Development of scales to measure attitudes toward marijuana and marijuana users.

450 undergraduates participated in the 2-phase development of a 22-item marihuana attitude scale. The final form of the scale, partitioned into 3 factorially defined, mutually exclusive subscales, deals with (a) the psychological, physiological, and sociological effects of marihuana on users; (b) marihuana as a psychosocial panacea; and (c) liberal-conservative ambivalence toward the usage of marihuana.
