Factors Associated With Abstinence Among Young Adult Smokers Enrolled in a Real-world Social Media Smoking Cessation Program.

Social media platforms are promising to provide smoking cessation support. This study aimed to identify baseline factors associated with cigarette smoking abstinence among young adult smokers enrolled in a real-world social media-based smoking cessation program. We analyzed data from young adult smokers (aged 18-30 years) participating in a publicly available Facebook-based smoking cessation program serving the San Francisco Bay Area. The analytic sample consisted of 248 participants who completed both the baseline and follow-up surveys at 3 months. Multivariable logistic regression analysis determined baseline factors significantly associated with self-reported 7-day cigarette smoking abstinence at 3 months. Participants were race/ethnically diverse, well-educated, and 47.6% reported LGB + sexual identity. Those who reported dual use of cigarettes and e-cigarettes in the past 30 days (vs. cigarette use only), current alcohol users (vs. non-users), and those aged 25-30 years (vs. 18-24 years) were significantly less likely to report 7-day abstinence at 3 months. Non-daily smokers (vs. daily smokers) and those with high desire to quit smoking (vs. low to moderate desire) were more likely to report abstinence. Results also showed reduction in the percentage of e-cigarette and other tobacco product use among participants. Social media interventions may be more effective for young adult non-daily smokers and those with high desire to quit smoking. Smoking cessation programs may help reduce use of other tobacco products among treatment-seeking smokers. Smoking cessation interventions for young adults need to explicitly address dual use of cigarettes and e-cigarettes and use of alcohol. Findings of this study highlight the need for future interventions to address dual use of cigarettes and e-cigarettes and use of alcohol to improve cigarette smoking abstinence outcomes. The reduction in the use of other tobacco products among program participants indicates that social media smoking cessation programs may exert a broader positive influence on overall tobacco consumption. The large number of LGB+ smokers participating in the program suggests social media is a promising cessation channel for this hard-to-reach group, warranting further study.

Prevalence and correlates of flavored novel oral nicotine product use among a national sample of youth

BackgroundFlavored novel oral nicotine products (ONP), such as pouches, gum, lozenges, tablets, and gummies, have recently entered the US market but have not been authorized for smoking cessation. This study assessed the prevalence and correlates of ONPs in a national sample of youth who smoked little filtered cigars or cigarillos (LCCs) or were susceptible to LCCs. MethodsWe conducted a national online survey from September-October 2022, as part of a study to develop cigar warnings among youth. Those aged 15–20 years old who reported using (ever or current) or susceptibility to little filtered cigars or cigarillos (LCCs) were eligible. Descriptive statistics and chi-square analyses assessed the prevalence of flavored ONP use and associations with other past 30-day tobacco product use and participant characteristics. ResultsApproximately one-fifth (17.1 %) of the sample (n = 680) reported past month flavored ONP use. Any past month tobacco use was correlated with past month flavored ONP use (ps < 0.001), increasing from 17.1 % in the overall sample to 26.8 % among those reporting e-cigarette use, 41.4 % (LCCs), 47.8 % (waterpipe tobacco), 61.8 % (large cigars), and 69.1 % (smokeless tobacco). The number of products used in the past month was significantly associated with higher odds of ONPs in the past month in a multivariable logistic regression model (aOR2.26; 95 % CI: 1.92, 2.65). DiscussionAlmost one-fifth of participants who use or are susceptible to cigar use in our national sample of youth use ONPs. Dual/poly use of other tobacco products and ONPs among youth suggests that many of these youth may be addicted to nicotine. Additional surveillance and regulation of ONPs that exhibit enticing characteristics, such as flavors, kid-friendly formulations, and targeted marketing/branding may be needed.

Predictors of Quitting Dual Use of Electronic Cigarettes and Cigarettes During Pregnancy.

