Cherry-flavoured electronic cigarettes expose users to the inhalation irritant, benzaldehyde

Many non-cigarette tobacco products, including e-cigarettes, contain various flavourings, such as fruit flavours. Although many flavourings used in e-cigarettes are generally recognised as safe when used in food products, concerns have been raised about the potential inhalation toxicity of these chemicals. Benzaldehyde, which is a key ingredient in natural fruit flavours, has been shown to cause irritation of respiratory airways in animal and occupational exposure studies. Given the potential inhalation toxicity of this compound, we measured benzaldehyde in aerosol generated in a laboratory setting from flavoured e-cigarettes purchased online and detected benzaldehyde in 108 out of 145 products. The highest levels of benzaldehyde were detected in cherry-flavoured products. The benzaldehyde doses inhaled with 30 puffs from flavoured e-cigarettes were often higher than doses inhaled from a conventional cigarette. Levels in cherry-flavoured products were >1000 times lower than doses inhaled in the workplace. While e-cigarettes seem to be a promising harm reduction tool for smokers, findings indicate that using these products could result in repeated inhalation of benzaldehyde, with long-term users risking regular exposure to the substance. Given the uncertainty surrounding adverse health effects stemming from long-term inhalation of flavouring ingredients such as benzaldehyde, clinicians need to be aware of this emerging risk and ask their patients about use of flavoured e-cigarettes.

Exposure to Nicotine and Selected Toxicants in Cigarette Smokers Who Switched to Electronic Cigarettes: A Longitudinal Within-Subjects Observational Study

Introduction: Electronic cigarettes (e-cigarettes) are purported to deliver nicotine aerosol without any toxic combustion products present in tobacco smoke. In this longitudinal within-subjects observational study, we evaluated the effects of e-cigarettes on nicotine delivery and exposure to selected carcinogens and toxicants. Methods: We measured seven nicotine metabolites and 17 tobacco smoke exposure biomarkers in the urine samples of 20 smokers collected before and after switching to pen-style M201 e-cigarettes for 2 weeks. Biomarkers were metabolites of 13 major carcinogens and toxicants in cigarette smoke: one tobacco-specific nitrosamine (NNK), eight volatile organic compounds (1,3-butadiene, crotonaldehyde, acrolein, benzene, acrylamide, acrylonitrile, ethylene oxide, and propylene oxide), and four polycyclic aromatic hydrocarbons (naphthalene, fluorene, phenanthrene, and pyrene). Changes in urine biomarkers concentration were tested using repeated measures analysis of variance. Results: In total, 45% of participants reported complete abstinence from cigarette smoking at 2 weeks, while 55% reported continued smoking. Levels of total nicotine and some polycyclic aromatic hydrocarbon metabolites did not change after switching from tobacco to e-cigarettes. All other biomarkers significantly decreased after 1 week of using e-cigarettes (p < .05). After 1 week, the greatest percentage reductions in biomarkers levels were observed for metabolites of 1,3-butadiene, benzene, and acrylonitrile. Total NNAL, a metabolite of NNK, declined by 57% and 64% after 1 and 2 weeks, respectively, while 3-hydroxyfluorene levels declined by 46% at week 1, and 34% at week 2. Conclusions: After switching from tobacco to e-cigarettes, nicotine exposure remains unchanged, while exposure to selected carcinogens and toxicants is substantially reduced. Implications: To our knowledge, this is the first study that demonstrates that substituting tobacco cigarettes with an e-cigarette may reduce user exposure to numerous toxicants and carcinogens otherwise present in tobacco cigarettes. Data on reduced exposure to harmful constituents that are present in tobacco cigarettes and e-cigarettes can aid in evaluating e-cigarettes as a potential harm reduction device.

