This study investigates changes in brain volume using MRI, finding scans of marijuana users demonstrate decreased activation in the frontal lobe and increased activity in a brain region rich in cannabis receptors.
Determining causality in research takes time, but recent research provides valuable insight into possible effects of marijuana use on brain structure and function.
