“…Three variables were found to be associated with use intentions via curiosity: positive expectancies about e‐cigarettes, having a larger number of family members who use e‐cigarettes, and having a larger number of friends who smoke conventional tobacco cigarettes. Of these, positive expectancies were found to be the most important, consistent with previous research on the factors associated with e‐cigarette use . Given previous research on the effects of e‐cigarette advertising among young adult non‐smokers has shown that positive portrayals of e‐cigarettes result in more favourable attitudes to the devices , maintaining existing regulations on the marketing of e‐cigarettes in Australia and other countries with similarly restrictive regulatory environments (e.g.…”

“…This research indicates that individuals who believe e‐cigarettes are less harmful than conventional cigarettes are more likely than those who do not hold this belief to use the devices . Some evidence is beginning to emerge on e‐cigarette expectancies, with research suggesting that beliefs about the positive experiences associated with e‐cigarette use (e.g., feeling relaxed) are linked with use of the devices . Although previous research suggests that sensation seeking traits are a major correlate of drug use and conventional cigarette smoking , just one study to date appears to have been conducted assessing the association between this individual personality trait and e‐cigarette use in young adults .…”

Introduction and Aims. A growing body of evidence suggests e-cigarette use increases the risk of conventional cigarette use. Assessing the factors associated with intentions to use e-cigarettes can inform programs designed to minimise uptake, potentially assisting in preventing a new population of smokers. This study developed and tested a model assessing the importance of various factors that may be associated with intentions to use e-cigarettes among young adults who have never used ecigarettes or tobacco cigarettes. Design and Methods. A web-panel provider recruited 429 Australian 18-to 25-year-olds who had never used e-cigarettes or smoked tobacco cigarettes (56% female, mean age = 21.17 years). Various individual and social factors were assessed as potential direct and indirect predictors of e-cigarette use intentions. Results. The developed model provided an excellent fit to the data and accounted for 49% of the variance in use intentions. Males had greater intentions to use e-cigarettes compared to females (β = −0.13). Having a greater number of friends who smoke tobacco cigarettes (β = 0.11) and curiosity about e-cigarette use (β = 0.58) were also directly associated with greater use intentions. Positive expectancies about e-cigarettes (β = 0.14), having family members who use e-cigarettes (β = 0.11), and having friends who smoke tobacco cigarettes (β = 0.07) were indirectly associated with intentions via curiosity. Discussion and Conclusions.Curiosity about e-cigarette use was strongly associated with use intentions. Aspects of the social environment were also important. Further research is needed to identify effective means of challenging positive e-cigarette expectancies given these were found to be strongly associated with intentions via curiosity.

“…Although the popularity of electronic smoking differs among European countries [7], it is common to hear about the growing popularity of vaping as such and of the emergence of a new concern for public healthcare and health (the effect on the organism of substances constituting e-liquid, including nicotine; the use of an e-cigarette as a source of cannabinoids and other prohibited drugs) [8][9][10]. Due to the short time of availability of electronic cigarettes, knowledge about their possible impact on human health is obscure [1].…”

Background. Of particular interest is a study of the consumption rates of some psychoactive drugs in a specific group of medical students and students-athletes, who are advocates of a healthy lifestyle according to their occupation. Objectives. The purpose of this paper was the evaluation of the prevalence of tobacco smoking and e-cigarette smoking (vaping) among medical students and students-athletes and the research of students' motivation and attitudes towards smoking in its various forms. Material and methods. 1,725 medical students and students-athletes were surveyed. All the respondents were divided into 4 groups: exclusive tobacco smokers, exclusive e-cigarette smokers, dual smokers (both e-cigarette and tobacco cigarette users), non-smoking students who hadn't smoked for at least 12 months. Results. 1,515 of the surveyed students (87.8%) declared themselves as non-smokers, 160 (9.3%) respondents smoked traditional cigarettes. E-cigarettes were used much less often than traditional cigarettes-50 respondents (2.8%). One-time tobacco smoking was recorded in the medical history of 992 (57.5%) of students; e-smoking-780 (45.2%). Statistically, men appeared to have been twice as common as women among both tobacco and e-cigarette smokers. Dual smokers used traditional cigarettes less often than electronic cigarettes. This group more often chose e-liquid with a higher level of nicotine. An attempt to stop smoking was the most important stimulus of opting for vaping (90.5%). Conclusions. Among the students of both groups, vaping is not frequent and not a popular practice compared to traditional tobacco smoking. Everyday smokers prevailed among dual smokers and not among exclusive e-cigarette smokers. E-smokers, more often than other respondents, believe that vaping is safe for their health and the health of others.

“…Most recently, studies have begun to extend this work to e-cigarettes. In a recent survey developed in part from qualitative interviews with young adult e-cigarette users, Pokhrel and colleagues (Pokhrel, Lam, Pagano, Kawamoto, & Herzog, 2018) demonstrated associations between young adults' positive and negative outcome expectations and e-cigarette willingness, use, and dependence. Positive youth outcome expectancies have also recently been linked with ecigarette initiation in a longitudinal study (Creamer et al, 2018).…”

Objectives: We conducted nationally representative surveys of adolescents and young adults to examine associations between e-cigarette outcome expectancies and e-cigarette use. Background: E-cigarette use among adolescents and young adults has grown rapidly in recent years, yet little research has examined the beliefs that may underlie this behavior among nationally representative samples. Methods: N= 1,298 adolescents (13-17) and 2,219 young adults (18-25) were surveyed using a probability-based web panel. Participants completed a survey that included a new outcome expectancy measure examining 3 positive (enjoyment, social influences, advantage over cigarettes) and 2 negative (health concerns, smoker association) expectancy domains and ever having used ecigarettes [ever use]. Results: Confirmatory factor analyses demonstrated a good fit of the outcome expectancies' factor structure to the data. All outcome expectancies were associated with e-cigarette use in both populations in univariate analyses. In multiple logistic regression models controlling for several covariates, higher expected enjoyment was positively associated with a greater likelihood of ecigarette use (aOR = 2.10, p < .05) among adolescents. Among young adults, enjoyment (aOR = 3.08, p < .001) was positively associated with a greater likelihood of use while both health concerns (aOR = 0.70, p < .01) and smoker association (aOR = 0.73, p < .05) were negatively associated with e-cigarette use. Conclusions: This study suggests that expected enjoyment is robustly associated with ecigarette use among both adolescents and young adults. Health concerns may also play a role in ecigarette use. Implications for e-cigarette prevention efforts and future research directions are discussed.
