Nicotine Pouch Unit Sales in the US From 2016 to 2020-Reply
Marynak K , Emery S , King BA . JAMA 12/28/2021 326 (22) 2331 Dr Hrywna and colleagues highlight synthetic nicotine pouch products as an emerging area of concern with implications for public health policy and practice at the national, state, and local levels in the US. We agree and add that synthetic nicotine is not limited to nicotine pouches. e-Cigarette manufacturers are also marketing disposable e-cigarettes and e-liquids with synthetic nicotine in the US, using claims such as “our nicotine-based products are crafted from a patented manufacturing process, not from tobacco.”1 | | Introduction of synthetic, flavored nicotine products that fall outside of existing statutory definitions of tobacco products1 may undermine existing efforts to reduce youth tobacco product use and to support youth tobacco cessation. As noted in our Research Letter,2 nicotine pouch flavors and marketing mirror e-cigarette marketing themes and tactics known to attract nicotine-naive young people. | | Whether derived from tobacco plants or synthetically developed in a laboratory, nicotine is an addictive drug with known adverse health consequences. Nicotine harms fetal development, and use during adolescence can cause addiction and can harm parts of the brain that control attention, learning, memory, mood, and impulse control. Nicotine use may also increase adolescents’ risk of future addiction to other drugs.3 In 2021, based on survey data, more than 2 million US middle- and high-school students are current users of e-cigarettes; most youths who use tobacco products want to quit and have already tried quitting.4,5 | | Given these public health considerations, synthetic nicotine products warrant urgent attention from policy makers, clinicians, and researchers. Sufficient scientific evidence about nicotine’s harmful effects exists to caution young people and pregnant adults against use of synthetic nicotine and to justify inclusion of synthetic nicotine products in existing regulatory efforts.3 Public health practitioners and policy makers can clarify the scope of practice and policy to include all nicotine products not approved for therapeutic purposes, regardless of source. Researchers can study both the prevalence of and adverse events associated with synthetic nicotine use by young people, including poisonings. In addition, consumer risk perceptions can be examined, including the potential for consumers to confuse these products with approved cessation aids or regard them as safe for use in pregnancy. Clinicians can emphasize that nicotine use in any form is addictive and harmful during adolescence and fetal development and encourage use of evidence-based cessation treatments proven to help people quit.3,6 |
Tobacco product use among high school students - Youth Risk Behavior Survey, United States, 2019
Creamer MR , Everett Jones S , Gentzke AS , Jamal A , King BA . MMWR Suppl 2020 69 (1) 56-63 Tobacco product use is the leading cause of preventable disease, disability, and death in the United States. This report used data from the 2019 Youth Risk Behavior Survey to assess the following among U.S. high school students: ever use of cigarettes and electronic vapor products, current use (≥1 day during the 30 days before the survey) of tobacco products, frequent use (≥20 days during the 30 days before the survey) among current users of tobacco products, trends in use over time, and usual source of electronic vapor products among current electronic vapor product users. In 2019, a total of 50.1% of U.S. high school students had ever used electronic vapor products, and 24.1% had ever tried cigarette smoking. Current electronic vapor product use was 32.7%, current cigarette smoking was 6.0%, current cigar smoking was 5.7%, and current smokeless tobacco use was 3.8%. Approximately 36.5% of students were current users of any tobacco product, and 8.2% were current users of two or more tobacco products. Frequent use among users of individual products was 32.6% for electronic vapor products, 28.5% for smokeless tobacco, 22.2% for cigarettes, and 18.4% for cigars. Among current electronic vapor product users who were aged ≤17 years, the most commonly reported source was borrowing them from someone else (42.8%). Significant decreases occurred in current cigarette smoking (1991: 27.5%; 2019: 6.0%), cigar smoking (1997: 22.0%; 2019: 5.7%), and smokeless tobacco use (2017: 5.5%; 2019: 3.8%). However, significant increases occurred in current electronic vapor product use (2015: 24.1%; 2019: 32.7%) and any tobacco product use (2017: 19.5%; 2019: 36.5%). Although current cigarette smoking, cigar smoking, and smokeless tobacco use has decreased among high school students, the increased prevalence of electronic vapor product use among youths is concerning. Continued surveillance for all tobacco product use is warranted for guiding and evaluating public health policy at the local, state, tribal, and national levels. |
Assessment of school staff knowledge and perceptions of student e-cigarette use and resource needs, and e-cigarettes confiscated at 12 North Carolina high schools-2019
Tanz LJ , Heck C , Herzig CTA , Ranney LM , Herndon S , Martin J , Hast M , McGowan E , Baler G , Shamout M , King BA , Tynan MA , Kansagra SM . NC Med J 2023 84 (6) 49-57 Background E-cigarettes are the most commonly used tobacco product among US youth and are regularly used on school grounds. We assessed school staff’s awareness of students’ e-cigarette use, response by schools, and resources needed to address use, and examined e-cigarettes confiscated by school staff in North Carolina to guide prevention and identify needed resources. methods In May 2019, staff from a random sample of 25 of 451 North Carolina public and charter high schools were invited to complete an online survey and semistructured interview; 12 schools consented to ≥ 1 component (survey, N = 514; interviews, N = 35). Staff knowledge and perceptions of students’ e-cigarette use and school tobacco policies were assessed, including school efforts to address e-cigarette use. E-cigarette products confiscated by nine schools from students during the 2018-2019 school year were collected. limitations Only 12 public high schools participated, and these schools might not be representative of all North Carolina high schools. Quantitative surveys were not collected from all staff at participating schools; however, the response rate was 62% and included different staff positions and both urban and rural schools. Finally, e-cigarette products collected by schools might not be representative of all devices used by students. Results Among surveyed staff, 33% observed students using e-cigarettes on school grounds; 86% believed e-cigarette use somewhat or largely contributes to learning disruptions. Overall, 94% of respondents knew their school’s policy prohibits student e-cigarette use on school grounds, and 57% were not confident their school has resources to help students quit. From 35 interviews, themes included concern that schools’ tobacco-free policies do not deter use and additional resources are needed to address e-cigarette use in schools. Of 336 collected devices, there were different e-cigarette types and most (65%) e-liquid bottles were flavored. conclusion Efforts are warranted to incorporate evidence-based curricula; educate staff, parents, and youth regarding health risks of ecigarette use; and help youth quit e-cigarettes. © 2023 by the North Carolina Institute of Medicine and The Duke Endowment.

