Adolescents with conduct disorder: early smoking and treatment requests.

This study explored the relationship of a diagnosis of conduct disorder (CD) with the developmental smoking trajectory among 117 adolescent volunteers. Logistic regression analyses revealed that adolescents with CD smoked their first whole cigarette earlier (p = 0.03) and sought cessation treatment earlier (p = .01) compared to non-CD adolescents. Additionally, adolescents who smoked their first whole cigarette before the age of nine were eight times more likely to have CD. These findings suggest that in addition to addressing disruptive behaviors, early prevention and access to interventions for tobacco use are needed for youths with CD.
