“…To identify brands that young people in the US are using, we examined survey results from a cohort of participants recruited from a Midwestern state in the US, aged 15–24 years (55% female, 76% Non-Hispanic White) 21 , who reported their most commonly used e-cigarette brands at baseline (n=548) and at a 12-month follow-up (n=270). We also drew upon results from a national study of over 20 thousand US middle and high school students, where those reporting e-cigarette use were asked about their usual brands 22 .…”

INTRODUCTION E-cigarette use is most prevalent among adolescents and young adults – and there are often misperceptions about product risk. The purpose of this study was to determine what nicotine information is provided on e-cigarette brand websites. METHODS Based on national and local surveys, we identified 44 e-cigarette brands commonly used in the US by adolescents and young adults. For each of these brands, their associated websites were analyzed for disclosed nicotine information. Specifically, for each brand’s website, we coded whether there was information on nicotine concentration (recorded if a numerical value was provided such as ‘5% nicotine’), nicotine form (free-base, nicotine salts, or not stated), and nicotine type (tobacco-derived, synthetically derived, or not stated). Coding allowed for both lay (e.g. ‘nic salts’) as well as scientific (e.g. ‘isomers’) terms. RESULTS Of the 44 brands examined, all provided basic information on nicotine concentration (e.g. ‘5% nicotine’). However, 23% of brands did not disclose information on nicotine form (i.e. nicotine salt vs free-base), and 66% of brands did not disclose information on nicotine type (i.e. synthetic vs tobacco-derived). CONCLUSIONS Overall, these results suggest that the e-cigarette industry is not fully informing its consumers about the nicotine in their products. Given that nicotine form and type have implications for e-cigarette addiction potential, these findings highlight a public health concern. There is a need for more comprehensive national regulations for mandating product constituents and emissions disclosures.

AimsTo measure nicotine delivery, vaping topography and subjective effects of current generations of disposable, cartridge‐based and other types of electronic cigarettes (e‐cigarettes) among young adults.Design, setting, participantsObservational, human laboratory assessment of e‐cigarette use in Columbus, Ohio, USA (July 2020 to June 2021). Participants (n = 96, 60.4% female, age mean = 21.7 [standard deviation = 1.7] years, 82.4% white race) were identified via their participation in a cohort study or other convenience sampling and were 18 to 25 years old, vaped ≥4 days/week for ≥4 weeks and used other tobacco products for ≤5 days of past 30 days. Participants completed a pre‐vaping questionnaire, vaped their usual brand of e‐cigarette ad libitum for 30 min and completed a post‐vaping questionnaire.MeasurementsOutcome variables included pre‐ and post‐vaping measures of plasma nicotine (t = 0 and t = 30, respectively) and craving and withdrawal symptoms, as well as vaping topography (e.g. flow rate and inter‐puff interval), pre‐vaping expectancies and post‐vaping product appeal. Variables used to characterize the sample included demographics, e‐cigarette and other tobacco use history, e‐cigarette dependence and e‐cigarette device characteristics (e.g. device type, flavor and nicotine form).FindingsParticipants reported moderate nicotine dependence on average via the E‐Cigarette Dependence Scale (mean = 6.9 [standard deviation = 4.0]). Following 30 min of ad libitum vaping, participants achieved substantial plasma nicotine boost (mean = 18.8 [standard deviation = 14.5] ng/mL), corresponding with statistically significant decreases in withdrawal symptoms measured via the Minnesota Nicotine Withdrawal Scale (pre‐vaping mean = 9.0 [standard deviation = 5.1], post‐vaping mean = 4.3 [standard deviation = 3.9]; P‐value <0.0001). Pre‐vaping, participants reported moderate vaping expectancies (e.g. mean = 2.5 [standard deviation = 1.0] on a scale from 0 to 4 for smell and taste expectancies); post‐vaping, participants reported high satisfaction (mean = 4.6 [standard deviation = 1.2] on a scale from 1 to 7) and moderate reward (mean = 2.9 [standard deviation = 1.2]) and respiratory sensations (mean = 3.7 [standard deviation = 1.6]). Nearly half of participants (47.9%) used disposable e‐cigarettes, and most used a mint/menthol or fruit flavored (99.0%) and nicotine salt (98.9%) e‐liquid.ConclusionsAmong young adults in the United States, the latest generations of e‐cigarettes appear to deliver large quantities of nicotine (similar to cigarettes) and significantly relieve withdrawal symptoms, and they are appealing.
