    ABSTRACT: Adolescents' use of electronic cigarettes (e-cigarettes) and exposure to e-cigarette TV advertising have increased in recent years, despite questions about their safety. The current study tests whether exposure to e-cigarette TV advertisements influences intentions to use e-cigarettes in the future and related attitudes. A parallel-group randomized controlled experiment was conducted and analyzed in 2014 using an online survey with a convenience sample of 3,655 U.S. adolescents aged 13-17 years who had never tried e-cigarettes. Adolescents in the treatment group viewed four e-cigarette TV advertisements. Adolescents in the treatment group reported a greater likelihood of future e-cigarette use compared with the control group. ORs for the treatment group were 1.54 (p=0.001) for trying an e-cigarette soon; 1.43 (p=0.003) for trying an e-cigarette within the next year; and 1.29 (p=0.02) for trying an e-cigarette if a best friend offered one. Adolescents in the treatment group had higher odds of agreeing that e-cigarettes can be used in places where cigarettes are not allowed (OR=1.71, p<0.001); can be used without affecting those around you (OR=1.83, p<0.001); are a safer alternative to cigarettes (OR=1.19, p=0.01); and are less toxic (OR=1.16, p=0.03). Exposure to e-cigarette advertising had relatively large and consistent effects across experimental outcomes. Together with the simultaneous increase in e-cigarette advertising exposure and e-cigarette use among adolescents, findings suggest that e-cigarette advertising is persuading adolescents to try this novel product. This raises concerns that continued unregulated e-cigarette advertising will contribute to potential individual- and population-level harm. Copyright © 2015 American Journal of Preventive Medicine.

    ABSTRACT: Recent youth trends in the prevalence of e-cigarette and traditional cigarette use in Florida were examined in a cross-sectional, representative state sample from 2011 to 2014. Traditional cigarette use among youth declined during the study period. Experimentation with and past 30-day use of e-cigarettes among Florida youth tripled over 4 years. Past 30-day e-cigarette use exceeded traditional cigarette use in 2014; 10.8% of high school and 4.0% of middle school students reported recent e-cigarette use, compared with 8.7% of high school and 2.9% of middle school students for traditional cigarettes (P<0.001). By 2014, 20.5% of high school and 8.5% of middle school students reported ever use of e-cigarettes. Among ever e-cigarette users in 2014, 30.3% of high school and 42.2% of middle school students had never smoked traditional cigarettes. Given the concern that significant rates of e-cigarette use by U.S. adolescents may have a negative effect on public health, further review of e-cigarette advertising, marketing, sales, and use among U.S. youth is warranted.

    ABSTRACT: This study explores whether exposure to advertisements that focus on the negative effects of tobacco industry advertising and promotion at the point of sale (anti-POS advertising) influence: (i) attitude toward POS advertising; (ii) perceived impact of POS advertising on youth smoking; and (iii) support for a ban on tobacco promotion at the POS among adult non-smokers in New York. Data are from a split-sample, experimental study, using an online media tracking survey with embedded TV, radio and print advertising. Exposure to anti-POS advertising was associated with higher odds of holding a negative attitude toward POS advertising (OR 2.43, P < 0.001) and support for a ban on tobacco promotion at the POS (OR 1.77, P < 0.05), but not with perceived impact of POS tobacco advertisements on youth smoking. Findings suggest the possibility that a mass media campaign could be used to influence public attitude toward POS advertising and support for a ban on tobacco promotion at the POS. © The Author 2014.

