Cigarillo and multiple tobacco product use and nicotine dependence in adolescents and young adults

Age of tobacco, nicotine and cannabis use initiation in Switzerland: a sequence analysis among adolescents and young adults

BACKGROUND

To explore at what age youth start using tobacco and/or nicotine products, which product is used first, product initiation sequences, and whether some socio-demographic characteristics are associated with substance use initiation.

METHODS

Data were collected from an online questionnaire disseminated through social media and professional partners, targeting youth aged 14-25 in French-speaking Switzerland in August 2022. The final sample included 1362 participants. Respondents were asked whether they had already used cigarettes, e-cigarettes, hookah, snus, or cannabis at least once in their life (yes/no) and the age of the first time was asked for each substance when the answer was positive. Additionally, participants were asked about their substance use in the past 30 days. Respondents were classified according to age at onset of each tobacco/nicotine and cannabis product, and comparisons were made based on sociodemographic variables, including gender (cisgender female/cisgender male/transgender), perceived socioeconomic status (below average/average/above average), and age.

RESULTS

Overall, in addition to those who reported no consumption, four distinct initiation profiles emerged from the classification. Cigarettes remain the most commonly used first product with an average age of 15.7 years. While cigarettes and hookah are present in all profiles, the order of first consumption varies from one profile to another, with cigarettes coming first in two profiles, hookah in one and e-cigarettes in the last. Furthermore, while the most common profile contains experimental consumption of the five products considered, some profiles do not contain cannabis, e-cigarettes and/or snus, for example. When divided by age groups, both 14-17-year-olds and 18-21-year-olds reported cigarette as their first product of initiation. Across the separate age groups (14-17, 18-21, 22-25), cigarettes consistently emerge as the primary used on average.

CONCLUSIONS

Cigarettes remain the first product to be used, but the younger the respondents, the earlier they start using e-cigarettes, and very close to cigarettes. Regarding current consumption patterns, e-cigarettes are becoming increasingly prominent.

Which reference groups matter for Taiwanese high school adolescent smoking? A card sorting study

BACKGROUND

Adolescence represents a pivotal period for the initiation of smoking behaviours. While family, peer and social groups serve as significant reference groups influencing adolescents' decision-making process, there remains a paucity of research that examines how diversified reference groups influence their smoking decisions.

OBJECTIVE

The objective is to compare normative and informative influences given by different reference groups on adolescents' smoking decision-making.

DESIGN

This study applied reference group theory and used the card sorting technique. Adolescents were presented with 16 cards portraying various reference groups and 27 cards portraying different types of reference group influences. They were asked to construct sentences as smoking-elicited and smoking-inhibited cues and ranked these influences based on their relevance to their smoking decision-making.

PARTICIPANTS

The participants were recruited from four cities in the North, Central, South and East regions of Taiwan. The study sample consisted of 297 Taiwanese 11th graders drawn from high schools, vocational high schools and night schools.

PRIMARY OUTCOME MEASURES

The most influential reference group among smokers, former smokers and never smokers.

RESULTS

Our results of multivariable logistic regression show that for current smokers, having a smoking best friend (aOR=7.58, p<0.01), having a smoking colleague (aOR=3.83, p<0.01) and participating in ceremonial dance performances (aOR=4.62, p<0.01) are more likely to smoke. Peers play an important role in providing smoking-elicited cues for current smokers. Families provided the most smoking-inhibited cues for former and never smokers. Normative influences such as encouraging adolescent smoking provided more cues for adolescents than informative influences such as releasing stress by smoking.

CONCLUSIONS

Adolescent smoking behaviour was influenced by peer norms, while former and non-smoking behaviours are associated with family norms. Therefore, tobacco prevention efforts should focus more on family-level interventions to discourage smoking initiation. Smoking cessation programmes for current smokers should address the reduction of peer pressure to smoke. Moreover, schools and community partners should collaborate to develop effective smoking cessation strategies, particularly for high-risk groups such as adolescents who involved in ceremonial dance performance.

ENDS function as a complement for cigarillos in sexual and gender minority young adult women

INTRODUCTION

Cigarillos are the second most used tobacco product among younger populations. The highest prevalence of use of cigars is among sexual and gender minority (SGM) women. Policy interventions like flavor bans and the availability of alternative tobacco products may have a disparate effect.

