Mushrooms / Psilocybin

Twenty percent better with 20 micrograms? A qualitative study of psychedelic microdosing self-rapports and discussions on YouTube.

November 28, 2019 / LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / ,

Abstract

Background

Psychedelic microdosing is the trending practice of using tiny repeated doses of psychedelic substances to facilitate a range of supposed benefits. With only a few published studies to date, the subject is still under-researched, and more knowledge is warranted. Social media and internet discussion forums have played a vital role in the growing visibility of the microdosing phenomenon, and the present study utilized YouTube contents to improve comprehension of the microdosing practice as well as the social interactions and discussions around microdosing.

Methods

Microdosing self-disclosure in YouTube videos and their following comments were qualitatively analyzed by inductive thematic analysis. Various software was utilized to enable gathering and sorting relevant data.

Results

Microdosing of psychedelic substances, primarily LSD and psilocybin, was used for therapeutic and enhancement purposes, and predominantly beneficial effects were reported. Many different applications and outcomes were discussed, and therapeutic effects for depression appeared especially noteworthy. Intentions for use were recognized as an influencing factor for the progression and outcomes of microdosing. The function of social interactions was mainly to discuss views on the microdosing phenomenon, strategies for optimal results, minimize risks, and share emotional support.

Conclusions

Potentially, microdosing could provide some of the same benefits (for certain conditions) as full-dose interventions with less risk of adverse reactions related to the sometimes intense experiences of higher doses. Microdosing may well also mean additional benefits, as well as risks, through the repeated exposure over extended periods.

Microdosing psychedelics: Motivations, subjective effects and harm reduction

November 30, 2021 / LSD, Microdosing, Mushrooms / Psilocybin, Papers, Psychology / Leave a Comment / By / , , , ,

Abstract

Background: In recent years there has been growing media attention on microdosing psychedelics (e.g., LSD, psilocybin). This refers to people routinely taking small doses of psychedelic substances to improve mental health and wellbeing, or to enhance cognitive performance. Research evidence is currently limited. This paper examines microdosing motivations, dosing practices, perceived short-term benefits, unwanted effects, and harm reduction practices.

Methods: An international online survey was conducted in 2018 examining people’s experiences of using psychedelics. Eligible participants were aged 16 years or older, had used psychedelics and could comprehend written English. This paper focuses on 525 participants who were microdosing psychedelics at the time of the survey.

Results: Participants were primarily motivated to microdose to improve mental health (40%), for personal development (31%) and cognitive enhancement (18%). Most were microdosing with psilocybin (55%) or LSD/1P-LSD (48%). Principal components analysis generated three factors examining perceived short-term benefits of microdosing: improved mood and anxiety, enhanced connection to others and environment, and cognitive enhancement; and three factors examining negative and potentially unwanted effects: stronger-than-expected psychedelic effects, anxiety-related effects, and physical adverse effects. Most participants (78%) reported at least one harm reduction practice they routinely performed while microdosing.

Conclusion: Our findings suggest that people microdosing are commonly doing so as a self-managed therapy for mental health, either as an alternative or adjunct to conventional treatments. This is despite psychedelics remaining prohibited substances in most jurisdictions. Recent findings from clinical trials with standard psychedelic doses for depression and anxiety suggest that a neurobiological effect beyond placebo is not unreasonable. Randomised controlled trials are needed, complemented by mixed methods social science research and the development of novel resources on microdosing harm reduction.

Psilocybin-assisted therapy for depression: How do we advance the field?

November 22, 2019 / Depressive Disorders, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , , , ,

Abstract

In the quest for new treatment options for depression, attention is being paid to the potential role of psychedelic drugs. Psilocybin is of particular interest given its mechanism of action, its benefits in early trials and its relatively low side effects burden. This viewpoint outlines a number of key issues that remain to be elucidated about its potential use in the clinical environment, including clarification of the profile of people most likely to benefit and those who might experience adverse effects, longer-term outcomes and the role of psychotherapeutic input alongside the drug itself. There are also opportunities to understand better, the neurobiology underpinning its effects.

Serotonergic hallucinogens/psychedelics could be promising treatments for depressive and anxiety disorders in end-stage cancer.

