This case study examines the comparative effect of no-use school tobacco policies and restricted-use tobacco policies on teacher and student smoking behaviors and attitudes. Data from teachers (n = 1,041) and ninth-grade students (n = 4,763) at 20 schools in five districts in southern Louisiana were available. No significant difference was observed between teacher smoking (11% vs. 13%, p = .42) or student smoking (24.6% vs. 25.2%, p = .75) at no-use versus restricted-use policy schools. The proportion of teachers smoking on campus at no-use or restricted-use schools was not significantly different. Teachers at restricted-use schools were however less concerned about students seeing teachers smoke and less supportive of a no-use policy than teachers at no-use schools. Tobacco use policies are often not promoted, and enforcement of policies impacting teachers is complex. Changing social norms for smoking at high schools through policy promotion and enforcement is understudied.