Pulmonary Illness Related to E-Cigarette Use. Reply
Layden JE , King BA , Meiman J . N Engl J Med 2020 382 (4) 386 Diaz et al. highlight the potential for severe airway reactivity and perioperative challenges when performing bronchoscopy and BAL in patients with EVALI, and Russell and Cevik stress the importance of ruling out infectious causes in these patients. These two points reflect the complexities of evaluating patients with EVALI and managing their care. Recent Centers for Disease Control and Prevention clinical guidance emphasizes that the decision to perform a bronchoscopy and BAL should be made on a case-by-case basis and in consultation with pulmonary specialists.1 Many patients with EVALI have required intubation and mechanical ventilation, and consultation with critical care specialists is also recommended. |
Water Pipe (Hookah) Smoking and Cardiovascular Disease Risk: A Scientific Statement From the American Heart Association
Bhatnagar A , Maziak W , Eissenberg T , Ward KD , Thurston G , King BA , Sutfin EL , Cobb CO , Griffiths M , Goldstein LB , Rezk-Hanna M . Circulation 2019 139 (19) e917-e936 Tobacco smoking with a water pipe or hookah is increasing globally. There are millions of water pipe tobacco smokers worldwide, and in the United States, water pipe use is more common among youth and young adults than among adults. The spread of water pipe tobacco smoking has been abetted by the marketing of flavored tobacco, a social media environment that promotes water pipe smoking, and misperceptions about the addictive potential and potential adverse health effects of this form of tobacco use. There is growing evidence that water pipe tobacco smoking affects heart rate, blood pressure regulation, baroreflex sensitivity, tissue oxygenation, and vascular function over the short term. Long-term water pipe use is associated with increased risk of coronary artery disease. Several harmful or potentially harmful substances present in cigarette smoke are also present in water pipe smoke, often at levels exceeding those found in cigarette smoke. Water pipe tobacco smokers have a higher risk of initiation of cigarette smoking than never smokers. Future studies that focus on the long-term adverse health effects of intermittent water pipe tobacco use are critical to strengthen the evidence base and to inform the regulation of water pipe products and use. The objectives of this statement are to describe the design and operation of water pipes and their use patterns, to identify harmful and potentially harmful constituents in water pipe smoke, to document the cardiovascular risks of water pipe use, to review current approaches to water pipe smoking cessation, and to offer guidance to healthcare providers for the identification and treatment of individuals who smoke tobacco using water pipes. |
Evaluation of statewide restrictions on e-cigarette nicotine strength- United States, 2017-2022
Ali FRM , Schillo B , Crane E , Seaman EL , King BA . Addiction 2023 118 (9) 1701-1709 AIMS: To evaluate statewide policies restricting e-cigarette nicotine strength. DESIGN: A difference-in-difference regression analysis was used to compare e-cigarette sales in states that restrict nicotine strength with states with no restrictions. Since flavor restrictions might affect sales and nicotine strength, states with flavor restrictions were also assessed. SETTING AND CASES: United States e-cigarette retail sales data during January 2017-March 2022 were licensed from Information Resources Incorporated. States with restrictions included Massachusetts (restricted maximum nicotine strength to 3.5% and non-tobacco flavored e-cigarette sales in December 2019); Utah (restricted nicotine strength to 3.6% in September 2021); and Rhode Island, New York, and Washington (restricted non-tobacco flavor sales in October 2019, May 2020, and October 2019-January 2020 respectively). These were compared with data from 34 states with no e-cigarette nicotine strength or flavor restrictions MEASUREMENTS: Weighted mean nicotine strength and total unit sales. Total unit sales per 1,000 state population were summed into 4-week periods by state. Models controlled for emergency responses, state demographics, tobacco control policies, time, and state fixed effects. FINDINGS: Restricting both nicotine strength and flavors in Massachusetts was associated with a 2.04 percentage point (pp) reduction in mean nicotine strength and 86.76-unit reduction in monthly unit sales per 1,000 persons compared with states with no restrictions (all p<0.01). Restricting nicotine strength only in Utah was associated with a 1.77 pp (p<0.01) reduction in mean nicotine strength; however, there was no impact on unit sales. Restricting non-tobacco flavor sales only in Rhode Island, New York, and Washington slightly reduced mean nicotine strength (0.21, 0.62, and 0.19 pp, respectively) and sales (36.66, 34.51, and 16.37 units, respectively) (all p<0.01). CONCLUSIONS: US statewide policies restricting e-cigarette nicotine strength appear to be associated with reductions in average nicotine strength in sales within that state; however, there appears to be no impact on unit sales. When these policies are implemented along with flavor restrictions; reductions in average nicotine strength occur in addition to reduced unit sales. |
Trends in US e-cigarette sales and prices by nicotine strength, overall and by product and flavor type, 2017-2022
Ali FRM , Seaman EL , Crane E , Schillo B , King BA . Nicotine Tob Res 2022 25 (5) 1052-1056 INTRODUCTION: The e-cigarette market has expanded considerably in recent years, resulting in changes in availability and use of e-cigarettes with varying characteristics. AIMS AND METHODS: This study assessed trends in sales and prices of e-cigarettes by nicotine strength level, including by product type and flavor, during January 2017-March 2022. US e-cigarette retail sales data were licensed from IRI company. Nicotine strength was categorized as: <1%; 1% to <2%; 2% to <3%; 3% to <4%; 4% to <5%; ≥5%. E-cigarette flavors were categorized as tobacco, menthol, mint, or other flavors. Product type was categorized as prefilled cartridge devices, disposable devices, or e-liquid bottles. Trend analyses were performed using Joinpoint Regression. RESULTS: During January 2017-March 2022, the unit share of products containing ≥5% nicotine strength increased by 1486.3%, while the dollar share increased by 1345.5%. By March 2022, 80.9% of total unit sales were composed of products containing ≥5% nicotine strength. By flavor, the percentage of units sold with ≥5% nicotine strength was 61.3% of tobacco-flavor sales, 79.3% of menthol sales, 87.4% of mint sales, and 96.1% of other flavor sales. By product type, the percentage of units sold with ≥5% nicotine strength was 90.6% of disposable e-cigarette sales and 74.2% of prefilled cartridge sales. During January 2017-March 2022, the price of low-nicotine strength e-cigarettes increased, while the price of high-nicotine products either decreased or did not change. CONCLUSIONS: Sales of high nicotine-strength e-cigarettes have dominated the US e-cigarette market. Limiting the nicotine strength of e-cigarettes could be considered as part of a comprehensive tobacco control strategy to reduce youth access to and use of these products. IMPLICATIONS: The findings from this study indicate that previously reported increases in e-cigarette nicotine strength during 2013-2018 have continued through 2022. The US e-cigarette market sales continue to be dominated by relatively high-nicotine products. Strategies to address factors that make these products, particularly appealing to youth, including flavors and product innovations, are critical. Such strategies are important-as part of a comprehensive approach alongside other evidence-based population-level actions-to address youth e-cigarette use. Importantly, actions to reduce e-cigarette use among youth are not mutually exclusive from actions to maximize the potential benefits of e-cigarettes for increasing smoking cessation among adults. |

