The use of psychoactive substances has always been looked as an important health problem, especially among adolescents. Yet the situation of cannabis remains singular, squeezed between a mass of scientific data describing its use by young people as worrisome and a certain level of social acceptability. Quebec youth deserve that we focus on this issue, especially since their cannabis use is one of the world¿s most frequent.

From a clinical and a public health perspective, it is precisely cannabis use trajectories at increased risk for health that need to be examined. Between early initiation, increasing consumption and concomitant use of several substances, when should we worry? Through a research program over the next four years, we will try to identify, using transversal and longitudinal data, which cannabis consumptions are worst. Specifically, we will study the trajectories of early consumption and its predictors, the patterns of cannabis use among youth from Nunavik, the multiple relationships existing between tobacco and cannabis, but also the capacity of professionals to identify consumption of cannabis related to mental health problems.

A broad understanding of the use of cannabis among youth from Quebec will better inform the community and public health stakeholders on possible harms associated with some behaviors. Aiming efficiency and reducing health care costs, we also hope to improve the detection of problematic situations and early intervention among young people in need of help.
