PERCEPTION OF RISK AND DRIVING UNDER THE EFFECTS OF ALCOHOL AND MARIJUANA ON UNIVERSITY STUDENTS IN A MULTICENTER STUDY: COLOMBIA

ABSTRACT Objective: analyze the relationship between the perception of risk and the behavior of driving under the influence of alcohol or marijuana or getting into a vehicle driven by someone under the effects of these substances in order to identify risk factors and protective factors. Method: multicenter study cross sectional survey with students from a University in Colombia (n = 493) completed a survey prepared during the International Program of Training in Research for Health Professionals and Related Areas to Study the Drug Phenomenon in Latin America and the Caribbean. Results: an inverse relationship was observed between each of the three levels of risk perception: detection (p<.001), punishment (p<.05) and harm (p<.001), and driving behaviors with alcohol. This same type of relationship is observed with marijuana in terms of perceived risk of being involved in an accident (p<.05). However, regarding to marijuana, there is not enough evidence of an association with the perceived risk of being arrested or punished. The results show that there is an inverse relationship between what the students' relatives and friends think and do and the perception of risk of being arrested (p<.001), punished (p<.001) or of being involved in an accident (p<.001) for driving under the influence of alcohol and marijuana at the same time. Conclusion: the results suggest that there are risk factors and protective factors that can be intervened to prevent injuries or fatal events associated with driving under the influence of alcohol or marijuana
