Course Description

The effects of regular marijuana use on brain integrity and cognition have important implications for policy makers considering medical and recreational marijuana laws. Nevertheless, the impact of marijuana on the brain remains a point of debate. While frequency and duration of use, duration of abstinence, and cannabinoid content influence the impact of marijuana on the human brain, it has been reported that age of initiation and high levels of consumption may be especially significant factors associated with brain alterations related to marijuana use. Findings suggest that age of first use of marijuana may be associated with altered prefrontal cortical development in adolescents and may lead to disruptions in normal developmental trajectories of cortical circuits, which underscores the importance of preventing marijuana use in children and adolescents. This course examines multimodal magnetic resonance imaging data (structural MRI, diffusion tensor MRI, functional MRI and magnetic resonance spectroscopy), as well as clinical and neuropsychological results acquired in adolescent and young adult marijuana users. It discusses the relationship between age of first marijuana use and total lifetime marijuana use and demonstrates the association of different patterns of functional connectivity, morphometric measures and metabolite levels with risk and exposure.
