Project title: Proventure. Cannabis use and psychotic experiences in adolescents: A longitudinal brain imaging study

Study levels: MSc and PhD

Principal investigators: Dr Patricia Conrod, Dr Stéphane Potvin

Project duration: 2-4 years

Available positions: 2

Start date: Between January 2023 and December 2023

Overview of the research group

Substance use disorders are widespread, with their first symptoms appearing in adolescence and a high rate of comorbidity with other mental disorders. Dr. Conrod’s lab is studying the development of these disorders and their risk factors using multimodal longitudinal research designs. Dr. Conrod’s research has shown that substance use behaviors can be predicted by a combination of psychological, genetic, and neurocognitive factors, which can then be targeted in preventive psychosocial interventions. These findings have led to the development of an intervention program that has proven effective in preventing substance abuse and mental health problems in high-risk youth.

Research project description

ProVenture is a large longitudinal study (4 years) following 120 youths annually. This study aims to better understand the impact of cannabis use on the structural and functional development of the brain, with particular attention to the evolution of psychotic symptoms. We use a variety of tests including magnetic resonance imaging (MRI), clinical interview, neurocognitive tests, and questionnaires (see:
