Hallucinogen Use Disorder

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), describes and labels a number of mental health disorders under the category of Substance-Related Disorders. Common drugs of abuse have their own categories, and for hallucinogens, disorders are grouped around the use of PCP (phencyclidine; “angel dust”) or all other hallucinogens. Disorders are categorized based on problems associated with the intoxication itself, dependence and addiction issues, or related mental health complications. When hallucinogen use may kindle the emergence of a severe mood disorder, such as bipolar disorder, “onset during intoxication” or “with onset during withdrawal” may be assigned to the acute primary diagnosis. The DSM-5 categorizes hallucinogen intoxication into those with an associated mild, moderate, or severe use disorder or “without use disorder.”