    ABSTRACT: Abstract Objective . This review synthesizes the published literature on using mass media campaigns to reduce youth tobacco use, with particular focus on effects within population subgroups and the relative effectiveness of campaign characteristics. Data Source . A search of PubMed and PsycINFO conducted in March of 2014 yielded 397 studies with 34 suitable for inclusion. Study Inclusion and Exclusion Criteria . Included were quantitative studies that evaluate an antitobacco media campaign intended to influence youth cognitions or behavior or explore the relative effectiveness of campaign characteristics among youth. Data Extraction . An automated search and assessment of suitability for inclusion was done. Data Synthesis . Study outcomes were compared and synthesized. Results . Antitobacco media campaigns can be effective across racial/ethnic populations, although the size of the campaign effect may differ by race/ethnicity. Evidence is insufficient to determine whether campaign outcomes differ by socioeconomic status and population density. Youth are more likely to recall and think about advertising that includes personal testimonials; a surprising narrative; and intense images, sound, and editing. Evidence in support of using a health consequences message theme is mixed; an industry manipulation theme may be effective in combination with a health consequences message. Research is insufficient to determine whether advertising with a secondhand smoke or social norms theme influences youth tobacco use. Conclusion . Our recommendation is to develop antitobacco campaigns designed to reach all at-risk youth, which can be effective across racial/ethnic populations. Research priorities include assessing campaign influence among lower socioeconomic status (SES) and rural youth, disentangling the effects of message characteristics, and assessing the degree to which this body of evidence may have changed as a result of changes in youth culture and communication technology.

    ABSTRACT: Background: In 2009, the U. S. Food and Drug Administration was required to mandate that graphic health warning labels be placed on cigarette packages and advertisements. Purpose: To assess public support in the U. S. for graphic health warning labels from 2007 to 2012. Methods: Data from 17,498 respondents from 13 waves of the National Adult Tobacco Survey, a list-assisted random-digit-dial survey, were used. Overall support for graphic health warning labels, as well as support by smoking status, and by sociodemographics and smoker characteristics are estimated. Analyses were conducted in 2014. Results: Since 2007, a majority of the public overall has been in favor of labels. Support increased significantly among the public overall and among non-smokers from 2007 through 2009 (p<0.001), after which it remained flat. Among smokers, support levels increased from 2007 through 2011 (p<0.001), but decreased significantly from 2011 through 2012 (p<0.001). Support was high regardless of smoking status, although among smokers, support varied by level of smoking, interest in quitting, and whether labels were seen as an important reason to quit. Support varied by sociodemographic characteristics, particularly among smokers. Younger, less-affluent, and less-educated smokers supported labels at higher levels than their counterparts. Conclusions: A majority of U. S. residents support graphic health warning labels for cigarette packs, though support among smokers declined after 2011.

    ABSTRACT: Disparities in tobacco use and smoking cessation by race/ethnicity, education, income, and mental health status remain despite recent successes in reducing tobacco use. It is unclear to what extent media campaigns promote cessation within these population groups. This study aims to (1) assess whether exposure to antitobacco advertising is associated with making a quit attempt within a number of population subgroups, and (2) determine whether advertisement type differentialy affects cessation behavior across subgroups. We used data from the New York Adult Tobacco Survey (NY-ATS), a cross-sectional, random-digit-dial telephone survey of adults aged 18 or older in New York State conducted quarterly from 2003 through 2011 (N = 53,706). The sample for this study consists of 9,408 current smokers from the total NY-ATS sample. Regression methods were used to examine the effect of New York State's antismoking advertising, overall and by advertisement type (graphic and/or emotional), on making a quit attempt in the past 12 months. Exposure to antismoking advertising was measured in two ways: gross rating points (a measure of potential exposure) and self-reported confirmed recall of advertisements. This study yields three important findings. First, antismoking advertising promotes quit attempts among racial/ethnic minority smokers and smokers of lower education and income. Second, advertising effectiveness is attributable in part to advertisements with strong graphic imagery or negative emotion. Third, smokers with poor mental health do not appear to benefit from exposure to antismoking advertising of any type. This study contributes to the evidence about how cessation media campaigns can be used most effectively to increase quit attempts within vulnerable subgroups. In particular, it suggests that a general campaign can promote cessation among a range of sociodemographic groups. More research is needed to understand what message strategies might work for those with poor mental health.

