Study: Dangers for casual pot smokers Published: April 16, 2014

Young, casual marijuana smokers experience potentially harmful changes to their brains, with the drug altering regions of the mind related to motivation and emotion, according to Reuters.

A new study to be published on Wednesday in the Journal of Neuroscience differs from many other pot-related research projects that are focused on chronic, heavy users of cannabis.

The collaborative effort between Northwestern University's medical school, Massachusetts General Hospital and Harvard Medical School showed a direct correlation between the number of times users smoked and abnormalities in the brain, Reuters reports.
