PERSONALITY AND SUBSTANCE USE

Abstract

The purpose of this study is, first and foremost, to investigate whether there is a link between a personality trait (impulsivity) and substance use and, also to investigate whether there are significant differences between impulsivity levels and substance use levels. Participants completed online a google form that included demographic questions, a questionnaire that measures the level of substance use and one that measures the level of impulsivity. The results showed that the level of impulsivity correlated positively with the level of tobacco consumption, but also with the level of alcohol consumption. In addition, significant differences were found in impulsivity between the 3 levels of cannabis use (low consumption, moderate consumption, high consumption). The results suggest that there is an association between certain facets of impulsivity and tobacco, alcohol and cannabis use.

Key words: impulsivity, consumption, substance, tobacco, alcohol, cannabis.
