The use of electronic cigarettes or e-cigarettes is strongly on the rise. The literature confirms that in the process of quitting smoking using an electronic device dispensing nicotine should be a transitional stage before the complete cessation of smoking. The aim of the present study was to assess the popularity of e-cigarettes, the underlying reasons for use of such nicotine products, and the level of awareness of health hazards associated with e-cigarettes. The study is of a survey type. The material consisted of data collected from an anonymous survey distributed among 46 female and 23 male users of e-cigarettes in 2015...

Electronic cigarette use, or vaping, continues to be a focus for regulators and policy makers in public health, particularly since it can compete with or be a substitute for smoking. This study investigated characteristics of nicotine dependence and consumption in a sample of vapers who formerly smoked cigarettes. We recruited 436 (80% male) vapers from several internet discussion forums; 95% of whom previously smoked, but ceased after commencing vaping. These participants completed a retrospective version of the Fagerström Test for Nicotine Dependence (FTND-R), as well as a version modified to suit current vaping (FTND-V), along with measures of consumption...

Several US jurisdictions have recently passed laws that raise the minimum age of sale for tobacco products and electronic cigarettes to 21 years (Tobacco 21 laws). Although these laws have been demonstrated to be an effective means to reduce youth smoking initiation, their passage and potential expansion have provoked controversy. Critics have objected to these laws, claiming that they unduly intrude on individual freedom and that they irrationally and paternalistically restrict the freedom of those aged 18 to 20 years, who were previously able to legally purchase tobacco products...

PURPOSE: Some adolescent users of e-cigarettes and other electronic vaping products (EVPs) report performing "vape tricks" (exhaling aerosol to make shapes). However, little is known about this behavior. We examined the frequency of performing and watching vape tricks and the characteristics of those most likely to perform vape tricks among a sample of adolescent EVP users. METHODS: We used social media ads to recruit a national convenience sample of U.S. adolescents (n = 1,729) to participate in an online survey in September 2016...

BACKGROUND: Tobacco smoking is a leading cause of disease and premature mortality among Aboriginal and Torres Strait Islander (Indigenous) Australians. While the daily smoking prevalence among Indigenous Australians has declined significantly from 49% in 2001, it remains about three times higher than that of non-Indigenous Australians (39 and 14%, respectively, for age ≥15 years in 2014-15). This overview of systematic reviews aimed to synthesise evidence about reducing tobacco consumption among Indigenous peoples using a comprehensive framework for Indigenous tobacco control in Australia comprised of the National Tobacco Strategy (NTS) and National Aboriginal and Torres Strait Islander Health Plan (NATSIHP) principles and priorities...

Data on the effectiveness of strategies for the recruitment of American Indians (AIs) into research is needed. This study describes and compares methods for identifying and recruiting AI tobacco users into a pilot study. Community-based strategies were used to recruit smokers (n = 35), e-cigarette users (n = 28), and dual users (n = 32) of AI descent. Recruitment was considered proactive if study staff contacted the individual at a pow wow, health fair, or vape shop and participation on-site or reactive if the individual contacted the study staff and participation occurred later...

Electronic cigarette (e-cigarette) conventions are trade shows held across the globe to promote e-cigarette products and provide a venue for users to socialize. E-cigarette users that attend these events likely represent the most intensive e-cigarette user group. No study has characterized addiction and behavior characteristics in this population. We surveyed 131 e-cigarette users attending a large Southeastern e-cigarette convention in Fall 2015. All questions from the Fagerstrom Test for Nicotine Dependence (FTND), select questions from the Penn State Electronic Cigarette Dependence Index, and novel user behavior questions were included...

OBJECTIVES: Very few studies have evaluated perceptions of electronic nicotine delivery systems (ENDS) among smokers with mental illness. This study assessed expectancies about the effects of smoking combustible cigarettes or using ENDS among current smokers with and without severe psychological distress (SPD). METHODS: We used a crowdsourcing system to survey 268 smokers on their expectancies for the effects of combustible cigarettes and ENDS. Positive expectancies assessed included negative affect reduction, stimulation, positive social effects and weight control, and negative expectancies included negative physical effects, negative psychosocial effects and future health concerns...

