Cumulative Exposure to E-Cigarette Coupons and Changes in E-Cigarette Use Among U.S. Adults.

INTRODUCTION: Coupons are an effective, frequently used tobacco marketing strategy. This study examined prospective associations between cumulative exposure to e-cigarette coupons and changes in e-cigarette use among U.S. adults. METHODS: Data were from a representative U.S. adult cohort (n=19,824) in the Population Assessment of Tobacco and Health Study (waves [W] 2, 3, 4, and 5), collected from October 2014 to November 2019. Analysis was conducted in 2022. Four logistic regression models examined associations of a number of waves for which participants received e-cigarette coupons during W2-W4 with changes in e-cigarette use: W2 never use to W5 current use (initiation); W2 current nondaily use to W5 daily use (progression); W2 current use to W5 former use (cessation), and W2 former use to W5 current use (return-to-use). RESULTS: Overall, 66.1% of U.S. adults never used e-cigarettes, 10.6% currently used e-cigarettes, and 23.4% formerly used e-cigarettes at W2. The average number of waves for which participants received e-cigarette coupons during W2-W4 was 0.13: 0.10 among W2 individuals who never used e-cigarettes, 0.30 among individuals who currently used e-cigarettes on a nondaily basis, 0.50 among individuals who currently used e-cigarettes, and 0.17 among individuals who formerly used e-cigarettes. Receiving coupons at increased waves was associated with (1) greater odds of initiation (AOR=1.58, 95% CI=1.26-1.97); (2) lower odds of cessation (AOR=0.78, 95% CI=0.67-0.91); and (3) increased odds of return-to-use (AOR=1.39, 95% CI=1.14-1.69). Findings did not differ by W2 cigarette smoking status. CONCLUSIONS: E-cigarette coupons may encourage and sustain e-cigarette use. Policies restricting e-cigarette coupons may curb e-cigarette use.

Tobacco Smoke Exposure and Sleep Duration among U.S. Adolescents.

OBJECTIVES: Tobacco smoke exposure (TSE) and poor sleep are public health problems with their own set of consequences. This study assessed whether TSE was associated with sleep duration among U.S. adolescents. METHOD: We conducted a secondary analysis of 2013-2018 National Health and Nutrition Examination Survey data including 914 nontobacco-using adolescents ages 16-19 years. TSE measures included cotinine and self-reported home TSE groups including no home TSE, thirdhand smoke (THS) exposure, and secondhand smoke (SHS)+THS exposure. Sleep duration was assessed in hours and categorically as insufficient sleep (recommended hours). Weighted multiple linear regression and multinomial regression models were conducted. RESULTS: Adolescents with higher log-cotinine levels had higher number of sleep hours (ß = 0.31, 95%CI = 0.02,0.60) and were at increased odds of reporting excess sleep (AOR = 1.41, 95%CI = 1.40,1.42), but were at reduced odds of reporting insufficient sleep (AOR = 0.88, 95%CI = 0.87,0.89). Compared to adolescents with no home TSE, adolescents with home THS exposure and home SHS+THS exposure were at increased odds of reporting insufficient sleep (AOR = 2.27, 95%CI = 2.26,2.29; AOR = 2.75, 95%CI = 2.72,2.77, respectively) and excess sleep (AOR = 1.89, 95%CI = 1.87,1.90; AOR = 5.29, 95%CI = 5.23,5.34, respectively). CONCLUSIONS: TSE may affect insufficient and excess sleep duration among adolescents. Eliminating TSE may promote adolescent respiratory and sleep health.

Awareness of electronic cigarette industry practices and their associations with anti-electronic cigarette attitudes among susceptible US young adults.

BACKGROUND: Public education exposing cigarette industry practices have been effective in changing attitudes and preventing smoking among young people. It is unclear how much young adults are aware of e-cigarette industry practices, and how this awareness relates to anti-e-cigarette attitudes. We examined demographic correlates of awareness of e-cigarette industry practices and anti-e-cigarette attitudes, and the association between awareness of these practices with anti-e-cigarette attitudes. METHODS: A US sample of young adults aged 18-30 years who do not use commercial tobacco products but are susceptible to e-cigarette use were cross-sectionally surveyed through online panel services from August 2021 to January 2022. Respondents reported their demographics, awareness of cigarette industry practices, awareness of e-cigarette industry practices and their level of agreement with four anti-e-cigarette attitude statements. We used multivariable linear regressions to examine demographic associations and the relationship between awareness of e-cigarette industry practices with each anti-e-cigarette attitude, adjusting for demographics and awareness of cigarette industry practices. RESULTS: Generally, Hispanic and Black young adults (vs White) and those with

Electronic cigarette use and cigarette smoking associated with inadequate sleep duration among U.S. young adults.

