To assess the impact of New York City's (NYC's) 2014 increase of the minimum legal purchase age (MLPA) for tobacco and e-cigarettes from 18 to 21 years.
We performed a difference-in-differences analysis comparing NYC to the rest of New York State by using repeated cross-sections of the New York Youth Tobacco Survey (2008-2016) and to 4 Florida cities by using the Youth Risk Behavior Surveys (2007-2015).
Adolescent tobacco use declined slightly in NYC after the policy change. However, this rate of change was even larger in control locations. In NYC, e-cigarette use increased and reported purchases of loose cigarettes remained unchanged, suggesting uneven policy implementation, enforcement, or compliance.
Increasing the MLPA to 21 years in NYC did not accelerate reductions in youth tobacco use any more rapidly than declines observed in comparison sites. Public Health Implications. Other cities and states currently raising their MLPA for tobacco may need to pay close attention to policy enforcement and conduct enhanced monitoring of retailer compliance to achieve the full benefits of the policy.
评估纽约市（NYC）2014 年将烟草和电子烟的最低合法购买年龄（MLPA）从 18 岁提高到 21 岁的影响。
我们通过使用纽约青年烟草调查（2008-2016 年）的重复横断面和佛罗里达州 4 个城市的青年风险行为调查（2007-2015 年），对纽约市与纽约州其他地区进行了差异分析。
政策变化后，NYC 青少年的烟草使用略有下降。然而，在对照组中，这一变化速度甚至更大。在 NYC，电子烟的使用有所增加，而散装香烟的购买量保持不变，这表明政策的执行、执法或遵守情况参差不齐。
将 MLPA 提高到 21 岁并没有比在对照地点观察到的下降更快地加速减少青少年的烟草使用。公共卫生意义。目前其他提高烟草 MLPA 的城市和州可能需要密切关注政策执行情况，并加强对零售商合规性的监测，以实现政策的全部效益。