    ABSTRACT: Objective To identify unmet research needs of state and community tobacco control practitioners pertaining to electronic nicotine delivery systems (ENDS or e-cigarettes) that would inform policy and practice efforts at the state and community levels, and to describe ENDS-related research and dissemination activities of the National Cancer Institute-funded State and Community Tobacco Control Research Initiative. Methods To determine specific research gaps relevant to state and community tobacco control practice, we analysed survey data collected from tobacco control programmes (TCPs) in all 50 US states and the District of Columbia (N=51). Survey items covered a range of ENDS issues: direct harm to users, harm of secondhand vapour, cessation, flavours, constituents and youth access. Results There is no ENDS topic on which a majority of state TCP managers feel very informed. They feel least informed about harms of secondhand vapour while also reporting that this information is among the most important for their programme. A majority (N=31) of respondents indicated needs for research on the implications of ENDS products for existing policies. Conclusions TCP managers report that ENDS research is highly important for practice and need research-based information to inform decision making around the inclusion of ENDS in existing tobacco control policies. For optimal relevance to state and community TCPs, research on ENDS should prioritise study of the health effects of ENDS use and secondhand exposure to ENDS vapour in the context of existing tobacco control policies.

    ABSTRACT: This study reports consumer reactions to the graphic health warnings selected by the Food and Drug Administration to be placed on cigarette packs in the United States. We recruited three sets of respondents for an experimental study from a national opt-in e-mail list sample: (i) current smokers aged 25 or older, (ii) young adult smokers aged 18–24 and (iii) youth aged 13–17 who are current smokers or who may be susceptible to initiation of smoking. Participants were randomly assigned to be exposed to a pack of cigarettes with one of nine graphic health warnings or with a text-only warning statement. All three age groups had overall strong negative emotional (ß = 4.7, P < 0.001 for adults; ß = 4.6, P < 0.001 for young adults and ß = 4.0, P < 0.001 for youth) and cognitive (ß = 2.4, P < 0.001 for adults; ß = 3.0, P < 0.001 for young adults and ß = 4.6, P < 0.001 for youth) reactions to the proposed labels. The strong negative emotional and cognitive reactions following a single exposure to the graphic health warnings suggest that, with repeated exposures over time, graphic health warnings may influence smokers’ beliefs, intentions and behaviors.

    ABSTRACT: Objectives: We tested the impact of banning tobacco displays and posting graphic health warning signs at the point of sale (POS). Methods: We designed 3 variations of the tobacco product display (open, enclosed [not visible], enclosed with pro-tobacco ads) and 2 variations of the warning sign (present vs absent) with virtual store software. In December 2011 and January 2012, we randomized a national convenience sample of 1216 adult smokers and recent quitters to 1 of 6 store conditions and gave them a shopping task. We tested for the main effects of the enclosed display, the sign, and their interaction on urge to smoke and tobacco purchase attempts. Results: The enclosed display significantly lowered current smokers' (B = -7.05; 95% confidence interval [CI] = -13.20, -0.91; P < .05) and recent quitters' (Β = -6.00, 95% CI = -11.00, -1.00; P < .01) urge to smoke and current smokers' purchase attempts (adjusted odds ratio = 0.06; 95% CI = 0.03, 0.11; P < .01). The warning sign had no significant main effect on study outcomes or interaction with enclosed display. Conclusions: These data show that POS tobacco displays influence purchase behavior. Banning them may reduce cues to smoke and unplanned tobacco purchases.