OBJECTIVE: Nicotine use can influence inadequate sleep, but less is known about the associations of exclusive and dual use of electronic cigarettes (e-cigarettes) with combustible cigarettes in U.S. young adults. This study assessed the associations between current exclusive e-cigarette use, exclusive cigarette smoking, and dual e-cigarette and combustible cigarette use and inadequate sleep duration among U.S. young adults. METHODS: We performed a secondary analysis of 2020 Behavioral Risk Factor Surveillance System (BRFSS) data including 13,978 U.S. young adults ages 18-24 years. Inadequate sleep duration was assessed categorically using the National Sleep Foundation's age-specific recommendations that define <7 h as inadequate sleep. Weighted logistic regression models were performed while adjusting for participants' sex, race/ethnicity, education level, annual household income level, body mass index, current physical activity, mental health status, disability status, current alcohol use, and current smokeless tobacco use. RESULTS: Concerning use patterns, 11.8% of young adults were exclusive e-cigarette users, 4.7% were exclusive cigarette smokers, and 3.8% were dual e-cigarette and combustible cigarette users. Exclusive e-cigarette users (adjusted odds ratio [AOR] = 1.41, 95% confidence interval [CI] = 1.16-1.72), exclusive cigarette smokers (AOR = 1.63, 95%CI = 1.22-2.18), and dual product users (AOR = 2.03, 95%CI = 1.44-2.86) were at increased odds of having inadequate sleep duration compared to non-users, while adjusting for the covariates. Additionally, dual product users were at increased odds (AOR = 1.52, 95%CI = 1.06-2.19) of reporting inadequate sleep duration compared to exclusive e-cigarette users, while adjusting for the covariates. CONCLUSIONS: Current e-cigarette and cigarette use may influence inadequate sleep among U.S. young adults. Tobacco cessation efforts may encourage increased sleep health.

Concern for Police Brutality, Societal Discrimination, and School Shootings and Subsequent Cigarette and Cannabis Use in Los Angeles County Hispanic and Non-Hispanic White Youth: a Longitudinal Study.

OBJECTIVE: Examine if concerns for police brutality, societal discrimination, and school shootings relate to subsequent cigarette and cannabis use among Hispanic and non-Hispanic White (NHW) youth. Hispanic youth may be particularly vulnerable to such concern. METHODS: Data are from the University of Southern California's Happiness and Health Survey, a prospective cohort study, which followed Hispanic (N = 1007) and NHW (N = 251) students from ten inner-city and suburban high schools in Los Angeles County, starting from 2013 until 2019. Participants reported concern, worry, and stress levels regarding police brutality, societal discrimination, and school shootings. Four categories were created to indicate levels of each concern variable over time (consistently low, decreased, increased, and consistently high). Associations with past-30-day cannabis, blunt, THC-oil, and cigarette use in 2019 were assessed. Separate models for each racial/ethnic category were used. RESULTS: Among Hispanic participants, reporting consistently high concern about police brutality (vs. consistently low concern) was associated with higher odds to subsequently smoke cannabis (aOR = 1.69, 95% CI = 1.18-2.40), smoke blunts (aOR = 1.63, 95% CI = 1.11-2.39), and vape THC-oil (aOR = 1.67, 95% CI = 1.14-2.44). Hispanic participants who reported consistently high concern for societal discrimination also had higher odds (vs. consistently low concern) to subsequently smoke blunts (aOR = 1.54, 95% CI = 1.04-2.29) and vape THC-oil (aOR = 1.65, 95% CI = 1.12-2.43). Among NHW participants, increasing concern over school shootings (vs. consistently low concern) was associated with higher odds to subsequently smoke cannabis (aOR = 2.98, 95% CI = 1.08-7.70). CONCLUSIONS: Concerns for police brutality, societal discrimination, and school shootings were associated with cannabis use especially among Hispanic participants. Providing Hispanic youth with healthy coping strategies may reduce cannabis use.

