Background: Cannabis is the most widely used illegal drug globally, with almost 200 million users in 2019. This use is associated with many negative health consequences and social problems, such as low school performance and other drug use. Cannabis use can be articularly harmful if it starts early, if it’s excessive or if it occurs associated with other forms of problematic behaviours. A lot of health behaviours, good or bad, emerge during adolescence and remain through the life course. Changing unhealthy behaviours in adolescence would significantly impact society, such as reducing the load of disease, injuries, and economic costs.

To compare and characterize the groups, descriptive and bivariate analyzes were undertaken, as well as their significance level. Results: Results show that most of the adolescents (81.8%) never consumed cannabis in their lifetime; 9.4% declared a consumption during their lifetime but not the past month; 6.6% used during the past month, non-daily; and 2.2% used (almost) daily during the past month.

In the case of social relationships and indicators of health and well-being, differences exist but are not as pronounced. Boys, older students and those who do not live with both parents ...
