Indigenous theories of behavior are an integral part of any cultural knowledge system. While researchers in the field of implicit personality theory emphasize investigation of interrelationships of traits elicited in experimental settings, this analysis addresses naturally occurring typological assessments as "micro-theories" of context specific inferential relations between behaviors, rather than traits.
Thirty-seven typologies of cocaine users, obtained from consumers in Miami, are analyzed for common elements. Inferential relations between these elements reflect subcultural assumptions about the nature of cocaine use. These materials may be organized into a coherent schema which represents inferences used in making decisions about interactions with other users.
Two prototypical patterns emerge, the "cocaine junkie" and the "social-recreational user." Implicit in these types are assumptions about functional and dysfunctional use.
