                 Background: Gender differences in use of substances are decreasing. Aims and Objectives: Understanding underlie  reasons for smoking in the girls is the key for developing effective policy aimed at lowering the prevalence of smoking  among girls and young females. Materials and Methods: In this conventional content analysis study, 11 Iranian adolescent  girls aged 15–18 years old, was surveyed to explore their views about smoking. Through in-depth and semi-structured  interviews, participants were encouraged to talk about their smoking behavior freely. Results: The results of this study  revealed the following themes: Showing off, Conformance, Seeking to remove gender differences, and Confrontation.  Conclusion: Based on these findings, we discovered an adolescent girl’s smoking can somehow be a social activity mostly  performed as a means whereby her social needs are met. Indeed, there is a parallel relationship between adolescents’ need  for smoking and their psychosocial and developmental needs.