Exploring Young Adults' Beliefs About Cigar Smoking by Susceptibility: A Belief Elicitation Study.

INTRODUCTION: Young adults are at risk for cigar smoking, which is associated with cancers and pulmonary and cardiovascular diseases. Little is known about young adults' beliefs about smoking cigarillos, little filtered cigars, and large cigars, and how these beliefs may vary across cigar types and by cigar susceptibility. AIMS AND METHODS: The larger study surveyed a U.S. sample of young adults (18-30 years old) who never used tobacco products (n = 948) through Qualtrics online panel services in August 2021-January 2022. We assessed participants' susceptibility to using different cigar types. Participants were randomly assigned to open-ended questions about one of the three cigar types to elicit behavioral, normative, and control beliefs. We conducted thematic analysis to code emergent themes within each belief and examined the frequency of reported themes at the intersection of cigar type and cigar susceptibility. RESULTS: Cigar susceptible participants reported positive behavioral beliefs (eg, anticipated relaxation, mood regulation, being cool), friends as supportive referents, and easy-to-smoke control beliefs (eg, high accessibility, low cost) more frequently than non-susceptible participants. Varied frequency by cigar type also emerged. For example, cigarillo and little filtered cigar features were mentioned more frequently as easy-to-smoke control beliefs, while low accessibility was reported more frequently as a hard-to-smoke control belief for large cigars. CONCLUSIONS: Findings identify salient beliefs about cigarillo, little filtered cigar, and large cigar smoking among young adult tobacco never-users. Future research should investigate the potential importance of these beliefs in cigar smoking susceptibility and initiation among young adults, and their potential utility in prevention research. IMPLICATIONS: This thematic analysis identified salient beliefs about cigarillos, little filtered cigars, and large cigars among a U.S. young adult sample, and differentiated emergent beliefs by cigar susceptibility status and by cigar type. Given the lack of cigar smoking prevention media campaigns, identifying these beliefs is the one of the first steps in developing effective cigar smoking prevention strategies. Future quantitative studies are needed to confirm the relationships between these beliefs and smoking initiation of each cigar type to further inform the types of beliefs to be targeted in strategic communication and help prevent cigar smoking initiation among susceptible young adults.

Associations for subgroups of E-cigarette, cigarette, and cannabis use with asthma in a population sample of California adolescents.

Knowledge about the respiratory health consequences of adolescents' use of tobacco products with cannabis remains limited. We studied whether e-cigarettes, combustible cigarettes, and cannabis were independently associated with asthma in a population-based sample of 150,634 public high school students (10th and 12th graders), drawn in a two-stage design to be representative of the state of California in 2019-2020. Measures were obtained for use of e-cigarettes, combustible cigarettes, and cannabis; motives for use (three substances); method of use (for cannabis); ever being diagnosed with asthma; and having an asthma attack in past 12 months. Cross-classification indicated Nonuse for 64% of the sample; 15% Dual E-cigarette/Cannabis Use; 10% Exclusive Cannabis Use; 5% Exclusive E-cigarette Use; and 5% Triple Use. Multinomial logistic regression with a three-level criterion variable, controlling for age, sex, parental education, race/ethnicity, and three types of household use showed that compared with Nonuse, odds of Lifetime Asthma (vs. Never Had) was elevated for Triple Use (AOR = 1.14, CI 1.06-1.24), Dual E-cigarette/Cannabis Use (1.17, 1.12-1.23), Exclusive Cannabis Use (1.17, 1.11-1.23), and Exclusive E-cigarette Use (1.10, 1.02-1.18). Similar results were noted for Recent Asthma. Among persons who had used cannabis, 88% of the Triple group and 74% of the Dual E-cigarette/Cannabis group reported both smoking and vaping cannabis. Thus, co-occurrence of e-cigarette and cannabis use was a common pattern among adolescents in this study, and subgroups of cannabis and e-cigarette use showed similar associations with asthma. Preventive approaches should highlight the health implications of exclusive or combined e-cigarette and cannabis use.

Financial hardship during the COVID-19 pandemic and increased receipt of commercial tobacco discount coupons among US adults who use commercial tobacco.

