Undergraduate marijuana use as related to internal sensation novelty seeking and openness to experience.

Used 148 male and 130 female college students as Ss and replicated and expanded upon previous findings in marijuana personality research. It was found that the greater the self-reported frequency of marijuana use across Ss, the higher the cores on creativity and adventuresomeness tests tended to be and the lower the scores on authoritarianism tended to be. Males were more frequent users than females; Jews more frequent users than Protestants or Catholics. A new variable, internal sensation novelty seeking, was found to be correlated with self-reported frequency of marijuana use. Self-reported length of marijuana use was not related to any of the major variables, with the singular exception that after 2 years of use, expressed boredom with the environment decreased significantly.