METHODS

The current study utilized an online store analog, The Experimental Tobacco Marketplace (ETM), to investigate the effects of cigarillo and ENDS flavor bans on tobacco product purchasing. SGM (n=72) and cisgender heterosexual (Cis-Het; n =46) women viewed conditions in which cigarillo flavors were available or unavailable and ENDS flavors available or unavailable and the interaction between the two. Mixed models were conducted on each dependent variable with condition, price, and SGM identity as predictors and nicotine dependence, annual income, and race/ethnicity as covariates. Simple linear regressions were performed to determine the substitution profile for each tobacco product. Condition showed no effect.

RESULTS

We found a main effect of price on cigarillo purchasing and a main effect of SGM identity in which SGM women purchased more ENDS than CisHet women. A complementary association between cigarillos and ENDS in which ENDS purchasing decreased as cigarillo purchasing decreased was found. This association was irrespective of flavor ban conditions and among SGM women only.

CONCLUSIONS

These results suggest that flavor availability of cigarillos and ENDS may not influence women who use cigarillos to move to another tobacco product and that women SGM cigarillo users are not likely to substitute their cigarillo smoking behavior with ENDS.

IMPLICATIONS

The results of this study suggest that SGM women are not likely to quit using cigarillos if flavors are removed from the market and instead will use unflavored products. Substituting their cigarillo use with ENDS does not appear likely given the complementary relation found between cigarillos and ENDS. The substitution patterns found for cigarettes and ENDS are not found for cigarillos and ENDS among young adult women who use cigarillos, further demonstrating the need for research on the conditions in which people who use cigarillos will decrease consumption or switch to a potentially less harmful product.

Racial and Ethnic Disparities in Adolescent Combustible Tobacco Smoking From 2014 to 2020: Declines Are Lagging Among Non-Hispanic Black Youth

INTRODUCTION

We quantified the linear trend in combustible tobacco smoking among adolescents in the United States from 2014 to 2020, and then compared these trends across racial and ethnic categories. We also tested the effect of e-cigarette use on these trends for all-youth and across racial and ethnic categories.

AIMS AND METHODS

We pooled and analyzed seven years of National Youth Tobacco Survey data for n = 124 151 middle and high school students from 2014 to 2020. Weighted logistic regression analyses calculated the annual change in combustible tobacco smoking (ie cigarettes, cigars, and hookah) from 2014 to 2020. Stratified analyses examined linear trends for non-Hispanic White (NHW), NH-Black (NHB), Hispanic/Latino, and NH-Other (NHO) youth. All-models controlled for sex, grade level, and past 30-day e-cigarette use.

RESULTS

Combustible tobacco smoking from 2014 to 2020 dropped by more than 50% for NHW youth, more than 40% for Latino and NHO youth, compared to just 16% among NHB youth. From 2014 to 2020, the odds of combustible tobacco smoking declined by 21.5% per year for NHWs, which was significantly greater than Hispanic/Latinos (17% per year; p = .025), NHOs (15.4% per year; p = .01), and NHBs (5.1% per year; p < .001), adjusting for sex, grade, and e-cigarette use. Trends and disparities in trends by race and ethnicity were observed independent of e-cigarette use.

CONCLUSIONS

Combustible tobacco smoking declined for all-youth but at significantly different rates across races and ethnicities. Notably, declines in combustible tobacco smoking are lagging among NHB youth. Interventions are critically needed to address this disparity.

IMPLICATIONS

A direct, evidence-based intervention to reduce combustible tobacco smoking among NHB youth is critically needed. Such tobacco control initiatives should follow the Best Practices for Comprehensive Tobacco Control Framework, incorporating sustainable funding for school-based intervention, public health education, and adult cessation.

Patterns and determinants of tobacco purchase behaviors among male cigarette smokers in Vietnam: A latent class analysis

INTRODUCTION

Understanding smokers' purchasing patterns can aid in customizing tobacco control initiatives aimed at reducing the tobacco smoking prevalence. Therefore, this study identified cigarette purchase behavior among Vietnamese male smokers and associated demographic and consumption factors.

METHODS

We analyzed a secondary dataset of male current tobacco smokers (n=3983) who participated in the Vietnam Global Adult Tobacco Survey in 2015. We applied the latent class analysis (LCA) to identify the classes of purchase behavior among cigarette smokers (n=1241). Multinomial logistic regression was performed to identify demographics (education level, ethnicity, partnership status, and household socioeconomic status) and cigarette consumption variables (smoking years and heavy smoking status) related to purchase behavior classes. The results are reported as an adjusted relative risk ratio (ARRR).