Taxing sugar-sweetened beverages: a survey of knowledge, attitudes and behaviours

OBJECTIVE To assess current beverage consumption patterns and anticipated reaction to an added 20 % tax on these products. DESIGN A random-digit dialled telephone interview lasting 20 min was administered to assess demographics, beverage consumption behaviours and intentions regarding consumption of sugar-sweetened beverages in the event of an additional tax on these beverages. SETTING Respondents were recruited throughout the USA. SUBJECTS The study included 592 adults. RESULTS Sixty-nine per cent of respondents reported consuming at least one pre-packaged sugar-sweetened beverage in the past week; those who consumed sugar-sweetened beverages averaged seven pre-packaged beverages per week. Ninety-one per cent knew that frequent consumption of soft drinks increases risk of obesity. Thirty-six per cent supported a tax on sugar-sweetened beverages with greatest support among those aged 18-24 years, those with BMI < 30 kg/m2 and those with higher levels of education (P < 0·05). Over one-third of respondents said that they would cut back on their sweetened beverage consumption in the event of an added 20 % tax on these beverages. CONCLUSIONS Our findings suggest that an added tax on these beverages could influence some to cut down on their consumption, reducing their risk of obesity and related illnesses.

Impact of smokeless tobacco packaging on perceptions and beliefs among youth, young adults, and adults in the U.S: findings from an internet-based cross-sectional survey

BackgroundResearch demonstrates that tobacco packaging elements (including health warning labels, descriptive characteristics, and corporate branding) are associated with knowledge of health risks and product appeal with cigarettes. Yet, little research has assessed this with smokeless tobacco (SLT) packaging. This study evaluates the association between three SLT packaging elements with knowledge of health risks and perceptions of novelty and appeal. Additionally, we assess how effects of these messages may differ across age groups, including youth (14-17 years), young adults (18-25 years), and older adults (26-65 years).Methods1000 participants were administered a web-based survey in 2010 and shown three sets of SLT packs in random order, varied by descriptor (flavor descriptor vs. none), warning label format (graphic vs. text), and corporate branding (branded vs. plain packaging). Participants rated the packs compared with “no difference” on appeal, novelty, and risk perceptions associated with product use. Chi-square tests were used to test for significant differences in pack selections. Multinomial regression was employed to evaluate the association between effects of packaging elements and participant age.ResultsMore respondents selected the pack with the graphic warning label as the pack to make them consider the health risks associated with SLT use, attract their attention, and be least attractive to a smoker. The product with the text warning label was the product someone their age would want to be seen using and would appeal to peers. The SLT pack with the flavor descriptor was not associated with health risks associated with product use. The pack with corporate branding was selected as more appealing, to attract attention, and one they would want to be seen using; the plain pack was less attractive to smokers. Youth and young adults were more likely to indicate that pack elements affected their perceptions of appeal and risk associated with SLT products.ConclusionThese results suggest that SLT pack characteristics have a measurable effect on perceptions of health risk and product appeal. Future research should assess these findings in the context of harm reduction. Specifically, research is needed to determine whether pack elements on SLT products can effectively convey risk and harm.

The Association of Exposure to Point-of-Sale Tobacco Marketing with Quit Attempt and Quit Success: Results from a Prospective Study of Smokers in the United States

The aim was to assess the association of exposure to point-of-sale (POS) tobacco marketing with quit attempt and quit success in a prospective study of smokers in the United States. Data were collected via telephone-interview on exposure to POS tobacco marketing, sociodemographic and smoking-related variables from 999 smokers in Omaha, Nebraska, in the United States. Exposure to POS tobacco marketing was measured by asking respondents three questions about noticing pack displays, advertisements, and promotions in their respective neighborhoods stores. These three variables were combined into a scale of exposure to POS tobacco marketing. About 68% of the respondents participated in a six-month follow-up phone interview and provided data on quit attempts and smoking cessation. At the six-month follow-up, 39.9% of respondents reported to have made a quit attempt, and 21.8% of those who made a quit attempt succeeded in quitting. Exposure to POS marketing at baseline was not associated with the probability of having made a quit attempt as reported at the six-month follow-up (p = 0.129). However, higher exposure to POS marketing was associated with a lower probability of quit success among smokers who reported to have attempted to quit smoking at six-month follow-up (p = 0.006). Exposure to POS tobacco marketing is associated with lower chances of successfully quitting smoking. Policies that reduce the amount of exposure to POS marketing might result in higher smoking cessation rates.

