Epidemiology of Hallucinogen Microdosing Among Young Adults in the United States: A National Study
Drug and Alcohol Review February 26, 2026 Katherine M Keyes, Yvonne Terry-Mcelrath, Megan E Patrick
About 1 in 15 young adults in the United States reported microdosing hallucinogens in the past year, with 73% of those who used hallucinogens engaging in microdosing. Microdosing was strongly linked to other substance use: among microdosers, 72% reported 10 or more occasions of past-year alcohol use and 86% reported 3 or more occasions of past-year cannabis use. Odds ratios for other substance use among microdosers ranged from 2.53 for past-month cigarette use to 37.73 for heavy cannabis use. Few demographic differences emerged, though Black respondents were less likely to microdose than White respondents.
