Brief summary: Substance use and drug related disorders are important public health problems. Alcohol and illicit drug use account for 5.4% of the total burden of disease and the peak has been found in early adulthood (between ages 20 and 30 years). Substance use is one of the leading problems among Chilean adolescents. One out of four 8 th to 12 th graders have smoked cigarettes in the last month. A 35.6% of students (37%, girls; 34.2%, boys) between Year 8 and Year 12 have reported any alcohol use during the last month. It is worrying that a third of 14 years old students report using alcohol in the last month in Chile. Furthermore, two out of three who are using alcohol, report regularly using 5 or more drinks in a row during the last month. Cannabis use among young Chileans has increased in recent years. Today, one out of five students between Year 8 and Year 12 referred cannabis use during the last 30 days. Almost a 20% of students in Year 8 have used cannabis in the last year.

Therefore, is urgent to provide evidence-based drug preventive interventions to the Chilean population, specifically to school students, to tackle this problem and reduce the risk for a more dramatic future health scenario.

The aim of this study was to assess the acceptability and feasibility of the cultural adaptation of "Yo Sé Lo Que Quiero" program. This is a pilot randomized controlled trial. The participants of this pilot were students attending six low-income primary schools in Santiago, Chile.

This pilot study is part of a larger research project with the final aim of testing the effectiveness of "Yo Sé Lo Que Quiero" program to reduce substance use among adolescents in Chile.

Eligibility criteria: Inclusion Criteria for schools:

* Mixed schools (boys and girls)
* Schools with a high vulnerability index, IVESINAE \> 70%. The IVESINAE is an indicator of the proportion of the students who have several risk factors regarding family income, parental education among other factors. This index is built by the Ministry of Education in Chile and help to direct resources to the schools.
* Located in the Metropolitan region in Chile.

Exclusion Criteria for schools:

* Having a structure and manualized substance use preventive program in place.
