Cannabis has been implicated as a risk factor for the development of schizophrenia, however, but the pathway of cannabis causing psychosis is not well understood. It appears that cannabis does not cause any structural changes per say but deficits in areas of the brain responsible for memory and emotion do show some changes. Recent studies suggest that cannabinoids such as CB1 have a pharmacological profile similar to that of atypical antipsychotic drugs. This mechanisms may involve dopamine, GABA, and glutamate neurotransmission; It is still not known if these changes are transitory or permanent, and whether or not they contribute to …

Pathways To Psychosis In Cannabis Abuse, Amresh Srivastava

Cannabis has been implicated as a risk factor for the development of schizophrenia, but the exact biological mechanisms remain unclear. In this review, we attempt to understand the neurobiological pathways that link cannabis use to schizophrenia. This has been an area of great debate; despite similarities between cannabis users and schizophrenia patients, the evidence is not sufficient to establish cause-and-effect. There have been advances in the understanding of the mechanisms of cannabis dependence as well as the role of the cannabinoid system in the development of psychosis and schizophrenia. The neurobiological mechanisms associated with the development of psychosis and effects …
