The role of personality in the onset of alcohol, tobacco and cannabis use during adolescence.

Abstract

Some studies have shown that personality, specifically low conscientiousness (C), low agreeableness (A) and extraversion (E), are involved in substance use . T he purpose of this study is to determine which five - factor model personality characteristics are related to alcohol, tobacco and cannabis use and study thus relationship in detail during the transition from early adolescence to adolescence . 866 students from IES Bovalar participated in this study answering the questionnaires JSNEO - S and CODIS . The Pearson correlation analyses showed that extraversion was associated with alcohol and tobacco mainly at 14 - 15 years probably because at these ages substance consumption is highly recreational and social . Low agreeableness and low conscientiousness, whom predispose antinormative behavior, are related to early substance use . Finally, cannabis use is related to extraversion and low agreeableness mainly at 14 - 15 years . This would indicate that cannabis has a social and recreational component, but at the same time, its consumption is still considered antinormative and transgressive .