Meites E , Knuth M , Hall K , Dawson P , Wang TW , Wright M , Yu W , Senesie S , Stephenson E , Imachukwu C , Sayi T , Gurbaxani B , Svendsen ER , Khoury MJ , Ellis B , King BA . Public Health Rep 2022 138 (2) 333549221134130 ![]() OBJECTIVE: High-quality scientific evidence underpins public health decision making. The Centers for Disease Control and Prevention (CDC) agency provides scientific data, including during public health emergencies. To understand CDC's contributions to COVID-19 science, we conducted a bibliometric evaluation of publications authored by CDC scientists from January 20, 2020, through January 20, 2022, by using a quality improvement approach (SQUIRE 2.0). METHODS: We catalogued COVID-19 articles with 1 CDC-affiliated author published in a scientific journal and indexed in the World Health Organization's COVID-19 database. We identified priority topic areas from the agency's COVID-19 Public Health Science Agenda by using keyword scripts in EndNote and then assessed the impact of the published articles by using Scopus and Altmetric. RESULTS: During the first 2 years of the agency's pandemic response, CDC authors contributed to 1044 unique COVID-19 scientific publications in 208 journals. Publication topics included testing (n = 853, 82%); prevention strategies (n = 658, 63%); natural history, transmission, breakthrough infections, and reinfections (n = 587, 56%); vaccines (n = 567, 54%); health equity (n = 308, 30%); variants (n = 232, 22%); and post-COVID-19 conditions (n = 44, 4%). Publications were cited 40427 times and received 81921 news reports and 1058893 social media impressions. As the pandemic evolved, CDC adapted to address new scientific questions, including vaccine effectiveness, safety, and access; viral variants, including Delta and Omicron; and health equity. CONCLUSION: The agency's COVID-19 Public Health Science Agenda helped guide impactful scientific activities. CDC continues to evaluate COVID-19 priority topic areas and contribute to development of new scientific work. CDC is committed to monitoring emerging issues and addressing gaps in evidence needed to improve health. |
Impact of Massachusetts law prohibiting flavored tobacco products sales on cross-border cigarette sales.
Ali FRM , King BA , Seaman EL , Vallone D , Schillo B . PLoS One 2022 17 (9) e0274022 BACKGROUND: In June 2020, Massachusetts implemented a law prohibiting the sale of all flavored tobacco products, including menthol cigarettes. This law was associated with significant declines in overall cigarette and menthol cigarette sales in Massachusetts, however it is unknown whether the law has increased cross-border sales in neighboring states where menthol cigarettes are still sold. METHODS: U.S. cigarette retail scanner data were licensed from the IRi Company. Cigarette pack sales were summed in 4-week periods during January 2020-December 2021 (n = 832). Outcomes were state-level pack sales per 1000 population, overall and by flavor status (menthol and non-flavored). A difference-in-differences analysis was used to examine adjusted sales for Massachusetts border states (New Hampshire, Connecticut, Vermont, and Rhode Island) before (January 2020-May 2020) and after (June 2020-December 2021) the Massachusetts's law, compared to 28 non-border states. Control variables included state and time fixed effects; real price per pack; tobacco control policies; COVID-19 cases and deaths, and related statewide closure; and state sociodemographic characteristics. RESULTS: Following the law, unadjusted sales of menthol, non-flavored, and overall cigarettes trended upward in border states; however, these increases were not statistically significant or different from sales patterns in non-border states. This finding persisted after accounting for product prices, tobacco control policies, the COVID-19 pandemic, sociodemographic factors, and fixed effects. CONCLUSION: Laws prohibiting the sale of flavored tobacco products, including menthol products, reduce access to these products, while having no significant impact on cross-border sales in neighboring states where menthol cigarettes are sold. |
Trends in unit sales of cooling flavoured e-cigarettes, USA, 2017-2021
Ali FRM , Seaman EL , Diaz MC , Ajose J , King BA . Tob Control 2022 OBJECTIVE: Flavours that produce a cooling sensation, such as menthol, enhance the appeal of e-cigarettes among youth; but not all e-cigarettes that produce cooling sensations are labelled as menthol. This study assessed trends in unit sales of cooling flavoured e-cigarettes in the USA. DESIGN: E-cigarette retail sales during 26 January 2017 to 28 November 2021 were licensed from Information Resources, Inc, which records brick-and-mortar retail scanner sales but not online or vape shop sales. Cooling flavours were identified using six descriptors: menthol, ice, cool, chill, freeze or frost; ambiguous flavours were verified using online searches. Cooling flavours were categorised by characterising flavour (menthol, mint, other) and product type (prefilled cartridges, disposables, e-liquids). Joinpoint regression was used to assess sales and price trends. RESULTS: During January 2017 to November 2021, unit sales of cooling flavoured e-cigarettes increased by 693.0% (1.5 to 12.0 million units); the percentage of these sales from total sales increased from 26.4% to 54.9%. Among cooling flavours, percentage of menthol sales decreased from 94.5% to 73.0% (p<0.001). Among menthol cooling flavours, percentage of prefilled cartridges increased from 67.2% to 96.6% (p<0.001); among non-menthol cooling flavours, percentage of disposable e-cigarettes increased from 5.2% to 99.2% (p<0.001). There were no significant price differences between cooling and non-cooling flavoured disposable e-cigarettes. CONCLUSION: The percentage of cooling flavoured e-cigarette sales from total sales doubled during 2017-2021, and sales of non-menthol cooling disposable e-cigarettes experienced the highest percentage increase. Cooling flavoured e-cigarettes are important to consider when developing strategies to address flavoured e-cigarette use among youth. |
Flavors remain a major driver of youth e-cigarette use
King BA . Am J Public Health 2022 112 (7) e1-e2 Over the past decade, the landscape of youth e-cigarette use has been dynamic.1,2 E-cigarettes have been the most commonly used tobacco product among US youths since 2014,1 and in 2019, current (past-30-day) e-cigarette use prevalence reached a peak among middle-school (10.5%) and high-school (27.5%) students.3 During 2020 to 2021, the COVID-19 pandemic resulted in virtual learning for students, which impacted youth access to e-cigarettes, including from social sources; in 2020, before COVID-19 was declared a pandemic, more than half of youths who currently used e-cigarettes reported getting their e-cigarettes from a friend.3 Nonetheless, in 2021, more than 2 million US middle- and high-school students used e-cigarettes.2 |
Different Times Call for Different Measures: Using Retail Sales to Monitor the Tobacco Product Landscape.
