BACKGROUND: In cross-sectional surveys, increasing numbers of adolescents report using both electronic cigarettes (e-cigarettes) and cigarettes. This study assessed whether adolescent e-cigarette use was associated prospectively with initiation or escalation of cigarette use. METHODS: Data were from 2836 adolescents (aged 13-14 years at baseline) in 20 schools in England. At baseline, breath carbon monoxide levels, self-reported e-cigarette and cigarette use, sex, age, friends and family smoking, beliefs about cigarette use and percentage receiving free school meals (measure of socioeconomic status) were assessed...

Smoking is the leading cause of preventable death and chronic diseases in the U.S. Identifying smokers and providing appropriate intervention is therefore an integral part of each clinic visit. A combination of pharmacotherapy as well as behavioral counseling provides the best results. Pharmacotherapy includes nicotine replacement (patch, gum, lozenges), bupropion and varenicline. More recently, electronic nicotinic delivery systems (such as e-cigarettes, vaporizers/vape pens, and hookah pens) have become popular...

Regulations on e-cigarettes in the U.S. do not provide guidelines on the chemical content of e-cigarette liquids. We evaluated emissions of aldehydes and flavoring chemicals in e-cigarette vapor under typical usage conditions. We selected 24 e-cigarette flavors from the top selling disposable e-cigarette brands. E-cigarettes were connected to a pump drawing air for two second puffs with sixty-second intervals between puffs. The vapor was analyzed for the presence of aldehydes using high-performance liquid chromatography-ultraviolet detector and for the presence of flavoring chemicals with gas chromatography and an electron capture detector...

Background: Electronic cigarettes (e-cigarettes) are battery-powered devices that deliver aerosolized nicotine. With easy access and over-the-counter availability, many patients consider using electronic cigarettes for smoking cessation. Few studies have looked at long-term safety/efficacy and physician knowledge/attitudes toward e-cigarettes. Physicians have insufficient guidelines for advising their patients about e-cigarettes. Objective: 1) To identify knowledge and attitude of health care practitioners toward electronic cigarettes...

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...

Harm reduction debates are important in health policy. Although it has been established that morality affects policy, this article proposes that perspectives from moral psychology help to explain the challenges of developing evidence-based policy on prohibition-only versus tobacco/nicotine harm reduction for minors. Protecting youth from tobacco is critical, especially since tobacco/nicotine products are legal for adults, who usually begin using when young. Although cigarettes and other combustibles are the deadliest tobacco products, other products such as smokeless tobacco and electronic cigarettes, though unsafe, are upward of 90 percent less harmful than cigarettes...

Electronic cigarettes (e-cigs) have been gaining popularity and have emerged as a controversial tobacco product since their introduction in 2007 in the U.S. The smoke-free aspect of e-cigs renders them less harmful than conventional cigarettes and is one of the main reasons for their use by people who plan to quit smoking. The US food and drug administration (FDA) has introduced new regulations early May 2016 that went into effect on August 8, 2016. Given this important context, in this paper, we report results of a project to identify current themes in e-cig tweets in terms of semantic interpretations of topics generated with topic modeling...

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...

BACKGROUND: Prevalence rates of electronic nicotine delivery systems (ENDS; i.e., e-cigarette/vape) use has grown exponentially in the past few years. College students present a particularly vulnerable group for ENDS use. The current study sought to expand the literature by examining the context in which college students use ENDS, co-occurring health risks beyond traditional tobacco use, and the role of ethnicity in ENDS use. METHODS: Health-risk behavior survey data was collected from 452 undergraduates attending a large, public urban university during the 2015-2016 academic year...

E-cigarettes likely represent a lower risk to health than traditional combustion cigarettes, but they are not innocuous. Recently reported emission rates of potentially harmful compounds were used to assess intake and predict health impacts for vapers and bystanders exposed passively. Vapers' toxicant intake was calculated for scenarios in which different e-liquids were used with various vaporizers, battery power settings and vaping regimes. For a high rate of 250 puff day(-1) using a typical vaping regime and popular tank devices with battery voltages from 3...

Tobacco remains the leading preventable cause of death in the US, accounting for over 520,000 deaths annually. While the smoking prevalence has declined over the past 50 years, those with mental illness and addictive disorders continue to smoke at high levels and with significant tobacco-related health problems. Areas Covered: This review highlights the epidemiology, contributing factors, and evidence-base for intervening upon tobacco use in those with mental illness and addictive disorders. Historically underprioritized, a growing body of literature supports treating tobacco within mental health and addiction treatment settings...

Aerosol measurements were carried out in a model room where both combustion (conventional and hand-rolled cigarettes, a cigar and tobacco pipe) and non-combustion (e-cigarette and IQOS®) devices were smoked. The data were used to estimate the dose of particles deposited in the respiratory systems of individuals from 3months to 21years of age using the multiple-path particle dosimetry (MPPD) model. Regardless of the smoking device, the highest doses were received by infants, which reached 9.88×10(8)particles/kg bw during a cigar smoking session...
