Abstract
This study, based on data (N =134) obtained by self-administered questionnaires, examines the extent marijuana users can be sexually differentiated regarding usage patterns, acquisition, distribution, effects on social relationships, and other activities. Generally, no significant sexual variations were observed except that males were more likely to personally purchase, to have sold marijuana, to bring it along when visiting friends, to hesitate having friends be their only source, and to be concerned about other users knowing of their use. It is suggested that sexual differentiation may reflect lesser involvement and that it may reduce as higher level users are examined.
