University Students’ Motives for Psilocybin Use: A Mixed-Methods Analysis

Motives are a highly influential force in substance use and vary depending on the substance or dose being used. Little research has compared motives across different doses of psilocybin. Psilocybin is often ingested in microdoses (0.1-0.4 g) or macrodoses (1 g+), each producing unique perceptual and mood effects. The current study examined whether motives for microdose and macrodose psilocybin use differ. An online survey was employed to examine differences in motives using an adapted Marijuana Motives Measure. A thematic analysis was conducted to further explore motives for each dose, and to determine if motives differ for initiating and continuing psilocybin use. As hypothesized, there were statistically significant differences in motives for microdose and macrodose use ( p