Background and Aims: There is limited research surrounding dual maternal use of cigarettes and electronic cigarettes (e-cigarettes). We aimed to assess predictors of maternal quitting of cigarettes, e-cigarettes, and both during late pregnancy. Materials and Methods: We analyzed dual use (n = 4,006) and exclusive e-cigarette use (n = 1,685) among mothers using data from the 2016 to 2019 phase of the Pregnancy Risk Assessment Monitoring Systems (PRAMS), a nationally representative sample of the United States. Dual use and exclusive e-cigarette use were defined based on use reported during the 3 months before pregnancy and quitting was assessed during the last 3 months of pregnancy. Multinomial and binomial logistic regression models estimated the odds ratios and 95% confidence intervals for predictors of quitting status among mothers who reported dual use and exclusive e-cigarette use, respectively. Separate predictor analyses were conducted in the dual and exclusive e-cigarette use groups to see predictors of quitting e-cigarettes, cigarettes, or both. Results: The highest proportion of mothers who used cigarettes and e-cigarettes before pregnancy quit both during late pregnancy (46.2%), followed by those who quit e-cigarette use only (26.5%) and those who quit cigarette use only (6.6%). Among mothers who reported dual use, those who were African American or Asian, of Hispanic ethnicity, consumed alcohol before pregnancy, had higher education, were married, had diabetes, had higher annual household income, had nongovernmental health insurance, had more prenatal care visits, had a higher frequency of e-cigarette use before pregnancy, had a lower frequency of cigarette use before pregnancy, and smoked hookah around pregnancy had a higher likelihood of quitting both cigarette and e-cigarette use during late pregnancy. Conclusions: Quitting use of cigarettes and/or e-cigarettes was fairly common among mothers who reported dual use or e-cigarette use only. Sociodemographics, pregnancy characteristics, and use of other tobacco products predicted quitting use of both cigarettes and e-cigarettes during late pregnancy.

Prevalence and Covariates of Electronic Cigarette Use among Students Aged 13-15 Years in the Philippines: 2019 Global Youth Tobacco Survey.

Electronic cigarette use is growing in popularity and accessibility among youth in the Southeast Asia region. We analyzed data on 6670 students, aged 13-15 years, from the Philippines' 2019 Global Youth Tobacco Survey. Prevalence estimates and 95% confidence intervals (CI) were estimated for current use (i.e., past 30 days), ever use, and awareness of e-cigarettes. Chi-square tests compared prevalence differences between groups. Multiple logistic regression models assessed factors associated with e-cigarette use while controlling for sociodemographic characteristics, current use of other tobacco products, and secondhand smoke exposure. Prevalence of current e-cigarette use was 14.1% (95% CI = 12.4%, 15.8%), ever use was 24.6% (95% CI = 22.4%, 26.9%), and awareness was 75.5% (95% CI = 73.0%, 78.0%). Current use of any other tobacco products and exposure to secondhand smoke at home, school, or other public places were positively associated with current and ever use of e-cigarettes. Boys and youth living in Luzon or Mindanao had higher odds of current e-cigarette use compared to girls and youth in Visayas. Findings indicated that one in four Philippine students aged 13-15 years ever used e-cigarettes and one in seven currently use e-cigarettes. This study highlights the importance of implementing evidence-based strategies, including relevant tobacco control policies.

Performance of the Heaviness of Smoking Index in Indian Settings.

Background and objective The heaviness of smoking index (HSI) is a popular tool to assess nicotine dependence in clinical and community settings. Low cigarette consumption and concurrent use of other tobacco products raise concerns about its validity in Indian settings. This study explores the performance of HSI in Indian settings. Methods This study analyzed daily manufactured cigarette smoker data from the cross-sectional Global Adult Tobacco Surveys (GATS) from its first (GAST-1, 2009) and second waves (GATS-2, 2016), both of which were available in the public domain. The HSI scores were calculated based on the number of cigarettes smoked per day (CPD) and time to first smoke (TTFS) after waking up among the current daily cigarette users. This study examined the utility of the HSI scale in Indian settings by estimating the predictability of low dependence on quit attemptsand quit intentions using the likelihood ratio parameter. Results About nine in 10 cigarette users in India consumed less than 10 cigarettes per day, yielding a low score on the HSI scale for most of the daily cigarette users. The majority of daily cigarette smokers scored ≤ 1 (low dependence) on the HSI scale both in GATS-1 and GATS-2, irrespective of their exclusive cigarette use status. The absolute value and the 95% confidence limit of positive likelihood ratios (falling below and above one) suggest that the predictability of low dependence on quit attempts and quit intention in the Indian setting is limited. Conclusions The utility of the HSI scale in assessing nicotine dependence among cigarette users in India is limited. This may be attributed to low average cigarette consumption, concurrent use of various tobacco products, and the sociocultural milieu of Indian smokers. This highlights the need for a new rapid nicotine dependence scale tailored to the specific patterns of tobacco use behavior prevalent in the Indian context.

What e-cigarette factors determine oral epithelial DNA damage in consumers?

