Summary
Human studies have expanded insight about the lasting effects of adolescent cannabis use documenting structural and functional alterations in frontal and limbic regions of the brain, potentially relevant to behavioural vulnerability. Functional neuroimaging indicates that cannabis experience during adolescence is associated with perturbations in regions relevant to cognitive function such as working memory, attention, inhibitory control, and decision-making. Inconsistencies evident in the literature likely relate to variability in amount and frequency of cannabis use, potency, psychiatric comorbidity, and polysubstance use. Translational pre-clinical models help to elucidate how these factors contribute to protracted behavioural vulnerability of adolescent cannabis exposure.
