September 8, 2018 / Anxiety disorders / PTSD, MDMA, Other subjects, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By / , , , , , ,

Abstract

RATIONALE:
Standard therapeutic approaches to reduce social anxiety in autistic adults have limited effectiveness. Since 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy shows promise as a treatment for other anxiety disorders, a blinded, placebo-controlled pilot study was conducted.
OBJECTIVES:
To explore feasibility and safety of MDMA-assisted psychotherapy for reduction of social fear and avoidance that are common in the autistic population.
METHODS:
Autistic adults with marked to very severe social anxiety were randomized to receive MDMA (75 to 125 mg, n = 8) or inactive placebo (0 mg, n = 4) during two 8-h psychotherapy sessions (experimental sessions) in a controlled clinical setting. Double-blinded experimental sessions were spaced approximately 1 month apart with 3 non-drug psychotherapy sessions following each. The primary outcome was change in Leibowitz Social Anxiety Scale (LSAS) Total scores from Baseline to one month after the second experimental session. Outcomes were measured again six months after the last experimental session.
RESULTS:
Improvement in LSAS scores from baseline to the primary endpoint was significantly greater for MDMA group compared to the placebo group (P = 0.037), and placebo-subtracted Cohen’s d effect size was very large (d = 1.4, CI - 0.074, 2.874). Change in LSAS scores from baseline to 6-month follow-up showed similar positive results (P = 0.036), with a Cohen’s d effect size of 1.1 (CI - 0.307, 2.527). Social anxiety remained the same or continued to improve slightly for most participants in the MDMA group after completing the active treatment phase.
CONCLUSIONS:
This pilot trial demonstrated rapid and durable improvement in social anxiety symptoms in autistic adults following MDMA-assisted psychotherapy. Initial safety and efficacy outcomes support expansion of research into larger samples to further investigate this novel treatment for social anxiety.

The influence of therapists’ first-hand experience with psychedelics on psychedelic-assisted psychotherapy research and therapist training

August 22, 2018 / MDMA, Mushrooms / Psilocybin, Papers, Psychiatry, Psychology, Psychotherapy, Publications / By / ,

Abstract

Clinical research on psychedelic-assisted psychotherapy is rapidly advancing in the USA, with two drugs, psilocybin and MDMA, progressing through a structure of FDA-approved trials on a trajectory toward Drug Enforcement Agency rescheduling for therapeutic use. Researcher’s and clinician’s personal use of psychedelics was cited as a potential confound in psychedelic research studies conducted in the 1950s and 1960s, a concern which contributed to the cessation of this research for some 20 years. Currently, there is no empirical research on personal use of psychedelics by current academic researchers and clinicians; its influence is undocumented, unknown, and undertheorized. This paper explores the history of personal use of psychedelics by clinicians and researchers, the potential impact of personal use on psychedelic-assisted psychotherapy and research, and the rationale for opening an academic discussion and program of research to investigate the role of personal use. We propose that there are factors unique to psychedelic-assisted therapy such that training for it cannot neatly fit into the framework of modern psychopharmacology training, nor be fully analogous to psychotherapy training in contemporary psychological and psychiatric settings. We argue that scientific exploration of the influence of therapists’ first-hand experience of psychedelics on psychedelic-assisted therapy outcomes is feasible, timely, and necessary for the future of clinical research.

Dark Classics in Chemical Neuroscience: 3,4-Methylenedioxymethamphetamine

July 12, 2018 / History, MDMA, Medicine, Neuroscience, Other subjects, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications, Safety, Toxicology / By / , ,

Abstract

Better known as “ecstasy”, 3,4-methylenedioxymethamphetamine (MDMA) is a small molecule that has played a prominent role in defining the ethos of today’s teenagers and young adults, much like lysergic acid diethylamide (LSD) did in the 1960s. Though MDMA possesses structural similarities to compounds like amphetamine and mescaline, it produces subjective effects that are unlike any of the classical psychostimulants or hallucinogens and is one of the few compounds capable of reliably producing prosocial behavioral states. As a result, MDMA has captured the attention of recreational users, the media, artists, psychiatrists, and neuropharmacologists alike. Here, we detail the synthesis of MDMA as well as its pharmacology, metabolism, adverse effects, and potential use in medicine. Finally, we discuss its history and why it is perhaps the most important compound for the future of psychedelic science-having the potential to either facilitate new psychedelic research initiatives, or to usher in a second Dark Age for the field.

