E-cigarette devices used by high-school youth

Abstract

Background: E-cigarette use rates are high among youth, but there is limited information on the types of e-cigarette devices that are used by youth. Methods: During Spring 2017, students from 4 high schools completed surveys on use of e-cigarette devices (cig-a-like, vape/hookah pen, modified devices or mods, and JUUL). Among youth who endorsed ever (lifetime) use of an e-cigarette and of at least one device (n=875), we assessed 1) prevalence rates of ever and current (past-month) use of each device, 2) use of nicotine in each device, and 3) predictors [age, sex, race, socioeconomic status (SES), other tobacco use] of ever use of each device and of use of single versus multiple devices. Results: Cig-a-likes were used least frequently (Ever use: cig-a-likes: 25.4%; vape/hookah pens: 60.6%; JUUL: 64.2%; mods: 71.2%; Current use: cig-a-likes: 7.3%; vape/hookah pens; 18.7%; mods: 33.1%; JUUL: 47.1%;). Nicotine use was highest for JUUL (JUUL: 80.3%; mods: 56.3%; cig-a-likes: 51.4%; vape/hookah pens: 46.8%). Among ever users of single devices, use of JUUL was highest (JUUL: 43%; mods: 32%; vape/hookah pens: 21%; cig-a-likes: 4%). Ever use of all devices, except JUUL, was associated with other tobacco product use. Ever use of JUUL was associated with higher SES. Ever use of multiple devices (two: 34.7%; three: 25.8%; four: 11.7%) compared with a single device (27.8%) was associated with other tobacco product use. Conclusions: Targeted regulatory and prevention efforts that consider the use of multiple e-cigarette devices are needed to lower youth e-cigarette use rates.

Flavored E-cigarette Use and Progression of Vaping in Adolescents

“…On the basis of the literature, [20][21][22][23][24][25][26][27][28] we identified a priori covariates considered to be conceptually peripheral to the putative risk pathway, which could increase exposure to flavored e-cigarettes as well as alter vaping patterns and could therefore confound associations.…”

“…Forced choice of 1 of 8 race and/or ethnicity categories (American Indian and/or Alaskan native, Asian American, Black and/or African American, Hispanic and/or Latino, Native Hawaiian and/or Pacific Islander, white, multiethnic and/or multiracial, or other) was recoded into a 4-level variable (Hispanic, white, Asian American, and other race and/or ethnicity). 21,22 Because chronicity of vaping and device type may be associated with vaping patterns and e-cigarette flavors used, 26,27 additional covariates included age of vaping onset 25 (years; continuous variable) and e-cigarette device type 26,27 (forced choice: cigalike [appearance similar to combustible cigarette, nonrefillable, low power], midsize tank [appearance similar to a large pen, refillable, rechargeable, moderate to high power], or advanced personal vaporizer or modified electronic cigarette or "Mod" [similar in size to a smartphone, high power, modifiable, refillable]; assessed only at wave 2). Sensation seeking, assessed with the 12-item subscale of the urgency, perseverance, premeditation, and sensation seeking (UPPS) Impulsive Behavior Scale 28 (eg, "I generally seek new and exciting experiences and sensations"; Cronbach's a = 0.93) 29 at wave 1, was included because it could influence the pursuit of flavors and vaping pattern.…”

Trendy e-cigarettes enter Europe: chemical characterization of JUUL pods and its aerosols

“…E-liquids of the brand JUUL contain benzoic acid and high nicotine concentrations of up to 5%. The brand had reached a market share of about 40% in the US by the end of 2017 (Huang et al 2019) with high popularity among adolescents (Hammond et al 2019;Krishnan-Sarin et al 2019). This is likely due to viral marketing and the spreading of the product via social media and YouTube (Allem et al 2018;Brett et al 2019;Chu et al 2018;Czaplicki et al 2019;Kavuluru et al 2019;Ramamurthi et al 2019).…”

Usage of Electronic Cigarette and its Effects on Health