Study participants were divided equally into three groups being exclusive vapers (never smokers), current exclusive smokers and non-users. Brush biopsy samples of oral epithelial cells were collected. DNA damage quantification was assessed using LA-QPCR, and analysis interrogated a 12.2 kb region of the DNA polymerase beta gene (POLB). An additional gene, hypoxanthine phosphoribosyltransferase 1 (HPRT), was also interrogated for validity. Enzyme-linked immunosorbent assay (ELISA) was used to measure plasma cotinine levels. Breath monitoring was measured using Bedfont Micro Smokerlyzer in order to quantify exhaled CO and %COHb levels in participants. 72 subjects, consisting of both males and females of diverse ages, races and ethnicities, were recruited. Comprehensive interviews alongside biochemical studies were used to verify smoking and vaping status. Participants classified as vapers reported a minimum use of e-cigarettes three times weekly for 6 months, with no use of cigarettes or tobacco products in their lifetime. Smokers reported cigarette consumption for a minimum of three times weekly for at least 12 months, less than five vaping sessions ever and no use of other tobacco products in the previous 6 months. Participants reporting no or less than five uses of e-cigarettes or tobacco products were classified as non-users. Former smokers, vapers and those who were dual or poly users of e-cigarettes, cigarettes or tobacco products were excluded. R environment for statistical computing (RStudio), was used for data analysis. The Shapiro-Wilk test was used to evaluate the distribution of data. Student's t test allowed comparison of all variables between two groups (vapers and nonusers, smokers and nonusers, or vapers and smokers), specifically DNA damage levels. A one-way Analysis of Variance (ANOVA) followed by a post hoc Tukey HSD test allowed comparison of damage in three or more groups (heavy vapers, light vapers, and nonusers, as well as heavy smokers, light smokers, and nonusers). DNA damage was also analysed in this manner when assessing e-cigarette device type, liquid type or in non-users. Pearson correlation coefficient analysis allowed examination of relationships between different variables. Mean levels of DNA damage in the POLB gene was 2.6-fold higher in vapers (p = 0.005) and 2.2-fold higher in smokers (p = 0.020), when compared to non-users. On comparing POLB gene DNA damage in vapers versus smokers, the results were not statistically significant (p = 0.522). Comparing DNA damage in the HPRT gene, levels were much higher in vapers (p = 0.029) and smokers (p = 0.033) versus non-users. Similarly to the POLB gene, DNA damage levels in the HPRT gene in vapers versus smokers were not statistically significant (p = 0.578). When assessing volume of e-cigarette liquid or smoking pack years, levels of DNA damage in increased in the POLB gene in a dose-dependent manner between 'light' and 'heavy' users versus non-users (F = 4.571, p = 0.0156 | Tukey's HSD p = 0.0195 in vapers, F = 4.368, p = 0.0185 | Tukey's HSD p = 0.0135 in smokers). Vaping device type was investigated showing mean level of DNA damage in the oral cells of pod device users was 3.3-fold higher compared to non-users (F = 3.886, p = 0.0152 | Tukey's HSD p = 0.0216). This was followed by a 2.6-fold increase in oral cell DNA damage in Mod device users, and a 1.6-fold increase in multiple device users. Levels of DNA damage was higher in those who consume sweet-flavoured e-liquid (F = 3.238, p = 0.0146 | Tukey's HSD p < 0.05), followed by vapers of multiple flavours, mint or menthol and tobacco, and fruit flavours. No correlation was found between DNA damage of oral cells and cumulative nicotine consumption in vapers (r = 0.3189, p = 0.1288). Plasma cotinine levels, a validated maker of tobacco in cigarettes and e-cigarettes, were not significantly different between vapers and smokers (p = 0.607), but were significantly higher compared to non-users (p < 0.0001). Whist compared to non-users, vapers had similar levels of CO and %COHb, smokers showed significantly increased levels (p = 0.0005 and p = 0.0002, respectively). Based on the results of this study, there is evidence to support a dose-dependent formation of DNA damage in oral cells in those vapers who have never smoked cigarettes, and in those exclusive cigarette smokers. Additionally, e-cigarette device type and flavour, may also determine levels of DNA damage.

Estimating Prevalence of Premium or Traditional Cigar Use and User Characteristics Based on Varying Definitions of Use.

