Becoming a Marijuana User

The use of marijuana is and has been the focus of a good deal of attention on the part of both scientists and laymen. One of the major problems students of the practice have addressed themselves to has been the identification of those individual psychological traits which differentiate marijuana users from nonusers and which are assumed to account for the use of the drug. That approach, common in the study of behavior categorized as deviant, is based on the premise that the presence of a given kind of behavior in an individual can best be explained as the result of some trait which predisposes or motivates him to engage in the behavior.
