Youths' Perceptions of Nicotine Harm and Associations With Product Use

INTRODUCTION

Although nicotine is the main addictive substance in tobacco, tobacco combustion is responsible for most tobacco-related diseases. U.S. adults hold misperceptions about nicotine harm. However, little is known about youth nicotine perceptions.

AIMS AND METHODS

To address this gap, we assessed U.S. youths' nicotine perceptions and how these perceptions relate to tobacco use. Participants were youth (ages 12-17) in waves 4 (w4; December 2016-January 2018; N = 14 798) and 4.5 (w4.5; December 2017-December 2018; N = 12 918) of the Population Assessment of Tobacco and Health Study, a nationally representative longitudinal cohort study. We describe beliefs about nicotine; perceptions of the nicotine harm in cigarettes, e-cigarettes, and nicotine replacement therapy (NRT); and demographic differences. Regressions assess whether w4 nicotine perceptions predicted w4.5 tobacco use.

RESULTS

Most youth correctly responded that nicotine is the main cause of addiction (77.1%) but incorrectly responded that nicotine is the main substance that causes smoking-related cancer (74.7%). Youth distinguished between the harm of nicotine in different products, and on average rated the nicotine in cigarettes as most harmful, followed by e-cigarettes and NRT. Among youth who did not use at w4, greater harm perceptions of nicotine in cigarettes, e-cigarettes, and NRT were associated with lower likelihood of reporting current tobacco use at w4.5. Among youth who currently used cigarettes or e-cigarettes at wave 4, nicotine perceptions did not predict switching to e-cigarettes or cigarettes, respectively, at wave 4.5.

CONCLUSIONS

These findings underscore the challenge of developing effective and comprehensive communication strategies that accurately convey the effects of nicotine without encouraging tobacco use.

IMPLICATIONS

Many U.S. adults have misperceptions about nicotine, incorrectly believing it is the substance that causes most smoking-related cancers; studies have not assessed youth's perceptions of nicotine and how these perceptions relate to tobacco use. This study found that similar to adults, most youth incorrectly believed nicotine is the main substance that causes smoking-related cancer; youth also distinguish between the harmfulness of nicotine in different products, and rated the nicotine in cigarettes as most harmful, followed by e-cigarettes and NRT. Perceptions of the harm in different nicotine and tobacco products negatively predicted becoming a person who used tobacco a year later, but did not predict switching between e-cigarettes and cigarettes. Findings highlight the challenges of accurately communicating about the harms of nicotine without encouraging tobacco use; findings can be considered in the context of FDA's potential nicotine product standard that would lower nicotine levels in combustible tobacco products to a minimally or nonaddictive level.

U.S. public opinion toward policy restrictions to limit tobacco product placement and advertising at point-of-sale and on social media

The Family Smoking Prevention and Tobacco Control Act granted the U.S. Food and Drug Administration authority to regulate tobacco advertising and promotion, including at the retail level, and preserved state, tribal, and local tobacco advertising and promotion authorities. Public health experts have proposed prohibiting point-of-sale tobacco advertisements and product displays, among other tobacco advertising restrictions. We examined the prevalence and correlates of public support, opposition, and neutrality toward proposed tobacco product placement and advertising restrictions at point-of-sale and on social media utilizing the National Cancer Institute's 2020 Health Information National Trends Survey (HINTS) (N = 3865), a cross-sectional, probability-based postal survey of U.S. addresses conducted from Feb 24, 2020 to June 15, 2020 (Bethesda, MD). Frequencies and unadjusted, weighted proportions were calculated for support, neutrality, and opposition toward the three policies under study, and weighted, adjusted multivariable logistic regression was employed to examine predictors of neutrality and opposition. Tests of significance were conducted at the p < 0.05 level. Sixty-two percent of U.S. adults supported a policy prohibiting tobacco product advertising on social media; 55% supported a policy restricting the location of tobacco product advertising at point-of-sale; and nearly 50% supported a policy to keep tobacco products out of view at the checkout counter. Neutrality and opposition varied by sociodemographic characteristics including age, sex, education, rurality, and presence of children in the household. Understanding public opinion toward tobacco product placement and advertising restrictions may inform policy planning and implementation.

User experiences with a text messaging program for smoking cessation: A qualitative study (Preprint)

Background

Mobile health strategies for smoking cessation (eg, SMS text messaging–based interventions) have been shown to be effective in helping smokers quit. However, further research is needed to better understand user experiences with these platforms.

Objective

This qualitative study aims to explore the experiences of real-world users of a publicly available smoking cessation program (SmokefreeTXT).

