Summary
AI-generated from the abstractAmong American adults who used MDMA in the past year, one in five (20%) reported at least one clinical feature of hallucinogen use disorder, compared with about one in six (16%) of users of other hallucinogens. The prevalence of hallucinogen abuse was 4.9%, subthreshold dependence 11.9%, and dependence 3.6% among MDMA users. Most individuals with hallucinogen abuse also showed subthreshold dependence, and most with dependence exhibited abuse. Subthreshold hallucinogen dependence is relatively common and represents a clinically important group that warrants further research and consideration in diagnostic classification systems.

Abstract
We investigated the prevalence, patterns, and correlates of past‐year DSM‐IV hallucinogen use disorders (HUDs) among past‐year users of MDMA and other hallucinogens from a sample of Americans 18 or older (n = 37,227). Users were categorized as MDMA users and other hallucinogen users. Overall, one in five (20%) MDMA users and about one in six (16%) other hallucinogen users reported at least one clinical feature of HUDs. Among MDMA users, prevalence of hallucinogen abuse, subthreshold dependence, and dependence was 4.9%, 11.9%, and 3.6%, respectively. The majority with hallucinogen abuse displayed subthreshold dependence. Most with hallucinogen dependence exhibited abuse. Subthreshold hallucinogen dependence is relatively prevalent and represents a clinically important subgroup that warrants future research and consideration in a major diagnostic classification system.
