This study examined adolescent attitudes towards tobacco control laws. An exploratory factor analysis, using surveys from over 9,000 students, identified the following three factors: (1) youth attitudes towards the efficacy of tobacco control laws, (2) youth attitudes towards tobacco possession laws and (3) youth attitudes towards tobacco sales laws. Findings revealed that smokers reported less favorable attitudes towards the efficacy of tobacco control laws, tobacco possession laws, and tobacco sales laws than non-smokers. In addition, youth in lower grade levels reported more support for the efficacy of tobacco control laws and tobacco possession laws than those in higher grades. Findings indicate that there are different dimensions of youth attitudes towards tobacco control laws, and that smoking status and grade in school have important relationships to these different factors. This understanding might better allow the perspectives of youth to be an additional consideration when developing and implementing laws aimed at minimizing underage smoking.
