New study determines psychedelic mushroom microdoses can improve mood, mental health

The latest study to examine how tiny amounts of psychedelics can impact mental health provides further evidence of the therapeutic potential of microdosing.

Published in Scientific Reports this week, the study followed 953 people taking regular small amounts of psilocybin and a second group of 180 people who were not microdosing. This research, led by University of British Columbia Okanagan’s Dr. Zach Walsh and doctoral student Joseph Rootman, is the latest study to come from the Microdose.me project.

For the 30-day study, participants were asked to complete a number of assessments that tapped into mental health symptomology, mood and measures of cognition. For example, a smartphone finger tap test was integrated into the study to measure psychomotor ability, which can be used as a marker for neurodegenerative disorders including Parkinson’s disease.

Those microdosing demonstrated greater improvements in mood, mental health and psychomotor ability over the one-month period, compared to non-microdosing peers who completed the same assessments.

“This is the largest longitudinal study of this kind to date of microdosing psilocybin, and one of the few studies to engage a control group,” says Dr. Walsh, who teaches in the Irving K. Barber Faculty of Arts and Social Sciences. “Our findings of improved mood and reduced symptoms of depression, anxiety and stress add to the growing conversation about the therapeutic potential of microdosing.”
