People who experience psychosis following the use of cannabis, hallucinogens, or amphetamines (known as substance-induced psychosis) may be at a greater risk of developing schizophrenia, according to ameta-analysis inSchizophrenia Bulletin. This risk was found to be only slightly less than that observed for patients who presented with other brief psychotic disorders.“These findings have important implications for mental health care and services. Substance-induced psychoses are common reasons for seeking mental health care,” wrote Grant Sara, M.B., of the University of Sydney and colleagues. “Yet despite this, people with substance-induced psychoses are of ten excluded from early psychosis services or assertive mental health care due to a perception that these are benign or self-limiting conditions.”Sara and colleagues searched MEDLINE, PsychINFO, and Embase for peer-reviewed, English-language studies published between 1980 and 2018 that looked at how often patients with substance-induced psychoses were later diagnosed with schizophrenia. They compared this group with those who had an initial diagnosis of “brief psychosis,” “atypical psychosis,” “schizophreniform psychosis,” or “psychosis not otherwise specified” who were later diagnosed with schizophrenia.The researchers identified 50 studies, which included more than 40,500 people. Of these studies, 25 looked at later diagnosis of schizophrenia among peo...