Associations between lifetime tobacco exposure with infertility and age at natural menopause: the Women's Health Initiative Observational Study

Background Several studies have investigated the association of tobacco use with infertility and age at natural menopause, yet few have explored secondhand smoke (SHS) exposure with these outcomes. This study offers a comprehensive, quantified secondary data analysis of these issues using the Womens Health Initiative Observational Study (WHI OS). Purpose This study examines associations between lifetime tobacco exposure—active smoking and SHS—and infertility and natural menopause (before age 50). Methods Information on smoking, lifetime fertility status, and age at natural menopause was collected and available from 93 676 postmenopausal women aged 50–79 enrolled in the WHI OS from 1993 to 1998 at 40 centres in the USA. Multivariate-adjusted regression models were used to estimate ORs and 95% CI according to levels of active smoking and SHS exposure, and trends were tested across categories. Results Overall, 15.4% of the 88 732 women included in the analysis on infertility met criteria for the condition. 45% of the 79 690 women included in the analysis on natural menopause (before age 50) met criteria for the condition. Active-ever smokers had overall ORs of 1.14 (95% CI 1.03 to 1.26) for infertility, and 1.26 (95% CI 1.16 to 1.35) for earlier menopause than never-smoking women. Never-smoking women with the highest levels of lifetime SHS exposure had adjusted ORs of 1.18 (95% CI 1.02 to 1.35) for infertility, and 1.18 (95% CI 1.06 to 1.31) for earlier menopause. Active-ever smokers reached menopause 21.7 months earlier than the mean of 49.4 years for never-smokers not exposed to SHS, and women exposed to the highest level of SHS reached menopause 13.0 months earlier. Conclusions Active smoking and SHS exposure are associated with increased risk of infertility and natural menopause occurring before the age of 50 years.

Tobacco sales in pharmacies: a survey of attitudes, knowledge and beliefs of pharmacists employed in student experiential and other worksites in Western New York

BackgroundPharmacies are venues in which patients seek out products and professional advice in order to improve overall health. However, many pharmacies in the United States continue to sell tobacco products, which are widely known to cause detrimental health effects. This conflict presents a challenge to pharmacists, who are becoming increasingly more involved in patient health promotion activities. This study sought to assess Western New York (WNY) area pharmacists’ opinions about the sale of tobacco products in pharmacies, and pharmacists’ opinions on their role in patient smoking cessation.MethodsParticipants responded to two parallel surveys; a web-based survey was completed by 148 university-affiliated pharmacist preceptors via a list based sample, and a mail-based survey was completed by the supervising pharmacist in 120 area pharmacies via a list-based sample. The combined response rate for both surveys was 31%. Univariate and bivariate analyses were performed to determine any significant differences between the preceptor and supervising pharmacist survey groups.ResultsOver 75% of respondents support legislation banning the sale of tobacco products in pharmacies. Over 86% of respondents would prefer to work in a pharmacy that does not sell tobacco products. Differences between preceptor and supervising pharmacist groups were observed. Action regarding counseling patients was uncommon among both groups.ConclusionsPharmacists support initiatives that increase their role in cessation counseling and initiatives that restrict the sale of tobacco products in pharmacies. These data could have important implications for communities and pharmacy practice.

Association between use of flavoured tobacco products and quit behaviours: findings from a cross-sectional survey of US adult tobacco users

