这项横断面研究评估了马萨诸塞州、纽约州、罗德岛州和华盛顿州对调味电子烟销售的全州限制与2014年至2020年电子烟总销量之间的关系。从2014年到2020年，马萨诸塞州、纽约州、罗德岛州和华盛顿州对调味电子烟销售的全州限制是否与电子烟总销量的下降有关？在这项横断面研究中，对电子烟零售数据的差异分析表明，与没有限制的州相比，全州范围内对非烟草味电子烟销售的限制与电子烟总销量减少25.01%至31.26%有关。减少的主要原因是非烟草味电子烟销售的减少。在这项研究中，全州范围内对非烟草味电子烟的销售限制与电子烟销量的减少有关。电子烟是美国年轻人最常用的烟草产品。口味是年轻人使用电子烟最常见的原因之一，因此，一些州对调味电子烟的销售施加了限制。据我们所知，没有研究在控制了共同发生的事件的情况下，比较了有全州风味电子烟限制的州和没有这种限制的州之间的电子烟销售情况。评估在马萨诸塞州、纽约州、罗德岛州和华盛顿州实施的调味电子烟销售限制是否与2014年至2020年电子烟总销量的减少有关。这项采用差异中差异分析的横断面研究使用了马萨诸塞州、罗德岛州和华盛顿州的电子烟零售数据，这些州于2019年10月对调味电子烟的销售实施了限制；纽约于2020年5月实施了这些限制；35个州没有这些限制（控制州）。从2014年8月24日到2020年12月27日，销售汇总为4周，共2988个状态期观察。研究人员进行了一项差异中差异分析，将4个州（实施香味限制前后）的电子烟销量与35个对照州的电子烟销量进行了比较。该模型控制了其他基于人口的政策和突发事件（例如COVID-19大流行）。4周内的电子烟销量数据被分为4种口味（烟草、薄荷、薄荷和其他）。单位销售是标准化的，以反映最常见的包装尺寸为每个产品类型。与对照州相比，在2019年10月至2020年12月期间，全州范围内对非烟味电子烟销售的限制与干预州平均4周电子烟总销量的以下减少有关：纽约州减少30.65% (95% CI, 24.08%-36.66%)，罗德岛州减少31.26% (95% CI, 11.94%-46.34%)，华盛顿州减少25.01% （95% CI, 18.43%-31.05%）。在马萨诸塞州，与对照州相比，全面禁止所有电子烟产品的销售与四周销售额减少94.38% （95% CI, 93.37%-95.23%）相关。除了在马萨诸塞州，所有调味电子烟的销量都有所下降，在其他有限制的州，只有非烟草味电子烟的销量有所下降。在对照州，从2019年8月到2020年2月，平均销量下降了28.4%，但从2020年2月到12月，平均销量增长了49.9%。在这项横断面研究中，马萨诸塞州、纽约州、罗德岛州和华盛顿州对调味电子烟销售的全州限制与电子烟总销量的减少有关。这些发现表明，在政策实施后，并非所有购买非烟草味电子烟的电子烟用户都转而购买烟草味电子烟。
This cross-sectional study assesses the association of statewide restrictions on flavored e-cigarette sales in Massachusetts, New York, Rhode Island, and Washington with total e-cigarette unit sales from 2014 to 2020. Were statewide restrictions on flavored e-cigarette sales in Massachusetts, New York, Rhode Island, and Washington associated with a reduction in total e-cigarette unit sales from 2014 to 2020? In this cross-sectional study, a difference-in-differences analysis of e-cigarette retail data showed that statewide restrictions on non–tobacco-flavored e-cigarette sales were associated with reductions of 25.01% to 31.26% in total e-cigarette unit sales compared with total sales in states without restrictions. The reductions were attributable mostly to decreases in non–tobacco-flavored e-cigarette sales. In this study, statewide restrictions on sales of non–tobacco-flavored e-cigarettes were associated with reductions in e-cigarette sales. e-Cigarettes are the most commonly used tobacco product among US youths. Flavors are among the most cited reasons for use of e-cigarettes among youths, and therefore, some states have imposed restrictions on flavored e-cigarette sales. To our knowledge, no study has compared e-cigarette sales between states with statewide flavored e-cigarette restrictions and states without such restrictions while controlling for co-occurring events. To assess whether implementation of statewide restrictions on flavored e-cigarette sales in Massachusetts, New York, Rhode Island, and Washington was associated with a reduction in total e-cigarette unit sales from 2014 to 2020. This cross-sectional study with difference-in-differences analysis used e-cigarette retail sales data from Massachusetts, Rhode Island, and Washington, which implemented restrictions on flavored e-cigarette sales in October 2019; New York, which implemented these restrictions in May 2020; and 35 states without these restrictions (control states). Sales were summed into 4-week periods from August 24, 2014, to December 27, 2020, for a total of 2988 state-period observations. A difference-in-differences analysis was conducted to compare e-cigarette unit sales in the 4 states with flavor restrictions (before and after implementation) with those in the 35 control states. The model controlled for other population-based policies and emergent events (eg, the COVID-19 pandemic). Data on 4-week e-cigarette unit sales were sorted into 4 flavor categories (tobacco, menthol, mint, and other). Unit sales were standardized to reflect the most common package sizes for each product type. Statewide restrictions on non–tobacco-flavored e-cigarette sales were associated with the following reductions in mean 4-week total e-cigarette sales in intervention states compared with control states from October 2019 to December 2020: 30.65% (95% CI, 24.08%-36.66%) in New York, 31.26% (95% CI, 11.94%-46.34%) in Rhode Island, and 25.01% (95% CI, 18.43%-31.05%) in Washington. In Massachusetts, the comprehensive sales prohibition of all e-cigarette products was associated with a 94.38% (95% CI, 93.37%-95.23%) reduction in 4-week sales compared with control states. Except in Massachusetts, where all sales of flavored e-cigarettes decreased, reductions were found only for non–tobacco-flavored e-cigarette sales in the other states with restrictions. Among control states, mean sales decreased by 28.4% from August 2019 to February 2020 but then increased by 49.9% from February through December 2020. In this cross-sectional study, statewide restrictions on the sale of flavored e-cigarettes in Massachusetts, New York, Rhode Island, and Washington were associated with a reduction in total e-cigarette sales. These findings suggest that not all e-cigarette users who purchased non–tobacco-flavored e-cigarettes switched to purchasing tobacco-flavored e-cigarettes after policy implementation.
