This article summarizes the main substrates of cannabis-associated psychoses. It first introduces an epistemological framework to support the existence of a specific "cannabis-associated psychosis" as a distinct nosological entity separate from idiopathic schizophrenia and other psychotic disorders. It then examines the main clinical features of cannabis-associated psychoses and presents their biological and genetic correlates.
Cannabis-associated psychosis is argued to be a distinct diagnostic category separate from schizophrenia and other psychotic disorders. The paper first establishes an epistemological basis for recognizing this specific condition. It then reviews the clinical features that characterize psychoses linked to cannabis use. Finally, it examines the biological and genetic factors that may underlie cannabis-associated psychosis.
