Introduction: The purpose was to measure nicotine levels to the tobacco and levels emitted to the aerosol of a heat-not-burn product (HnB, IQOS) compared to e-cigarettes (ECs) and a tobacco cigarette. Methods: The HnB device and regular and menthol sticks were purchased from Italy. Three types of ECs (ciga-like, eGo-style and variable wattage) and a commercially-available tobacco cigarette were also tested. A custom-made liquid containing 2% nicotine was used with ECs...

Introduction: This study examines patterns of change in different smoker subgroups' responses to new pictorial health warning labels (HWLs) over the initial, two year post-implementation period in Canada, where HWLs include package inserts with cessation messages, and Australia, where "plain" packaging (i.e., prohibition of brand imagery) was also implemented. Methods: Data were collected from online consumer panels in Canada (nsmokers=3,153; nobservations=5,826) and Australia (nsmokers=2,699; nobservations=5,818) from September 2012 to September 2014, with approximately 1,000 adult smokers surveyed in each country every four months, using replenishment to maintain sample size...

RATIONALE: Electronic cigarettes (ECs) are becoming popular alternatives for smokers, but there has been limited study of their abuse liability. OBJECTIVES: The objective of this study was to evaluate the abuse liability of three Vuse Solo ECs, ranging from 14 to 36 mg in nicotine content, relative to high- and low-abuse liability comparator products (usual brand combustible cigarettes and nicotine gum, respectively) in a group of 45 EC-naïve smokers. METHODS: Enrolled subjects' ratings of subjective effects and nicotine uptake over 6 h were used to measure abuse liability and pharmacokinetics following in-clinic use of each EC...

Tobacco use is the leading cause of death and disability in the United States; cigarette smoking is the most common form of tobacco use. Smoking has become increasingly concentrated among individuals with behavioral health needs (e.g., persistent mental illness) and has led to increased morbidity and mortality in this group relative to the general population. Comprehensive tobacco-free workplace programs are effective in reducing tobacco use and cigarette smoke exposure among behavioral health consumers and the individuals who serve them...

Neuroimaging of opiate-dependent individuals indicates both altered brain structure and function. Magnetic resonance-based arterial spin labeling has been used to measure noninvasively cerebral blood flow (i.e. perfusion) in alcohol, tobacco and stimulant dependence; only one arterial spin labeling paper in opiate-dependent individuals demonstrated frontal and parietal perfusion deficits. Additional research on regional brain perfusion in opiate dependence and its relationship to cognition and self-regulation (impulsivity, risk taking and decision making) may inform treatment approaches for opiate-dependent individuals...

BACKGROUND: Over the past decade, youth tobacco use has declined, and electronic cigarettes (e-cigarettes) have entered the market. The aims of this study were to describe the prevalence of e-cigarette use among youth in Canada, by province, across sociodemographic variables and smoking-related correlates; and to examine associations among e-cigarette use, sociodemographic variables and smoking-related correlates, with adjustment for other factors. METHODS: The 2014/15 Canadian Student Tobacco, Alcohol and Drugs Survey, a biennial, school-based survey, was administered to students in grades 6-12 in all Canadian provinces...

A consistent approach using standardised items to assess e-cigarette use in both youth and adult populations will aid cross-survey and cross-national comparisons of the effect of e-cigarette (and tobacco) policies and improve our understanding of the population health impact of e-cigarette use. Focusing on adult behaviour, we propose a set of e-cigarette use items, discuss their utility and potential adaptation, and highlight e-cigarette constructs that researchers should avoid without further item development...

BACKGROUND: Electronic cigarette (e-cigarette) use in the USA is increasing. As such, it is critical to understand who uses e-cigarettes, how e-cigarettes are used and what types of products are prevalent. This study assesses patterns of current e-cigarette use among daily and non-daily adult users in the 2013-2014 Population Assessment of Tobacco and Health (PATH) Study. METHODS: We examined the proportion of current adult e-cigarette users (n=3642) reporting infrequent use (use on 'some days' and use on 0-2 of the past 30 days), moderate use (use on 'some days' and use on >2 of the past 30 days) and daily use...

BACKGROUND: Magnetic resonance imaging studies of cigarette smoking-related effects on human brain structure have primarily employed voxel-based morphometry, and the most consistently reported finding was smaller volumes or lower density in anterior frontal regions and the insula. Much less is known about the effects of smoking on subcortical regions. We compared smokers and non-smokers on regional subcortical volumes, and predicted that smokers demonstrate greater age-related volume loss across subcortical regions than non-smokers...

