Drug use among young adolescents has become an increasingly frequent behavior [1]. While numerous investigations have been undertaken to study the causal psychosocial factors of adolescent drug-taking, little attention has been given to the cognitive intentions, as opposed to behaviors, held by youth concerning the ingestion of psychoactive substances [2]. Among some young adolescents the absence of a personal source of supply for various chemicals may inhibit drug-taking whereas the youth is sure that he or she will initiate or escalate drug use when a supply becomes available at some time in the future. Similarly, for the youths who have not begun using drugs, knowledge of their intentions regarding psychoactive substance use may permit successful prediction of which adolescents will be attracted to subcultures that can supply the substance.