Premium cigar use is infrequent compared with the use of other tobacco products, including other cigar types (eg, cigarillos), though current measurement methods for premium cigar use have limitations. Accordingly, prevalence estimates from existing surveillance studies likely underestimate the true prevalence of premium cigar use. Using an online convenience sample of adults (ages 18-45 years) surveyed in February 2022, we examined premium or traditional cigar prevalence and characterized users based on four definitions of use: (1) past-year use, (2) past 30-day use, (3) use every day or some days, and (4) use every day, some days, or rarely, using a novel, one-item measure. We examined demographics, cigar use behaviors, and other tobacco product use for each definition and conducted sensitivity analyses using cigar brands. Prevalence estimates ranged from 1.8% using Definition 3 to 11.6% using Definition 1. Regardless of definition, premium or traditional cigar users were largely male, white, and aged 25-45 years. A large proportion of users based on Definition 3 were aged 25-34 years, had a regular premium cigar brand, smoked cigars on more than one day in the past month, used cannabis in the past month, and reported perceiving premium cigars as less harmful compared with cigarettes. Prevalence estimates of premium or traditional cigar use varied by more than fivefold based on the definition of use and user characteristics varied by definition. Existing national surveys are likely underestimating the prevalence and patterns of premium cigar use. Given that the negative health effects of premium cigars vary based on how the cigars are used (eg, frequency or duration), as well as co-use with other tobacco products and substances (eg, alcohol and cannabis), accurate measurement of these products is important for understanding patterns of use and their impact on public health.

Accurately classifying cannabis blunt use as tobacco-cannabis co-use versus exclusive cannabis use

BackgroundHistorically, blunt use constituted tobacco-cannabis co-use based on the products available for creating blunts (e.g., hollowed-out cigars filled with cannabis). With the introduction of tobacco-free blunt wraps (e.g., hemp wraps), blunt use now may constitute tobacco-cannabis co-use or exclusive cannabis use. We examined adolescents’ use of tobacco and tobacco-free blunt products and highlighted how misclassification of tobacco-cannabis co-use versus exclusive cannabis use may occur if products used to make blunts are not assessed. Methods4855 students from eight Connecticut high schools completed an online survey in 2022. Use of tobacco products for making blunts (e.g., cigarillos, tobacco blunt wraps) and tobacco-free blunt wraps were assessed as was the use of other tobacco products (e.g., e-cigarettes, cigarettes, hookah). The analytic sample comprised 475 students who endorsed lifetime blunt use. ResultsTobacco-free blunt wraps (72.6%) were the most popular product for making blunts, followed by cigarillos (56.5%), tobacco blunt wraps (49.2%), and large cigars (13.0%). When classified into mutually exclusive groups, students reported exclusive tobacco-free blunt use (32.3%), exclusive tobacco product blunt use (27.4%), or use of both tobacco product and tobacco-free blunts (40.3%). Among those exclusively using tobacco-free blunts, 13.4% endorsed no tobacco product use. ConclusionsTobacco-free blunt wraps were very popular among high school adolescents, highlighting the importance of assessing products used for making blunts. Assuming that blunts contain tobacco without considering tobacco-free blunts can lead to misclassification of blunt use as tobacco-cannabis co-use when it actually reflects exclusive cannabis use, potentially leading to inflated estimates of tobacco use.

Reactions to using other nicotine and tobacco products instead of menthol cigarettes: A qualitative study of people who smoke menthol cigarettes in the United States

The US Food and Drug Administration is considering banning menthol cigarettes, which could result in some people who smoke menthol cigarettes switching to other tobacco products (OTPs). This qualitative study explored reactions to using OTPs instead of menthol cigarettes. People who smoke menthol cigarettes (N=40) completed a behavioral economic assessment of the effects of menthol cigarette price increases on OTP purchasing. At the highest price, most participants could not afford menthol cigarettes. Instead, they could purchase non-menthol cigarettes, little cigars/cigarillos (LCCs), e-cigarettes, smokeless tobacco, or medicinal nicotine, or they could abstain from tobacco use. Participants used the OTPs they purchased for three days. During follow-up sessions, participants (n=35) completed semi-structured interviews discussing their purchasing-decisions and experiences using OTPs instead of menthol cigarettes. Interviews were analyzed using reflexive thematic analysis methods. Factors influencing purchasing decisions included flavor, price, prior use of OTPs, interest in trying new OTPs, and perceived ability to satisfy nicotine cravings. Participants described positive experiences using e-cigarettes including the “refreshing” menthol flavor, ability to use in places where cigarettes are prohibited, and convenience of use relative to smoking. Among those using non-menthol cigarettes, many reported they were acceptable but less satisfying products compared to menthol cigarettes while others reported negative reactions to them such as tasting like “cardboard”. Reactions to smoking LCCs were mostly unfavorable but participants said it gave them “something to light”. Multiple considerations may affect switching to OTPs in light of pending menthol cigarette regulation including the availability of menthol-flavored alternatives and (dis)satisfaction with OTPs.

