Cognitive and Subjective Effects of Psilocybin Microdosing: Results from Two Double-Blind Placebo-Controlled Longitudinal Trials
These two randomised, double-blind, placebo-controlled trials (n=141) conducted in semi-naturalistic settings found that microdosing psilocybin truffles did not significantly affect cognitive control, memory, social cognition, subjective well-being, attention, mood, or self-reported cognitive flexibility compared to placebo. Initial effects in some domains did not remain significant after correcting for multiple comparisons.
