Hallucinogen use disorder is the DSM-5 diagnosis for a problematic pattern of hallucinogen use, covering substances like LSD and psilocybin.[1] Most classic hallucinogens do not cause physical dependence, so the disorder is driven by psychological dependence and complications such as hallucinogen persisting perception disorder (HPPD). This page explains both and points to treatment.

Hallucinogen use disorder is the DSM-5 diagnosis for problematic use of classic hallucinogens such as LSD, psilocybin (mushrooms), mescaline, and DMT. Unlike opioids or alcohol, these substances generally do not produce significant physical withdrawal, so the disorder is defined largely by psychological dependence, loss of control, and continued use despite harm.[2]
Risk often centers less on physical dependence and more on the consequences of use: dangerous behavior during intoxication, worsening of underlying mental health conditions, and a specific complication called HPPD. Hallucinogen Persisting Perception Disorder is a condition where visual changes, like halos, trails, or sudden flashbacks, persist long after hallucinogen use has stopped.[3]
Because misuse is frequently part of a wider polysubstance pattern, a full assessment matters. Our team can help you understand the whole picture.

The DSM-5 applies the standard substance-use-disorder criteria, but for hallucinogens the clinically distinctive issues are:
HPPD in particular can be distressing and benefits from clinical support, even after use has stopped.

It is the DSM-5 diagnosis for a problematic pattern of use of classic hallucinogens such as LSD, psilocybin, mescaline, and DMT. Because these substances cause little physical dependence, the disorder is defined largely by psychological dependence and continued use despite harm.
Classic hallucinogens generally do not produce significant physical dependence or a physical withdrawal syndrome. The risk is psychological dependence, dangerous behavior during intoxication, worsened mental health, and the complication called HPPD.
LSD does not cause physical dependence, but some people use it compulsively despite harm, which meets the definition of a use disorder. LSD can also worsen underlying anxiety or psychosis and contribute to HPPD.
Yes. While physical dependence is minimal, compulsive use, loss of control, and continued use despite harm can occur and are often part of a wider polysubstance pattern that warrants a full assessment.
Treatment is behavioral: cognitive behavioral therapy, support for any HPPD distress, and integrated dual diagnosis care for co-occurring anxiety, depression, or psychosis. A full assessment matters because misuse is often part of polysubstance use.
The terms overlap. Classic hallucinogens (LSD, psilocybin) and psychedelics are closely related, while substances like MDMA and ketamine have distinct pharmacology.
