’s a step in the right direction!

On the OPEN conference (october 23/24) you can hear more about these kinds of studies. Click here for more information.
