Addict Behav 2024; 152:107982. [PMID: 38359494 PMCID: PMC10939726 DOI: 10.1016/j.addbeh.2024.107982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 02/05/2024] [Accepted: 02/09/2024] [Indexed: 02/17/2024]
Abstract
BACKGROUND Flavored 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. METHODS We 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. RESULTS Approximately 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). DISCUSSION Almost 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.

Abstract
BACKGROUND AND OBJECTIVES Disposable electronic cigarettes (e-cigarettes) are widely used by adolescents and young adults (AYAs). Whether using disposable devices is associated with future e-cigarette use patterns is unknown but important for informing e-cigarette regulation. METHODS Prospective longitudinal study combining data from adolescent (14-17 years) and young adult (21-24 years) cohorts from Southern California surveyed at baseline and approximately 8-month follow-up during 2021 to 2022. The analyses included AYAs who used e-cigarettes in the past 30 days at baseline and had exposure and outcome data (N = 403; adolescent n = 124, young adult n = 279). RESULTS In the pooled sample of AYAs who used e-cigarettes at baseline (57.2% cis-gender female, 56.2% Hispanic), 278 (69.0%) reported past 30-day disposable e-cigarette use, and 125 (31.0%) used only nondisposable e-cigarettes. Baseline use of disposable (versus only nondisposable) devices was associated with higher odds of continued e-cigarette use (adjusted odds ratio = 1.92; 95% confidence interval = 1.09-3.42) and a greater number of times used e-cigarettes per day at follow-up (adjusted incidence rate ratio = 1.29; 95% confidence interval = 1.02-1.63). In supplemental analyses, disposable e-cigarette use was associated with greater odds of no changes (versus reductions) in e-cigarette use frequency and puffs per episode from baseline to follow-up but was not associated with increases in use frequency and intensity. No differences in e-cigarette use outcomes were found between those with poly-device (disposable and nondisposable) versus only disposable device use. CONCLUSIONS Use of disposable e-cigarette devices among AYAs may be associated with higher risks for persistent e-cigarette use patterns, which should be considered in tobacco product regulation designed to protect AYAs.

Abstract
Tobacco harm reduction (THR) refers to strategies designed to reduce the health risks associated with tobacco smoking but may involve continued use of nicotine and/or tobacco. Next-generation products (NGPs) are a THR alternative as they do not burn tobacco or produce smoke and deliver nicotine and have fewer and substantially lower levels of harmful chemicals compared to cigarettes. Tobacco‑free nicotine pouches (TFNPs) are an emerging category of nicotine‑containing oral products that do not combust or contain tobacco leaf. Similar to Swedish snus, TFNPs are placed between a user's lip and gum, and nicotine is absorbed through the oral mucosa rather than being inhaled. The aim of this scoping review was to systematically collate and evaluate published scientific evidence (cut‑off of 31 May 2023) identified from bibliometric databases investigating the potential of TFNPs to contribute to THR. Overall, studies examining chemical constituents indicated that the use of TFNPs may result in lower exposure to toxicants than other tobacco or nicotine-containing products, both combustible and non‑combustible. This reduction in toxicant exposure has been demonstrated by multiple human biomarker studies and in vitro toxicological assessments to translate to harm reduction potential in smokers switching to TFNPs. However, further study is warranted. At present, there is some evidence from human behavioral research that TFNPs can support either transitioning away from smoking or reducing cigarette consumption. Furthermore, TFNP use appears very much limited to current users of traditional tobacco products, and youth uptake has been limited. In conclusion, the findings of this review indicate that TFNPs have the potential to support THR efforts and may help inform evidence‑based regulation.

