nonmedical cannabis is now legal in Canada, it is important to understand the complex relationship between perceptions of risk, problematic cannabis use and mental health among young adults.Objectives:To assess whether perceptions of risk associated with cannabis relates to cannabis use among young adults. Moreover, we explored whether current symptoms of anxiety were also related to problematic use, and the role of gender in this relationship.Methods:Self-report surveys were completed by 1043 Carleton University students. Students completed several questionnaires assessing perceptions of risk associated with cannabis use, and cannabis use and anxiety symptoms.Results:Males were significantly more likely to rate some of the harms associated with cannabis use as less risky, and reported higher rates of cannabis use. We also found that problematic cannabis use was positively related to anxiety symptoms, and this relationship was moderated by gender such that greater cannabis use related to higher anxiety scores more strongly among females.Conclusions:Our study yields valuable information regarding how Canadian youth perceive the risks associated with cannabis use; critically, males are more likely to perceive minimal risk with use and are also more likely to use problematically. By contrast, cannabis use is more strongly related to anxiety among females. These results have important implications for education and outreach campaigns associated with the legalization of cannabis and cannabis products in Canada.