INTRODUCTION: Many individuals experienced financial hardship during the COVID-19 pandemic; yet commercial tobacco (CT) sales increased in the USA. We examined how experiencing financial hardships relates to increased CT discount coupon reception during the pandemic. METHODS: A nationally representative sample of 1700 US adults who used CT during the 12 months prior to the survey were surveyed online during January to February 2021. Participants reported if they had received more discount coupons for various CT products during (compared with before) the pandemic. They also reported whether they experienced six different types of financial hardships since the pandemic, and the total number of hardships experienced was counted. Weighted multivariable logistic regressions were used to examine the associations between financial hardships and increased coupon reception, adjusting for demographics and CT product use. RESULTS: During the first 10-11 months of the pandemic, 21.3% of US adults who used CT during the 12 months prior to the survey reported receiving more CT discount coupons. Experiencing financial hardship during the pandemic was associated with higher odds of receiving more coupons for all types of CT products: every additional count of financial hardship was associated with higher odds of increased reception of discount coupons for all CT products (adjusted odds ratios ranging from 1.13 to 1.23 across products). CONCLUSIONS: Over one-fifth of US adults who used CT received more discount coupons during the pandemic. Those facing financial hardships had higher discount coupon reception, suggesting potential targeted marketing to financially vulnerable individuals by the tobacco industry.

Cumulative cigarette discount coupon exposure and trajectories of cigarette smoking: a longitudinal analysis in US adults.

INTRODUCTION: Exposure to cigarette discount coupons is associated with short-term increase in cigarette smoking; however, long-term impact is unclear. This study examined associations of cumulative exposure to cigarette coupons with trajectories of cigarette smoking in US adults. METHODS: Data were from the US Population Assessment of Tobacco and Health Study Adult Surveys (n=19 824; waves 2-5). We examined the number of waves participants received cigarette discount coupons/promotions during waves 2-4 and smoking behaviours at wave 5. Weighted logistic multivariable regression models were used, adjusting for wave 2 demographics and stratified by wave 2 smoking status. RESULTS: Among wave 2 adults who never smoked, each increment wave of exposure to cigarette discount coupons was associated with greater odds of wave 5 current smoking (adjusted OR (aOR)=2.09, 95% CI 1.24-3.52). Among wave 2 adults who smoked daily, each wave of coupon exposure was associated with lower odds of quitting smoking at wave 5 (aOR=0.67, 95% CI 0.62-0.73). Among wave 2 adults who had quit smoking, each increment wave of exposure was associated with greater odds of wave 5 current smoking (aOR=1.61, 95% CI 1.41-1.85). Additionally, women (vs men) and adults with lower socioeconomic status (SES) (vs higher SES) were more frequently exposed to cigarette coupons for a higher number of waves (p<0.05). DISCUSSION: Exposure to cigarette coupons exhibited a dose-response relationship with changes in cigarette smoking behaviours over time, promoting smoking progression and hindering smoking cessation especially among women and people with lower SES. Prohibiting these coupons can be an important tobacco control strategy.

U.S. young adults' awareness of the Master Settlement Agreement and cigarette industry practices and their associations with electronic cigarette industry and health risk perceptions.

BACKGROUND: The lawsuit that led to the U.S. Master Settlement Agreement (MSA) exposed the cigarette industry's deceptive marketing practices, which changed population perceptions about the cigarette industry and helped prevent cigarette smoking. The cigarette industry now owns many electronic cigarette (e-cigarette) companies and make their own e-cigarettes. Given that the MSA occurred in previous decades, many millennial and generation Z young adults may not know about the MSA and the cigarette industry's marketing practices. It is unknown whether awareness about the MSA and cigarette industry practices may influence these young adults' e-cigarette industry and e-cigarette health risk perceptions, which may inform e-cigarette prevention efforts. METHODS: Cross-sectional data were collected from a U.S. sample of tobacco-naïve young adults, 18-30 years-old, susceptible to e-cigarette use (n = 1,329) through an online panel service in August 2021-January 2022. Participants reported their demographic characteristics, awareness of the MSA, awareness of cigarette industry practices, e-cigarette industry perceptions, and e-cigarette health risk perceptions. We examined the relationships between awareness of the MSA and cigarette industry practices with e-cigarette industry and e-cigarette health risk perceptions using multivariable linear regressions, adjusted for demographic characteristics. RESULTS: Overall, 36.2%, 24.1%, and 39.3% of participants had heard of the MSA and knew a lot about it, had heard of the MSA, but did not know much about it, and did not hear of the MSA, respectively. On average, participants were aware of 5.2 (SD = 3.0) of the 11 cigarette industry practices included. Hearing about the MSA and knowing a lot about it and awareness of more cigarette industry practices were associated with less positive e-cigarette industry and higher e-cigarette health risk perceptions, whereas having heard of the MSA but not knowing much about it was associated with more positive e-cigarette industry and lower e-cigarette health risk perceptions. CONCLUSIONS: Findings suggest that increasing comprehensive awareness of the MSA and cigarette industry practices may influence young adults' e-cigarette-related perceptions, and may importantly prevent detrimental information gaps about the cigarette industry. Future research should investigate the potential impact of increasing awareness of the MSA and cigarette industry practices in changing e-cigarette-related perceptions, which may help prevent e-cigarette use.

