Are there other Hallucinogen Use Disorders?

Yes. A diagnosis of “other hallucinogen use disorder” is made when there is a problematic pattern of hallucinogen use (other than phencyclidine) that causes significant impairment or distress, as demonstrated by at least two of the following factors occurring within a 12-month period:

  • The hallucinogen is often taken in larger amounts or over a longer period than was intended.
  • There is a persistent desire or unsuccessful efforts to cut down or control hallucinogen use.
  • A great deal of time is spent trying to obtain the hallucinogen or recover from its effects.
  • Person has a craving or strong desire to use the hallucinogen.
  • Recurrent hallucinogen use results in a failure to fulfill major obligations at work, school, or home (e.g., repeated absences from work or poor work performance related to hallucinogen use; suspensions or expulsions from school; neglect of children or household).
  • Hallucinogen use continues despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the hallucinogen (e.g., arguments with a spouse about consequences of intoxication; physical fights).
  • Important social, occupational, or recreational activities are given up or reduced because of hallucinogen use.
  • Recurrent hallucinogen use takes place in situations where it is physically hazardous (e.g., driving a car or operating a machine)
  • Hallucinogen use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to be caused or exacerbated by the drug.
  • Tolerance has been built up, as defined as either of the following:
    • A need for markedly increased amounts of phencyclidine to achieve intoxication or desired effect.
    • A markedly diminished effect with continued use of the same amount of phencyclidine.