Questions about electronic cigarettes, also called electronic nicotine delivery systems (ENDS), are very common when advising patients to stop smoking in medical practice. It is widely recognized that the risks of vaping are significantly lower than those of smoking, although there are uncertainties about its long-term health effects. Some studies suggest that vaping helps to stop smoking. Effective smoking cessation medications should be recommended in first line but vaping should not be discouraged when patients choose to use this device, as the main aim is smoking cessation...

INTRODUCTION: Cigarette smoking is one of the leading causes of early death in the UK and worldwide. Public health guidance recommends the use of varenicline, bupropion and nicotine replacement therapy (NRT) as smoking cessation aids in the UK. Additionally, the first electronic cigarette has been licensed for use as a smoking cessation medicine. However, there are ongoing concerns about the safety of these medicines. We present a protocol for a systematic review and network meta-analysis (NMA) to determine how these smoking cessation medicines compare to each other with respect to their neuropsychiatric safety in adult smokers...

Electronic cigarettes (E-cigarettes) are being widely used, and growing in popularity. It is estimated that more than 9 million adults use them regularly. The potential adverse health effects of electronic cigarette vapor (E-vapor) exposure are poorly defined. While several animal models of E-vapor exposure have been developed, few models expose rodents to clinically relevant quantities of nicotine and make direct comparisons to cigarette smoke within the same exposure system. Here, we present a method for constructing and operating an E-vapor chamber and cigarette smoke chamber...

Accurate and reliable measurements of exposure to tobacco products are essential for identifying and confirming patterns of tobacco product use and for assessing their potential biological effects in both human populations and experimental systems. Due to the introduction of new tobacco-derived products and the development of novel ways to modify and use conventional tobacco products, precise and specific assessments of exposure to tobacco are now more important than ever. Biomarkers that were developed and validated to measure exposure to cigarettes are being evaluated to assess their utility for measuring exposure to these new products...

Electronic cigarettes (e-cigs) are devices designed to deliver nicotine in a vaping solution rather than smoke and without tobacco combustion. Perceived as a safer alternative to conventional cigarettes, e-cigs are aggressively marketed as lifestyle-choice consumables, thanks to few restrictions and a lack of regulatory guidelines. E-cigs have also gained popularity among never-smokers and teenagers, becoming an emergent public health issue. Despite the burgeoning worldwide consumption of e-cigs, their safety remains largely unproven and it is unknown whether these devices cause in vivo toxicological effects that could contribute to cancer...

The use of electronic cigarettes (ECs) is rapidly increasing worldwide; however, scientific evidence regarding EC cytotoxicity is limited. The aim of this study was to evaluate the acute cytotoxicity of EC vapor extract (ECE) on airway-related cells in vitro. Cigarette smoke extract (CSE), vapor extract of fifteen brands/flavors of ECs and the extract from the E-vehicle (propylene glycol and glycerin) was collected. Extracts, in concentrations of 100-12.5%, were added to human bronchial epithelial (BEAS-2B, IB3-1 and C38), fibroblast (Wi-38) and macrophage (J774 and THP-1) cell lines...

BACKGROUND: The prevalence of tobacco smoking in Germany is high (~27%). Monitoring of national patterns of smoking behaviour and data on the "real-world" effectiveness of cessation methods are needed to inform policies and develop campaigns aimed at reducing tobacco-related harm. In England, the Smoking Toolkit Study (STS) has been tracking such indicators since 2006, resulting in the adaptation of tobacco control policies. However, findings cannot be directly transferred into the German health policy context...

Electronic cigarettes, or e-cigarettes as they are commonly called, have gained wide acceptance among adolescents, especially those with sweet flavors such as bubble gum and cheesecake. Although health effects of e-cigarettes have not been well characterized, their use increases a teen's exposure to nicotine and may serve as a gateway to traditional cigarettes. This article outlines the basics of e-cigarettes and potential health hazards, followed by selected literature on teens' perceptions of e-cigarettes, as well as motivational interviewing strategies that can be used in talking to teens about using electronic cigarettes...