RESULTS

The LCA identified four cigarette purchase behaviors classes: Class 1 (price-insensitive and purchased international brand: 44.4%), Class 2 (price-sensitive and purchased domestic brand: 27.6%), Class 3 (price-sensitive and purchased cigarettes in a street vendor: 18.6%), and Class 4: price-sensitive and purchased loose/carton cigarette: 9.4%). The poorer economic groups were more likely to belong to the three price-sensitive classes. Heavy smokers and those who had smoked for a longer period were more likely to belong to Class 3 (ARRR=2.33; 95% CI: 1.51-3.58 and ARRR=1.02; 95% CI: 1.001-1.05, respectively) and Class 4 (ARRR=2.94; 95% CI: 1.71-5.06 and ARRR=1.05; 95% CI: 1.02-1.08, respectively).

CONCLUSIONS

Varied purchasing behaviors among male cigarette smokers, influenced by divergent price sensitivities and economic backgrounds, underscore the need for comprehensive tobacco control. Future efforts should include targeted policy interventions, behavior modification, and reshaping social norms.

Socioecological factors associated with multiple nicotine product use among U.S. youth: Findings from the population assessment of tobacco and health (PATH) study 2013-2018

OBJECTIVE

This study utilized a socioecological approach to prospectively identify intrapersonal, familial, and environmental factors associated with single nicotine product use (NPU) and multiple NPU among U.S. youth.

METHODS

Participants were 10,029 youths (ages 12-17 years) who had completed the Population Assessment of Tobacco Health study's Wave 1 (2013-2014) and Wave 4 (2016-2018) assessments and data on past 30-day nicotine product use. Multinomial logistic regression was fit for the 3-level outcome (no use, single NPU, multiple NPU) to estimate adjusted associations between the predictors and the outcome.

RESULTS

The current study found that intrapersonal (sex, age, race/ethnicity, internalizing symptoms, sensation seeking, harm perceptions, lifetime history of using two or more tobacco products), familial (parental discussion about not using tobacco and living with someone who uses tobacco products) and environmental factors (exposure to tobacco advertising) commonly associated with tobacco use differentiated between individuals who later reported past 30-day NPU (either multiple or single NPU) from those who did not report past 30-day NPU. One familial factor only differentiated between lifetime users who were single NPUs from those who reported no NPU: non-combustible tobacco product use allowed anywhere in the home. Intrapersonal factors differentiated multiple NPU from single NPU: older age, being male, lifetime history of using nicotine product and less harm perceptions.

CONCLUSIONS

This study identified factors that may be studied to prevent any NPU, along with factors that may be studied to promote harm reduction by preventing escalation of single NPU to problematic patterns of multiple NPU.

Come for the Tobacco, Stay for the Flavor: Flavored Cigarillo-Use Trajectories Among Young Adult Sexual Gender Minority Women

INTRODUCTION

The purpose of this research was to identify how young adult sexual gender minority (SGM) women who use cigarillos may respond to cigar flavor restrictions.

AIMS AND METHODS

Young adults aged 21-28 years in the United States who currently use cigarillos were recruited between October 2020 and April 2021 to participate in an online survey. Due to high prevalence of cigarillo use among individuals who identify as sexual and/or gender minority (SGM) women, their (n = 192) flavored tobacco-use behaviors and anticipated responses to cigarillo flavor restrictions were compared to cisgender heterosexual (CisHet) women (n = 110). Logistic regression was used to model cigarillo cessation and product-switching behaviors (flavored and unflavored).

RESULTS

SGM women were significantly less likely to report the use of flavor at the initiation of cigarillo use (61.7% vs. 86.1%) but were no different in current flavor use compared to CisHet women, with more than 80% of all women using any flavor. SGM women were 2.36 times as likely to say they would discontinue using cigarillos if flavors were unavailable. Among those who would continue using cigarillos, SGM women were 4.53 times as likely to endorse switching to an unflavored tobacco product but had the same likelihood of saying they would switch to flavored product compared to CisHet women.

CONCLUSIONS

Flavor restriction policies may not reduce the initiation of cigarillos among SGM women and may elicit differential cigarillo use and tobacco product substitution by SGM identity. Flavor restriction policies should be coupled with targeted cessation resources to address potential remaining disparities.