COVID-19 Stay-At-Home Orders and Secondhand Smoke in Public Housing.

INTRODUCTION: This study aimed to better understand the inequitable impact of the pandemic by examining the associations between stay-at-home orders and indoor smoking in public housing, measured by ambient particulate matter at the 2.5-micron threshold, a marker for secondhand smoke. METHODS: Particulate matter at the 2.5-micron threshold was measured in 6 public-housing buildings in Norfolk, VA from 2018 to 2022. Multilevel regression was used to compare the 7-week period of the Virginia stay-at-home order in 2020 with that period in other years. RESULTS: Indoor particulate matter at the 2.5-micron threshold was 10.29 µg/m3 higher in 2020 (95% CI=8.51, 12.07) than in the same period in 2019, a 72% increase. Although particulate matter at the 2.5-micron threshold improved in 2021 and 2022, it remained elevated relative to the level in 2019. CONCLUSIONS: Stay-at-home orders likely led to increased indoor secondhand smoke in public housing. In light of evidence linking air pollutants, including secondhand smoke, with COVID-19, these results also provide further evidence of the disproportionate impact of the pandemic on socioeconomically disadvantaged communities. This consequence of the pandemic response is unlikely to be isolated and calls for a critical examination of the COVID-19 experience to avoid similar policy failures in future public health crises.

Racial/Ethnic Disparities in Vicarious and Direct COVID-19-Related Discrimination and Vigilance.

INTRODUCTION: The high visibility of COVID-19-related discrimination underscores the importance of understanding the psychological harms associated with vicariously and directly experiencing such incidents. In this observational study, both vicariously and directly experienced COVID-19-related discrimination and their association with heightened concerns about discrimination and vigilance were examined in U.S. adults who use commercial tobacco. METHODS: Data were from a nationally representative sample of adults who currently or formerly used commercial tobacco products (N=1,700; mean age=43 years) from an online survey panel administered in January-February 2021 (analyzed in 2021-2022). Participants reported vicariously and directly experienced COVID-19-related discrimination, concern about experiencing such discrimination, and heightened vigilance. Weighted multivariable linear and logistic regression models were used to examine the associations among these variables. RESULTS: Overall, 69% of individuals reported exposure to vicarious COVID-19-related discrimination, and 22% reported directly experiencing COVID-19-related discrimination. Asian, Hispanic, and Black individuals reported higher levels of concern and vigilance than White individuals (p<0.05). Vicariously and directly experienced COVID-19-related discrimination was independently associated with concern about experiencing COVID-19-related discrimination in the entire sample and within each racial and ethnic group (p<0.05). This concern was associated with increased vigilance (p<0.05) and was stronger in those exposed to vicarious COVID-19-related discrimination than in those who were not (p<0.05). CONCLUSIONS: COVID-19-related discrimination may undermine the psychological well-being of those who are exposed to it vicariously as well as those who experience it directly and may also make individuals feel vulnerable and unsafe. Interventions to prevent and reduce the impact of COVID-19-related discrimination may have wide-reaching societal benefits.

Heated Tobacco Products: Awareness, Beliefs, Use and Susceptibility among US Adult Current Tobacco Users, 2021.

