Prohibition of cannabis (marijuana) for the last 70 or so years led to many unfounded claims about it’s damaging effects. Claiming that it would “shrink your brain” was one that some of you may have heard.

In yet another study, that shrinking brain concept has again been proven to be completely false. Seventy-nine daily users and an equal number of non-users from adolescence through adulthood participated. The authors stated they matched for alcohol use as a confounding variable more carefully than previous studies.

High resolution MRI scans of the gray matter of 4 brain regions was carefully analyzed for the two groups. No statistically significant differences could be found in either size or shape of the brain regions between daily users and non-users.