Identifying high school smokers likely to persist in smoking at age 31

ObjectiveQuitting smoking by the mid-30 s conveys important health benefits. Yet, although many smokers attempt to quit, few succeed. Identification of the characteristics of adolescent smokers most likely to continue smoking between ages 30 and 40 could help target early cessation efforts. Our objectives in this study were to (i) describe the course of smoking in a population-based sample of high school smokers into their 20 s and 30 s, and (ii) identify distal predictors of past-year cigarette smoking at age 31. MethodsData at ages 17 (in 11th grade), 20, 24 and 31 were drawn from a 20-year longitudinal study of students ages 12–13 at inception, from 10 high schools in Montréal, Canada. Associations between 11 smoking-related characteristics measured in 11th grade and past-year smoking at age 31 were estimated in multivariable logistic regression models. ResultsAmong 244 11th grade smokers (67.4% female; 41% daily smokers), past-year smoking was reported by 71% at age 20, 68% at age 24, and 52% at age 31. Only 12% reported abstinence at ages 20, 24 and 31. Females were less likely than males to smoke at age 31. Parental smoking while the smoker was in 11th grade, use of other tobacco products, longer time since smoking onset, weekly or daily smoking, monthly cigarette consumption, and perceived nicotine addiction predicted past-year smoking at age 31. ConclusionsIn addition to preventive interventions, cessation programs targeting novice smokers in high school as soon as they begin smoking, are warranted.

Investigating Tobacco Product Use Behavior Among Students Attending High Schools Within the Cherokee Nation Reservation.

Tobacco use is the leading cause of death in the United States and youth prevention is key to reducing tobacco use. American Indian/Alaska Native (AI/AN) individuals have a higher prevalence of tobacco use compared to other populations. This paper aims to evaluate the prevalence of tobacco products among youth within the Cherokee Nation reservation. Data from the 2019 Cherokee Nation Youth Risk Behavior Survey (YRBS) was used to analyze the prevalence of tobacco use (cigarettes, smokeless tobacco, electronic cigarettes, cigars, and ≥ 2 products) among students within Cherokee Nation. Weighted frequency and percentages were obtained for variables and 95% confidence intervals were computed using Taylor linearization variance estimators. Binary associations between variables were examined using the Rao-Scott Chi-square test. There were 1475 high students who participated in the 2019 Cherokee Nation YRBS. Males were more likely to report the use of smokeless tobacco and ≥ 2 products than females. Twelfth graders had a higher prevalence of reported e-cigarette use compared to lower grades. AI/AN students had a higher prevalence of current use of cigarettes and ≥ 2 products compared to other groups. The use of marijuana and alcohol was positively associated with the use of all tobacco products. Depression was also positively associated with the use of all products excluding smokeless tobacco. Grade, age, depression, and current use of other tobacco products, marijuana, and alcohol were associated with greater electronic cigarette intensity levels. Using the results, tribal and local organizations can promote evidence-based interventions that focus on reducing tobacco use among youth.

The Role of Cigarillo Flavor in the Co-Use of Cigarillos and Cannabis among Young Adults

Background: Research suggests flavor facilitates cigarillo use, but it is unknown if flavor impacts patterns of co-use of cigarillos and cannabis (“co-use”), which is common among young adult smokers. This study’s aim was to determine the role of the cigarillo flavor in co-use among young adults. Methods: Data were collected (2020-2021) in a cross-sectional online survey administered to young adults who smoked ≥2 cigarillos/week (N = 361), recruited from 15 urban areas in the United States. A structural equation model was used to assess the relationship between flavored cigarillo use and past 30-day cannabis use (flavored cigarillo perceived appeal and harm as parallel mediators), including several social-contextual covariates (e.g., flavor and cannabis policies). Results: Most participants reported usually using flavored cigarillos (81.8%) and cannabis use in the past 30 days (“co-use”) (64.1%). Flavored cigarillo use was not directly associated with co-use (p = 0.90). Perceived cigarillo harm (β = 0.18, 95% CI = 0.06, 0.29), number of tobacco users in the household (β = 0.22, 95% CI = 0.10, 0.33), and past 30-day use of other tobacco products (β = 0.23, 95% CI = 0.15, 0.32) were significantly positively associated with co-use. Living in an area with a ban on flavored cigarillos was significantly negatively associated with co-use (β = -0.12, 95% CI = -0.21, −0.02). Conclusions: Use of flavored cigarillos was not associated with co-use; however, exposure to a flavored cigarillo ban was negatively associated with co-use. Cigar product flavor bans may reduce co-use among young adults or have a neutral impact. Further research is needed to explore the interaction between tobacco and cannabis policy and use of these products.

