Background: Traumatic brain injury (TBI) can result in prolonged post-concussive syndrome and chronic hypoxic-ischemic brain injury (HIBI) sequelae remains therapeutically challenging with the persistence of significant neurological and cognitive impairments. While conventional treatments often provide limited relief, emerging research explores alternative therapeutic interventions, including...
Expanded use of buprenorphine-naloxone use, particularly for marginalized communities, such as the unhoused, is an established priority. Unfortunately, due to fear of the precipitation of opioid withdrawal, this goal remains unmet. In response, microdosing methods during the initial week of treatment do not require opioid abstinence and do not precipitate withdrawal. This review establishes the...
An increasing number of U.S. states are implementing or considering alternative policies to the prohibition of some psychedelic substances for nonclinical purposes. The authors present new data and analysis to inform these discussions with survey results on the use of 11 psychedelic substances and detailed information about the prevalence of microdosing (i.e., taking a fraction of a full dose,...
Purpose Current laws prohibiting access to illicit drugs contribute to drug harms as manufacturers and distributors of illicit substances have variable influence over drug supply and quality. Legislation introduced in New Zealand (NZ) in 2021 aimed to address such harm by enabling licenced drug checking providers to directly analyse samples from consumers. This paper aims to detail the use of...
ABSTRACT: The recent resolution of semaglutide and tirzepatide shortages by the US Food and Drug Administration (FDA) has fundamentally altered the regulatory landscape for compounded obesity medications. Despite recent federal pricing agreements to reduce GLP-1 costs, ongoing affordability barriers continue to drive patient desperation, fueling a shift toward unsupervised strategies such as...
Electroencephalographic (EEG) microstates provide a compact framework for characterizing the temporal organization of large-scale brain activity, yet their sensitivity to altered brain states remains insufficiently explored. In this study, we applied broadband and frequency-resolved EEG microstate analysis to resting-state EEG data from two publicly available datasets acquired under markedly...
The development of lung-directed therapeutics is limited by poor translational fidelity between preclinical models and early-phase clinical trials. We report a first-in-human Phase 0 intratarget microdosing study demonstrating the feasibility of intrapulmonary delivery and pharmacological interrogation of a novel inflammasome inhibitor. A 100 μg microdose of ADS032, a dual NLRP1/NLRP3...
This study compared the effects of low-frequency flywheel resistance training (FRT, 1 session/week) and microdosing FRT (5 sessions/week) on muscle architecture, strength, and vertical jump performance in active individuals. Thirty participants were randomized into a microdosing group (MDG, n = 15) or a control group (CG, n = 15). Both groups completed equalized weekly training volumes (30 sets...
IntroductionMicrodosing involves consuming low doses of psychoactive substances, typically between 1/5th and 1/20th of a recreational dose. Despite increasing public attention to cannabis and psychedelics amid evolving drug policies, epidemiologic data on microdosing remain limited.MethodsA cross-sectional, web-based survey (Characterizing the Epidemiology of Cannabidiol Use Survey) of 1,523...

Fibromyalgia (FM) is a chronic pain condition characterized by widespread pain, fatigue, sleep disturbances, and mood changes. Available treatments often provide limited relief, highlighting the need for new therapeutic approaches. Repurposing offers a faster and more cost-effective path to innovation. Lysergic acid diethylamide (LSD), historically known for its psychedelic effects, has...
Purpose This study aims to present a lightweight digital twin for top-of-rail (TOR) friction management that relies only on physics and closed-loop control; no artificial “friction floor.” Design/methodology/approach The twin couples along-track film transport (diffusion; diurnal evaporation, curvature-weighted axle consumption, optional rain wash-off) with a monotone, saturating µ(h) map and a...
Abstract Introduction Difficult to treat wounds, such as burns and chronic wounds, constitute a continuous challenge. One current trend is towards developing dressings that allow for targeted delivery of active substances. However, some promising substances are hormones and while exerting positive effects on wound healing, systemic distribution may have detrimental effects and are to be...
At least 8.4 million US adults have microdosed psilocybin in their lifetime. Those who have used psilocybin within the past year are more likely to report microdosing the last time they used than those who have used psilocybin more than one year ago; however, approximately 15% respondents who used psilocybin in their lifetime were unsure whether they microdosed the last time they used....
INTRODUCTION: This paper aimed to determine the prevalence, demographic correlates and co-occurring substance use patterns of hallucinogen microdosing among young adults in the United States. METHODS: Design: Cross-sectional analysis of data from a nationally-representative cohort study collected in 2022-2023. SETTING: United States. PARTICIPANTS: Sample of 3094 young adults aged 19-30 years in...
Abstract IMPORTANCE Microdosing psilocybin may be a novel treatment for major depressive disorder (MDD). OBJECTIVE Assessing the antidepressant effects and safety of repeated low doses of psilocybin in participants diagnosed with MDD. DESIGN This was a Phase II, randomized, double-blind, placebo-controlled clinical trial. SETTING The trial was conducted from July 2022 to December 2024 at two...
Results suggest short-term improvements in mood following microdosed LSD in people with depression, warranting confirmation in controlled trials. It provides the pharmacokinetic parameters of 8 μg of LSD in a sample of people with depression and indicates no tolerance or sensitisation to repeated microdoses of LSD, despite incremental dose titration.
BACKGROUND: Major depressive disorder (MDD) is the leading cause of disability worldwide, affecting roughly 322 million people. Recently, doses of psilocybin have shown promise in treating mood disorders, sparking interest in other dosing practices. According to anecdotal reports and observational studies, microdosing psilocybin yields benefits to mental health; however, rigorously controlled...
Microdosing is a novel approach to the consumption of classic psychedelic substances, such as LSD (lysergic acid diethylamide) and psilocybin that emerged in recent years. Unlike traditional illicit substance use, which often seeks euphoric experiences, microdosing deliberately avoids such effects in pursuit of self-enhancement. This practice has grown in popularity likely due to the perceived...
Additive manufacturing offers unprecedented opportunities for personalized medicine, but most pharmaceutical printing platforms are optimized for milligram-range doses, limiting their suitability for microdosing. This work introduces a novel liquid deposition approach using a modified technical pen integrated into a pharmaceutical printer. The gravity-driven mechanism enabled precise microscale...