Seaman EL , Ali FRM , Schillo BA , Vallone DM , King BA . Am J Prev Med 2022 63 (3) e99-e102 In the past 15 years, the tobacco product landscape has evolved rapidly. After the introduction of E-cigarettes in the 2000s and the growth and promotion of several brands, including JUUL, the use of these products rapidly increased among U.S. youth during 20112019.1, 2, 3 These increases were driven by multiple factors, including advertising themes that are similar to those previously found to promote youth cigarette smoking,4 flavors that appeal to youth,5 and the introduction of newer products with characteristics that appeal to young people (e.g., smaller and easily concealable or similar in size and shape to a USB flash drive). Newer E-cigarette types also deliver nicotine in the form of nicotine salts, which allows a particularly high level of nicotine to be inhaled more easily and with less irritation than the free-base nicotine that has traditionally been used in conventional tobacco products and older E-cigarette types.6 However, the diversification of the tobacco product landscape has not been limited to E-cigarettes, and other products also continue to reemerge or newly emerge. More recently, updated versions of heated tobacco products, which were originally introduced in the 1990s with limited consumer interest, have returned to the marketplace in several countries.7,8 Novel smokeless tobacco products,9 including nicotine pouches, have also recently emerged; these prefilled, microfiber pouches contain nicotine powder that dissolves in the mouth without requiring spitting. Given the quickly evolving tobacco product marketplace, it is critical that researchers rapidly collect data on these emerging products, particularly to document seminal increases in sales and use to inform timely public health interventions that can expeditiously mitigate the use among populations at increased risk, including young people. |
Evaluation of Statewide Restrictions on Flavored e-Cigarette Sales in the US From 2014 to 2020.
Ali FRM , Vallone D , Seaman EL , Cordova J , Diaz MC , Tynan MA , Trivers KF , King BA . JAMA Netw Open 2022 5 (2) e2147813 IMPORTANCE: e-Cigarettes are the most commonly used tobacco product among US youths. Flavors are among the most cited reasons for use of e-cigarettes among youths, and therefore, some states have imposed restrictions on flavored e-cigarette sales. To our knowledge, no study has compared e-cigarette sales between states with statewide flavored e-cigarette restrictions and states without such restrictions while controlling for co-occurring events. OBJECTIVE: To assess whether implementation of statewide restrictions on flavored e-cigarette sales in Massachusetts, New York, Rhode Island, and Washington was associated with a reduction in total e-cigarette unit sales from 2014 to 2020. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study with difference-in-differences analysis used e-cigarette retail sales data from Massachusetts, Rhode Island, and Washington, which implemented restrictions on flavored e-cigarette sales in October 2019; New York, which implemented these restrictions in May 2020; and 35 states without these restrictions (control states). Sales were summed into 4-week periods from August 24, 2014, to December 27, 2020, for a total of 2988 state-period observations. MAIN OUTCOMES AND MEASURES: A difference-in-differences analysis was conducted to compare e-cigarette unit sales in the 4 states with flavor restrictions (before and after implementation) with those in the 35 control states. The model controlled for other population-based policies and emergent events (eg, the COVID-19 pandemic). Data on 4-week e-cigarette unit sales were sorted into 4 flavor categories (tobacco, menthol, mint, and other). Unit sales were standardized to reflect the most common package sizes for each product type. RESULTS: Statewide restrictions on non-tobacco-flavored e-cigarette sales were associated with the following reductions in mean 4-week total e-cigarette sales in intervention states compared with control states from October 2019 to December 2020: 30.65% (95% CI, 24.08%-36.66%) in New York, 31.26% (95% CI, 11.94%-46.34%) in Rhode Island, and 25.01% (95% CI, 18.43%-31.05%) in Washington. In Massachusetts, the comprehensive sales prohibition of all e-cigarette products was associated with a 94.38% (95% CI, 93.37%-95.23%) reduction in 4-week sales compared with control states. Except in Massachusetts, where all sales of flavored e-cigarettes decreased, reductions were found only for non-tobacco-flavored e-cigarette sales in the other states with restrictions. Among control states, mean sales decreased by 28.4% from August 2019 to February 2020 but then increased by 49.9% from February through December 2020. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, statewide restrictions on the sale of flavored e-cigarettes in Massachusetts, New York, Rhode Island, and Washington were associated with a reduction in total e-cigarette sales. These findings suggest that not all e-cigarette users who purchased non-tobacco-flavored e-cigarettes switched to purchasing tobacco-flavored e-cigarettes after policy implementation. |
Individual and Collective Positive Health Behaviors and Academic Achievement Among U.S. High School Students, Youth Risk Behavior Survey 2017
Hawkins GT , Lee SH , Michael SL , Merlo CL , Lee SM , King BA , Rasberry CN , Underwood JM . Am J Health Promot 2021 36 (4) 8901171211064496 PURPOSE: We examined associations between academic grades and positive health behaviors, individually and collectively, among U.S. high school students. DESIGN: Cross-sectional study design. SETTING: Data were from the 2017 national Youth Risk Behavior Survey. Response rates were 75% for schools, 81% for students, and 60% overall (n = 14,765 students). SUBJECTS: Youth in grades 9th-12th. MEASURES: We focused on youth behaviors that can prevent or delay the onset of chronic health conditions. Seven dietary, 3 physical activity, 2 sedentary screen time, and 4 tobacco product use behaviors were assessed. Variables were dichotomized (0/1) to indicate that a score was given to the positive health behavior response (e.g.,, did not smoke cigarettes = 1). A composite score was created by summing each positive health behavior response among 16 total health behaviors. ANALYSIS: Multivariable logistic regression analyses for each individual health behavior, and a multivariable negative binomial regression for the composite score, were conducted with self-reported academic grades, controlling for sex, grade in school, race/ethnicity, and body mass index (BMI) categories. RESULTS: Controlling for covariates, students who reported mostly A's had 2.0 (P < .001) more positive health behaviors; students who reported mostly B's had 1.3 (P < .001) more positive health behaviors; and students who reported mostly C's had .78 (P < .001) more positive health behaviors, compared to students who reported mostly D's/F's. CONCLUSIONS: Higher academic grades are associated with more positive individual and cumulative health behaviors among high school students. Understanding these relationships can help inform efforts to create a healthy and supportive school environment and strive for health equity. |