Limited data exist on the awareness, beliefs, and use of heated tobacco products (HTPs). Data from 1583 U.S. adult (age ≥ 21 years) current tobacco users were collected in 2021. Participants self-reported HTP awareness, beliefs, use, and susceptibility, as well as current tobacco product use and sociodemographics. We used weighted logistic and multinomial regression models to explore their associations. Overall, 23.6% were aware of, 8.9% had ever used, and 3.0% currently used HTPs. Younger individuals (vs. 61+ years), those with annual income $50,000+ (vs. <$50,000), and those currently using electronic vaping products (vs. non-users) were more likely to be aware of, to have ever used, and to currently be using HTPs (p < 0.05). Black individuals (vs. White) were more likely to report ever and current HTP use (p < 0.05). Current cigarette smoking was not associated with HTP awareness and use (p > 0.05). Holding favorable HTP beliefs was associated with susceptibility to and more advanced HTP use statuses (p < 0.05). Sociodemographics associated with HTP use may reflect HTP marketing strategies. The lack of association with cigarette smoking suggests HTPs may be unlikely cigarette substitutes. Addressing favorable HTP-related beliefs may prevent dual use.

Nicotine Pouch: Awareness, Beliefs, Use, and Susceptibility among Current Tobacco Users in the United States, 2021.

Little is known about awareness, beliefs, and use of nicotine pouches (NPs). Data from 1583 U.S. adult (age ≥ 21 years) current tobacco users were collected in 2021. Respondents self-reported NP awareness, beliefs, use, and susceptibility as well as current tobacco product use and socio-demographics. We used weighted logistic and multinomial regression models to explore the associations between these variables. Overall, 46.6% of U.S. adult current tobacco users were aware of, 16.4% had ever used, and 3.0% currently used NPs. Younger individuals (vs. 61+ years) were more likely to have ever heard of NPs, while Black individuals (vs. White) were less likely to have ever heard of NPs. Individuals younger than 45 years (vs. 61+ years) and those using smokeless tobacco products (vs. non-users) were more likely to have ever used NPs. Additionally, younger than 45 years (vs. 61+ years) and current use of certain tobacco products (e.g., smokeless) were associated with current NP use. Holding favorable beliefs about NPs was associated with susceptibility to and more advanced NP use statuses (p < 0.05). Continuous surveillance of NP use and beliefs is important.

Financial challenges and hardship during the COVID-19 pandemic and tobacco expenditure minimizing strategies among U.S. adult commercial tobacco users.

INTRODUCTION: Commercial tobacco (CT) users employ tobacco expenditure minimizing strategies (TEMS) to manage their CT expenditures. We examined how financial challenges and hardships during the COVID-19 pandemic relate to increases in TEMS use. METHODS: Data from a nationally representative sample of 1,700 U.S. adult recent former and current CT users were collected from an online panel during January-February 2021. Participants reported if they had increased use of eight TEMS to save money on CT since the pandemic, and experienced financial challenges (e.g., losing a job) and hardships (e.g., not having enough money to pay for food). The number of financial hardships experienced was counted (range: 0-6). Weighted multivariable logistic regression models were used to examine the associations between financial challenges and hardships and increased TEMS use, adjusting for demographics. RESULTS: Since the COVID-19 pandemic, three TEMS showed the largest increase in use by U.S. adult current and recent former CT users: cutting back (22.4%), finding less expensive places to purchase (15.6%), and buying by bulk (15.5%). Many financial challenges and hardships were consistently associated with increased uses of TEMS. Furthermore, every additional count of financial hardships was associated with higher odds of increasing use of each TEMS (AORs ranging between 1.12 and 1.23). CONCLUSIONS: Many CT users increased TEMS use to manage their CT expenditures when facing financial challenges and hardships during the pandemic. This could hinder CT cessation and promote relapse. Prohibiting certain TEMS (e.g., discount coupon and price promotions) may promote CT cessation among this financially vulnerable group.

Correlates of Anticipated Responses to Cigar Price Increase Among U.S. Adults Who Smoke Cigars.

