Smoking pot can be safer for a teen’s brain tissue than drinking alcohol — that’s according to a new study by researchers at UC San Diego.


According to American Live Wire, researchers scanned the brains of 92 individuals between the ages of 15 and 20 years old, who already consumed marijuana and alcohol. During the study, which lasted 18 months, half of the teenagers minimized their consumption; while the other half increased their consumption of both substances.



According to MSN:
The researchers  scanned their brains before and after the study, looking to find the different ways alcohol and marijuana affect white brain matter. And they found...


“The before and after brain scans showed the booze drinkers showed reduced white matter, that could mean a decline in memory, attention and decision making. While the pot smokers showed no change in brain tissue.”


The damage occurs because white matter brain tissue develops throughout adolescence and into a person's 20s. But according to The Huffington Post, researches still aren’t sure why alcohol had an effect but marijuana didn’t.


“[Researchers said] study results cannot be considered definitive without more research. … they do not know if the reduced brain tissue health is permanent. But…because white matter brain tissue development may be the basis for greater self-control, researchers hope to be able to eventually use brain scans like those in this study to predict young individuals' likelihood of substance abuse.”


While this latest study only examines marijuana's effect on physical brain tissue, there was another study earlier this year showing that frequent marijuana users under 18 risk a long-term drop in their IQ.
