This study presents an analysis of the process of becoming a marijuana dealer. It is only through an understanding of this process that the problem of marijuana can be completely understood. The process of becoming a dealer is seen as a process consisting of two parts: (1) the development of the external relationships which allow entrance into the marijuana-using groups; and (2) the rationalizing of the internal norms and goals of the larger society to those of a marijuana dealer. The social controls of society that prohibit marijuana use are outlined, and focus of the study is directed at the social processes that take place in the development of a dealer. There could be a pre-disposition in the personality of the people who become dealers, but unless this potential is subjected to the processes described in this paper, the potential will never be realized.
