Hallucinogen Use Disorder

Hallucinogen use disorder is characterized by recurrent use of hallucinogenic substances resulting in clinically significant distress or functional impairment. Etiologies include psychosocial factors, peer influence, genetic predisposition, and environmental accessibility. Patients may present with perceptual disturbances, cognitive impairment, social withdrawal, and risky behaviors. Diagnosis is based on DSM-5 criteria for substance use disorders, including impaired control, social impairment, and risky use. Management involves cessation support, cognitive-behavioral therapy, motivational interviewing, and monitoring for medical or psychiatric complications. Prognosis depends on sustained abstinence and engagement in behavioral interventions.
