Kristy Marynak, Andrea Gentzke, Teresa W Wang, Linda Neff, Brian A King
Electronic cigarettes (e-cigarettes) are the most commonly used tobacco product among U.S. middle and high school students (1). Exposure to e-cigarette advertisements is associated with higher odds of current e-cigarette use among middle and high school students (2-4). To assess patterns of self-reported exposure to four e-cigarette advertising sources (retail stores, the Internet, television, and newspapers and magazines), CDC analyzed data from the 2014, 2015, and 2016 National Youth Tobacco Surveys (NYTSs)...

OBJECTIVE: To describe the prevalence and change in prevalence of electronic nicotine delivery systems (ENDS) use in youth by country and combustible smoking status. METHODS: Databases and the grey literature were systematically searched to December 2015. Studies describing the prevalence of ENDS use in the general population aged ≤20 years in a defined geographical region were included. Where multiple estimates were available within countries, prevalence estimates of ENDS use were pooled for each country separately...

The uneven diffusion of local and state laws restricting the use of electronic nicotine delivery systems (ENDS) in the United States may be a function of inconclusive scientific evidence and lack of guidance from the federal government. The objective of this study was to assess whether the rationale for amending clean indoor air acts (CIAAs) is being conflated by issues that are not directly relevant to protecting the health of ENDS non-users. Online sources were used in identifying bills ( n  = 25) that were presented in U...

BACKGROUND: Currently, an estimated 7.9 million US adults use electronic nicotine delivery systems (ENDS). Although published reports have identified fires and explosions related to use of ENDS since 2009, these reports do not provide national estimates of burn injuries associated with ENDS batteries in the US. FINDINGS: We analyzed nationally representative data provided in the National Electronic Injury Surveillance System (NEISS) to estimate the number of US emergency department (ED) visits for burn injuries associated with ENDS batteries...

Knowledge of the long-term toxicological and immunological effects of e-cigarette (e-cig) aerosols remains elusive due to the relatively short existence of vaping. Therefore, we performed a systematic search of articles published in public databases and analysed the research evidence in order to provide critical information regarding e-cig safety. Electronic nicotine delivery systems (or e-cigs) are an alternative to traditional cigarettes for the delivery of nicotine and are typically filled with glycerol or propylene glycol-based solutions known as e-liquids...

BACKGROUND: Electronic cigarettes (ECIGs) are devices with a heating element which produces aerosol for inhalation. They have been propagated as a healthier alternative to tobacco smoking and a potential device for smoking cessation, despite non-documentation of their long-term adverse health effects. OBJECTIVES: With the glorification of ECIG, its use has increased even among non-tobacco users. This makes it critical to understand and discuss a true picture about safety and utility of ECIGs by reviewing the literature...

Use of electronic nicotine delivery systems is flourishing among adolescents. The long-term effects have not been fully determined; however, literature suggests there is potential for significant harm. Providers must be aware of usage trends, device safety, and product knowledge. Adolescents should be evaluated through routine screening, and cessation counseling should be initiated.

INTRODUCTION: Electronic nicotine delivery systems (ENDS) arguably pose fewer health risks than smoking, yet many smokers adopt ENDS without fully relinquishing smoking. Known as 'dual use', this practice is widespread and compromises the health benefits that ENDS may offer. To date, few studies have explored how dual use practices arise and manifest. METHODS: We conducted in-depth, semi-structured interviews with 20 current ENDS users from New Zealand who reported smoking tobacco at least once a month...

Dosimetry models can be used to predict the dose of inhaled material, but they require several parameters including particle size distribution. The reported particle size distributions for aerosols from electronic nicotine delivery system (ENDS) products vary widely and don't always identify a specific product. A low-flow cascade impactor was used to determine the particle size distribution [mass median aerodynamic diameter (MMAD); geometric standard deviation (GSD)] from 20 different cartridge based ENDS products...

