This study evaluated the effects of tobacco Purchase, Use and Possession (PUP) laws on student perceptions of adolescent tobacco use within towns and schools. Twenty-four towns were randomly assigned into two conditions, the experimental condition (E PUP) involved efforts to increase both PUP law enforcement and reduce minors' access to commercial sources of tobacco, whereas the control condition (C) focused only on efforts to reduce minors' access to commercial sources of tobacco. A hierarchical linear modeling analytical approach was selected due to the multilevel data and nested design. The present study found that over time, youth in the experimental PUP condition observed less youth tobacco usage at school and in their town, and perceived lower rates of tobacco among their peers at school and among friends than youth in the control condition. The findings suggest that PUP law enforcement might be used to strengthen community norms against youth tobacco use.
本研究评估了烟草购买、使用和持有（PUP）法律对城镇和学校中学生对青少年烟草使用看法的影响。24 个城镇被随机分配到两种条件下，实验条件（E-PUP）涉及加强 PUP 执法和减少未成年人获得商业烟草来源的努力，而对照条件（C）则仅关注减少未成年人获得商业烟草来源的努力。由于多水平数据和嵌套设计，选择了分层线性建模分析方法。本研究发现，随着时间的推移，实验 PUP 条件下的青少年在学校和城镇观察到的青少年吸烟行为较少，与对照条件下的青少年相比，他们在学校和朋友中观察到的烟草使用率较低。研究结果表明，PUP 执法可能被用于加强反对青少年吸烟的社区规范。
