What is the relationship between smoking marijuana and the onset of psychosis?
Cannabis use can lead to various types of mental disorders, including psychotic disorders . The relationship between cannabis use and psychotic symptoms has been clearly described in numerous studies. Chronic cannabis users have a higher risk of developing both schizophrenia and other psychotic disorders.
First psychotic episodes and substance abuse
The earlier and more frequently cannabis use begins, the greater the risk. Some authors suggest that cannabis use may precipitate the onset of psychotic episodes in vulnerable individuals with a predisposing genetic predisposition. However, it is difficult to definitively establish a direct causal relationship between cannabis use and psychosis, as the development of psychotic disorders depends on multiple factors. Smoking cannabis may be a risk factor in people with a family history of psychiatric disorders.