Psychedelic-Assisted Psychotherapy: A Paradigm Shift in Psychiatric Research and Development.

July 5, 2018 / Consciousness, Iboga / Ibogaine, Ketamine, LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications / By /

Abstract

Mental disorders are rising while development of novel psychiatric medications is declining. This stall in innovation has also been linked with intense debates on the current diagnostics and explanations for mental disorders, together constituting a paradigmatic crisis. A radical innovation is psychedelic-assisted psychotherapy (PAP): professionally supervised use of ketamine, MDMA, psilocybin, LSD and ibogaine as part of elaborated psychotherapy programs. Clinical results so far have shown safety and efficacy, even for “treatment resistant” conditions, and thus deserve increasing attention from medical, psychological and psychiatric professionals. But more than novel treatments, the PAP model also has important consequences for the diagnostics and explanation axis of the psychiatric crisis, challenging the discrete nosological entities and advancing novel explanations for mental disorders and their treatment, in a model considerate of social and cultural factors, including adversities, trauma, and the therapeutic potential of some non-ordinary states of consciousness.

Positive psychology in the investigation of psychedelics and entactogens: A critical review

June 29, 2018 / LSD, MDMA, Mushrooms / Psilocybin, Papers, Personal development, Psychology, Publications, Safety / By / , , , , , ,

Abstract

RATIONALE:
We reviewed the concepts and empirical findings in studies with psychedelics and entactogens related to positive psychology – the study of healthy human functioning, well-being and eudaemonia. It is an unresolved question how beneficial effects of psychedelics and entactogens are related to the potential risks of these substances – particularly in non-clinical settings.
METHODS:
We searched in PubMed, PsychINFO and the Cochrane Library for controlled clinical and epidemiological studies which applied concepts from positive psychology. We included N = 77 eligible studies with 9876 participants published before November 1st, 2017: (1) quantitative studies (N = 54), (2) preliminary or exploratory studies and reviews not including meta-analyses (N = 17), and (3) studies evidencing primarily negative results (N = 6).
RESULTS:
Positive psychology concepts have been applied for measuring effects of clinical trials, recreational and ceremonial use of psychedelics and entactogens. Psychedelics and entactogens were shown to produce acute and long-term effects on mood, well-being, prosocial behaviours, empathy, cognitive flexibility, creativity, personality factors like openness, value orientations, nature-relatedness, spirituality, self-transcendence and mindfulness-related capabilities.
CONCLUSIONS:
There is preliminary evidence for beneficial effects of psychedelics and entactogens on measures of positive psychology in clinical and healthy populations, however their sustainability remains largely unresolved. The reported results must be considered preliminary due to methodological restrictions. Since longitudinal data on both positive and adverse effects of psychedelics are lacking, more rigorous and standardized measures from positive psychology should be applied in less biased populations with prospective longitudinal designs to carefully assess the benefit-risk-ratio.