Clinicopathological and Treatment Patterns of Combined Small-Cell Lung Carcinoma with Future Insight to Treatment: A Population-Based Study.

Primary lung cancer is the most common cause of cancer-related mortality in the United States (US). Approximately 90% of lung cancers are associated with smoking and the use of other tobacco products. Based on histology, lung cancers are divided into small-cell lung carcinomas (SCLCs) and non-small-cell lung carcinomas (NSCLCs). Most SCLCs are of the pure subtype, while the rare combined SCLCs contain elements of both small-cell and non-small-cell morphologies. This study sought to evaluate the demographics, clinical factors, molecular abnormalities, treatment approaches, and survival outcomes with combined SCLC and NSCLCs. Data on 2126 combined SCLC patients was extracted from the Surveillance Epidemiology and End Result (SEER) database from 2000 to 2018. Data extracted for analyses included age, sex, race, tumor size, tumor location, metastasis status, stage at diagnosis, treatment received, and treatment outcomes. Multivariate analysis was performed using Statistical Product and Service Solutions (SPSS) software. The patients had a median age of 68 years; 43.9% of the patients were female and 56.1% were male; 84.5% were White and 11.7% were African Americans. The majority of patients had a poorly differentiated disease at 29.6%; 17% were undifferentiated, 3.2% were moderately differentiated, and 0.8% were well differentiated. Chemotherapy was the most common treatment modality (45.3%); 17% underwent surgery only, 10.3% underwent surgery followed by adjuvant chemotherapy, and 10% underwent radiation after surgery. Five-year cancer-specific survival was 15.2% with surgery alone, and combined surgery and chemotherapy provided the highest percentages (38.3% and 34.7%, respectively). Females had significantly higher 1- and 5-year cancer-specific survival rates compared to males (59.3% and 29.9% vs. 48.0% and 23.7, respectively; p < 0.001). Well-differentiated tumors had significantly higher survival compared to other gradings (p < 0.001). Survival decreased as tumor staging moved distally from localized to regional to distant (p < 0.001). Metastasis to bone, liver, brain, and lung significantly decreased survival in comparison to patients who did not have any metastasis (p < 0.001). Females had significantly shorter survival compared to their counterparts when metastasis was to the bone, brain, or liver (p < 0.001). Multivariate analysis identified male sex (Hazard Ratio (HR) = 1.2), undifferentiated grade (HR = 1.9), regional extent of disease (HR = 1.7), distant extent of disease (HR = 3.7), and metastasis to liver (HR = 3.5) as variables associated with worse survival. Combined SCLC is overall very rare. However, the frequency of presentation with combined SCLC is on the rise, in part due to improvements in diagnostic techniques. Despite advances in therapies, treating combined SCLC is challenging, and novel therapies are not utilized, owing to low rates of targetable mutations. Combined SCLC has higher survival rates if well differentiated.

Predictors of past-year e-cigarette use among young adults

Understanding the underpinnings of e-cigarette use among young adults is critical to addressing increasing uptake. We identified predictors of past-year e-cigarette use among young adults in Montreal, Canada. Data on potential predictors were available for 714 young adults participating in the ongoing Nicotine Dependence in Teens Study at age 20 in 2007–08. Past-year e-cigarette use was measured at age 30 in 2017–20. Each potential predictor was studied in a separate multivariable logistic regression model controlling for age, sex, and educational attainment. Male sex, friends who smoke, cigarette smoking, use of other tobacco products, alcohol use, use of marijuana, and impulsivity predicted past-year e-cigarette use. Higher educational attainment and very good/excellent self-rated health were protective. Program and policy makers will need to consider these predictors of e-cigarette use in the design of clinical and public health interventions targeting e-cigarette use in young adults.

