A systematic review of medical students' and professionals' attitudes and knowledge regarding medical cannabis.

The finding that both medical students' and professionals' acceptance of MC has significantly increased in recent decades-in conjunction with their consistent, strong desire for more educational material-suggests that the medical community should prioritize the development of MC educational programs. MC is far more likely to succeed as a safe and viable therapy if the medical professionals who administer it are well-trained and confident regarding its clinical effects. Limitations include a lack of covariate-based analyses and the exclusion of studies published after the literature search was performed (June 2019). Future research should analyze studies published post-2019 to draw temporal comparisons and should investigate the effect of numerous covariates (e.g., gender, religiosity, prior cannabis use) as newer studies gather data on these factors [PROSPERO Registration: CRD42020204382].