Trends in Cigar Sales and Prices, by Product and Flavor Type - United States, 2016-2020
Wang X , Kim Y , Borowiecki M , Tynan MA , Emery S , King BA . Nicotine Tob Res 2021 24 (4) 606-611 INTRODUCTION: Cigar smoking has increased in recent decades as the cigar product landscape has diversified. This study assessed trends in U.S. cigar sales during 2016-2020. METHODS: Unit sales and average unit price for cigars were assessed during January 3, 2016-June 13, 2020, overall and by product and flavor type, for the 48 contiguous U.S. states and D.C. Assessed cigar types were large cigars, little cigars, and cigarillos; assessed flavor types were tobacco/unflavored, candy/sweets, fruit, menthol, alcohol, coffee, other flavors, and no flavor stated. A joinpoint regression model was used to assess the magnitude and significance of sales trends. RESULTS: During January 3, 2016-June 13, 2020, unit sales of cigarillos increased (average monthly percentage change (AMPC)=0.7%, p<0.001), while unit sales of large cigars (AMPC=-0.8%, p<0.001) and little cigars decreased (AMPC=-0.2%, p<0.001). The average price of cigarillos gradually decreased since mid-August 2017 (AMPC=-0.1%, p<0.001), and the average price of little cigars decreased from mid-June 2016 to mid-June 2019 (AMPC=-0.3%, p<0.001). In contrast, the average price of large cigars increased during the entire study period (AMPC=0.6%, p<0.001). Irrespective of cigar type, tobacco-flavored/unflavored products were the most commonly sold cigars during the assessed period; however, sales of other flavors varied by cigar type. CONCLUSIONS: Cigar sales and price vary by type over time in the U.S., including sales of cigarillos (94.2% of unit sales) increasing as their prices have decreased in recent years. Public health strategies are warranted to address the full scope of cigar types being used in the U.S. IMPLICATIONS: Surveillance of cigar sales data, including product characteristics, can provide a timely complement to self-reported survey data of cigar use. This study assessed trends in U.S. cigar sales during 2016-2020, including by product and flavor type. The findings indicate that sales of cigarillos, which comprise most cigar sales in the U.S. during the assessed period, increased as their prices decreased. Sales of certain flavors, such as candy/sweet cigarillos and coffee large cigars, increased significantly. These findings reinforce the importance of evidence-based strategies, including increasing price and restricting flavors, to reduce the affordability and consumption of cigars in the U.S. |
Combating the tobacco epidemic in North America: challenges and opportunities
King BA , Ahluwalia IB , Bacelar Gomes A , Fong GT . Tob Control 2021 31 (2) 169-172 According to the WHO, the Region of the Americas has the second lowest tobacco use prevalence of any WHO region.1 WHO projections based on trends since 2000 indicate that the Region of the Americas, which includes both North and South America, is the only region expected to achieve a 30% relative reduction in tobacco use by 2025.1 However, there are approximately 127 million persons who report smoking tobacco in the Americas Region,2 a majority of whom reside in North America.3 North America consists of 23 countries (see table 1) with a combined population of nearly 600 million people, or approximately 7.5% of the world’s population in 2019.4 Among North American countries, data from 2017 for persons aged 15 years or older show current tobacco smoking prevalence ranged from 6.0% in Panama to 27.8% in Cuba.5 Among students aged 13–15 years old in North American countries with available data through 2017, current tobacco smoking prevalence ranged from 4.4% in Dominican Republic to 18.1% in Mexico.5 Tobacco smoking among adults is higher among males than females across North America. However, the difference in prevalence between sexes in the Region of the Americas is among the lowest of any WHO region5; this pattern is particularly pronounced among youth, where tobacco smoking among girls is similar to or higher among boys in most countries.2 5 |
Trends in secondhand smoke exposure, 20112018: Impact and implications of expanding serum cotinine range
Tsai J , Homa DM , Neff LJ , Sosnoff CS , Wang L , Blount BC , Melstrom PC , King BA . Am J Prev Med 2021 61 (3) e109-e117 Introduction: The impact of defining secondhand smoke exposure among nonsmokers using an expanded serum cotinine range is currently unknown. Methods: This study assessed the trends in secondhand smoke exposure prevalence among a nationally representative sample of 23,753 U.S. nonsmokers aged ≥3 years. Serum cotinine ranges of 0.05–10 ng/mL (established) and of 0.015–10 ng/mL (expanded) were analyzed in 2021 using data from the 2011–2018 National Health and Nutrition Examination Survey. Results: During 2011–2018, the percentage of people with a serum cotinine range of 0.05–10 ng/mL remained stable (25.3% to 24.6%) across most sociodemographic subgroups but declined significantly among adult Mexican Americans aged ≥20 years (23.9% to 14.1%). However, the percentage of people with serum cotinine range of 0.015–10 ng/mL significantly declined (58.3% to 52.3%) among male individuals (60.9% to 55.0%), among female individuals (56.2% to 50.0%), among adults aged ≥20 years (55.8% to 49.2%), among Mexican Americans (60.9% to 41.2%), among people with a college degree or higher (44.4% to 36.0%), among those who rented their housing (71.7% to 62.5%), among people not living with someone who smoked inside the home (56.1% to 50.0%), and among Mexican Americans aged ≥20 years (60.9% to 39.1%) (all p<0.05 for linear trend test). Conclusions: Expanding the serum cotinine range to 0.015–10 ng/mL more than doubles the estimated proportion of U.S. nonsmokers exposed to secondhand smoke. In contrast to a serum cotinine range of 0.05–10 ng/mL, it suggests that progress has been made in reducing population-level secondhand smoke exposure during 2011–2018, especially among nonsmokers experiencing lower exposure levels. © 2021 |

Characteristics of e-Cigarette Use Behaviors Among US Youth, 2020
