Microdosing

The therapeutic potential of microdosing psychedelics in depression

November 18, 2021 / Depressive Disorders, LSD, Microdosing, Mushrooms / Psilocybin, Papers, Psychology / Leave a Comment / By /

Abstract

Microdosing psychedelics is the repeated use of small doses of, for example, lysergic acid diethylamide (LSD) and psilocybin, typically for a few weeks. Despite the popular and scientific attention in recent years, and claims by users that it has therapeutic value in affective disorders like depression, little scientific knowledge is available to back this. The purpose of this review was to investigate whether there are scientific grounds to state that this practice could be helpful in the treatment of affective disorders, and safe to use repeatedly. To that end, the literature (PubMed, MedLine) was searched, looking for (controlled) experimental studies with low doses of LSD and/or psilocybin, in healthy volunteers and patient samples. After a selection process and the addition of relevant articles, 14 experimental studies entered this review. Findings show that both LSD (10-20 mcg) and psilocybin (<1-3 mg) have subtle (positive) effects on cognitive processes (time perception, convergent and divergent thinking) and brain regions involved in affective processes. Besides the pleasant experience, increased anxiety and a cycling pattern of depressive and euphoric mood were also found. With regard to safety, it was demonstrated that low doses are well tolerated (in healthy volunteers) and have no-to-minimal effects on physiological measures. While it is yet unclear whether psychedelic microdosing is of therapeutic value for depression, the aforementioned effects on selective processes suggest that low doses of psychedelics could play a role in depression by inducing some kind of cognitive flexibility, which might lead to decreased rumination. While previous studies were conducted mostly in small samples of healthy volunteers, future placebo-controlled clinical trials in depressed patients are required to understand the therapeutic value of microdosing psychedelics, how this differs from therapy using full psychedelic doses, and whether different psychedelics have different effect patterns. The proposed research will give new insights into the potential of future alternative psychiatric treatment forms that are fiercely needed.

Psychedelics as a Treatment for Alzheimer’s Disease Dementia

January 3, 2022 / LSD, Microdosing, Mushrooms / Psilocybin, Neuroscience, Papers / Leave a Comment / By / ,

Abstract

Currently, there are no disease-modifying treatments for Alzheimer’s disease (AD) or any other dementia subtype. The renaissance in psychedelic research in recent years, in particular studies involving psilocybin and lysergic acid diethylamide (LSD), coupled with anecdotal reports of cognitive benefits from micro-dosing, suggests that they may have a therapeutic role in a range of psychiatric and neurological conditions due to their potential to stimulate neurogenesis, provoke neuroplastic changes and reduce neuroinflammation. This inevitably makes them interesting candidates for therapeutics in dementia. This mini-review will look at the basic science and current clinical evidence for the role of psychedelics in treating dementia, especially early AD, with a particular focus on micro-dosing of the classical psychedelics LSD and psilocybin.

Microdosing with psychedelics: what do we know?

August 1, 2020 / LSD, Microdosing, Mushrooms / Psilocybin, Papers, Psychology, Publications / By /

Abstract

The repeated use of small doses of psychedelics such as psilocybin and lsd over a period of time (microdosing, md) has gained popularity and scientific attention in recent years. Retrospective reports from users suggest clinical potential.<br/> AIM: To answer the question whether md with psychedelics could theoretically provide symptom relief for people with psychiatric disorders. <br/> METHOD: Investigate what the current evidence is about the effects of md with psychedelics on the behavioral level, psychological functioning and mental well-being. A search for relevant articles in PubMed and Medline databases (on January 10, 2020), which resulted in a total of 28 hits. After de-duplication, removal of irrelevant and addition of relevant articles, 23 articles were included.<br/> RESULTS: Most of the knowledge we have so far comes from uncontrolled online questionnaire studies in which users report retrospectively or keep diaries of the effects they experience during md. According to users, it leads to positive effects on mood, concentration, focus and productivity. Negative effects, including physical discomfort and increased fear, also seem to occur. The limited number of experimental studies in healthy people revealed that md has subtle effects on cognitive processes and brain connectivity.<br/> CONCLUSION: The findings of experimental studies in combination with the reports from users give cause for further investigation into the clinical potential of low-dose psychedelics in combating certain symptoms. More placebo-controlled studies are needed to provide clarity for who (age, diagnosis) md can be effective and for which (cognitive, emotional) processes.

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.
