Among 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.