Wang TW , Gentzke AS , Neff LJ , Glidden EV , Jamal A , Park-Lee E , Ren C , Cullen KA , King BA , Hacker KA . JAMA Netw Open 2021 4 (6) e2111336 IMPORTANCE: Comprehensive surveillance of e-cigarette use behaviors among youth is important for informing strategies to address this public health epidemic. OBJECTIVE: To characterize e-cigarette use behaviors among US youth in 2020. DESIGN, SETTING, AND PARTICIPANTS: The 2020 National Youth Tobacco Survey, a nationally representative, cross-sectional, school-based survey of middle school (grades 6-8) and high school (grades 9-12) students, was conducted from January 16, 2020, to March 16, 2020. A total of 14 531 students from 180 schools participated in the 2020 survey, yielding a corresponding student-level participation rate of 87.4% and school-level participation rate of 49.9%. The overall response rate, a product of the school-level and student-level participation rates, was 43.6%. EXPOSURES: Current (past 30-day) e-cigarette use. MAIN OUTCOMES AND MEASURES: Self-reported current e-cigarette use behaviors (frequency of use, usual e-cigarette brand, and access source) by school level and flavored e-cigarette use and flavor types among current e-cigarette users by school level and device type. Prevalence estimates were weighted to account for the complex survey design. RESULTS: Overall, 14 531 students completed the survey, including 7330 female students and 7133 male students with self-reported grade level and sex. In 2020, 19.6% (95% CI, 17.2%-22.2%) of high school students and 4.7% (95% CI, 3.6%-6.0%) of middle school students reported current e-cigarette use. Among them, 38.9% (95% CI, 35.2%-42.6%) of high school users and 20.0% (95% CI, 16.0%-24.8%) of middle school users reported e-cigarette use on 20 to 30 days within the past 30 days. Among current users, JUUL was the most commonly reported usual brand (high school: 25.4%; 95% CI, 18.8%-33.4%; middle school: 35.1%; 95% CI, 27.9%-43.1%). Among current users, the most common source of obtaining e-cigarettes was from a friend (high school: 57.1%; 95% CI, 52.6%-61.4%; middle school: 58.9%; 95% CI, 51.4%-66.1%). Among current users, 84.7% (95% CI, 82.2%-86.9%) of high school students and 73.9% (95% CI, 66.9%-79.8%) of middle school students reported flavored e-cigarette use. Fruit-flavored e-cigarettes were the most commonly reported flavor among current exclusive e-cigarette users of prefilled pods or cartridges (67.3%; 95% CI, 60.9%-73.0%), disposable e-cigarettes (85.8%; 95% CI, 79.8%-90.3%), and tank-based devices (82.7%; 95% CI, 68.9%-91.1%), followed by mint-flavored e-cigarettes. CONCLUSIONS AND RELEVANCE: These results suggest that although current e-cigarette use decreased during 2019 to 2020, overall prevalence, frequent use, and flavored e-cigarette use remained high. Continued actions are warranted to prevent and reduce e-cigarette use among US youth. |
U.S. healthcare spending attributable to cigarette smoking in 2014
Xu X , Shrestha SS , Trivers KF , Neff L , Armour BS , King BA . Prev Med 2021 150 106529 INTRODUCTION: Cigarette smoking continues to be the leading cause of preventable disease and death in the U.S. Smoking also carries an economic burden, including smoking-attributable healthcare spending. This study assessed smoking-attributable fractions in healthcare spending between 2010 and 2014, overall and by insurance type (Medicaid, Medicare, private, out-of-pocket, other federal, other) and by medical service (inpatient, non-inpatient, prescriptions). METHODS: Data were obtained from the 2010-2014 Medical Expenditure Panel Survey linked to the 2008-2013 National Health Interview Survey. The final sample (n = 49,540) was restricted to non-pregnant adults aged 18 years or older. Estimates from two-part models (multivariable logistic regression and generalized linear models) and data from 2014 national health expenditures were combined to estimate the share of and total (in 2014 dollars) annual healthcare spending attributable to cigarette smoking among U.S. adults. All models controlled for socio-demographic characteristics, health-related behaviors, and attitudes. RESULTS: During 2010-2014, an estimated 11.7% (95% CI = 11.6%, 11.8%) of U.S. annual healthcare spending could be attributed to adult cigarette smoking, translating to annual healthcare spending of more than $225 billion dollars based on total personal healthcare expenditures reported in 2014. More than 50% of this smoking-attributable spending was funded by Medicare or Medicaid. For Medicaid, the estimated healthcare spending attributable fraction increased more than 30% between 2010 and 2014. CONCLUSIONS: Cigarette smoking exacts a substantial economic burden in the U.S. Continuing efforts to implement proven population-based interventions have been shown to reduce the health and economic burden of cigarette smoking nationally. |
Disparities in smokeless tobacco use in Bangladesh, India, and Pakistan: Findings from the Global Adult Tobacco Survey, 2014-2017
Zhao L , Mbulo L , Twentyman E , Palipudi K , King BA . PLoS One 2021 16 (4) e0250144 BACKGROUND: Smokeless tobacco (SLT) use is associated with multiple adverse health effects. It is prominent in Bangladesh, India, and Pakistan, but disparities in use within and across these countries are not well documented or understood. This study assessed the prevalence, patterns, and correlates of SLT use in these three countries. METHOD: Data came from the Global Adult Tobacco Survey, a household survey of adults aged ≥15 years. Data were collected in 2014 (Pakistan), 2017 (Bangladesh), and India (2016-2017). Current SLT use (nasal or oral use) was defined as reported SLT use daily or less than daily at the time of the survey. Prevalence of both overall and specific SLT types were assessed. Multivariate logistic regression was used to assess correlates of SLT use. RESULTS: Overall, SLT use among adults ≥15 years of age was 20.6% in Bangladesh, 21.4% in India, and 7.7% in Pakistan, corresponding to 22.0 million SLT users in Bangladesh, 199.4 million in India, and 9.6 million in Pakistan. Among current tobacco users overall, the percentage of those who used SLT was 58.4% (CI: 56.0-60.7) in Bangladesh, 74.7% (CI: 73.4-76.0) in India, and 40.3% (CI: 36.2-44.5) in Pakistan. The most commonly used oral SLT product was Zarda (14.5%) in Bangladesh, Khaini (11.2%) in India, and Naswar (5.1%) in Pakistan. Females had greater odds of SLT use than males in Bangladesh, but lower odds of SLT use than males in India and Pakistan. In all three countries, the odds of SLT use was higher among those 25 years and older, lower education, lower wealth index, and greater exposure to SLT marketing. CONCLUSION: An estimated 231 million adults aged 15 years or older currently use SLT in Bangladesh, India, and Pakistan, comprising 40.3%-74.7% of overall tobacco product use in these countries. Moreover, marked variations in SLT use exist by population groups. Furthermore, exposure to pro-SLT marketing was found to be associated with higher SLT use compared to non-exposed. It is important that tobacco control strategies address all forms of tobacco product use, including SLT. |

