abstract="OBJECTIVEs To review the known impacts of recreational cannabis legalization on  mental health and substance use, in the context of recent changes in the status of  cannabis laws in Canada. <br><br>METHODS PubMed database was systematically searched using  various terms regarding mental health and cannabis legalization. Two independent  investigators then assessed a total of 272 titles and abstracts and 11 articles were  ultimately found eligible for review. <br><br>RESULTS Most studies measuring the impact of  legalization on cannabis use showed an increase in cannabis use after the  legalization. Moreover, no study demonstrated a reduction of cannabis use after  legalization of recreational cannabis. All three studies regarding health care  contacts demonstrated an increase in the number of cannabis-related emergency  department visits after cannabis legalization. Two studies revealed reduction of  perceived risks associated with cannabis after legalization, while another study  offered opposite results. To interpret these observational results accurately, we  also need to consider the long-term trends that prevailed before the changes in  cannabis laws. <br><br>CONCLUSIONS The quantity of evidence on the impacts of recreational  cannabis legalization on mental health and substance use is limited. Further  research is needed to strengthen these results and explore the effects of cannabis  legalization on other mental health issues such as psychosis.<p /> <p>Language: fr</p>",