Background Non-menthol characterising flavours (eg, fruit, candy) are banned in cigarettes, yet are still permitted in non-cigarette tobacco (NCT) products. This study examined associations between first use and current use of flavoured tobacco products, and current flavoured tobacco use and quit behaviours. Methods A nationally representative, telephone-based survey completed in 2012 by 1443 US adult tobacco users asked about use of 9 tobacco products: cigarettes, e-cigarettes, cigars, cigarillos, little filtered cigars, pipes, hookah, smokeless tobacco and snus. Ever users reported first use of flavoured products, while current users also reported current flavoured product use. Current users reported quit attempts made in the past year. Data were weighted to reflect the US adult tobacco user population. Logistic regression models were used to examine associations between first/current flavour use and quit behaviours. Results Over 70% of respondents reported first use of a flavoured tobacco product, while 54% reported current use of at least one flavoured product. Odds of current flavoured product use were greater among those who reported first use of a flavoured product (OR 14.82, 95% CI 9.96 to 22.06). First use of a flavoured product was associated with being a current tobacco user (OR 1.55, 95% CI 1.08 to 2.22). Compared to single product users, polytobacco users exhibited greater odds of reporting current use of flavoured products (OR 2.09, 95% CI 1.47 to 2.97). Forty-four percent of current tobacco users reported a past-year quit attempt. Adjusted analyses among current NCT users of at least one flavoured tobacco product showed reduced odds of reporting a quit attempt. Conclusions First use of a flavoured tobacco product was associated with current flavoured tobacco use and polytobacco use. Users of only flavoured NCT products exhibited reduced odds of reporting a quit attempt. Findings from this study reinforce the importance of flavoured product availability in the USA, which may have significant implications for efforts to reduce tobacco initiation and use at a population level. The relationship between characterising flavours and quit behaviours merits further exploration in longitudinal, population-based samples.

Factors Associated With Quitting Among Smoking Pregnant Women From Small Town and Rural Areas in Poland

Introduction Smoking rates among women in Poland are high, and access to specialized smoking cessation services in rural areas are limited. The aim of this study was to assess factors related to quitting among pregnant women who smoke in rural areas of Poland. Methods Data were collected during interviews conducted by midwives among 4512 women at various stages of their pregnancy. The interviews took place in small towns with populations having less than 8000 residents, located within 12 out of 16 voivodships (provinces). We used exhaled carbon monoxide to verify self-reported smoking status. Results Overall, 38% of women interviewed (n = 1578) smoked before they found out they were pregnant. Among these women, 33% quit just after they had become aware of their pregnancy. The main predictors of early quitting were: higher educational attainment among pregnant women (adjusted odds ratio [AOR] 3.21; 95% confidence interval [CI] = 1.81-5.68), secondary educational attainment among their partners (AOR 1.63; 95% CI = 1.06-2.48), and not having children (AOR 1.71; 95% CI = 1.31-2.24). The main barriers to early quitting were: living with at least one current smoker (AOR 0.55, 95% CI = 0.39-0.76), being single (AOR 0.45; 95% CI = 0.29-0.71), and having both parents smoke cigarettes (AOR 0.67; 95% CI = 0.46-0.97). Conclusions A modest proportion of women included in this study quit after they became aware of their pregnancy. However, women faced multiple barriers to quitting, including the smoking status of their family members. The factors identified in the study can inform the design of tailored interventions for pregnant women in rural areas. Implications Smoking rates among women in Poland are high, and access to specialized smoking cessation services in rural areas are limited. This study found that women were motivated to quit smoking, and many quit after they had become aware of their pregnancy. However, women faced multiple barriers to quitting, including the smoking status of their family members. The factors identified in the study can inform the design of tailored interventions for pregnant women in rural areas.

Youth Access to Electronic Cigarettes in an Unrestricted Market: a Cross-Sectional Study from Poland

Background: Electronic cigarette (e-cigarette) use among youths in Poland has become very popular. The aim of this study was to identify the potential points of access to these products by students aged 16–17 years old before implementation of sales restrictions to minors in Poland in November 2016. Methods: A school-based, cross-sectional survey was administered in 2015–2016 in 21 secondary/technical schools across two regions of Poland. Analyses focused on 341 students aged 16–17 years old who reported their past 30-day use of e-cigarettes. Pearson Chi-square analyses were utilized to examine the associations between access-related items, e-cigarette use and demographics. Results: Among youth e-cigarette users, the most common access to their first e-cigarette was from a friend (38%), followed by purchasing from vape shops (26%). Similar patterns emerged when the students were asked about their access to the currently used e-cigarette. Most youths reported no difficulty in purchasing cartridges/e-liquid containing nicotine (90%). The majority of users (52%) reported buying such products in vape shops. Conclusions: Prior to implementing age-related sales restrictions, youth access to e-cigarettes and paraphernalia did not pose any significant barriers. Poland’s introduction of a new age limit on e-cigarette sales may help to limit the number of youths who purchase e-cigarettes from vape shops.