J Adolesc Health 2021 69 (2) 342-345 PURPOSE: To examine the chemical composition of JUUL pods collected from a convenience sample of 16 high schools in California to identify possible consumer modification or counterfeit use. METHODS: Using Gas Chromatography-Mass Spectrometry, we quantitatively analyzed the nicotine, propylene glycol (PG), and vegetable glycerin (VG) in JUUL pods (n = 26) collected from California high schools and compared results to commercial 3% (n = 15) and 5% (n = 24) JUUL pods purchased online. RESULTS: Most of the collected JUUL pods (24/26 pods) had a nicotine concentration (43.3 mg/ml, 95% PI: 21.5-65.1) outside the prediction intervals (PI) of the 3% (33.5 mg/ml, 95% PI: 31.8-35.2) and 5% (55.0 mg/ml, 95% PI: 51.5-58.3) commercial JUUL pods. Most (73%) collected JUUL pods had VG concentrations (583.5 mg/ml, PI: 428.9-738.1) lower than the 3% (722.2 mg/ml, PI: 643.0-801.4) and 5% (710.5 mg/ml, PI: 653.1-767.8) commercial JUUL pods. CONCLUSIONS: Used JUUL products collected from high school students or found on school grounds were not chemically consistent with the manufacturer's stated formulations. |
Disposable E-Cigarette Use among U.S. Youth - An Emerging Public Health Challenge
Wang TW , Gentzke AS , Neff LJ , Glidden EV , Jamal A , King BA , Hacker KA , Park-Lee E , Ren C , Cullen KA . N Engl J Med 2021 384 (16) 1573-1576 Previous increases in the use of electronic cigarettes (e-cigarettes) by youth were driven by multiple factors, including advertising, the use of appealing flavors, and the introduction of new devices with prefilled pods or cartridges and high nicotine levels, such as Juul.1 According to data from the National Youth Tobacco Survey (NYTS), 19.6% of high school students (3.02 million) and 4.7% of middle school students (550,000) reported current (within the preceding 30 days) e-cigarette use in 2020 — 1.8 million fewer than in 2019.2 However, e-cigarette use among youth remains prominent and the landscape of devices is evolving, both of which pose a public health challenge. We assessed the changes in device type–specific e-cigarette use during 2019 and 2020. |
Prevalence of Electronic Cigarette Use Among Adult Workers - United States, 2017-2018
Syamlal G , Clark KA , Blackley DJ , King BA . MMWR Morb Mortal Wkly Rep 2021 70 (9) 297-303 Electronic cigarettes (e-cigarettes) heat a liquid to produce an aerosol that usually contains nicotine, flavors, and other chemicals and that is inhaled by the user (1). E-cigarette aerosols generally have a lower number and level of harmful toxicants than conventional cigarettes; however, e-cigarette aerosols can contain harmful ingredients, including ultrafine particles, volatile organic compounds, and heavy metals (1,2). The U.S. Surgeon General has determined that evidence is inadequate to conclude that use of e-cigarettes, in general, increases smoking cessation (3). During 2014–2016, an estimated 5.2 million U.S. workers were current e-cigarette users, and prevalence of e-cigarette use was higher among workers in certain industries and occupations (4). To estimate recent national prevalence of e-cigarette use among U.S. workers, CDC analyzed 2017–2018 National Health Interview Survey (NHIS) data for adults aged ≥18 years who were employed during the week before the interview. Among an estimated 156 million U.S. workers, 5.3 million (3.4%) were current e-cigarette users (i.e., “every day” or “some days” use), approximately one half of whom also currently used combustible tobacco products. Current e-cigarette use was highest among males, non-Hispanic Whites, those aged 18–24 years, those with no health insurance, those reporting poor or fair physical health, and those who currently used other tobacco products. Prevalence of e-cigarette use was highest among workers in the accommodation and food services industry and in food preparation and serving-related occupations. Continued surveillance of e-cigarette use in the United States, including among workers, is important to inform the development and implementation of evidence-based strategies to minimize population risks of use of e-cigarettes while continuing to explore their potential usefulness for cessation among adult cigarette smokers (2,3). To maximize the health of workers, employers can integrate comprehensive and effective tobacco cessation programs into workplace health promotion programs (4,5). |
Receipt of and spending on cessation medication among US adults with employer-sponsored health insurance, 2010 and 2017
Shrestha SS , Xu X , Wang X , Babb SD , Armour BS , King BA , Trivers KF . Public Health Rep 2021 136 (6) 736-744 OBJECTIVE: Studies examining the use of smoking cessation treatment and related spending among enrollees with employer-sponsored health insurance are dated and limited in scope. We assessed changes in annual receipt of and spending on cessation medications approved by the US Food and Drug Administration (FDA) among tobacco users with employer-sponsored health insurance from 2010 to 2017. METHODS: We analyzed data on 439 865 adult tobacco users in 2010 and 344 567 adult tobacco users in 2017 from the IBM MarketScan Commercial Database. We used a negative binomial regression to estimate changes in receipt of cessation medication (number of fills and refills and days of supply). We used a generalized linear model to estimate spending (total, employers', and out of pocket). In both models, covariates included year, age, sex, residence, and type of health insurance plan. RESULTS: From 2010 to 2017, the percentage of adult tobacco users with employer-sponsored health insurance who received any cessation medication increased by 2.4%, from 15.7% to 16.1% (P < .001). Annual average number of fills and refills per user increased by 15.1%, from 2.5 to 2.9 (P < .001) and days of supply increased by 26.4%, from 81.9 to 103.5 (P < .001). The total annual average spending per user increased by 53.6%, from $286.40 to $440.00 (P < .001). Annual average out-of-pocket spending per user decreased by 70.9%, from $70.80 to $20.60 (P < .001). CONCLUSIONS: Use of smoking cessation medications is low among smokers covered by employer-sponsored health insurance. Opportunities exist to further increase the use of cessation medications by promoting the use of evidence-based cessation treatments and reducing barriers to coverage, including out-of-pocket costs. |
Tobacco smoking cessation and quitline use among adults aged 15 years in 31 countries: Findings from the Global Adult Tobacco Survey
Ahluwalia IB , Tripp AL , Dean AK , Mbulo L , Arrazola RA , Twentyman E , King BA . Am J Prev Med 2021 60 (3) S128-S135 Introduction: About 80% of the 1.1 billion people who smoke tobacco worldwide reside in low- and middle-income countries. Evidence-based approaches to promote cessation include brief advice from health professionals and referrals through quitlines. This study assesses cessation behaviors and the use of cessation services in the past 12 months among current tobacco smokers in 31 countries who attempted to quit. Methods: Data came from the Global Adult Tobacco Survey, a household-based survey of non-institutionalized adults aged ≥15 years. Surveys were conducted in 31 countries during 2008–2018; sample sizes ranged from 4,250 (Malaysia) to 74,037 (India), and response rates ranged from 64.4% (Ukraine) to 98.5% (Qatar). In 2019, data from the 31 countries were assessed in June 2019, and indicators included self-reported current (daily or less than daily) tobacco smoking, past-year quit attempts, and cessation methods used in the past 12 months. Results: Current tobacco smoking prevalence ranged from 3.7% (Ethiopia) to 38.2% (Greece). Overall, an estimated 176.8 million adults from the 31 countries made a quit attempt in the past 12 months, with country-level prevalence ranging from 16.4% (Greece) to 54.7% (Botswana). Most individuals who made a quit attempt did so without assistance (median=74.4%). Other methods were less prevalent, including quitlines (median=0.2%) and counseling (median=7.2%). Conclusions: In the assessed countries, the majority of those who currently smoked tobacco and made a quit attempt did so without assistance; very few reported using quitlines, partly because of the lack of quitlines in some countries. In resource-limited settings, quitlines can play a greater role in helping people quit smoking as part of a comprehensive approach. |
