Hallucinogen-Induced Psychotic Disorder (HIPD)

Hallucinogen-Induced Psychotic Disorder (HIPD) is most commonly caused by LSD and other hallucinogens. It is a psychotic reaction to the drug that persists after the drug has run its course. People who have taken LSD will continue to feel strange days, weeks, or months after they have taken it. They experience changes in thinking and feeling that are commonly known as ‘psychosis.’

Symptoms of psychosis include:

  • paranoia - extreme fear and anxiety

  • hallucinations - seeing things that aren’t there

  • delusions - believing things that aren’t true

  • changes in thinking

It is important to call 911 or go to your local emergency room if you believe you may have HIPD. Explain to them that you have taken LSD and need to go to the hospital. They will send an ambulance to pick you up. At the hospital, explain to them what happened and they will give you lifesaving antipsychotic medication that will cure your HIPD.

Left untreated, Hallucinogen-Induced Psychotic Disorder can continue for weeks, months, or years. Left untreated, HIPD sufferers can attempt suicide during their psychotic state. LSD was originally categorized as a Schedule I controlled substance, the most restricted, because of the suicide of Diane Linkletter 6 months after she took LSD.

HIPD can happen from other hallucinogens such as psilocybin, mescaline, or DMT, but most commonly occurs with LSD.

Hallucinogen-Induced Psychotic Disorder (HIPD) is also commonly known as hallucinogen-induced psychosis or psychedelic-induced psychosis. Hallucinogen-Induced Psychotic Disorder has the ICD-11 code of 6C49.5. It is also included in the general term, substance-induced psychosis.
