Altered cerebellar-cortical resting-state functional connectivity in cannabis users

Regular cannabis users show altered resting-state functional connectivity between the cerebellum and the cerebral cortex compared with non-using peers. The anterior cerebellum is hyperconnected to the posterior cingulate cortex, while most other cerebellar regions are hypoconnected to the cortex. These connectivity changes may affect behavior and cognition. No associations were found between cannabis use features—such as age of initiation or lifetime use—and the observed connectivity differences.
