Abstract

Background and aims: As of 2023, Elfbar remains the most popular brand of disposable e-cigarette available in the United States (US) and United Kingdom (UK), with similar flavor options in both countries. At the time of this study, 5% nicotine Elfbar BC5000 was the only version available in the US, whereas 2% Elfbar 600 was the most popular in the UK. This study measured differences in nicotine content and form, aerosol emissions and flavoring chemicals in the US and UK Elfbar products.

Method: A convenience sample of eight Elfbar devices sold in the US and UK, consisting of two Elfbar models with four identical flavor options (Peach Ice, Strawberry Banana, Strawberry Ice and Strawberry Kiwi) purchased between December 2022 and February 2023, were laboratory tested. We measured nicotine concentration, form and total content. We also determined aerosol emissions and estimated the nicotine dose delivery per puff. We identified solvents and flavoring chemicals in these products.

Results: Elfbar products within the same country had similar nicotine content, concentration, form and solvents, but they differed in flavoring chemicals. US Elfbar contained, on average, higher volume (mean ± standard deviation = 6.5 ± 0.5 versus 1.8 ± 0.3 ml) of nicotine solution with a higher concentration (41.8 ± 2.3 versus 19.7 ± 1.2 mg/ml) than the UK Elfbar. An estimated dose of nicotine delivered per puff was four times higher from US Elfbar than UK Elfbar. There were differences in the type and amount of flavoring chemicals used in US and UK Elfbars, including a higher concentration of a synthetic coolant WS-23 in US Elfbar than in UK Elfbar (17.8 ± 1.5 versus 12.9 ± 5.4 mg/ml).

Conclusions: Because the amount of nicotine found in the US Elfbar e-cigarettes is equivalent to that found in eight UK Elfbar e-cigarettes, people who use Elfbar sold in the US have access to much more nicotine from a single device than those who use Elfbar sold in the United Kingdom.

在美国和英国销售的一次性 "Elfbar "电子烟的特征和成分。

背景和目的：截至2023年，Elfbar仍是美国和英国最受欢迎的一次性电子烟品牌，两国的口味选择相似。在本研究进行时，尼古丁含量为 5% 的 Elfbar BC5000 是美国市场上唯一的版本，而尼古丁含量为 2% 的 Elfbar 600 在英国最受欢迎。这项研究测量了美国和英国Elfbar产品在尼古丁含量和形式、气溶胶排放和调味化学品方面的差异：实验室测试了在美国和英国销售的八款Elfbar设备，包括两款Elfbar型号和四种相同口味（桃子冰、草莓香蕉、草莓冰和草莓猕猴桃），购买时间在2022年12月至2023年2月之间。我们测量了尼古丁的浓度、形态和总含量。我们还测定了气溶胶排放量，并估算了每吸一口的尼古丁剂量。我们确定了这些产品中的溶剂和调味化学品：结果：同一国家的 Elfbar 产品在尼古丁含量、浓度、形态和溶剂方面相似，但在调味化学品方面存在差异。与英国 Elfbar 相比，美国 Elfbar 的尼古丁溶液平均含量更高（平均值 ± 标准偏差 = 6.5 ± 0.5 对 1.8 ± 0.3 毫升），浓度更高（41.8 ± 2.3 对 19.7 ± 1.2 毫克/毫升）。每吸一口的尼古丁估计剂量是美国 Elfbar 的四倍。美国和英国艾尔菲巴所使用的调味化学品的类型和数量存在差异，其中美国艾尔菲巴中合成冷却剂WS-23的浓度高于英国艾尔菲巴（17.8 ± 1.5对12.9 ± 5.4毫克/毫升）：结论：由于美国 Elfbar 电子烟中的尼古丁含量与 8 支英国 Elfbar 电子烟中的尼古丁含量相当，因此使用美国销售的 Elfbar 电子烟的人可以从单一设备中获得比使用英国销售的 Elfbar 电子烟的人多得多的尼古丁。

期刊介绍： Addiction publishes peer-reviewed research reports on pharmacological and behavioural addictions, bringing together research conducted within many different disciplines. Its goal is to serve international and interdisciplinary scientific and clinical communication, to strengthen links between science and policy, and to stimulate and enhance the quality of debate. We seek submissions that are not only technically competent but are also original and contain information or ideas of fresh interest to our international readership. We seek to serve low- and middle-income (LAMI) countries as well as more economically developed countries. Addiction’s scope spans human experimental, epidemiological, social science, historical, clinical and policy research relating to addiction, primarily but not exclusively in the areas of psychoactive substance use and/or gambling. In addition to original research, the journal features editorials, commentaries, reviews, letters, and book reviews.
