Teen Marijuana Use Affects Brain Regions Associated with Schizophrenia

Thursday, May 10th, 2012

New research has shown that adolescent marijuana use can cause changes in regions of the brain that are implicated in schizophrenia.  Researchers say that teen cannabis use can interact with a specific gene in a way that interferes with the brain’s pleasure and reward systems, and increases a person’s risk of the disease.

According to the lead study author, the study, “demonstrates how genetic, developmental and environmental factors interact to modulate brain function in schizophrenia and supports previous behavioral research which has shown the COMT gene to influence the effects of adolescent cannabis use on schizophrenia-related behaviors.”

The researchers hope that their findings will help mental health professionals better understand how marijuana affects teens’ “psychological and psychiatric well-being.”