October 28, 2019 / Anxiety Disorders / PTSD, Depressive Disorders, LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

In a recent issue of the BMC Psychiatry, the evidence of effectiveness of treatments for psychiatric conditions in end-stage cancer patients was reviewed (Johnson, 2018). The review was comprehensive, and included traditional and non-traditional/alternative treatments, including herbal medicines and spirituality. However, evidence showing that classic or serotonergic hallucinogens/psychedelics such as psilocybin and lysergic acid diethylamide (LSD) could be effective treatments for depressive and anxiety disorders in end-stage cancer was not included. In this commentary, we expand the information available on the original article by briefly reviewing data from recent placebo-controlled, double-blind, cross-over clinical trials showing evidence that administration of single (or few) doses of LSD and psilocybin was associated with rapid and sustained reductions in depressive and anxiety symptoms in patients with end-stage cancer and other life-threatening diseases (e.g., Bechterew’s disease, Parkinson’s disease, Celiac disease). Since these substances seem to produce rapid and sustained therapeutic effects with single (or few) doses and well tolerated, large-scale, prospective, multi-site studies of end-stage cancer and classical/serotonergic hallucinogens/psychedelics should be performed to improve our understanding of the therapeutic potentials of these drugs and their use on clinical practice.

The ethics of psychedelic research in disorders of consciousness.

October 9, 2019 / Ayahuasca, LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

This article provides an ethical analysis of psychedelic research involving disorders of consciousness patients. We apply two internationally accepted approaches for analyzing the ethics of human research, the Value-Validity Framework and Component Analysis, to a research program recently proposed by Scott and Carhart-Harris. We focus on Scott and Carhart-Harris’s proposal, but the ethical frameworks outlined are applicable to other novel research protocols in the science of consciousness.

The Psilocybin-Telomere Hypothesis: An Empirically Falsifiable Prediction Concerning the Beneficial Neuropsychopharmacological Effects of Psilocybin on Genetic Aging

September 24, 2019 / Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications / By /

Abstract

We introduce a novel hypothesis which states that the therapeutic utilisation of psilocybin has beneficial effects on genetic aging. Ex hypothesi, we predict a priori that controlled psilocybin interventions exert quantifiable positive impact on leucocyte telomere length (telomeres are a robust predictor of mortality and multifarious aging-related diseases). Our hypothesising follows the Popperian logic of scientific discovery, viz., bold (and refutable) conjectures form the very foundation of scientific progress. The ‘psilocybin-telomere hypothesis’ is formalised as a logically valid deductive (syllogistic) argument and we provide substantial evidence to support the underlying premises. Impetus for our theorising derives from a plurality of converging empirical sources indicating that psilocybin has persistent beneficial effects on various aspects of mental health (e.g., in the context of depression, anxiety, PTSD, OCD, addiction, etc.). Additional support is based on a large corpus of studies that establish reliable correlations between mental health and telomere attrition (improved mental health is generally correlated with longer telomeres). Another pertinent component of our argument is based on recent studies which demonstrate that “meditative states of consciousness” provide beneficial effects on genetic aging. Similarly, psilocybin can induce states of consciousness that are neurophysiologically and phenomenologically significantly congruent with meditative states. Furthermore, prior research has demonstrated that a single dose of psilocybin can occasion life-changing transformative experiences (≈ 70% of healthy volunteers rate their experience with psilocybin amongst the five personally most meaningful lifetime events, viz., ranked next to giving birth to a child or losing a loved one). We postulate that these profound psychological events leave quantifiable marks at the molecular genetic/epigenetic level. Given the ubiquitous availability and cost effectiveness of telomere length assays, we suggest that quantitative telomere analysis should be regularly included in future psilocybin studies as an adjunctive biological marker (i.e., to facilitate scientific consilience via methodological triangulation). In order to substantiate the ‘psilocybin-telomere hypothesis’ potential neuropsychopharmacological, endocrinological, and genetic mechanisms of action are discussed (e.g., HPA-axis reactivity, hippocampal neurogenesis, neurotropic growth factors such as BDNF, 5-HT2A receptor agonism, neuroplasticity/synaptoplasticity, brain-wide alterations in neuronal functional connectivity density, involvement of the SLC6A4 serotonin transporter gene, inter alia). The proposed research agenda is thus intrinsically highly interdisciplinary, and it has deep ramifications from a philosophy of science perspective as it connects the epistemic level (qualitative experiential phenomenology) with the ontic level (quantitative molecular genetics) of analysis. In the long term, multidisciplinary and innovative investigations of the ‘psilocybin-telomere hypothesis’ could contribute to the improvement of senotherapeutic psychological interventions and the identification of novel geroprotective and neuroprotective/restorative pharmaceutical targets to decelerate genetic aging and improve well-being and quality of life during the aging process.

