. The purpose was to determine the existence of factors of risk and protection associated with the consumption of alcohol, tobacco and marijuana in seventh through ninth grade students in educational centers in the city of San Salvador, El Salvador, Central America. Methodology. The study was focused on the prevention of alcohol, tobacco and marijuana consumption, because, according to the reviewed background, these are the most consumed drugs in the country. It was carried out in five study centers, with a descriptive approach and a transversal design, in a non-probabilistic sample of 268 students. Results. The consumption of alcohol, tobacco and marijuana among adolescents continues to be present with prevalence of consumption according to those reported by the country for this population in recent years, where the male sex had a higher consumption than female. We found 33 risk factors associated with the consumption of alcohol, tobacco and marijuana, and only 6 protection factors. Conclusion. It is considered that the existence of many risk factors and few protective factors in the environment are influencing a greater consumption of drugs and the low effectiveness of drug prevention programs or strategies in general.CREA CIENCIA Vol. 11 No 1-2 ISSN 1818-202X enero-diciembre 2017, p. 67-81
