The aim of this study was to investigate attitudes and awareness about conventional and electronic cigarettes in a sample of students attending the Faculty of Medicine of Pavia University (Italy). An anonymous and self-reported questionnaire was administered to 226 students attending either the first or third years of medical school during the 2013 to 2014 school year. Participation was voluntary and required signing an informed consent form. The prevalence of smokers was 12%. Sixty-seven percent of smokers reported smoking less than 5 cigarettes/day, and 15% more than 10 cigarettes/day...

The use of electronic cigarettes (e-cigarettes) is increasing, but their use as a smoking-cessation aid is controversial. The reporting of e-cigarette studies on cessation is variable and inconsistent. To date, only 1 randomized clinical trial has included an arm with other cessation methods (nicotine patches). The cessation rates for available clinical trials are difficult to compare given differing follow-up periods and broad ranges (4% at 12 months with non-nicotine e-cigarettes to 68% at 4 weeks with concomitant nicotine e-cigarettes and other cessation methods)...

The unregulated market for e-cigarettes continues to grow, with debates on their efficacy and impact on global public health. E-cigarettes, or electronic nicotine delivery systems (ENDs), are marketed as a 'safe' alternative to tobacco products and a tool for 'harm reduction'. Some public health experts are calling it a 'game changer' and favour the 'harm reduction' strategy, while others dispute this claim. In our opinion, the debate needs to be broadened to encompass other related concerns and effects on non-users and affected stakeholders...

BACKGROUND: Cigarette smoke has been identified as the main cause of oral cavity carcinoma. Recently, the electronic cigarette, a battery-operated device, was developed to help smokers stop their tobacco addiction. This study aimed to evaluate the safety of electronic cigarettes and to establish the possible role of such device in the primary prevention of oral cavity cancer. SUBJECTS AND METHODS: This study included 65 subjects who were divided into three groups (smokers, e-cigarette smokers, and nonsmokers)...

INTRODUCTION: Electronic cigarette (e-cigarette) use, or vaping, is increasing against a backdrop of declining smoking rates. E-cigarettes contain fewer toxicants than cigarettes, but their appearance and mode of use has the potential to satisfy the habitual aspects of smoking. To date, we know little about lay perceptions of the safety of using e-cigarettes in pregnancy. METHODS: We conducted a thematic discourse analysis of 13 online discussion forum threads that discussed e-cigarette use during pregnancy...

A randomised, parallel group clinical study was performed to evaluate the safety profile of an e-vapour product (EVP; 2.0% nicotine) in smokers of conventional cigarettes (CCs) switching to use the EVP for 12 weeks. During the study, no clinically significant product-related findings were observed in terms of vital signs, electrocardiogram, lung function tests and standard clinical laboratory parameters. Adverse events (AEs) reported by EVP subjects were more frequent during the first week after switching to the EVP...

BACKGROUND: Electronic cigarettes (e-cigarettes) are heavily marketed and widely perceived as helpful for quitting or reducing smoking intensity. We test whether ever-use of e-cigarettes among early adopters was associated with: 1) increased cigarette smoking cessation; and 2) reduced cigarette consumption. METHODS: A representative cohort of U.S. smokers (N = 2454) from the 2010 Tobacco Use Supplement to the Current Population Survey (TUS-CPS) was re-interviewed 1 year later...

BACKGROUND: Novel tobacco products entering the US market include electronic cigarettes (ECIGs) and products advertised to "heat, not burn" tobacco. There is a growing literature regarding the acute effects of ECIGs. Less is known about "heat, not burn" products. This study's purpose was to expand existing clinical laboratory methods to examine, in cigarette smokers, the acute effects of a "heat, not burn" "loose-leaf tobacco vaporizer" (LLTV). METHODS: Plasma nicotine and breath carbon monoxide (CO) concentration and tobacco abstinence symptom severity were measured before and after two 10-puff (30-s interpuff interval) product use bouts separated by 60min...

BACKGROUND: Information on e-cigarettes among youth in the Russian Federation is lacking. OBJECTIVE: We examined prevalence of and factors associated with youth e-cigarette use in the Russian Federation. METHODS: A cross-sectional, anonymous survey, conducted among 716 (females 51.5%) high school students in three cities (i.e., Ufa, Sterlitamak, Karagaevo) within the Republic of Bashkortostan, Russian Federation in 2015, assessed e-cigarette use and its correlates (i...