The psychedelic renaissance: the next trip for psychiatry?

September 23, 2019 / Depressive Disorders, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications / By

Abstract

The psychedelic research renaissance is gaining traction. Preliminary clinical studies of the hallucinogenic fungi, psilocybin, with psychological support, have indicated improvements in mood, anxiety and quality of life. A seminal, open-label study demonstrated marked reductions in depression symptoms in participants with treatment-resistant depression (TRD). The associated neurobiological processes involve alterations in brain connectivity, together with altered amygdala and default mode network activity. At the cellular level, psychedelics promote synaptogenesis and neural plasticity. Prompted by the promising preliminary studies, a randomized, double-blind trial has recently been launched across Europe and North America to investigate the efficacy of psilocybin in TRD. One of these centres is based in Ireland – CHO Area 7 and Tallaght University Hospital. The outcome of this trial will determine whether psilocybin with psychological support will successfully translate into the psychiatric clinic for the benefit of patients.

Hallucinogens and Their Therapeutic Use: A Literature Review

September 1, 2019 / Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, DMT, Iboga / Ibogaine, Ketamine, LSD, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications / By / ,

Abstract

The exploration of possible therapeutic benefits of hallucinogenic substances has undergone a revitalization in the past decade. This literature review investigated the published literature regarding the psychotherapeutic uses of hallucinogens in psychiatric disorders. The results showed that a variety of substances have been evaluated in the treatment of psychiatric disorders, including ayahuasca, ibogaine, ketamine, lysergic acid diethylamide, 3,4-methylenedioxymethamphetamine, and psilocybin. The conditions treated ranged from depression to autism, with the largest volume of research dedicated to substance use disorders. The majority of studies that were reviewed demonstrated significant associations with improvement in the conditions investigated. However, it was difficult to draw definitive conclusions as most studies suffered from small sample sizes, inconsistent measures, and poor study design. To properly assess the risks and potential benefits of hallucinogens in psychiatric treatment, there is a need for well designed, standardized studies that demonstrate the impact of hallucinogenic substances on psychiatric conditions.

Psilocybin-assisted mindfulness training modulates self-consciousness and brain default mode network connectivity with lasting effects

August 1, 2019 / Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , ,

Abstract

Both psychedelics and meditation exert profound modulatory effects on consciousness, perception and cognition, but their combined, possibly synergistic effects on neurobiology are unknown. Accordingly, we conducted a randomized, double-blind, placebo-controlled study with 38 participants following a single administration of the psychedelic psilocybin (315 μg/kg p.o.) during a 5-day mindfulness retreat. Brain dynamics were quantified directly pre- and post-intervention by functional magnetic resonance imaging during the resting state and two meditation forms. The analysis of functional connectivity identified psilocybin-related and mental state–dependent alterations in self-referential processing regions of the default mode network (DMN). Notably, decoupling of medial prefrontal and posterior cingulate cortices, which is thought to mediate sense of self, was associated with the subjective ego dissolution effect during the psilocybin-assisted mindfulness session. The extent of ego dissolution and brain connectivity predicted positive changes in psycho-social functioning of participants 4 months later. Psilocybin, combined with meditation, facilitated neurodynamic modulations in self-referential networks, subserving the process of meditation by acting along the anterior–posterior DMN connection. The study highlights the link between altered self-experience and subsequent behavioral changes. Understanding how interventions facilitate transformative experiences may open novel therapeutic perspectives. Insights into the biology of discrete mental states foster our understanding of non-ordinary forms of human self-consciousness and their concomitant brain substrate.
