Objective: to analyze the perceptions and experiences of the phenomena of violence and the use of alcohol and other drugs by adolescents in a context of social vulnerability. Method: this is a qualitative, exploratory study, according to the principles of strategic social research, carried out in 2019 with 12 adolescents between 15 and 18 years of age, through a semi-structured audio-recorded interview. The results were transcribed and analyzed in the thematic modality of content analysis. Results: Three thematic categories emerged from the interviews: "The experience of violence in the community context", "Social and community life impaired by drugs and violence", and "Factors related to overcoming social vulnerability" and, in short, demonstrated that adolescents live in an unequal and vulnerable environment, with limited development opportunities, marked by a poor social network and interaction. Final considerations: although the adolescents participating in the research presented knowledge restricted to violence and the phenomenon of drugs, we observed that they recognize the importance of behavioral aspects inherent to social skills for healthy and successful community living.
