With marijuana legalization on the rise, an increasing number of studies are exploring the drug’s potential harms and benefits. However, a new study suggests that when it comes to brain health, alcohol is more damaging.
Scientists at the University of Colorado Boulder conducted a review of existing imaging data that looked at the effects of alcohol and marijuana, or cannabis, on the brain.
Their findings linked alcohol consumption with long-term changes to the structure of white matter and gray matter in the brain.
The use of marijuana, however, seemed to have no significant long-term effects on brain structure.