Frequency of cannabis use during pregnancy and adverse infant outcomes, by cigarette smoking status - 8 PRAMS states, 2017
Haight SC , King BA , Bombard JM , Coy KC , Ferré CD , Grant AM , Ko JY . Drug Alcohol Depend 2021 220 108507 BACKGROUND: Research on prenatal cannabis use and adverse infant outcomes is inconsistent, and findings vary by frequency of use or cigarette use. We assess (1) the prevalence of high frequency (≥once/week), low frequency (<once/week), and any cannabis use during pregnancy by maternal characteristics and adverse infant outcomes; (2) the prevalence of infant outcomes by cannabis use frequency, stratified by cigarette smoking; and (3) the association between cannabis use frequency and infant outcomes, stratified by cigarette smoking. METHODS: Cross-sectional data from 8 states' 2017 Pregnancy Risk Assessment Monitoring System (n = 5548) were analyzed. We calculated adjusted prevalence ratios (aPR) between cannabis use frequency and infant outcomes with Modified Poisson regression. RESULTS: Approximately 1.7 % and 2.6 % of women reported low and high frequency prenatal cannabis use, respectively. Prevalence of use was higher among women with small-for-gestational age (SGA) (10.2 %) and low birthweight (9.7 %) deliveries, and cigarette use during pregnancy (21.2 %). Among cigarette smokers (aPR: 1.8; 95 % CI: 1.1-3.0) and non-smokers (aPR: 2.1; 95 % CI: 1.1-3.9), high frequency cannabis use doubled the risk of low birthweight delivery but did not increase preterm or SGA risk. Regardless of cigarette use, low frequency cannabis use did not significantly increase infant outcome risk. CONCLUSIONS: Prenatal cannabis use was more common among women who smoked cigarettes during pregnancy. High frequency cannabis use was associated with low birthweight delivery, regardless of cigarette use. Healthcare providers can implement recommended substance use screening and provide evidence-based counseling and cessation services to help pregnant women avoid tobacco and cannabis use. |
Cost effectiveness of the Tips From Former Smokers Campaign - U.S., 2012-2018
Shrestha SS , Davis K , Mann N , Taylor N , Nonnemaker J , Murphy-Hoefer R , Trivers KF , King BA , Babb SD , Armour BS . Am J Prev Med 2021 60 (3) 406-410 INTRODUCTION: Since 2012, the Centers for Disease Control and Prevention has conducted the national Tips From Former Smokers public education campaign, which motivates smokers to quit by featuring people living with the real-life health consequences of smoking. Cost effectiveness, from the healthcare sector perspective, of the Tips From Former Smokers campaign was compared over 2012-2018 with that of no campaign. METHODS: A combination of survey data from a nationally representative sample of U.S. adults that includes cigarette smokers and literature-based lifetime relapse rates were used to calculate the cumulative number of Tips From Former Smokers campaign‒associated lifetime quits during 2012-2018. Then, lifetime health benefits (premature deaths averted, life years saved, and quality-adjusted life years gained) and healthcare sector cost savings associated with these quits were assessed. All the costs were adjusted for inflation in 2018 U.S. dollars. The Tips From Former Smokers campaign was conducted and the survey data were collected during 2012-2018. Analyses were conducted in 2019. RESULTS: During 2012-2018, the Tips From Former Smokers campaign was associated with an estimated 129,100 premature deaths avoided, 803,800 life years gained, 1.38 million quality-adjusted life years gained, and $7.3 billion in healthcare sector cost savings on the basis of an estimated 642,200 campaign-associated lifetime quits. The Tips From Former Smokers campaign was associated with cost savings per lifetime quit of $11,400, per life year gained of $9,100, per premature deaths avoided of $56,800, and per quality-adjusted life year gained of $5,300. CONCLUSIONS: Mass-reach health education campaigns, such as Tips From Former Smokers, can help smokers quit, improve health outcomes, and potentially reduce healthcare sector costs. |

Trends in manufacturer-reported nicotine yields in cigarettes sold in the United States, 2013-2016
Kuiper N , Coats EM , Crawford TN , Gammon DG , Loomis B , Watson CH , Melstrom PC , Lavinghouze R , Rogers T , King BA . Prev Chronic Dis 2020 17 E148 INTRODUCTION: A gradual reduction of cigarette nicotine content to nonaddictive levels has been proposed as an endgame strategy to accelerate declines in combustible tobacco smoking. We assessed manufacturer-reported nicotine yield in cigarettes sold in the United States from 2013 to 2016. METHODS: We merged machine-measured nicotine yield in cigarette smoke and pack characteristics obtained from reports filed by tobacco manufacturers with the Federal Trade Commission for 2013-2016 with monthly Nielsen data on US cigarette sales. Manufacturer-reported, sales-weighted, average annual nicotine yield was assessed, as were nicotine yield sales trends by quartile: markedly low (0.10-0.60 mg/stick), low (0.61-0.80 mg/stick), moderate (0.81-0.90 mg/stick), and high (0.91-3.00 mg/stick). Trends in overall, menthol, and nonmenthol pack sales, by nicotine yield quartiles over the study period and by year, were determined by using Joinpoint regression. RESULTS: During 2013-2016, average annual sales-weighted nicotine yield for all cigarettes increased from 0.903 mg/stick (95% CI, 0.882-0.925) in 2013 to 0.938 mg/stick (95% CI, 0.915-0.962) in 2016 (P < .05). For menthol cigarettes, yield increased from 0.943 mg/stick in 2013 (95% CI, 0.909-0.977) to 1.037 mg/stick in 2016 (95% CI, 0.993-1.081), increasing 0.2% each month (P < .05). Most pack sales occurred among high (41.5%) and low (30.7%) nicotine yield quartiles. Cigarette sales for the markedly low quartile decreased by an average of 0.4% each month during 2013-2016 (P < .05). CONCLUSION: During 2013-2016, manufacturer-reported, sales-weighted nicotine yield in cigarettes increased, most notably for menthol cigarettes. Continued monitoring of nicotine yield and content in cigarettes can inform tobacco control strategies. |
