Study: Teens' Brains Affected by Alcohol, Not Marijuana

Safer than sex

A key part of the marijuana debate is the impact cannabis has on developing brains. And when reaching for a weekend tonic, teenagers have a choice — to reduce their brain tissues' health with alcohol, or to keep their brains unharmed with marijuana, according to a new study.

Researchers at the University of California, San Diego, scanned 92 adolescent brains before and after an 18-month period. Turns out, the teens who consumed five or more drinks twice a week had “reduced white matter brain tissue” — while the teens “who used the most marijuana did not show a change in brain tissue health,” the study found.

Party on.
