AbstractIntroductionThis case series records a cohort of patients treated with transdermal buprenorphine patches as part of a buprenorphine microdose induction protocol to transition from methadone to buprenorphine in a community setting. This has historically been a difficult process to manage in community settings and this case series explored a method to gradually manage this in an...
Taking regular low doses of psychedelic drugs (microdosing) is a practice that has drawn recent scientific and media attention for its potential psychotherapeutic effects. Yet, controlled studies evaluating this practice have lagged. Here, we review recent evidence focusing on studies that were conducted with rigorous experimental control. Studies conducted under laboratory settings using...
Clinical trials of psychedelic compounds like psilocybin, lysergic acid diethylamide (LSD), and N,N-dimethyltrptamine (DMT) have forced a reconsideration of how nondrug factors, such as participant expectations, are measured and controlled in mental health research. As doses of these profoundly psychoactive substances increase, so does the difficulty in concealing the treatment condition in the...
Cytochrome P450 (CYP) enzymes play a central role in the elimination of approximately 80% of all clinically used drugs. Differences in CYP enzyme activity between individuals can contribute to interindividual variability in exposure and, therefore, treatment outcome. In vivo CYP enzyme activity could be determined with phenotyping. Currently, (sub)therapeutic doses are used for in vivo...
Background: Buprenorphine initiation in opioid-tolerant patients usually requires decreasing the total opioid intake per day due to its potential for precipitating withdrawal. However, this strategy may not be tolerated in patients who require higher amounts of opioids, such as those with cancer pain. Case Presentation: We utilized a buprenorphine microdosing strategy for a postoperative cancer...
Microdosing psychedelic drugs at a level below the threshold to induce hallucinations is an increasingly common lifestyle practice. However, the effects of microdosing on sleep have not been previously reported. Here, we report results from a Phase 1 randomized controlled trial in which 80 healthy adult male volunteers received a 6-week course of either LSD (10 µg) or placebo with doses...
Background and aim: In the present study, we focus on the relationship between state authenticity - the experience of being true to oneself in a particular moment - and microdosing - a practice that implies repeatedly ingesting very small doses of psychedelics that do not reach the threshold for perceptual alterations. We propose that microdosing could increase state authenticity through...
Abstract Microdosing psychedelics has garnered considerable attention within both nonprofessional circles and the scientific community in recent years. This method involves taking small, non-hallucinogenic doses of substances like LSD or psilocybin over weeks or months, purportedly to enhance specific behaviors, emotions, or address psychiatric conditions. Exploring these assertions is crucial...
Recent studies and anecdotal reports suggest that psychedelics can improve mood states, even at low doses. However, few placebo-controlled studies have examined the acute effects of low doses of LSD in individuals with psychiatric symptoms. In the current study, we examined the acute and sub-acute effect of a low dose of LSD (26 µg) on subjective effects and mood in volunteers with mild...
The practice of microdosing classic psychedelic drugs (e.g. LSD [lysergic acid diethylamide] and psilocybin) has not only become more commonplace, but has also been shown to have potential in treating various psychological impairments. Much is still unknown about how people who microdose psychedelic drugs learn the processes and protocols for microdosing. To uncover how people learn the various...
Abstract Introduction Maize production in smallholder farmers located in semiarid areas of Zimbabwe are mainly constrained by soil moisture and nutrient stress. Moisture stress is mainly due to erratic rainfall, high rates of evapotranspiration and limited knowledge of the use of in situ rainwater harvesting (IRWH) techniques. Tied ridges (TRs) are one of the best IRWH techniques which have...
Capillary dried blood spot (DBS) analysis coupled with multi-analyte steroid liquid chromatography mass spectrometry (LCMS) is attractive for field studies, home-based self-sampling as well as clinical trials by eliminating costly and laborious sample processing involving venipuncture and frozen storage/shipping while providing multiple steroid measurements from a single small sample. We...
In the present contribution, we examine the practice of microdosing psychedelics (microdosing) through textual analysis of the content produced by a dedicated online community, the r/microdosing subreddit. We collected a comprehensive dataset of publicly available submissions from this community and used structural topic modelling to identify and analyse the prevalent topics within the...
The therapeutic use of lysergic acid diethylamide (LSD) has resurfaced in the last decade, prompting further scientific investigation into its effectiveness in many animal models. Zebrafish (Danio rerio) are a popular model organism in medical sciences and are used to examine the repeated administration of pharmacological compounds. Previous zebrafish research found acute LSD altered behaviour...
Smallholder maize farmers are currently confronted with the arduous challenge of managing limited financial resources while incessantly facing the issue of land degradation. To address this issue, an alternative solution has been implemented to optimize the use of chemical fertilizer by adopting microdosing. This innovative system not only helps them enhance their agricultural productivity but...
An advanced cancer diagnosis can be associated with a significant profile of distress. Psychedelic compounds have shown clinically significant effects in the treatment of psychological distress in patients with advanced-stage cancer. Given the challenges of delivering timely and effective intervention in the advanced cancer context, it is possible that an alternative, more pragmatic, approach...
Despite common depictions in the media, there is little scientific evidence on microdosing psychedelic drugs. We assessed awareness, prevalence, and dosing practices of microdosing psychedelic drugs among young adults 18-22 years old from Southern California (2018-2019). We examined whether sociodemographic factors, personality traits, mental health, or other substance use behaviors were...
Microdosing ketamine is a novel antidepressant for treatment‐resistant depression. Traditional antidepressants, like selective serotonin reuptake inhibitors (SSRIs), inhibit serotonin reuptake, but it is not clear if ketamine shows a similar mechanism. Here, we tested the effects of feeding ketamine and SSRIs to Drosophila melanogaster larvae, which has a similar serotonin system to mammals and...
Introduction The practice of taking small, sub-hallucinogenic doses of psychedelics, known as microdosing, has exploded in popularity over the last decade. Users claim benefits ranging from improved mood and enhanced creativity to an increased sense of meaning and connectedness in life. While research on microdosing is still lagging behind the shift in public opinion, several papers have been...
ABSTRACT “Microdosing,” defined as the consumption of small, sub-hallucinogenic quantities of psychedelic drugs, has gained recent popularity. Microdosing is a relatively new concept, therefore no scientific recommendations exist on how to prepare and consume microdoses. Many consumers obtain microdosing information online. Few studies have investigated the content of this information; thus,...
