The attribution of the causality regarding the quality of life in a community and the security within a community differs between user and non-user groups of illegal drugs. An attribution theoretical model based on intergroup relations presents a new conceptualization of dyadic relations as the Covalent Security Attribution model. The Covalent Security Attribution model of user and non-user intergroup dynamics provides an exegesis of group cognitive consistency and the attribution process. This inquiry provides a heuristic examination of the Covalent Security Attribution model of adolescent substance abuse.The etiology of adolescent substance abuse remains a perplexing area of inquiry. Adolescent substance abuse has a significant impact on the health and well-being of all communities. The complex nature of the interaction between user and nonuser groups in a community remains a challenge for therapeutic programs and prevention research professionals. The attribution of the causality regarding the perceived quality of community and security within the community differs between user and nonuser groups of illegal drugs. This inquiry proposes a model of adolescent substance abuse behavior. The Covalent Security Attribution model (CSA) is based on the works ). The nexus of an attribution theoretical model proposed by Weiner (1995) and intergroup relations (McDonald, 1995;Tajfel, 1972Tajfel, , 1973 is developed to reveal the conceptualization of the Covalent Security Attribution model. The development of this model is based on extensive research on substance abuse in the areas of sociology, social psychology, family therapy, and clinical psychology. The examination of user and non-user intergroup dynamics reveals significant differences in each SOCIAL
