A Mixed-Method Analysis of Persisting Effects Associated with Positive Outcomes Following Ibogaine Detoxification

July 18, 2018 / Iboga / Ibogaine, Neuroscience, Papers, Psychology, Publications, Substance Use Disorder / By / , , , ,

Abstract

We examined persisting effects, self-perceived challenges, and potential benefits associated with positive outcomes following ibogaine detoxification using data collected as part of a larger online retrospective study of 73 patients who received treatment for chronic opioid use in Mexico between 2012 and 2015. A mixed-methods design was used comparing treatment responders versus non-responders, as well as content coding of themes from open-ended questions. Most participants reported positive persisting effects of ibogaine detoxification (e.g., enhanced personal sense of gratitude and authenticity, and meaning and appreciation for life). Compared to non-responders, treatment responders endorsed greater persisting changes in their ability to tolerate difficult/painful feelings, capacity for coping with stress, and reduced unhealthy anger. Treatment responders reported greater change in subjective levels of inner peace, joy, feelings of love/openheartedness, and experiences of sacredness in life. Qualitative analyses revealed that treatment responders reported a heightened sense of spiritual awareness and greater connection to their intra-/interpersonal relationships after ibogaine detoxification. Notable challenges of ibogaine detoxification included psychological and health-related difficulties during treatment and challenges with post-treatment integration. Findings highlight the persisting effects associated with positive response to ibogaine detoxification and possible post-treatment needs (i.e., more integration/aftercare resources). Future research using rigorous experimental designs is needed.

Dark Classics in Chemical Neuroscience: 3,4-Methylenedioxymethamphetamine

July 12, 2018 / Humanities & Art, MDMA, Neuroscience, Papers, Pharmacology & Chemistry, Psychiatry & Medicine, Psychology, Publications / 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 / Iboga / Ibogaine, Ketamine, LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, 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.

Rapid antidepressant effect of S-ketamine in schizophrenia.

July 2, 2018 / Depressive Disorders, Ketamine, Papers, Psychology, Psychotic Disorders, Publications / By / , , , , , ,

Abstract

Rapid anti-suicidal and antidepressant effects of ketamine have repeatedly been confirmed in unipolar and bipolar depression. Although meaningful antidepressant efficacy of ketamine has also been shown in depressed patients with a history of psychotic symptoms, its administration in psychotic disorders has largely been neglected due to its potential to exacerbate dissociative or psychotic symptoms. Presenting a case of a young female inpatient suffering from schizophrenia with a severe post-psychotic depression, we demonstrate a robust anti-suicidal and antidepressant effect of S-ketamine infusions administered thrice weekly for 3 weeks in total. Importantly, no relevant psychotic or dissociative symptoms occurred during the whole augmentation treatment period leading to a sustained remission of depressive symptoms and suicidality. Our safe and effective experience with intravenous S-ketamine might encourage researchers and clinicians to widen its administration range beyond the diagnosis of depression to enrich the current knowledge of ketamine effects in psychotic disorders.

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

June 29, 2018 / LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications / 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.

High dose psilocybin is associated with positive subjective effects in healthy volunteers

