Abstract excerpt

Largest pre-registered self-blinding study of psychedelic microdosing to date. 191 participants who were already planning to microdose were randomized to placebo, microdose, or alternating-dose protocols using opaque capsules they prepared themselves. Mood and cognitive outcomes were measured at 4 weeks. Participants who believed they had microdosed reported substantial improvements regardless of what was actually in the capsule; no significant differences were found between actual microdose and placebo arms. The findings suggest much of the previously-reported microdosing benefits may be placebo-mediated.