IMPLICATIONS

SGM US women have a unique cigarillo-use trajectory. These women are more likely to initiate cigarillos without flavor and then later integrate it into their behavior. National cigar flavor restrictions are expected to have a greater impact decreasing cigarillo initiation among CisHet women and decreasing current cigarillo use among SGM women. However, for those who would continue using unflavored cigarillos, SGM women may remain at risk for nicotine dependence due to increased product substitution. SGM women should be prioritized for cessation resources to reduce tobacco-use disparities leading up to and following the implementation of cigar flavor restrictions.

Differences in health care provider screening for tobacco use among youth in the United States: The National Youth Tobacco Survey, 2021

OBJECTIVE

Health care providers (HCP) are encouraged to screen youth for tobacco product use as a key step in preventing such use and associated health outcomes. However, recent data examining differences in HCP tobacco screening by sociodemographic characteristics and tobacco use is scant.

METHODS

Data from the 2021 National Youth Tobacco Survey (N = 14,685) were analyzed. Three types of HCP screening were examined: no screening, any e-cigarette use (e-cigarette only, e-cigarette and other tobacco), and non-e-cigarette tobacco product use. Differences by HCP screening were examined using multinomial logistic regression adjusted for age, sex, gender identity, sexual orientation, race/ethnicity, and tobacco use (non-current, sole, dual/poly).

RESULTS

Among the sample, 42.8% were screened for any tobacco use, with 30.6% screened for any e-cigarette use and 12.2% for non-e-cigarette tobacco product use only. Youth who were older (vs. younger) (OR = 5.98, 95% CI: 4.78-7.49) and gay/lesbian (vs. heterosexual) (OR = 1.47, 95% CI: 1.02-2.12) were more likely to be screened for e-cigarette use. Youth who were non-Hispanic Black (vs. non-Hispanic White) were less likely to be screened for e-cigarette use (OR = 0.53, 95% CI: 0.42-0.67) and more likely to be screened for non-e-cigarette tobacco use (OR = 1.34, 95% CI: 1.10-1.63). Current sole tobacco use (vs. non-current use) and dual/poly tobacco use (vs. non-current use) increased the likelihood for HCP screening for e-cigarette use.

CONCLUSIONS

The majority of U.S. youth continue to not be screened for tobacco use by their HCP. Evidence of disparities in tobacco use screening suggest the need for policies and training that promote equity in screening.

Flavour loyalty may predict cessation or substitution following a cigarillo flavour ban among young adults in the USA

SIGNIFICANCE

The purpose of this research was to measure flavour loyalty and identify how current cigarillo users may respond to a hypothetical flavour ban in the USA.

METHODS

Cigarillo users aged 21-28 (n=531) were recruited between October 2020 and April 2021 to participate in an online survey. Respondents categorised their preferred, usual and current cigarillo flavours. Individuals who preferred tobacco flavours were compared with individuals who preferred any other flavours. Strength of preferences, or flavour loyalty, was defined when an individual's preferred flavour matched what they use both usually and currently creating a spectrum of individuals with a strong tobacco preference (n=34), weak tobacco preference (n=20), weak flavour preference (n=162) and strong flavour preference (n=315). Those preferring tobacco were aggregated into any tobacco preference (n=54).

RESULTS

Individuals who preferred any flavour scored higher on a scale of nicotine dependence. There was a dose-response relationship in those who said they would discontinue cigarillos if flavoured options were not available: 11.4% of individuals with any tobacco flavour preference, 27.8% of those with a weak flavour preference and 38.1% of those with a strong flavour preference. A similar trend was noted among those who would switch to another product: 19.2% of those with tobacco flavour preference, 34.3% of those with a weak flavour preference and 43.2% of those with a strong flavour preference.

CONCLUSION

Individuals who display strong flavour preferences were more likely to say they would discontinue use or seek out alternative flavoured products following a ban on flavoured cigarillos.

Substitution of flavored cigarillos with menthol cigarettes among young adults in the U.S

BACKGROUND

Young adult cigarillo users often cite flavor as a primary reason for initiating and sustaining product use and are more likely to concurrently use other tobacco products such as menthol cigarettes. This study examines substitution with menthol cigarettes among cigarillo users facing a hypothetical ban on flavored cigarillos.

METHODS

Current young adult (21-28 years) cigarillo users were recruited from October 2020 to April 2021 for an online survey about cigarillo and other tobacco use behaviors. Participants (n = 500) self-reported past or current menthol cigarette experience, and if they would switch to menthol cigarettes if they could not get flavored cigarillos. Logistic regression was used to test differences in switching behaviors by level of experience with menthol cigarettes.

