Cannabis use and age at onset of schizophrenia.

Cannabis use may hasten the onset of schizophrenia.

​This study assessed the effect of cannabis usage on the age of onset of schizophrenia. Researchers compared the age of diagnosis of schizophrenia between users and non-users of cannabis. 

Researchers noticed that schizophrenia occurred at a earlier age in cannabis users than in non users. Schizophrenia was found to be diagnosed much younger in male cannabis-using patients than in their female counterparts in this study. The results of this study show that cannabis use may accelerate the development of schizophrenia.
