Poster Abstract
Cannabis use disorder (CUD) is recognized as a psychiatric condition characterized by persistent and problematic cannabis consumption that leads to marked functional impairment. Growing evidence suggests that chronic CUD exerts significant effects on executive functions such as inhibitory control, cognitive flexibility, goal-directed behavior, and decision-making. This literature review integrates findings from 25 studies focusing specifically on individuals with objectively diagnosed CUD to explore the effects on cognition in this patient population. Across studies, deficits in executive function are consistently observed, with adolescents and early-onset users demonstrating increased vulnerability. Neuroimaging studies reveal structural and functional alterations in the prefrontal cortex and hippocampal regions that correlate with cognitive impairment. Although partial recovery is possible following abstinence of cannabis use, executive dysfunction often persists, emphasizing the need for early detection, preventive interventions, and targeted cognitive rehabilitation strategies.

Cannabis Use Disorder and Executive Function - A Literature Review
