ObjectivesAn increasing number of US states have required a tax on electronic nicotine delivery systems (ENDS) in the past few years. This study evaluated the effect of statewide vaping product excise tax policy on ENDS use among young adults.MethodsWe used the two recent waves (2014–2019) of the Tobacco Use Supplement to the Current Population Survey. A total of 17 896 US young adults were analysed. Difference-in-differences approach along with weighted multilevel logistic regressions were used to evaluate the association of vaping product excise tax policy adoption with current ENDS use, accounting for the clustering of respondents within the same states.ResultsThere was an increase in current ENDS use prevalence from 2014–2015 (3.4%) to 2018–2019 (5.4%). The presence of a tax on ENDS products was significantly associated with reduced current ENDS use (adjusted OR (AOR)=0.64, 95% CI=0.43 to 0.95). Importantly, respondents living in states with the policy showed significantly lower increase in ENDS use prevalence during the study period (interaction between within-state changes and between-state differences: AOR=0.57, 95% CI=0.35 to 0.91), controlling for other state-level policies and sociodemographic characteristics.ConclusionsOur findings suggest that adopting a vaping product excise tax policy may help reduce ENDS use and suppress the increase of ENDS use prevalence among young adults. Considering that there are still a number of US states that have not implemented vaping product excise tax policy, wider adoption of such policy across the nation would likely help mitigate ENDS use prevalence.

Исследованы особенности сбора аэрозоля электронных систем доставки никотина (ЭСДН) различных видов на лабораторной курительной машине линейного типа. Для исследований взяты ЭСДН трех торговых марок: одноразовые Luxlite неразборной конструкции закрытого типа; Von Erl My многоразового использования закрытого типа с жидкостью в сменных картриджах; Ego Aio многоразового использования открытого типа с резервуаром для самостоятельного заполнения. Проведен исчерпывающий сбор аэрозоля на лабораторной курительной машине линейного типа по ISO 20768:2018 в 2 режимах: стандартном ISO и экспериментальном ISOэксп c увеличенной продолжительностью затяжки. Установлено, что на один фильтр может быть собран аэрозоль для ЭСДН: Luxlite и Von Erl My от 50 затяжек, Ego Aio – 40 затяжек. Определен исчерпывающий сбор аэрозоля для ЭСДН, количество затяжек: Luxlite 250–300, Von Erl My 300–350, Ego Aio 160–200. Для ЭСДН Luxlite при режимах сбора аэрозоля по ISO и ISOэксп потери массы жидкости составили 2,7 и 4,8% соответственно. Потери массы жидкости ЭСДН Von Erl My/Ego Aio при режимах ISO и ISOэксп составили, %: 1-й цикл – 6,9/7,5 и 10,0/12,6; 2-й цикл – 7,9/30,7 и 8,1/49,2; 3-й цикл – 8,7/24,3 и 12,1/6,1; 4-й цикл – 11,6/44,5 и 10,1/22,7 соответственно. Отмечена стабильная работа устройств Luxlite и нестабильная Von Erl My и Ego Aio с протечками жидкости и потерями аэрозоля. Установлено, что увеличение продолжительности затяжки при режиме ISOэксп приводит к усилению продуцирования аэрозоля, снижению производительности ЭСДН и повышению потери массы жидкости для ЭСДН. Разработка метода сбора аэрозоля ЭСДН с учетом особенностей потребления и их конструкции позволит объективно оценить компонентный состав аэрозоля ЭСДН. The features of collecting aerosol of electronic nicotine delivery systems (ENDS) of various types on a laboratory machine smoking of linear type are investigated. For research, three brands of ENDS were taken: single-use Luxlite of non-collapsible closed-type design; Von Erl My refillable closed-type with liquid in replaceable cartridges; Ego Aio refillable open-type with a tank for self-filling. An exhaustive collection of aerosol was carried out on a laboratory Smoking machine of linear type according to ISO 20768:2018 in 2 modes: standard ISO and experimental ISOEXP with an extended duration of puffing. It was found that an aerosol can be collected per one filter for ENDS: Luxlite and Von Erl My from 50 puffs, Ego Aio – 40 puffs. An exhaustive collecting of aerosol for ENDS was determined, the number of puffs: Luxlite 250–300, Von Erl My 300–350, Ego Aio 160–200. For ENDS Luxlite under the collecting of aerosol according to ISO and ISOEXP, the loss mass of liquid was 2,7 and 4,8%, respectively. The mass loss of the Von Erl My/Ego Aio liquid in ISO and ISOEXP modes was, %: the 1st cycle – 6,9/7,5 and 10,0/12,6; the 2nd cycle – 7,9/30,7 and 8,1/49,2; the 3rd cycle – 8,7/24,3 and 12,1/6,1; the 4th cycle – 11,6/44,5 and 10,1/22,7, respectively. The stable operation of Luxlite devices and unstable operation of Von Erl My and Ego Aio devices with liquid leaks and aerosol losses were noted. It is established that the increase in the duration of puff under the regime ISOEXP leads to increased production of aerosol performance degradation ENDS and increase weight loss liquid for ENDS. The development of a method for collecting aerosol of ENDS, taking into account the characteristics of consumption and their design, will allow an objective assessment of the component composition of aerosol of ENDS.