E-cigarette use among high school students in the United States prior to the COVID-19 pandemic: Trends, correlates, and sources of acquisition

Detailed description of the prevalence and sources of e-cigarettes among youth is needed to inform effective regulatory policies. We used the Youth Risk Behavior Surveillance System data (2015–2019) to assess trends in current (past-30-day-use) and frequent (≥10 days in past-30-days) e-cigarette use among United States high schoolers before the COVID-19 pandemic. First, we assessed trends overall and then stratified by participants’ sociodemographic characteristics, use of other tobacco products, and experiences of psychosocial stress. We also evaluated past year quit attempts and the changing sources of e-cigarettes.Our sample size was 41,021 (15,356–2015; 12,873–2017; 12,792–2019). The prevalence of current e-cigarette use increased from 24.0% (95%CI:21.9%–26.3%) in 2015 to 32.7% (30.4%–35.1%) in 2019. The proportion of current users who reported frequent use also increased significantly from 22.6% (20.4%–24.8%) to 45.4% (42.7%–48.2%). Thus, an increasing proportion of US high school students who use e-cigarettes reported frequent use, indicating greater nicotine dependence. The increase in current and frequent e-cigarette use was more pronounced in youth who reported other substance use and psychosocial stressors such as bullying. Between 2017 and 2019, there was a decline in the proportion of youth who bought e-cigarettes online (6.9% to 3.2%) or from convenience stores (22.0% to 16.6%). Conversely, there was an increase in the proportion who borrowed (34.5% to 40.1%) or purchased e-cigarettes through other people (10.7% to 18.0%), indicating that most youth are evading age-related restrictions by obtaining e-cigarettes from other people. Finally, a considerable proportion of youth tobacco users are making quit attempts; 47.6% (45.1%–50.1%) in 2019.

Waterpipe smoking: Results from a population-based study in Qatar.

INTRODUCTIONWaterpipe smoking is common in the Eastern Mediterranean Region and is becoming more prevalent in Qatar. To better plan waterpipe smoking control strategies we aimed to: 1) determine the prevalence of waterpipe smoking and explore its patterns in Qatar; 2) describe the knowledge, attitudes, and practices related to smoking behaviors; 3) recognize locations of waterpipe smoking and symptoms experienced during waterpipe sessions; and 4) evaluate the frequency of waterpipe smoking and the initiation age.METHODSWe analyzed the data of a 7921 population-based survey of adults aged ≥18 years (nationals and expatriates), conducted in Qatar between March and December 2019. Out of 7105 surveys collected, 6904 were complete and included in the analysis.RESULTSOf the 6904, 570 (8.3%; 95% CI: 7.7–9.0) were waterpipe tobacco smokers, 425 (10.6%) males and 145 (5.1%) females. The highest prevalence of waterpipe smoking was reported among people aged 18–24 years (10.6%). Of the 575 waterpipe smokers, 56.3% (n=324) were exclusive waterpipe smokers. Use of other tobacco products among waterpipe smokers was higher among Qataris (52.3%) than expatriates (37.7%). Waterpipe cafés were the most common location for waterpipe smoking, however, females preferred restaurants; 83.3% reported that waterpipe smoking is harmful, while 39.3% considered that it is less harmful than cigarette smoking.CONCLUSIONSWaterpipe smoking prevalence is considerably high in Qatar, the second form of tobacco used. The formulation of new policies and enforcement of regulatory restrictions on waterpipe smoking are essential to reduce its uptake. Expansion in tobacco cessation services for women and poly-tobacco users is needed.

Correlates of tobacco product initiation among youth and young adults between waves 1–4 of the population assessment of tobacco and Health (PATH) study (2013–2018)

