Introduction: Craving may represent core motivational processes in tobacco dependence, but there is no psychometrically evaluated measure of craving for e-cigarettes (vaping craving). This research developed and validated a brief measure of vaping craving. Methods: The measure was evaluated in two studies. In Study 1, a 42-item questionnaire assessing a wide range of vaping craving content was administered to 209 current e-cigarette users. In Study 2, a 10-item questionnaire derived from Study 1 results was administered to 224 current e-cigarette users...

Background: LGBT populations use tobacco at disparately higher rates nationwide, compared to national averages. The tobacco industry has a history targeting LGBT with marketing efforts, likely contributing to this disparity. This study explores whether exposure to tobacco content on traditional and social media is associated with tobacco use among LGBT and non-LGBT. Methods: This study reports results from LGBT (N=1,092) and non-LGBT (N=16,430) respondents to a 2013 nationally representative cross-sectional online survey of US adults (N=17,522)...

BACKGROUND: We investigated tobacco-related self-identity and risk perceptions among adolescent tobacco users. METHODS: Data were analyzed for 20 675 US sixth- to 12th-graders from the 2016 National Youth Tobacco Survey. Students who reported past-30-day use of a specific tobacco product or ≥2 products but denied having used "any tobacco product" in the past 30 days were classified as not self-identifying as tobacco users. Tobacco product harm perceptions were further assessed across products...

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)...

BACKGROUND: Electronic cigarettes (e-cigarettes) may help cigarette smokers quit smoking, yet they may also facilitate cigarette smoking for never-smokers. We quantify the balance of health benefits and harms associated with e-cigarette use at the population level. METHODS AND FINDINGS: Monte Carlo stochastic simulation model. Model parameters were drawn from census counts, national health and tobacco use surveys, and published literature. We calculate the expected years of life gained or lost from the impact of e-cigarette use on smoking cessation among current smokers and transition to long-term cigarette smoking among never smokers for the 2014 US population cohort...

Many flavour compounds that are present in e-liquids for e-cigarettes are responsible for specific tastes and smoking sensations for users. Data concerning content and specific types of flavours is often limited and unknown to users. The aim of the research was to define and compare flavour profiles of e-liquids with the same group taste from different manufacturers. Gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) was used to separate and identify 90 popular compounds (98, including isomers) of interest...

BACKGROUND: Limited data exist on what young adults report as their first-ever nicotine product; some evidence suggests that they report hookah as their first product smoked. OBJECTIVES: This study reports on the first nicotine product used among undergraduates who had ever tried tobacco, and explores correlates of hookah as that first product. METHODS: Participants included a convenience sample of undergraduate students (n = 1538) at four universities in upstate New York during fall 2013...

This paper investigates the fate of the Capillary Aerosol Generator (CAG), a nicotine aerosol device resembling modern e-cigarettes, developed by Philip Morris (PM) in 1994. A debate has emerged as to why this product never made it to market. In Donovan et al. v. Philip Morris USA, Inc., the sides presented opposing views in their arguments. To explore the reasons for CAG abandonment, we searched the Truth Tobacco Industry Documents database for key terms including 'Capillary Aerosol,' 'Project LEAP' (the project under which the CAG was housed), and 'Tony Howell' (CAG inventor)...

BACKGROUND: The electronic cigarette (e-cigarette) industry has grown in size and organizational complexity in recent years, most notably with the entry of major tobacco companies in 2012 and the proliferation of vape shops. Many brands maintain retail websites that present e-cigarette marketing claims and sell directly to consumers. Understanding of the evolving composition of different types of e-cigarette brand websites is currently underdeveloped. OBJECTIVE: This paper presents how e-cigarette brand websites surveyed in 2013-2014 evolved by 2016-2017, and how the websites run by different types of e-cigarette producers currently differ...

BACKGROUND: With an increase in marijuana use among adults in the United States (US), understanding the potential impact of marijuana use on tobacco use and associated behavioral and health consequences, including respiratory conditions, is necessary. METHOD: Survey responses from Wave 1 of the nationally representative Population Assessment of Tobacco and Health (PATH) Study were used to assess tobacco use and marijuana use among non-current tobacco users (n = 17,952) and current established tobacco-users classified as: cigarette only users (n = 8689), e-cigarette only users (n = 437), cigar only (traditional, cigarillo, or filtered) users (n = 706), hookah only users (n = 461), smokeless tobacco only users (n = 971), cigarette + e-cigarette users (n = 709), and users of multiple tobacco products (n = 2314)...

Electronic (e)-cigarettes are devices intended to substitute conventional cigarettes, with the aim of being less harmful. In a previous report, we showed that i.p. injection of e-cigarette liquid (e-liquid), with or without nicotine, induced toxicity in the testes of Wistar rats by disrupting oxidative balance and steroidogenesis. In the present work, we further evaluated the impact of e-liquid with or without nicotine on the epididymis of rats using the same procedure. Results showed that e-liquid treatments led to alteration of semen parameters, with a significant drop of at least 50% in sperm vitality, a significant increase of morphologically abnormal spermatozoa and an imbalance of redox status in comparison to the control group...

OBJECTIVE: China produces the majority of the world's electronic cigarettes (e-cigarettes) and e-cigarettes have become popular in the country, especially among young people. However, little is known about the characteristics of e-cigarette use in China and how it is associated with smoking cessation behavior. This study focuses on the adolescent group in China and examines their perception and use of e-cigarettes and the association with smoking abstinence. METHODS: We use a mobile app-based survey on smoking behavior conducted in November 2015 in China, and focus on a sample of 2042 adolescents aged between 12 and 18...

Since their introduction to the United States in 2007, electronic cigarettes (e-cigarettes) use has grown exponentially. This rapid growth in e-cigarette use has been heralded by some as a potential important public health measure that could ultimately replace tobacco cigarettes, while others recommend a cautionary approach until there is clear evidence they will not become "new tobacco" bringing a possible myriad of other problems. E-cigarettes may have real benefits, however they do expose users and those nearby to organic compounds, solvents and particulate matter, with there being limited data relating to their health impact...

INTRODUCTION: Nicotine harms adolescent brain development and contributes to addiction. Some adolescents report using nicotine-free e-cigarettes, but the accuracy of their reporting is unclear. We explored adolescents' use of nicotine-free e-cigarettes and understanding of chemicals in e-cigarettes, including nicotine. METHODS: Using social media, we recruited 1589 US adolescents (aged 15-17) who reported past 30-day use of e-cigarettes in 2016. We assessed perceptions of the nicotine source in e-liquid and whether e-cigarette aerosol is just "water vapor...