RESULTS

Most young adult cigarillo users (76.8 %) had ever used a menthol cigarette and 46.6 % reported current use of menthol cigarettes. No participant who had never used menthol cigarettes reported they would switch to menthol cigarettes. Current users were 4.2 times as likely to say they would switch after controlling for demographic characteristics and nicotine dependence.

CONCLUSION

Most young adult cigarillo users reported they would not switch to menthol cigarettes if flavored cigarillos became unavailable. However, participants who currently use or have used menthol cigarettes were more likely to report their intention to switch products than those who had never used menthol cigarettes. There may be a subsequent increase in menthol cigarette use among past menthol cigarette users if policies restricting flavored tobacco products exclude menthol cigarettes, diluting these policies' intended population health impact.

Changes in Little Cigar and Cigarillo Use during the COVID-19 Pandemic: A Cross-Sectional Analysis of a Nationally Representative Sample of Young Adult Users

We examined the smoking behaviors of U.S. young adults ages 18-36 regarding little cigars and cigarillos (LCCs) during the COVID-19 pandemic. Survey data were collected from a nationally representative sample of young adults between October and November 2020. Respondents who reported using LCCs with tobacco (CAI) and/or with marijuana (CAB) within the past 6 months prior to the survey (n = 399) were included in the study. Logistic regression analyses assessed the association between their perceived risk of having COVID when smoking LCCs and pandemic-related behavioral changes in CAI and CAB use (e.g., worrying, quit attempts, smoking more, smoking less). Findings showed that users with a higher perceived risk of getting COVID-19 when smoking LCCs were more likely to endorse trying to quit CAI and CAB during the pandemic. Compared to the non-Hispanic White population, the non-Hispanic Black population were less likely to endorse smoking less CAI and trying to quit CAB during the pandemic. Dual users of CAI and CAB and females were more likely to endorse smoking more CAB compared to CAB-only users and males, respectively. Tailored cessation strategies are needed for dual users, non-Hispanic Black young adults, and young women. Raising awareness about the risks of LCC use can be an effective strategy for LCC smoking cessation.

Dissonance in Young Adult Cigarillo Users' Categorization of Concept Flavored and Unflavored Products

This study asks young adult cigarillo users to categorize their preferred flavor in order to examine user consensus and potential methodological and regulatory implications of flavor name-based categorization systems. Young adult (21-28 years) cigarillo users (n = 426) named and categorized their favorite cigarillo flavor into one of seven categories: Fruit, Sweet and Candy, Mint, Alcohol, Menthol, Tobacco, and Other. Flavor responses were coded as characterizing (ex: Grape, Wine) or concept (ex: Jazz, Diamond) flavors. Variation within and between categories was assessed, including the presence of concept flavors and the placement of flavors in multiple categories. Of the 66 unique flavor names provided, participants placed 20 (30.1%) in more than one flavor category. Most of the Tobacco (76.9%) and Other (69.2%) flavor names appeared in multiple categories. The majority of flavor names in the Tobacco (69.2%) and Other (61.5%) categories were concept flavors. Concept flavors were placed in multiple categories (45.0%) twice as often as characterizing flavors (23.9%). This study has identified dissonance among cigarillo users' flavor categorizations, particularly for concept flavored and unflavored products. Flavor names may obscure how and whether a product is flavored. Research on and regulation of flavored tobacco products should classify products by flavor additives rather than by name alone.

Measuring nicotine dependence among adolescent and young adult cigarillo users

INTRODUCTION

Current measures of nicotine dependence (ND) were developed and validated for cigarette smokers only, limiting their utility for other combustible tobacco users. This study evaluates the psychometric properties of a pool of new and adapted items to measure ND among cigarillo and multiple tobacco product users.

METHODS

Items were drawn from the PROMIS Nicotine Dependence Item Bank which were adapted to be product neutral and new items were developed from a qualitative study of 60 adolescent and young adult cigarillo smokers. A total of 42 ND items were included in a web-based survey. Eligible participants were 14 to 28 year olds who smoked a minimum of 2 cigarillos per week. Analyses included confirmatory factor analysis, item response theory analysis, analysis of differential item functioning (DIF) and reliability. Ordinary least square regression was used to test the association of ND score with deciles of nicotine consumption.

