Introduction: the usage of Information and Communication Technology (ICT) to treat psychological problems such as addictions, is a recent issue that has allowed the recognition that the use of this type of tools is effective towards the problem they claim to solve, in a similar way as traditional therapy treatments do. Objective: to evaluate the efficacy of the Brief Intervention Program for Adolescents who Abuse Drugs (PIBA) and the Brief Advice in the Web Page modality regarding the barriers in the implementation of drug abuse treatments by the COVID-19 pandemic. Method: we started from a A-B-A single-case design with high school adolescent students who reported abusive use and associated consequences. The study consisted of four stages 1) evaluation, 2) admission, 3) PIBA or Brief Advice and 4) follow-up. Results: the results obtained showed a decrease in the pattern of alcohol consumption and an increase in self-efficacy to control consumption in various risk situations. Discussion and conclusions: the program provided the necessary tools for adolescents to maintain their consumption goal.