Oxytocin receptor gene variations and socio-emotional effects of MDMA: A pooled analysis of controlled studies in healthy subjects

June 18, 2018 / MDMA, Neuroscience, Other subjects, Papers, Psychology, Psychopharmacology, Psychotherapy, Publications / By / ,

Abstract

Methylenedioxymethamphetamine (MDMA) increases oxytocin, empathy, and prosociality. Oxytocin plays a critical role in emotion processing and social behavior and has been shown to mediate the prosocial effects of MDMA in animals. Genetic variants, such as single-nucleotide polymorphisms (SNPs), of the oxytocin receptor (OXTR) may influence the emotional and social effects of MDMA in humans. The effects of common genetic variants of the OXTR (rs53576, rs1042778, and rs2254298 SNPs) on the emotional, empathogenic, and prosocial effects of MDMA were characterized in up to 132 healthy subjects in a pooled analysis of eight double-blind, placebo-controlled studies. In a subset of 53 subjects, MDMA produced significantly greater feelings of trust in rs1042778 TT genotypes compared with G allele carriers. The rs53576 and rs225498 SNPs did not moderate the subjective effects of MDMA in up to 132 subjects. None of the SNPs moderated MDMA-induced impairments in negative facial emotion recognition or enhancements in emotional empathy in the Multifaceted Empathy Test in 69 subjects. MDMA significantly increased plasma oxytocin concentrations. MDMA and oxytocin concentrations did not differ between OXTR gene variants. The present results provide preliminary evidence that OXTR gene variations may modulate aspects of the prosocial subjective effects of MDMA in humans. However, interpretation should be cautious due to the small sample size. Additionally, OXTR SNPs did not moderate the subjective overall effect of MDMA (any drug effect) or feelings of “closeness to others”.

A Survey of American Psychiatrists’ Attitudes Toward Classic Hallucinogens

June 1, 2018 / LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychiatry, Psychology, Psychotherapy, Publications, Safety, Sociology / By / , ,

Abstract

Recent years have seen renewed interest and research about the use of hallucinogens as possible agents in the treatment of psychiatric disorders. However, we are unaware of studies assessing the current attitudes of American psychiatrists regarding hallucinogens. Therefore, we e-mailed surveys to 1000 members of the American Psychiatric Association-250 resident-fellows and 750 attending psychiatrists. The response rate was 32.4%. Respondents tended to perceive hallucinogens as potentially hazardous and appropriately illegal for recreational purposes. However, a large minority expressed optimism about the potential use of hallucinogens for psychiatric treatment. Male and trainee respondents, as compared with female and attending respondents, reported less concern about the risks of hallucinogens and greater optimism about their therapeutic potential. Younger psychiatrists also seemed more optimistic. Optimism among trainees and younger psychiatrists may possibly reflect greater exposure to recent positive publications about hallucinogens and less awareness of more negative past reports.

Psilocybin and MDMA reduce costly punishment in the Ultimatum Game

May 29, 2018 / MDMA, Mushrooms / Psilocybin, Other subjects, Papers, Personality, Psychology, Publications / By / , , , , , ,

Abstract

Disruptions in social decision-making are becoming evident in many psychiatric conditions. These are studied using paradigms investigating the psychological mechanisms underlying interpersonal interactions, such as the Ultimatum Game (UG). Rejection behaviour in the UG represents altruistic punishment – the costly punishment of norm violators – but the mechanisms underlying it require clarification. To investigate the psychopharmacology of UG behaviour, we carried out two studies with healthy participants, employing serotonergic agonists: psilocybin (open-label, within-participant design, N = 19) and 3,4-methylenedioxymethamphetamine (MDMA; placebo-controlled, double-blind, crossover design, N = 20). We found that both MDMA and psilocybin reduced rejection of unfair offers (odds ratio: 0.57 and 0.42, respectively). The reduction in rejection rate following MDMA was associated with increased prosociality (R2 = 0.26, p = 0.025). In the MDMA study, we investigated third-party decision-making and proposer behaviour. MDMA did not reduce rejection in the third-party condition, but produced an increase in the amount offered to others (Cohen’s d = 0.82). We argue that these compounds altered participants’ conceptualisation of ‘social reward’, placing more emphasis on the direct relationship with interacting partners. With these compounds showing efficacy in drug-assisted psychotherapy, these studies are an important step in the further characterisation of their psychological effects.