Methods

Semistructured phone interviews were conducted with 36 SmokefreeTXT users between March and July 2014. Of these 36 participants, 50% (18/36) of participants completed the SmokefreeTXT program (ie, did not opt out of the program before the 6- to 8-week completion period), and 50% (18/36) did not complete the program (ie, requested to opt out of the program before the completion period). Interview questions focused on smoking behaviors, quitting history, opinions on the program’s content and structure, answering assessment questions, using keywords, reasons for opting out, and perceived usefulness of the program for quitting smoking. A thematic content analysis was conducted, with a focus on themes to increase program engagement and optimization.

Results

The findings highlighted features of the program that participants found beneficial, as well as some elements that showed opportunities for improvement to boost program retention and successful cessation. Specifically, most participants found the SmokefreeTXT program to be convenient and supportive of cessation; however, some found the messages to be repetitive and reported a desire for more flexibility based on their readiness to quit and cessation progress. We also found that program completion did not necessarily indicate successful smoking cessation and that program opt out, which might be interpreted as a less positive outcome, may occur because of successful cessation. Finally, several participants reported using SmokefreeTXT together with other evidence-based cessation methods or non–evidence-based strategies.

Conclusions

Qualitative interviews with real-world SmokefreeTXT users showed high program acceptability, engagement with program features, and perceived utility for smoking cessation. Our findings directly informed several program updates, such as adding an adaptive quit date feature and offering supplemental information on live support services for users who prefer human interaction during the cessation process. The study has implications for other digital tobacco cessation interventions and highlights important topics that warrant future research, such as the relationship between program engagement (eg, opt out and retention) and successful cessation.

The carrot and the stick? Strategies to improve compliance with college campus tobacco policies

OBJECTIVE

Tobacco-free policies are being rapidly adopted nationwide, yet compliance with these policies remains a challenge. This study explored college campus key informants' experiences with tobacco policies, and their perceived benefits, drawbacks, and outcomes.

PARTICIPANTS

The sample for this study was 68 key informants representing 16 different California universities with varying tobacco policies (no smoking indoors and within 20 feet of entrances, designated smoking areas, 100% smoke-free, and 100% tobacco-free).

METHODS

Qualitative, descriptive study. Semistructured interviews were transcribed verbatim and analyzed using content analysis.

RESULTS

Strategies to improve compliance ranged from a social approach to a heavy focus on punitive enforcement. Key informants from campuses using a social approach alone reported barriers to improving compliance, including a perceived lack of efficacy of the approach. However, these campuses found it challenging to incorporate enforcement through campus police or security.

CONCLUSIONS

College campus decision makers should explore using a combined approach (social approach as well as formal enforcement), with enforcement primarily the responsibility of nonpolice university channels (eg, Student Affairs, employee supervisors).

Adolescent (Mis)Perceptions About Nicotine Addiction: Results From a Mixed-Methods Study

PURPOSE

Despite evidence that adolescents become addicted to nicotine even after limited use, adolescents believe they can experiment with or smoke cigarettes for a few years and easily quit. The goal of this study was to examine adolescents' understanding of the definition and process of nicotine addiction using a mixed-methods approach.Method A total of 367 adolescents with and without smoking experience rated the perceived risk for addiction, still being a smoker in 5 years, and ability to quit smoking. A subsample of adolescents (N= 41) were interviewed about their conceptualization and understanding of nicotine addiction. Within-participants analyses of variance were conducted to assess differences in perceptions of addiction across the three scenarios; thematic analyses of interviews were conducted to assess adolescents' understanding of addiction.Results Adolescents rated their perceived risk for addiction, still being a smoker in 5 years, and ability to quit as significantly different from one another for three different scenarios (F= 7.81, 47.78, and 70.27, respectively;p< .001). Seven themes describing how youth conceptualize and understand addiction emerged from the interview data, including skepticism and uncertainty about addiction, how smoking makes a person feel, and family and friends' experiences.

CONCLUSION

While adolescents have received the message that cigarettes are addictive, they are uncertain regarding the definition of addiction and have not recognized that addiction means experiencing difficulty quitting and continuing to smoke longer than expected. Findings suggest the need for comprehensive messaging regarding nicotine addiction in educational, clinical, and intervention settings and for product warning messages aimed at reducing and preventing tobacco use.

Association of campus tobacco policies with secondhand smoke exposure, intention to smoke on campus, and attitudes about outdoor smoking restrictions

College campus tobacco-free policies are an emerging trend. Between September 2013 and May 2014, we surveyed 1309 college students at 8 public 4-year institutions across California with a range of policies (smoke-free indoors only, designated outdoor smoking areas, smoke-free, and tobacco-free). Stronger policies were associated with fewer students reporting exposure to secondhand smoke or seeing someone smoke on campus. On tobacco-free college campuses, fewer students smoked and reported intention to smoke on campus. Strong majorities of students supported outdoor smoking restrictions across all policy types. Comprehensive tobacco-free policies are effective in reducing exposure to smoking and intention to smoke on campus.
