Is Teen Drug Use Related to Brain Size?
Article from NIDA for Teens
From the article:
"Researchers found that higher levels of alcohol, cigarette, and marijuana use before age 19 correlated with significantly less “gray matter” in two brain areas at age 25."
Less gray matter in a brain area could mean it contains fewer nerve cells (neurons), which might reduce that brain area’s ability to function in a healthy way.