Effects of flavour and modified risk claims on nicotine pouch perceptions and use intentions among young adults who use inhalable nicotine and tobacco products: a randomised controlled trial. Tob Control 2023:tc-2023-058382. [PMID: 38148143 PMCID: PMC11199376 DOI: 10.1136/tc-2023-058382] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 12/13/2023] [Indexed: 12/28/2023]
Abstract
BACKGROUND Availability of flavours and potential modified risk tobacco product (MRTP) claims may influence young adults' (YAs') perceptions of and intentions to use nicotine pouches ('pouches'). METHODS YAs aged 21-34 years (N=47, M age=24.5, SD=3.1) with past-month nicotine/tobacco use (10.6% cigarette-only, 51.1% e-cigarette-only, 38.3% dual use) and no intention to quit were randomised to self-administer four Zyn 3 mg nicotine pouches in a 4 (flavour; within-subjects: smooth, mint, menthol, citrus) × 2 (MRTP claim on packaging; between subjects: present or absent) mixed-factorial design. After self-administering each pouch, participants reported appeal, use intentions and perceived harm compared with cigarettes and e-cigarettes. Three mixed-factorial analysis of variances (ANOVAs) examined main and interactive effects of flavour and MRTP claim on appeal, use intentions and comparative harm perceptions. RESULTS Mint (M=55.9, SD=26.4), menthol (M=49.7, SD=26.8) and citrus (M=46.6, SD=24.8) flavours were significantly more appealing than smooth (M=37.6, SD=25.4; p<0.001). MRTP claim did not significantly affect product appeal (p=0.376). Use intentions were greater for mint (M=2.6, SD=1.3) and menthol (M=2.0, SD=1.1) flavours than smooth (M=1.8, SD=1.0; p=0.002). Flavour did not affect comparative harm perceptions (p values>0.418). MRTP claims increased use intention (p=0.032) and perceptions of pouches as less harmful than cigarettes (p=0.011), but did not affect perceived harm relative to e-cigarettes (p=0.142). Flavour × MRTP claim interactions were not significant. CONCLUSIONS Flavoured (vs smooth) pouches were more appealing to YAs. MRTP claims reduced perceived harm of pouches compared with cigarettes; however, intentions to switch were low. To protect YAs' health, regulatory restrictions could target flavours and MRTP claims.

Abstract
PURPOSE OF REVIEW The development and marketing of smokeless nicotine products in recent years have become increasingly popular among adolescents. In addition to well known conventional inhaled nicotine products, noninhaled products, such as nicotine toothpicks, orbs, lozenges, strips, and more, have dangerously captivated a new youth audience. Although smokeless nicotine products may seem to be less threatening than conventional inhaled nicotine products, there are significant risks associated with the use of these products, including addiction and severe health issues. The purpose of this review is to provide up-to-date information about alternative nicotine products currently on the market that may appeal to youth, and the dangers of nicotine use for pediatric populations. RECENT FINDINGS Smokeless nicotine products appeal to minors with their varying flavors and discrete packaging. These products may lead to nicotine toxicity as well as severe health problems, such as cancer, issues with reproduction, and heart attacks. Nicotine is extremely dangerous for young children; in fact, using nicotine products before the age of 18 years can lead to addiction and is linked to an increased likelihood of experimenting with stronger nicotine products or illicit drugs. The development of inconspicuous nicotine packaging has led to increasing concerns for accidental nicotine exposure and overdose in youth. SUMMARY Greater knowledge regarding current nicotine products on the market, specifically smokeless nicotine products, will help clinicians be more aware of the dangers associated with these products. Clinicians will be better able to provide their patients and families with proper guidance to avoid nicotine addiction, further drug use, and detrimental health issues. Caregivers and medical professionals must recognize novel and inconspicuous nicotine products commonly used among youth, understand the signs of nicotine abuse and dependence, and take measures to address possible nicotine-related health risks.

Abstract
PURPOSE OF REVIEW New nicotine and tobacco products such as electronic cigarettes and oral nicotine products have increased in use and threaten to addict a new generation of youth. This review summarizes current literature on nicotine and tobacco products used by youth, epidemiology, health effects, prevention and treatment of nicotine dependence, and current policies and regulations. RECENT FINDINGS Electronic cigarettes and oral nicotine products are popular among youth, attracting adolescents through exposure to deceptive marketing and fruit, candy and dessert flavors. Electronic cigarettes and oral nicotine product use can lead to nicotine addiction and is associated with respiratory, cardiovascular, and oral health problems, although long-term health effects are not fully known. The Food and Drug Administration (FDA) has authority to regulate nicotine and tobacco products; however, thousands of unregulated and unauthorized products remain on the market. SUMMARY Millions of adolescents continue to use nicotine and tobacco products, which puts them at risk for health problems, including nicotine addiction. Pediatric providers can provide prevention messages, screen youth for tobacco and nicotine use, and offer appropriate treatment options. Regulation of tobacco and nicotine products by the FDA is critical to reverse this public health epidemic of youth nicotine and tobacco use.

