Personal and interpersonal risk factors in the consumption of illicit drugs by marginal adolescents and young people from juvenile gangs.

Marginal populations are groups which are known to present higher risks of drug consumption. It is possible to identify adolescents and young people from juvenile gangs that constitute this group. The purpose of this study was to analyze the effect of personal and interpersonal risk factors of drug consumption in 175 marginal adolescents and young people who belong to juvenile gangs in Mexico. Results showed a significant effect of personal factors on drug use, with an estimated variation of 26.1%. The factors that presented the highest rates were: gender, age and mental problems. The interpersonal factors (relationships with friends who have maladaptive behaviors and inappropriate relationships with parents) showed an effect with an estimated variation of 15%. These results will allow for reflection and, in the future, the elaboration of adequate preventive programs aimed at this group of young people.