We examined the prevalence and correlates of anticipated responses to hypothetical cigar price increases. Data are from a 2021 representative sample of U.S. adults who reported past-30-day cigar use (n = 454; mean age = 39.8 years). Weighted multivariable logistic regressions assessed the correlates of behavior change responses. If cigar price increased, 77.2% intend to pay more, 44.7% intend to reduce use, and 39.9%, 37.7%, and 17.1% intend to use other tobacco, cannabis, and cheaper cigars, respectively. Those who smoked cigarillos (vs. other cigars) had higher odds of intending to pay more (adjusted odds ratio [AOR] = 2.73; 95% confidence interval [CI] = [1.41, 5.29]) and use other tobacco (AOR = 2.35; 95%CI = [1.26, 4.36]). Those who smoked within 5 min of waking (vs. >60 min) had higher odds of intending to use cheaper cigars (AOR = 5.19, 95%CI = [1.38, 19.46]). Almost half of U.S. adults who report past-30-day cigar use may reduce cigar smoking in response to price increases, though behavioral response may depend on cigar type smoked and tobacco dependence.

Sources of Tobacco Smoke Exposure and Their Associations With Serum Cotinine Levels Among US Children and Adolescents.

INTRODUCTION: We assessed tobacco smoke exposure (TSE) levels based on private and public locations of TSE according to race and ethnicity among US school-aged children ages 6-11 years and adolescents ages 12-17 years. AIMS AND METHODS: Data were from 5296 children and adolescents who participated in the National Health and Nutrition Examination Survey (NHANES) 2013-2018. Racial and ethnic groups were non-Hispanic white, black, other or multiracial, and Hispanic. NHANES assessed serum cotinine and the following TSE locations: homes and whether smokers did not smoke indoors (home thirdhand smoke [THS] exposure proxy) or smoked indoors (secondhand [SHS] and THS exposure proxy), cars, in other homes, restaurants, or any other indoor area. We used stratified weighted linear regression models by racial and ethnic groups and assessed the variance in cotinine levels explained by each location within each age group. RESULTS: Among 6-11-year-olds, exposure to home THS only and home SHS + THS predicted higher log-cotinine among all racial and ethnic groups. Non-Hispanic white children exposed to car TSE had higher log-cotinine (ß = 1.64, 95% confidence interval [CI] = 0.91% to 2.37%) compared to those unexposed. Non-Hispanic other/multiracial children exposed to restaurant TSE had higher log-cotinine (ß = 1.13, 95% CI = 0.23% to 2.03%) compared to those unexposed. Among 12-17-year-olds, home SHS + THS exposure predicted higher log-cotinine among all racial and ethnic groups, except for non-Hispanic black adolescents. Car TSE predicted higher log-cotinine among all racial and ethnic groups. Non-Hispanic black adolescents with TSE in another indoor area had higher log-cotinine (ß = 2.84, 95% CI = 0.85% to 4.83%) compared to those unexposed. CONCLUSIONS: TSE location was uniquely associated with cotinine levels by race and ethnicity. Smoke-free home and car legislation are needed to reduce TSE among children and adolescents of all racial and ethnic backgrounds. IMPLICATIONS: Racial and ethnic disparities in TSE trends have remained stable among US children and adolescents over time. This study's results indicate that TSE locations differentially contribute to biochemically measured TSE within racial and ethnic groups. Home TSE significantly contributed to cotinine levels among school-aged children 6-11 years old, and car TSE significantly contributed to cotinine levels among adolescents 12-17 years old. Racial and ethnic differences in locations of TSE were observed among each age group. Study findings provide unique insight into TSE sources, and indicate that home and car smoke-free legislation have great potential to reduce TSE among youth of all racial and ethnic backgrounds.

Trends in Education-Related Smoking Disparities Among U.S. Black or African American and White Adults: Intersections of Race, Sex, and Region.

INTRODUCTION: Despite its overall decline in the United States, trends in cigarette smoking could vary by intersection with demographic characteristics. We explored trends in education-related disparities in current smoking among U.S. adults by race (Black or African American and White), sex, and U.S. census region. AIMS AND METHODS: Data were from U.S. civilian non-institutionalized adults (aged ≥18 years) who self-identified as Black or African American and White and participated in the 1995-2019 Tobacco Use Supplement to the Current Population Survey. We estimated average annual percent changes in current cigarette smoking by the intersections of race, sex, census region, and educational attainment. We calculated educated-related prevalence differences in current cigarette smoking by subtracting the prevalence of bachelor's degrees from that of