Abstract
IMPORTANCE Oral nicotine products such as pouches, lozenges, tablets, gums, and toothpicks are gaining popularity, especially among adolescents and young adults, with increased marketing. OBJECTIVE To estimate use patterns of oral nicotine products and likelihood of buying and liking products based on marketing, using a large group of adolescents, young adults, and adults. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional, online survey among U.S. participants (n = 6,131; ages 13-40 years) was conducted in November-December 2021. MAIN OUTCOMES AND MEASURES Ever, past-30-day, and past-7-day use, behaviors, and flavors of oral nicotine products. Liking marketing and likelihood of buying specific oral nicotine products (Zyn pouches and Lucy gum) from marketing. RESULTS Our sample included 2,025 (33.0%) ever-users, 1,191 (19.4%) past-30-day users, and 998 (16.3%) past-7-day users of any oral nicotine product. Use patterns by age (in years): ever-users (<21: 816 (22.3%); 21-40: 1,209 (48.9%)); past-30-day users (<21: 458 (12.5%); 21-40: 733 (29.7%)); and past-7-day users (<21: 383 (10.5%); 21-40: 615 (24.9%)). Across products, 10-18% of participants reported using nicotine strength ranging from 6-10 mg. Fruit, sweet/dessert, alcohol, coffee, and mint were the most used flavors. When shown marketing, ever-users liked and were likely to buy Zyn pouches compared to never users, and participants under 21 years felt equally targeted by Lucy and Zyn marketing. Liking Zyn marketing even a little bit compared to not at all increased the likelihood of buying Zyn pouches across age groups. After observing marketing, participants < 21 years were more likely to buy Zyn if they perceived marketing to contain messages about good tasting flavors (AOR 1.43, 1.09-1.87; 0.009) and helping to feel comfortable in social situations (AOR 1.38, 1.02-1.87; 0.033), and were more likely to buy Lucy if they felt it could be used anywhere (AOR 1.57, 1.05-2.33; 0.026). CONCLUSIONS This study provides a foundation for estimating use, behaviors, flavors, and marketing influence of oral nicotine products in the US and globally. Adolescent and young adult use of oral nicotine products and likelihood of buying products when exposed to marketing highlights the need for expanded tobacco use surveillance, marketing regulations, and counter marketing and educational efforts.

Abstract
Non-therapeutic, novel oral nicotine products are convenient, discreet to use, and flavored, with increasing sales in the United States. It is unclear whether these products appeal predominantly to adolescents already susceptible to inhalable nicotine products, or whether they attract adolescents who would not otherwise use nicotine. This study examined prevalence and correlates of susceptibility to inhalable and oral nicotine product use among adolescents. Ninth- and tenth-grade students from Southern California who had never used any nicotine product (N = 3129) completed an online survey in Fall 2021 assessing susceptibility to inhalable (i.e., cigarettes, e-cigarettes) and oral (e.g., pouches, gum, gummies) nicotine products. Multinomial logistic regression analyses estimated associations of demographic characteristics with odds of susceptibility to oral, inhalable, or both products. Susceptibility was highest for e-cigarettes (19.7%), followed by cigarettes (15.0%) and nicotine gum, lozenges, tablets and/or gummies (15.0%), and nicotine pouches (8.7%). Dual susceptibility to oral and inhalable products (vs. neither product type) was higher in cisgender female and non-cisgender (vs. cisgender male) adolescents (odds ratios [ORs] = 1.36-2.02; ps < 0.05). Hispanic adolescents (vs. Asian) were more susceptible to both products (OR = 1.47; p < .05). Lower-socioeconomic status (SES) and sexual minority adolescents were more susceptible to oral (ORs = 1.76-1.87; ps < 0.05) and both products (ORs = 1.32-1.88; ps < 0.05), compared to higher-SES and heterosexual adolescents. Adolescents in Southern California may be more susceptible to e-cigarettes than other nicotine/tobacco products. However, appreciable numbers may be susceptible to oral nicotine products, including some youth who might not otherwise use nicotine and youth from populations historically impacted by tobacco-related health disparities.

Abstract
Introducción. El consumo ocasional de nicotina puede generar una dependencia o adicción, siendo detectable mediante modificaciones en los mecanismos neurobiológicos. Objetivo. Contextualizar del consumo a la adicción e identificar teóricamente el mecanismo neurobiológico de transición del consumo regular del tabaco a la adicción de la nicotina. Metodología. Se realizó una búsqueda de artículos en inglés y español usando diferentes bases de datos y combinaciones de palabras clave, se seleccionaron los artículos que describieran las características de los procesos neurobiológicos implicados en el uso o consumo intermitentedel tabaco a la adicción a la nicotina como el tema principal. Resultados. El número de investigaciones relacionados a este tema es reducido, aún más en relación con la descripción de los procesos y cambios neurales de la adicción a la nicotina. La adicción a las drogas es un proceso neuroconductual complejo que altera los circuitos del sistema de motivaciónrecompensa del cerebro, por la disminución de la dopamina y la afectación en la regulación del glutamato en los ganglios basales y extensión de la amígdala se asocia con el craving, la anticipación y el déficit en la función ejecutiva. Conclusiones. El tabaco está considerado como una droga legal, por lo que su consumo pareciera ser inofensivo. Sin embargo, las evidencias muestran que su consumo a largo plazo tiene consecuencias graves en la salud de los individuos. El entender cómo cambia el hábito de fumar ocasionalmente al consumocrónico nos hace más conscientes sobre las adaptaciones en el cerebro.
