This study is a qualitative examination of twenty current and former users of marijuana, using in-depth interviews as the units of analysis. The relationship between the participants’ perceived costs and rewards, type and amount of linguistic accounts used, as well as frequency of use are explored using Homans' exchange theory and Lyman and Scott’s theory of accounts. Reasons for continuation, regulation, and cessation of use are also studied. It is found that the participants use marijuana for a varied amount of reasons; these reasons directly influence how they account for their behavior as well as their frequency of use, particularly whether or not they use marijuana on a daily basis.