    ABSTRACT: Cigarette taxation is effective in reducing tobacco use in the USA. However, these benefits are reduced when taxes are unpaid. Cigarette trafficking (ie, the illegal importation of cigarettes into a high-tax jurisdiction from a lower-tax jurisdiction) is well documented in high-tax places like New York City (NYC), but the extent of trafficking in other northeastern cities is relatively unknown. To estimate the extent of cigarette trafficking in Boston, NYC, Philadelphia, Providence and Washington, DC, and project the benefits of reducing cigarette trafficking for recouping lost taxes and reducing smoking in these cities. Littered cigarette packs were collected from a random sample of Census tracts in five US cities. Data collection yielded 1439 total littered packs. The share of cigarette packs bearing proper local, known non-local, foreign or unknown, or no tax stamp was calculated for each city. These data were used to estimate tax revenue recovery if cigarette trafficking could be eliminated. We also estimated the extent to which eliminating cigarette trafficking would reduce cigarette consumption. Overall, 58.7% of packs did not have a proper local tax stamp, and 30.5-42.1% were attributed to trafficking. We estimate that eliminating cigarette trafficking would result in declines in youth smoking prevalence ranging from negligible in low-tax cities like Philadelphia to up to 9.3% in higher-tax NYC. We estimate that these five cities could recoup $680-729 million annually in cigarette tax revenue if cigarette trafficking was eliminated. Reducing cigarette trafficking would increase the effectiveness of tobacco taxes in reducing smoking and generate additional tax revenue, particularly in higher-taxed cities. Federal action to reduce cigarette trafficking, such as a track-and-trace system, is needed.

    ABSTRACT: We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002-2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p < .01). Greater coverage of smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%-7% higher in 2009. Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking.

    ABSTRACT: Abstract Purpose . Examine effects of exposure to two types of cessation advertisements on changes in cessation-related outcomes. Design . Experimental data from a nationally representative, longitudinal sample of smokers, collected in three waves over 4 weeks. Setting . National. Subjects . Three thousand and two adult U.S. smokers aged 18+ completed baseline and follow-up interviews at 2 and 4 weeks, from December 2010 to February 2011. Intervention . Six randomly assigned conditions consisting of repeated exposure to cessation advertisements: why-to-quit advertisements featuring emotional, personal testimonies (1: WTQ-T) or graphic images (2: WTQ-G); how-to-quit advertisements (3: HTQ), a combination of both (4: WTQ-T + HTQ; 5: WTQ-G + HTQ), and no-ad condition (6: control). Measures . Cessation-related beliefs, attitudes, intentions, and quitting behavior. Analysis . Multivariable ordinary least squares and logistic regressions testing whether exposure to antitobacco television advertisements were associated with changes in tobacco-related outcomes. Results . Exposure to WTQ-T or WTQ-G advertisements, both alone and combined with HTQ advertisements, elicited positive change in beliefs, attitudes, and intentions as compared to controls. Smokers in three of four WTQ conditions were substantially more likely to have quit smoking at 4 weeks than controls (odds ratios range from 5.9 to 10.1, p < .05 or better). No effects were found for the HTQ-only condition. Conclusion . Exposure to WTQ advertisements markedly increases the odds that a smoker will quit in the study period, suggesting positive movement toward successful, long-term cessation. HTQ advertisements did not enhance advertising effectiveness and may not be suitable as a primary message strategy.

    ABSTRACT: OBJECTIVE:: Quantify the degree to which changes in state-level adult smoking prevalence subsequently influence youth smoking prevalence. DESIGN:: Analysis of data from the Tobacco Use Supplement to the Current Population Survey (TUS-CPS) collected from 1995 to 2006 and the National Youth Tobacco Survey (NYTS) collected from 1999 to 2006. SETTING AND PARTICIPANTS:: Adults 25 years or older who completed the TUS-CPS and youth in middle and high school who completed the NYTS. MAIN OUTCOME MEASURES:: Current smoking among middle and high school students as a function of the change in state-level adult smoking, controlling for individual-level sociodemographic characteristics and state-level tobacco control policy variables. RESULTS:: Among middle school students, declines in state-level adult smoking rates are associated with lower odds of current smoking (P < .05), and each doubling of the decline in adult smoking rates is associated with a 6.0% decrease in youth smoking. Among high school students, declines in state-level adult smoking rates are not associated with current smoking. Higher cigarette prices were associated with lower odds of smoking among middle and high school students. Greater population coverage by smoke-free air laws and greater funding for tobacco control programs were associated with lower odds of current smoking among high school students but not middle school students. Compliance with youth access laws was not associated with middle or high school smoking. CONCLUSION:: By quantifying the effect of changes in state-level adult smoking rates on youth smoking, this study enhances the precision with which the tobacco control community can assess the return on investment for adult-focused tobacco control programs.