BACKGROUND: Smoking rates are disproportionately high among adults with mental health conditions (MHC), and recent research suggests that among former smokers, those with MHC are more likely to use electronic nicotine delivery systems (ENDS). This study investigated reasons for ENDS use and related risk perceptions among individuals with versus without MHC. METHODS: Among adult current ENDS users (n=550), associations between self-reported MHC diagnoses and motives for ENDS use and ENDS risk perceptions were examined, stratified by smoking status...

It is unclear whether use of electronic nicotine delivery systems (ENDS) precedes cigarette smoking initiation, relapse, and/or quitting. Healthcare systems with electronic health records (EHRs) provide unique data to examine ENDS use and changes in smoking. We examined the incidence of ENDS use (2012-2015) based on clinician documentation and tested whether EHR documented ENDS use is associated with twelve-month changes in patient smoking status using a matched retrospective cohort design. The sample was Kaiser Permanente Northern California (KPNC) patients aged ≥12 with documented ENDS use (N = 7926); 57% were current smokers, 35% former smokers, and 8% never-smokers...

The data presented here show that to provide an estimate of the relative cytotoxicity and therefore potency of e-cigarettes, undiluted aerosol techniques can be used. With the emergence of electronic nicotine delivery systems, fit-for-purpose in vitro screening methods are required. Reconstituted 3D human airway epithelium, was exposed to undiluted aerosols at the air-liquid interface, using a Vitrocell VC 10. TEER, cilia beat frequency and cytotoxic responses were assessed. Using two smoking regimes (ISO and HCI) a 3R4F reference cigarette, produced IC50s of 5...

Few published studies have investigated the presence of lead in the e-liquid of electronic nicotine delivery systems (ENDS). Lead inhalation is associated with increased risk of stroke, heart disease, and other diseases. This study used a novel application of graphite furnace technology to compare the concentration of lead between e-liquids of different packaging and product designs using e-liquids that are or were commercially available in the United States and Canada. Eleven nicotine-free disposable ENDS devices and 12 bottled refill solutions that contained nicotine were purchased from retailers in Canada and the United States between 2015 and 2017...

Public health agencies, the news media, and the tobacco/vapor industry have issued contradictory statements about the health effects of electronic nicotine delivery systems (ENDS). We investigated the levels of trust that consumers place in different information sources and how trust is associated with cultural worldviews, risk perceptions, ENDS use, and sociodemographic characteristics using a nationally representative sample of 6051 U.S. adults in 2015. Seventeen percent of adults were uncertain about their trust for one or more potential sources...

OBJECTIVE: American Indians (AI) have a high prevalence of electronic nicotine delivery system (ENDS) use. However, little information exists on (ENDS) use, either alone or in combination with cigarettes (dual use), among AI. The objective of this small-scaled study was to examine use behaviours and dependence among exclusive ENDS users and dual users of AI descent. Exclusive smokers were included for comparison purposes. SETTING: Oklahoma, USA. PARTICIPANTS: Adults of AI descent who reported being exclusive ENDS users (n=27), dual users (n=28) or exclusive cigarette smokers (n=27)...

The Food and Drug Administration, which now has regulatory authority over all tobacco products meeting the statutory definition, is tasked with communicating the risks of these products to the public through health warnings and public education. However, there have been no attempts to summarize what is known about non-cigarette tobacco product (NCTP) health messaging. We conducted a systematic review to examine the existing literature on health communication for NCTPs and identify key research gaps. A total of 45 unique studies were retrieved and coded, with the majority focused on messaging for smokeless tobacco (SLT, k = 32, 71...

BACKGROUND: Efforts to decrease adverse effects of tobacco use are affected by emergence of new nicotine delivery products. Advertising, product promotion, and social media promote use of these products, yet a lack of evidence regarding safety leaves nurses unprepared to counsel patients. OBJECTIVES: To critically evaluate current research, reviews of literature, expert opinion, and stakeholder policy proposals on use and safety of electronic nicotine delivery systems (ENDS)...
