This month, our team led by Maykel and Stéphanie published a systematic review summarizing all international scientific studies evaluating the efficacy of cannabidiol as an antipsychotic in people with psychotic disorders. Among the eight studies identified, there is insufficient evidence to conclude that the treatment was effective. In addition, the number of powerful and high-quality randomized studies is lacking. This is important since the antipsychotic virtues of cannabidiol have been widely disseminated in the media since the legalization of cannabis in Canada and the United States, and sometimes without proofs. This study therefore warns healthcare professionals and patients that the evidence is neither final nor rigorous enough to promote the use of this treatment, which is still experimental in the clinic, in psychotic patients.
