12-month prevalence of other hallucinogen use disorder is similar for Native Americans
and Alaska Natives, whites, and Hispanics (a ll 0.2%) but somewhat lower for Asian Amer-
icans and Pacific Islanders (0.07%) and Africa n Americans (0.03%). Past-year prevalence is
higher in clinical samples (e.g., 19% in ad olescents in treatment) . Among individuals cur-
rently using hallucinogens in the general popu lation, 7.8% (adult) to 17% (adolescent) had
a problematic pattern of use that met criteria  for past-year other hallucinogen use disorder.
Among select groups of individuals who use hallucinogens (e.g., recent heavy ecstasy
use), 73.5% of adults and 77% of adolescents have a problematic pattern of use that may
meet other hallucinogen use disorder criteria.
