Young adults who regularly use marijuana display altered brain activation patterns during social exclusion, research indicates. In a recent study, participants played a computerized game of catch while undergoing a non-invasive brain scan. They recruited 42 young adults (ages 18-25), about half of whom regularly used marijuana. Unknown to the study participants, the other ‘players’ in the game were computers and were programmed to exclude them for a portion of the game.

"In this study, during peer rejection, young adult marijuana users had reduced activation in the insula, a brain region usually active during social rejection," said Gilman. "This may reflect impaired processing of social information in marijuana users. Reduced activity in the insula to peer rejection could indicate that marijuana users are less conscious of social norms, or have reduced capacity to reflect on or react to negative social situations."

"The results suggest that the cannabis users are less sensitive to exclusion than non-drug using individuals," added Dr. Cameron Carter, Editor of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. "The study does not address whether this impaired processing is a core trait of cannabis users or a byproduct of the drug use itself."

So, ah…what this boils down to, is that they have now scientifically proven that stoners don’t give a fuck whether peer constructions like them or not, I guess.

Shit, I could’a told them that for free.
