This study explores the relationship between smoking habits, loneliness, and self-esteem among young adults. A sample comprising 144 non-smokers and 103 smokers was assessed using the Rosenberg Self-Esteem Scale, the UCLA Loneliness Scale, and the Fagerström Test for Nicotine Dependence (FTND). Statistical analysis revealed no significant differences in self-esteem and loneliness levels between smokers and non-smokers. These findings suggest that smoking status does not significantly impact loneliness or self-esteem in young adults, challenging common perceptions about the psychological correlates of smoking behavior. Further research is recommended to explore underlying factors and potential mediators in these relationships.
