Salience, Sensemaking, and Setting in Psilocybin Microdosing: Methodological Lessons and Preliminary Findings of a Mixed Method Qualitative Study

Introduction

Research on classical psychedelics restarted in earnest from the 1990s after a long hiatus, driven by findings in psychedelic-assisted psychotherapy and by anecdotal and survey reports suggesting benefits for cognition, creativity, mindfulness and several psychiatric conditions. One commonly reported pattern of use is microdosing, defined as repeated use of sub-threshold doses intended to avoid overt psychedelic effects, but there is no consensus on what constitutes a microdose and observational reports are heterogeneous. The field faces substantial methodological challenges, including legal constraints, expectancy effects and difficulties with blinding, and recent critiques have emphasised non-representative sampling and unclear boundaries between therapeutic process and adverse events. Oblak and colleagues present a pilot, proof-of-principle qualitative study that aims to characterise the lived experience of people who self-administer psilocybin microdoses in naturalistic settings. The study combines momentary ecological assessment (repeated in-the-moment sampling) with detailed phenomenological interviews to examine both moment-to-moment experience and retrospective sensemaking, and to derive methodological lessons for larger mixed-methods investigations and harm-mitigation strategies.
