This study describes student perceptions of school staff smoking before and after implementation of legislation prohibiting smoking on school grounds. Students completed self-report questionnaires before (grade 6) and after (grade 7, 9 and 11) the law. The percentage of students reporting that school staff smoked in areas where smoking is forbidden was 19%, 32% and 33% in grade 7, 9 and 11, respectively. The mean(SD) score for the frequency with which students saw school staff smoking decreased after the ban but increased thereafter [2.5(1.1), 1.9(1.0), 2.4(1.1) and 2.3(1.1)] in grade 6, 7, 9 and 11, respectively [F(2.861,1662.229) = 45.350, P &lt; 0.001]. These data suggest that the effect of the law dissipated over time.

Effect of anti-smoking legislation on school staff smoking may dissipate over time