BACKGROUND: Young adults underutilize current evidence-based smoking cessation strategies; yet social media are widely used and accepted among this population. A better understanding of whether and how young adults try to quit smoking in the context of a social media smoking cessation intervention could inform future intervention improvements. OBJECTIVES: We examined frequency, strategies used, and predictors of self-initiated 24-hour quit attempts among young adults participating in a Facebook intervention...

Nicotine was not included in previous efforts to identify the most important toxicants of tobacco smoke. A health risk assessment of nicotine for smokers of cigarettes was conducted using the margin of exposure (MOE) approach and results were compared to literature MOEs of various other tobacco toxicants. The MOE is defined as ratio between toxicological threshold (benchmark dose) and estimated human intake. Dose-response modelling of human and animal data was used to derive the benchmark dose. The MOE was calculated using probabilistic Monte Carlo simulations for daily cigarette smokers...

The prevalence of e-cigarette use is increasing, yet few studies have focused on its use in racial/ethnic minority populations. We examined associations between race/ethnicity and e-cigarette use, plans to continue using e-cigarettes, and reasons for use among current/former smokers. Participants (285 in total; 29% non-Hispanic White, 42% African American/Black, and 29% Hispanic) were recruited between June and November 2014. Telephone-administered surveys assessed demographics, cigarette smoking, e-cigarette use, plans to continue using, and reasons for use...

We examine differences between college students and non-students with respect to orientation toward e-cigarettes. Participants were U.S. adults 18-24 (465 students, 409 non-students). Data collection employed an online survey by GfK Custom Research. Smoking, vaping, and use of alternate tobacco were assessed, as were variables from the Theory of Reasoned Action and Diffusion of Innovations. This study showed that smoking status largely explains use and orientation toward electronic cigarettes among both students and non-students, with differences attributable to higher smoking rates among non-students...

OBJECTIVES: Studies have identified a proliferation of e-cigarette advertisements on Twitter. We investigate whether the prevalence of e-cigarette related advertising is associated with state tobacco regulations after taking socio-economic characteristics into account. METHODS: We collected e-cigarette related tweets from July 23 to October 14, 2015 (n = 757,167) on Twitter. State regulations and smoking prevalence were provided by the Campaign for Tobacco-Free Kids program...

While the co-morbidity of alcohol (ethanol) and tobacco (nicotine) dependence is well described, the processes that underpin this strong connection are still under debate. With the increasing popularity of electronic cigarettes (e-cigarettes), it is now becoming more important to look to the neurobiological mechanisms involving alcohol and nicotine interactions to effectively treat a new generation of co-dependent individuals. Researchers have already recognized that the neuropathology produced by the combination of nicotine and ethanol is likely to produce an addictive nature very different to that of either one alone, and are employing a mixture of pre-clinical techniques to establish and investigate every stage in the development of both nicotine and ethanol-seeking behaviors...

BACKGROUND: Although smoking cessation is currently the only guaranteed way to reduce the harm caused by tobacco smoking, a reasonable secondary tobacco control approach may be to try and reduce the harm from continued tobacco use amongst smokers unable or unwilling to quit. Possible approaches to reduce the exposure to toxins from smoking include reducing the amount of tobacco used, and using less toxic products, such as pharmaceutical, nicotine and potential reduced-exposure tobacco products (PREPs), as an alternative to cigarettes...

OBJECTIVES: Electronic cigarettes (ECs) have recently become popular around the world, and their safety is being widely discussed in the scientific literature. Previous studies have examined the chemicals in e-liquids and vapour, and demonstrated that the aerosol from ECs can contain toxic chemicals that are harmful to health. However, little is known about the potential adverse health effects of passive exposure to EC vapour. The aim of this paper is to summarise and review all studies that have examined potential adverse health effects of passive exposure from inhaling EC vapour...

INTRODUCTION: Electronic cigarettes' (e-cigarettes) viability as a public health strategy to end smoking will likely be determined by their ability to mimic the pharmacokinetic profile of a cigarette while also exposing users to significantly lower levels of harmful/potentially harmful constituents (HPHCs). The present study examined the nicotine delivery profile of third- (G3) versus second-generation (G2) e-cigarette devices and their users' exposure to nicotine and select HPHCs compared with cigarette smokers...
