A Critical Systematic Review of Evidence for Cannabinoids in the Treatment of Schizophrenia

Psychiatric Annals

“Cannabinoids have an emerging evidence base as an effective treatment option in a number of medical conditions, including anorexia and intractable vomiting.

It is well known that patients with schizophrenia are more likely to use cannabis; it has also been argued that this could be a way of self-treating adverse side effects (secondary to antipsychotics) in a group of people with schizophrenia. Therefore, studies have attempted to examine the use of cannabinoids in schizophrenia.

Given the recent interest in the use of cannabinoids in general and the ensuing ethical debates, we systematically review the available literature on the use of four cannabinoids, namely delta-9-tetrahydrocannabinol, dronabinol, rimonabant, and cannabidiol, in the management of schizophrenia. We also offer suggestions for future research in this area.”
