Psychiatric Symptoms in Methamphetamine Users

Abstract

The Methamphetamine Treatment Project (MTP) offers the opportunity to examine co-occurring psychiatric conditions in a sample of 1016 methamphetamine users participating in a multisite outpatient treatment study between 1999-2001. Participants reported high levels of psychiatric symptoms, particularly depression and attempted suicide, but also anxiety and psychotic symptoms. They also reported high levels of problems controlling anger and violent behavior, with a correspondingly high frequency of assault and weapons charges. Findings continue to support the value of integrated treatment for co-occurring conditions, especially the importance of training counseling staff to handle psychotic symptoms when needed.
