Variable activation in striatal subregions across components of a social influence task in young adult cannabis users

Abstract Introduction: Decades of research have demonstrated the importance of social influence in initiation and maintenance of drug use, but little is known about neural mechanisms underlying social influence in young adults who use recreational drugs.
