Article Synopsis
- * The OPUS study followed 578 individuals diagnosed with schizophrenia, reporting a 14.4% mortality rate over 20 years, primarily due to suicide.
- * Factors influencing lower mortality included employment and symptom remission, while substance use and chronic illnesses were linked to higher mortality risks, emphasizing a need for improved healthcare strategies.
Objective: Previous studies have suggested that infections increase the risk of schizophrenia. In this study, the authors aimed to investigate 1) whether infections increase the risk of substance-induced psychosis, and 2) whether infections increase the risk of converting from substance-induced psychosis to schizophrenia.
Methods: The study data were drawn from the combined nationwide Danish registers and included all people born in Denmark since 1981.
Background: Worldwide, cannabis is the most used illegal substance, and the use of cannabis has increased over the years. An increase in the level of tetrahydrocannabinol (THC) in cannabis has also been seen. It is currently unclear whether this has led to an increase in the incidence of cannabis-induced psychosis.

Method: All patient information was extracted from the Danish Civil Registration System and the Psychiatric Central Research Register. The study population included all persons who received a diagnosis of substance-induced psychosis between 1994 and 2014 (N=6,788); patients were followed until first occurrence of schizophrenia or bipolar disorder or until death, emigration, or August 2014.
