Introduction: Drug use is a significant health, economic and social concern globally. Research indicates that personality traits are crucial in explaining drug use. This paper contributes to the expanding literature by exploring how personality traits at age 10 affect the likelihood of having used any drug at age 30. Methods: Data were extracted from the British Cohort Study 1970. The Big Five dimensions were derived by aggregating items related to distinct traits. Furthermore, probit regression analysis was conducted to ascertain the relationship between personality traits at age 10 and drug use by age 30. Results: Children with low levels of conscientiousness, or agreeableness; or high levels of extraversion, or internal locus of control at the age of 10 are more likely to use any drug in adulthood. In addition, significant differences were observed across gender and types of drugs. Conclusions: These findings suggest that early personality traits play a pivotal role in predicting the likelihood of drug use in adulthood. The results interest policymakers, as they could guide the implementation of personality-targeted interventions to mitigate the adverse effects of specific personality traits. For instance, emotional regulation training could benefit children with low conscientiousness; while stimulating activities such as sports, creative arts, or music could engage children with high extraversion.
