Study: Daily Cannabis Use Has No Effect on Brain Volume or Shape

A new study published in the Journal of Neuroscience has found that daily cannabis use has no effect on the volume or shape of an individual’s brain.brain

For the study, researchers at the University of Colorado “examined brain morphology in a sample of adult daily marijuana users versus nonusers and a sample of adolescent daily users versus nonusers. ”

Researchers “acquired high-resolution MRI scans, and investigated group differences in gray matter using voxel-based morphometry, surface-based morphometry, and shape analysis in structures suggested to be associated with marijuana use, as follows: the nucleus accumbens, amygdala, hippocampus, and cerebellum.”