June 27, 2018 / Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , , , ,

Abstract

AIM:
The aim of the current study was to investigate the relationship between escalating higher doses of psilocybin and the potential psilocybin occasioned positive subjective effects.
METHODS:
Healthy participants ( n=12) were given three escalating doses of oral psilocybin (0.3 mg/kg; 0.45 mg/kg; 0.6 mg/kg) or (18.8-36.6 mg; 27.1-54.0 mg; 36.3-59.2 mg) a minimum of four weeks apart in a supervised setting. Blood and urine samples, vital signs, and electrocardiograms were obtained. Subjective effects were assessed using the Mystical Experience Questionnaire and Persisting Effects Questionnaire.
RESULTS:
There was a significant linear dose-related response in Mystical Experience Questionnaire total score and the transcendence of time and space subscale, but not in the rate of a complete mystical experience. There was also a significant difference between dose 3 compared to dose 1 on the transcendence of time and space subscale, while no dose-related differences were found for Mystical Experience Questionnaire total scores or rate of a mystical experience. Persisting Effects Questionnaire positive composite scores 30 days after completion of the last dose were significantly higher than negative composite scores. Persisting Effects Questionnaire results revealed a moderate increase in sense of well-being or life satisfaction on average that was associated with the maximum Mystical Experience Questionnaire total score. Pharmacokinetic measures were associated with dose but not with Mystical Experience Questionnaire total scores or rate of a mystical experience.
CONCLUSIONS:
High doses of psilocybin elicited subjective effects at least as strong as the lower doses and resulted in positive persisting subjective effects 30 days after, indicating that a complete mystical experience was not a prerequisite for positive outcomes.

Mental health of a self-selected sample of psychedelic users and self-medication practices with psychedelics

June 25, 2018 / LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / ,

Abstract

Background

A substantial number of people worldwide suffer from mental health problems during their lifetime. First-line treatments are not effective for everybody. Recent studies suggest that psychedelic drugs have high therapeutic potential for a variety of mental disorders.

Aims

This survey study aimed to assess the tendency of psychedelic users to self-medicate with psychedelics and to compare the effectiveness of self-administered psychedelics to treat their disorder and the treatment offered by a medical professional.

Methods and results

In total, 1,967 respondents consented were ≥18 years and completed the questionnaire. The mean (±SD) age was 25.9 (8.7); 79% were males, 20% females, and 1% classified themselves as “other.” Almost half of the respondents (46%) indicated to have suffered/to be suffering from a mental disorder, with 77% being diagnosed by a medical professional. In 99% of the diagnosed cases, the treatment was offered; 77% searched for treatments outside a medical professional’s recommendation with 81% who had used/were using psychedelics to treat/cure symptoms. Self-administered psychedelic treatment had a higher likelihood of being efficacious, with higher symptoms reduction and larger quality of life improvement compared to treatment offered by a medical professional.

Conclusions

Lifetime prevalence of psychopathologies in the current sample of psychedelic drug users seemed to be higher than in the general population. Self-medication with psychedelics was not highly frequent; although when it occurred, it was rated as significantly more effective as treatment offered by a medical professional. Current findings support research exploring the potential of psychedelics in the treatment of psychopathologies.

Psychedelic therapy for smoking cessation: Qualitative analysis of participant accounts

June 25, 2018 / Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , , , ,

Abstract

Background:

Recent pilot trials suggest feasibility and potential efficacy of psychedelic-facilitated addiction treatment interventions. Fifteen participants completed a psilocybin-facilitated smoking cessation pilot study between 2009 and 2015.

Aims:

The aims of this study were as follows: (1) to identify perceived mechanisms of change leading to smoking cessation in the pilot study; (2) to identify key themes in participant experiences and long-term outcomes to better understand the therapeutic process.

Methods:

Participants were invited to a retrospective follow-up interview an average of 30 months after initial psilocybin sessions. Semi-structured interviews were conducted with 12 of the 15 participants. Data were analysed using thematic analysis.

Results:

Participants reported gaining vivid insights into self-identity and reasons for smoking from their psilocybin sessions. Experiences of interconnectedness, awe, and curiosity persisted beyond the duration of acute drug effects. Participants emphasised that the content of psilocybin experiences overshadowed any short-term withdrawal symptoms. Preparatory counselling, strong rapport with the study team, and a sense of momentum once engaged in the study treatment were perceived as vital additional factors in achieving abstinence. In addition, participants reported a range of persisting positive changes beyond smoking cessation, including increased aesthetic appreciation, altruism, and pro-social behaviour.

Conclusions:

The findings highlight the value of qualitative research in the psychopharmacological investigation of psychedelics. They describe perceived connections between drug- and non-drug factors, and provide suggestions for future research trial design and clinical applications.