Do graphic pictorial health warnings (GPHWs) on cigarette packaging work better for some people than others? According to the Extended Parallel Process Model (EPPM), fear appeals should heighten positive change only if a person believes he or she is capable of change (i.e., self-efficacy). We exposed 242 smokers and 241 nonsmokers (aged 18-29) in the Republic of Korea to either a GPHW or a text-only warning in a between-subjects experiment. Results indicated that the GPHW increased intentions and motivations to quit smoking (for smokers) and intentions and motivations to not start smoking (for nonsmokers)...

As there are many conflicting sources of e-cigarette information, research is needed to determine the impact of these sources on e-cigarette attitudes to inform future communication campaigns. Source credibility is important in shaping attitudes toward other health topics; however, no study has examined its role in influencing e-cigarette attitudes. Data from the 2015 Health Information National Trends Survey-FDA (HINTS-FDA) were utilized to assess differences in trust in different sources by e-cigarette user status and to investigate the associations between trust in sources and e-cigarette attitudes (n = 3,738)...

While interpersonal communication has been shown to influence smoking-related outcomes, mostly in the context of interventions, there is not much research showing what drives young people to talk about tobacco or e-cigarettes. Additionally, the changing media environment calls for research that expands the scope of what is included as interpersonal communication to include not just conversations but also online forms of communicating information. This study puts forth sharing as such a concept, and examines its prevalence and predictors in the context of tobacco and e-cigarette information...

Whilst e-cigarettes have been characterised by Public Health England as being around 95% less harmful than combustible tobacco products, only a minority of current smokers (around 16% within the UK) are using these devices. In this paper we report the results of an online survey of 650 smokers in contact with a smokers' rights group in the UK. A total of 91% of the smokers surveyed were smoking on a daily basis. Fifty nine percent reported having used electronic nicotine delivery systems, the majority of whom reported having used e-cigarettes...

AIMS: The aim of the study was to characterize e-cigarette users in terms of their consumption patterns, motives, and the perceived health benefits they experience from using e-cigarettes. DESIGN: The study was a cross-sectional online survey in 2015. A total of 3,320 German e-cigarette users were enrolled. A total of 91.5% were former tobacco smokers, 7.5% used both e-cigarettes and tobacco products, 1.0% were never-smokers. RESULTS: No differences were found between ex-smokers and dual users with regard to sociodemographic and smoking history (mean age 40...

Phospholipase A2 (PLA2)-dependent pathways are important in the regulation of cell proliferation, differentiation, motility, and immune responses, and can be dysregulated during tumor development and progression. We show herein, for the first time, that cigarette smoking leads to an increase in platelet-activating factor (PAF) content and PAF receptor expression in human breast cancer cells and tissue. PAF production could be abrogated in triple-negative breast cancer cells by inhibition of calcium-independent PLA2 (iPLA2)...

During 2011-2015, increased electronic cigarette (e-cigarette) and hookah use offset declines in cigarette and other tobacco product use among youths (persons aged <18 years) (1). Limited information exists about which tobacco product introduced youths to tobacco product use. Patterns of first use of e-cigarettes among Oregon youths who were tobacco users were assessed in the Oregon Healthy Teens 2015 survey, a cross-sectional survey of eighth and 11th grade students in Oregon. Respondents were asked, "The very first time you used any tobacco or vaping product, which type of product did you use?" Among students who had ever used any tobacco product (ever users), e-cigarettes were the most common introductory tobacco product reported by both eighth (43...

Tobacco use is the leading cause of preventable disease and death in the United States; nearly all tobacco use begins during youth and young adulthood (1,2). Among youths, use of tobacco products in any form is unsafe (1,3). CDC and the Food and Drug Administration (FDA) analyzed data from the 2011-2016 National Youth Tobacco Surveys (NYTS) to determine recent patterns of current (past 30-day) use of seven tobacco product types among U.S. middle (grades 6-8) and high (grades 9-12) school students. In 2016, 20...

BACKGROUND AND AIMS: Recreational marijuana legalization (RML) went into effect in Oregon in July 2015. RML is expected to influence marijuana use by adolescents and young adults in particular, and by those with a propensity for substance use. We sought to quantify changes in rates of marijuana use among college students in Oregon from pre- to post-RML relative to college students in other states across the same time period. DESIGN: Repeated cross-sectional survey data from the 2012-2016 administrations of the Healthy Minds Study...
