Microdosing psychedelics delivers a measurable lift in mood and focus, but only on the day you take it. By the next morning, the benefits have evaporated. That's the core finding from a new international study tracking more than 1,400 people who microdose LSD or psilocybin. Researchers at the University of British Columbia Okanagan analyzed daily self-reports from participants across 49 countries, all logging their mental state each morning through the Microdose.me project.
