Sense of need, decreasing stress, having a smoker friend, and inability to reject smoking suggestion were common reasons associated with tobacco smoking (P < 0.05). In addition, statistically significant differences between tobacco smokers and nonsmokers were found in the age, grade, mother&#39;s job, and education (P < 0.05). In comparison to non-smokers, tobacco smokers evaluated a typical smoker as less immature, more popular, more attractive, more self-confident, more independent, and less selfish person (P < 0.05).</p> </aside> <aside style="box-sizing: border-box; font-family: Lato, Arial; word-wrap: break-word; margin-bottom: 10px; font-size: 11px;"> <p style="box-sizing: border-box; word-wrap: break-word; margin: 0px 0px 10px; font-size: 12px; text-align: justify;"><span style="box-sizing: border-box; word-wrap: break-word; font-weight: 700;">Conclusions:</span>&nbsp;The results showed that the effect of several psychosocial, behavioral, and demographic risk factors on adolescents&#39; smoking status.