    ABSTRACT: CONTEXT:: Exposure to retail tobacco marketing is associated with youth smoking, but most studies have relied on self-reported measures of exposure, which are prone to recall bias. OBJECTIVE:: To examine whether exposure to retail cigarette advertising, promotions, and retailer compliance is associated with youth smoking-related outcomes using observational estimates of exposure. DESIGN:: Data on retail cigarette advertising and promotions were collected from a representative sample of licensed tobacco retailers in New York annually since 2004. County-level estimates of retail cigarette advertising and promotions and retailer compliance with youth access laws were calculated and linked to the New York Youth Tobacco Survey, administered to 54 671 middle and high school students in 2004, 2006, and 2008. Regression models examined whether cigarette advertising, promotions, and retailer compliance were associated with youth's awareness of retail cigarette advertising, attitudes about smoking, susceptibility to smoking, cigarette purchasing behaviors, and smoking behaviors. RESULTS:: Living in counties with more retail cigarette advertisements is associated with youth having positive attitudes about smoking (odds ratio [OR] = 1.10, 95% confidence interval [CI] = 1.03-1.19, P < .01). Living in counties with more retail cigarette promotions is associated with youth current smoking (OR = 1.57, 95% CI = 1.01-2.44, P < .05). Living in counties with higher retailer compliance with youth access laws is associated with higher odds of youth being refused cigarettes when attempting to buy in stores (OR = 1.12, 95% CI = 1.01-1.25, P < .05) and lower odds of retail stores being youth's usual source of cigarettes (OR = 0.88, 95% CI = 0.80-0.97, P < .01). CONCLUSIONS:: Strong retailer compliance programs and policies that eliminate cigarette advertising and promotions may help reduce youth smoking.

    ABSTRACT: Objectives: We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). Methods: We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. Results: Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. Conclusions: Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking.

    ABSTRACT: To isolate the independent influence of exposure to smoking and other adult content in the movies on youth smoking uptake. We used discrete time survival analysis to quantify the influence of exposure to smoking and other adult content in the movies on transitioning from (1) closed to open to smoking; (2) never to ever trying smoking; and (3) never to ever hitting, slapping, or shoving someone on two or more occasions in the past 30 days. The latter is a comparative outcome, hypothesized to have no correlation with exposure to smoking in the movies. Assessed separately, both exposure to smoking imagery and exposure to adult content were associated with increased likelihood of youth becoming open to smoking (OR = 1.09, 95% CI: 1.04-1.15 and OR = 1.10, 95% CI: 1.04-1.17) and having tried smoking (OR = 1.06, 95% CI: 1.00-1.12 and OR = 1.06, 95% CI: 1.00-1.13). Both measures were also separately associated with aggressive behavior (OR = 1.09, 95% CI: 1.04-1.14 and OR = 1.09, 95% CI: 1.04-1.15). A very high correlation between the two measures (0.995, p<0.000) prevented an assessment of their independent effects on smoking initiation. Although exposure to smoking in the movies is correlated with smoking susceptibility and initiation, the high correlation between exposure to smoking in the movies and other adult content suggests that more research is needed to disentangle their independent influence on smoking.