RESULTS

Among the 1089 participants, the median number of cigarillos smoked per week was 20; 54% of participants also smoked cigarettes. All PROMIS items and 8 of 10 new items met the IRT fit criteria. Two PROMIS items had non-ignorable DIF. The pool of 40 items had good score reliability for a range of 2 standard deviations. Twenty-, eight-, and four-item short forms showed similarly good measurement properties; each was positively associated with decile of nicotine consumption, p<.001; R 2 = 0.33.

CONCLUSIONS

This adapted bank of ND items is psychometrically sound and includes items that are product neutral, making it suitable for assessing ND among cigarillo and polytobacco users.

IMPLICATIONS

This study rigorously evaluates adapted items to measure ND among cigarillo and polytobacco users and reports the reliability initial evidence of validity of short form scores.

Cigar Use Progression Among New Cigar Initiators: A Two-Part Growth Curve Analysis Among a Youth and Young Adult Cohort

INTRODUCTION

Youth and young adults (YYAs) are at high risk of cigar use. This study's objective was to examine progression and sociodemographic differences in current cigar use and frequency among new cigar initiators.

AIMS AND METHODS

We conducted a two-part latent growth model among a nationally representative cohort of cigar initiators (aged 15-25) to examine 24-month trajectories of current cigar use and frequency (n = 1483). The cohort was recruited via address-based sampling with online data collection from 2014 to 2019 and surveyed approximately every 6 months.

RESULTS

The unconditional odds of current cigar use (ie, past 30-day use) within 6 months of initiation was 0.72 (95% confidence interval: 0.63, 0.82), corresponding to a probability of 42%. The odds of current use among recent cigar initiates declined 6 months after initiation and was followed by a stabilization in use over time. Among continued users, frequency (# days used in past 30 days) increased linearly over time but remained low (3.47 days/months at 24 months). Younger individuals, non-Hispanic African Americans, those with lower subjective financial status, and current users of cigarettes, other tobacco products and/or marijuana were at highest risk within 6 months of initiation. Males, younger users, and current cigarette smokers had the highest risk for cigar progression over time.

CONCLUSIONS

This study is the first to examine longitudinal cigar use patterns among YYA cigar initiators. Findings emphasize the need for research across the cigar use spectrum and the importance of interventions targeted by age, stage of use, cigarette, other tobacco, and marijuana use and key sociodemographics to interrupt use pathways.

IMPLICATIONS

This study is the first to examine progression of cigar use among YYAs who have newly initiated cigars. Results show a high probability of current cigar use within 6 months of initiation followed by a rapid decline and stabilization over time. Frequency increases among those who continue using cigars. Males, younger users, and current cigarette smokers had the highest risk for cigar progression over time. Findings emphasize the need for targeting interventions by age, stage of use, cigarette, other tobacco, and marijuana use and key sociodemographics to interrupt use pathways.

Positive Affect and Multiple-tobacco Product Use among Youth: A 3-year Longitudinal Study

Objectives: Multiple-tobacco product (MTP) use is common among adolescent tobacco users. Low positive affect is a risk factor for e-cigarette use and combustible tobacco smoking. In this study, we examine the longitudinal relationship between positive affect and MTP use in a diverse cohort of adolescents in Texas. Methods: We analyzed 6 waves of biennial data (fall 2014-spring 2017) from the Texas Adolescent Tobacco and Marketing Surveillance (TATAMS) system. Participants were 3868 sixth-, eighth-, and tenth-grade students in urban Texas, at enrollment. Multinomial logistic regression models examined the longitudinal relationship between positive affect and categories of MTP use, controlling for sex, race/ethnicity, past 30-day alcohol use, cohort, survey wave, and peer tobacco use. Results: The sample was comprised of 4.6% single-product users, 1.7% dual-users, and 0.7% poly-users. Each unit decrease in positive affect was associated with increased risk for single- (RRR: 1.29; 95% CI: 1.16-1.44), dual- (RRR: 1.35; 95% CI: 1.11-1.64), and poly- (RRR: 1.98; 95% CI: 1.54-2.54) use, relative to non-use. Similarly, each unit decrease in positive affect was also associated with increased risk for poly-tobacco use relative to single- (RRR: 1.53; 95% CI: 1.19-1.97) and dual- (RRR: 1.47; 95% CI: 1.11-1.95) use. Positive affect did not differentiate between single- and dual-use. Conclusion: We observed a gradient relationship between low positive affect and greater number of tobacco products used. Findings reinforce the association between poor mental health and tobacco use during adolescence. Prevention efforts may need to incorporate methods of addressing low positive affect.