IntroductionWhile risk factors for cigarette smoking among youth and young adults are well-documented, less is known about the correlates of initiation of other tobacco products. This study aims to provide estimates and correlates of initiation among U.S. youth and young adults. MethodsData on youth aged 12–17 (n = 10,072) and young adults aged 18–24 (N = 5,727) who provided information on cigarettes, electronic nicotine delivery systems (ENDS), cigars, pipe, hookah and smokeless tobacco use in Wave 1 (W1: 2013–2014)-Wave 4 (W4: 2016–2018) of the nationally-representative PATH Study were used to calculate ever use initiation and correlates of initiation by W4. ResultsNearly 6 million youth and 2.5 million young adults used tobacco for the first time between W1-W4. Approximately one quarter of youth and young adult ENDS never users initiated ENDS between W1-W4 of the PATH Study. Among youth, use of other tobacco products, ever substance use, and high externalizing problems were associated with initiation of most products. Among young adults, use of other tobacco products and ever substance use were associated with initiation of most products. In both youth and young adults, Hispanics were more likely to initiate hookah use than their non-Hispanic White counterparts. While male sex was a risk factor for most tobacco product initiation across both age groups, it was not associated with hookah initiation. ConclusionsCigarette and non-cigarette products shared many correlates of initiation, although there are noteworthy demographic differences. Findings can help tailor product specific interventions to reach populations at risk during preliminary stages of use.

Perceived stress and E-cigarette use during emerging adulthood: A longitudinal examination of initiation, progression, and continuation

E-cigarettes are the most commonly used tobacco product among youth and young adults in the US. Limited research has examined how stress impacts e-cigarette use among young people. We examine the longitudinal associations between perceived stress scale (PSS) score and e-cigarette use behaviors among a diverse cohort of emerging adults. We analyzed two waves of data collected in Fall 2019 (baseline) and Spring 2020 (6-month follow-up) of the Texas Adolescent Tobacco and Marketing Surveillance (TATAMS) system. Participants were classified into three mutually exclusive subsamples at baseline: (1) n = 1177 never e-cigarette users; (2) n = 806 ever but not current (past 30-day) e-cigarette users (i.e., ever users); and (3) n = 257 current (past 30-day) e-cigarette users. Three multivariate logistic regression models examined the relationship between PSS at baseline and: (1) initiation among never users; (2) progression to current use among ever users; and (3) continuation among current users, at 6-month follow-up. PSS scores were standardized using z-scores. Models controlled for race/ethnicity, sex, age, ever marijuana use, and ever use of other tobacco products. Mean age ranged from 18.6 to 19.4 among cohorts. Risk for e-cigarette progression among ever users (aOR: 1.30; 95%CI: 1.01–1.69) and e-cigarette continuation among current users (aOR: 1.33 (95%CI: 1.01–1.75) increased with each unit increase in PSS score at baseline. PSS at baseline was not associated with e-cigarette initiation among never users. PSS predicted greater risk of e-cigarette progression and continuation but not initiation among a diverse cohort of emerging adults. E-cigarette prevention and cessation strategies should consider perceived stress an important risk factor for e-cigarette use during emerging adulthood.

A Daily Assessment Study of Smoking Cessation After a Head and Neck Cancer Diagnosis.

This intensive longitudinal study describes key events in the process of smoking cessation after a new head and neck cancer (HNC) diagnosis. Prior longitudinal studies show some cancer patients quit, while others continue to smoke, but details about the pattern in which these discrete outcomes arise are scarce. This study is meant to help rectify this gap in the literature. Participants were 42 HNC patients who reported current smoking at enrollment. Participants were recruited from an outpatient oncology clinic and completed a baseline questionnaire prior to begin a 30-day daily assessment. Few participants (9.52%) achieved 30-day continuous abstinence from smoking. On average, participants reported 9.64 ± 11.93 total days of abstinence. Nearly, all (94.44%, n = 34) participants made at least one quit attempt, with an average of 16.94 ± 11.30 quit attempt days. Fewer participants were able to achieve a 24-hour quit attempt (52.78%, n = 19), with a corresponding average of 5.50 ± 8.69 24-hour days. The median time to first 24-hour quit attempt was 13 days after enrollment. Based on smoking behavioral patterns, participants were categorized into five groups, the most common being "persistent attempters," which involved unsuccessful quit attempts throughout the study. Only 45% of participants (n = 19) used evidence-based treatment, the most common being cessation medication. This intensive longitudinal study found that cancer diagnosis can spur a lot of efforts to quit smoking. Unfortunately, this study suggests that many quit attempts are short lived, possibly a result of an absence or insufficient use of evidence-based treatments. For adults who are current smokers at the time of cancer diagnosis, there is a high likelihood of persistent cigarette smoking and use of other tobacco products in the weeks and months after a cancer diagnosis. Furthermore, this study shows that while a lot of quit attempts may occur, few are successful, which may be partly attributable to the low use of evidence-based tobacco treatment. Future research with cancer patients should aim to identify predictors of quit attempts and abstinence as well as treatment utilization.