    ABSTRACT: The aim of the study was to assess the relative effectiveness of cessation, secondhand smoke and other tobacco control television advertisements in promoting quitlines in nine states from 2002 through 2005. Quarterly, the number of individuals who used quitlines per 10 000 adult smokers in a media market are measured. Negative binomial regression analysis was used to link caller rates to market-level exposure to tobacco control television advertisements overall and by message theme. The relationship between caller rates and advertising exposure was positive and statistically significant (P < 0.001). Advertisements that focus on promoting cessation (P < 0.001), highlighting the dangers of secondhand smoke (P = 0.037), and all other tobacco countermarketing advertisements (P = 0.027) were significantly associated with quitline caller rates. For every 10% increase in exposure to cessation, secondhand smoke and other tobacco countermarketing advertisements, caller rates increased by 1.1, 0.2 and 0.4%, respectively. Caller rates significantly increased in quarters when cigarette excise tax increased (P < 0.001) and when the percentage of the population covered by comprehensive smoke-free air laws increased (P = 0.022). Although advertisements promoting cessation are the most effective in driving quitline use, other topics, such as messages highlighting the dangers of secondhand smoke, also prompt their quitlines.

    ABSTRACT: Objective: To examine the potential impact of banning tobacco displays and ads at the point of sale (POS) on youth outcomes. Methods: An interactive virtual convenience store was created with scenarios in which the tobacco product display at the POS was either openly visible (status quo) or enclosed behind a cabinet (display ban), and tobacco ads in the store were either present or absent. A national convenience sample of 1216 youth aged 13 to 17 who were either smokers or nonsmokers susceptible to smoking participated in the study. Youth were randomized to 1 of 6 virtual store conditions and given a shopping task to complete in the virtual store. During the shopping task, we tracked youth's attempts to purchase tobacco products. Subsequently, youth completed a survey that assessed their perceptions about the virtual store and perceptions about the ease of buying cigarettes from the virtual store. Results: Compared with youth in the status quo condition, youth in the display ban condition were less aware that tobacco products were for sale (32.0% vs 85.2%) and significantly less likely to try purchasing tobacco products in the virtual store (odds ratio = 0.30, 95% confidence interval = 0.13-0.67, P < .001). Banning ads had minimal impact on youth's purchase attempts. Conclusions: Policies that ban tobacco product displays at the POS may help reduce youth smoking by deterring youth from purchasing tobacco products at retail stores.

    ABSTRACT: This study supplements existing literature on the relationship between parent-child communication and adolescent drug use by exploring whether parental and/or adolescent recall of specific drug-related conversations differentially impact youth's likelihood of initiating marijuana use. Using discrete-time survival analysis, we estimated the hazard of marijuana initiation using a logit model to obtain an estimate of the relative risk of initiation. Our results suggest that parent-child communication about drug use is either not protective (no effect) or - in the case of youth reports of communication - potentially harmful (leading to increased likelihood of marijuana initiation).

    ABSTRACT: Antismoking campaigns can be effective in promoting cessation, but less is known about the dose of advertising related to behavioral change among adult smokers, which types of messages are most effective, and effects on populations disproportionately affected by tobacco use. To assess the impact of emotional and/or graphic antismoking TV advertisements on quit attempts in the past 12 months among adult smokers in New York State. Individual-level data come from the 2003 through 2010 New York Adult Tobacco Surveys. The influence of exposure to antismoking advertisements overall, emotional and/or graphic advertisements, and other types of advertisements on reported attempts to stop smoking was examined. Exposure was measured by self-reported confirmed recall and market-level gross rating points. Analyses conducted in Spring 2012 included 8780 smokers and were stratified by desire to quit, income, and education. Both measures of exposure to antismoking advertisements are positively associated with an increased odds of making a quit attempt among all smokers, among smokers who want to quit, and among smokers in different household income brackets (<$30,000 and ≥$30,000) and education levels (high-school degree or less education and at least some college education). Exposure to emotional and/or graphic advertisements is positively associated with making quit attempts among smokers overall and by desire to quit, income, and education. Exposure to advertisements without strong negative emotions or graphic images had no effect. Strongly emotional and graphic antismoking advertisements are effective in increasing population-level quit attempts among adult smokers.
