Peer Cluster Theory: Drugs and the Adolescent

The authors review several theories advanced to explain adolescent drug use to provide background for describing peer cluster theory. Peer clusters, small subsets of peer groups, including pairs, dictate the shared beliefs, values, and behaviors that determine where, when, and with whom drugs are used and the role that drugs play in defining cluster membership. Peer cluster theory incorporates those psychosocial factors that promote or inoculate against drug use in youth.
