Harm-to-others including injuries from violence have nevertheless unfortunately largely overlooked. While studies remain heterogeneous, there is meta-analytical evidence pointing an association. The aims this focused review are two-fold: (I) meta-analyses association between violence; (II) provide overview possible mechanisms relating use to violence. First, in youths, intimate partners individuals severe mental disorders shown that global moderate violence, which stronger latter more at-risk population. Preliminary data even highlighted potential dose-response relationship larger frequent users. Although importance, subject remained essentially forgotten as health concern. literature remains inconclusive, suggested increases following policies. This may increase violent outcomes if effect directly related by means its psychophysiological modifications. However, for moment, associating be clearly resolved. Considering recency policy changes cannabis, further methodologically sound research using longitudinal designs should examine different forms trends emerge, while evaluating confounding factors (e.g. other substance use). In addition, evidence-based associated measures must taken mitigate risks.
