Regional variations and market share of FDA-authorised products for top-selling electronic cigarette brands in the USA
The differences in top brands by region reflect challenges in the surveillance of e-cigarette sales, marketing and use and reflect the rapidly changing disposable e-cigarette marketplace, in which new brands are introduced and popularised at high frequency, as manufacturers of disposable e-cigarettes adapt to exploit regulatory loopholes. In the context of other emerging markets, like nicotine pouches, we urge regulators to act quickly to regulat…
A Qualitative Exploration of Quitline Perceptions among African American and Hispanic or Latino Adults Who Smoke
Introduction Tobacco quitlines are efficacious, accessible, and cost-effective. While the prevalence of cigarette smoking remains higher among non-Hispanic White adults, the quit ratio has remained lower for African American (AA) and Hispanic or Latino (H/L) adults who smoke. The National Jewish Health Quitline (NJH QL) has sought to address whether current QL services provide effective and equitable tobacco cessation services. This study evaluat…
A Comparison of Mental Health Symptoms among Adults Who Vape Nicotine, Cannabis, or Both
OBJECTIVES: Dual use of combustible cannabis and nicotine is related to worse mental health symptoms (MHS); however, little is known about MHS among those who vape cannabis and nicotine. The current study aimed to determine if dual use of cannabis and nicotine vapes is associated with worse MHS compared to single use and to identify correlates of MHS for dual users. METHODS: = 492) who used nicotine or cannabis vapes in the past 30 days on stress…
Likely Response to a Hypothetical Menthol Cigarette Ban Among Adults with Mood Disorders Who Smoke Menthol Cigarettes and Have No Current Plans to Quit Smoking
Among individuals with mood disorders and who smoke menthol cigarettes and have no plans to quit smoking, 22.1% may try to quit smoking if a menthol ban is implemented, while the majority (58.4%) stated that they would switch to non-menthol cigarettes. As the reasons for using menthol cigarettes included perceived lower harm, there is a need for targeted public awareness campaigns to correct misconceptions about the harms of menthol cigarettes
Effects of liquid nicotine concentration and flavour on the acceptability of electronic nicotine delivery systems (ENDS) among people who smoke participating in a randomised controlled trial to reduce…
Both nicotine concentration and flavour appear to have independent, as well as interactive, effects that influence ENDS acceptability among people who use cigarettes
Racial Differences in Nicotine Reduction
Introduction Tobacco regulatory policies are generally intended to apply to all segments of the population and to be equitable. Results from clinical trials on switching from commercial cigarettes to reduced nicotine cigarettes have included black populations but race-specific findings are not widely reported. Methods Data were pooled from two parallel randomized controlled trials of gradually reduced nicotine in cigarettes from 11.6 mg per cigar…
A Comparison of Vaping Behavior, Perceptions, and Dependence among Individuals Who Vape Nicotine, Cannabis, or Both
Background: Electronic delivery systems (e.g., vapes, e-cigarettes) are now popular modes of cannabis and nicotine administration that are often used by the same individuals; however, we still know little about dual nicotine and cannabis vaping. Materials & Methods: An online convenience sample of adult nicotine and/or cannabis vape users residing in the United States completed a 60 min survey on sociodemographic characteristics, cannabis and/or …
Feasibility of Patient Navigation-Based Smoking Cessation Program in Cancer Patients
Continued smoking after a cancer diagnosis is causally associated with increased risks of all-cause and cancer-specific mortality, and of smoking-related second primary cancers. Patient navigation provides individualized assistance to address barriers to smoking cessation treatment and represents a promising bridge to smoking cessation in persons with cancer who smoke cigarettes. We conducted a single-arm interventional cohort study of current sm…
Dependence and Use Characteristics of Adult Juul Electronic Cigarette Users
Background JUUL is a popular electronic cigarette (e-cig) that is capable of delivering nicotine similarly to a cigarette. While known to deliver high doses of nicotine, there is little systematic evidence to show how the nicotine delivery of JUUL translates to user dependence. Purpose: The purpose of the study was to evaluate self-reported dependence of JUUL users and examine the relationship of dependence to user behaviors. Methods: Current JUU…
Tobacco Use Changes and Perceived Health Risks among Current Tobacco Users during the Covid-19 Pandemic
COVID-19 has become a global pandemic, with over 81 million cases worldwide. To assess changes in tobacco use as a result of the pandemic, we surveyed a convenience sample of current tobacco users between April and June 2020. The sample was taken from a tobacco user research registry ( n = 3396) from the Penn State College of Medicine in Hershey, Pennsylvania, USA. Participants who responded to the survey and were eligible for this study ( n = 29…
Biochemical Verification of Tobacco Use and Abstinence
BACKGROUND: The changing prevalence and patterns of tobacco use, the advent of novel nicotine delivery devices, and the development of new biomarkers prompted an update of the 2002 Society for Research on Nicotine and Tobacco (SRNT) report on whether and how to apply biomarker verification for tobacco use and abstinence. METHODS: The SRNT Treatment Research Network convened a group of investigators with expertise in tobacco biomarkers to update t…
Acceptability of electronic nicotine delivery systems (ENDS) among HIV positive smokers
Electronic nicotine delivery systems (ENDS) have the potential to help smokers living with HIV/AIDS (PLWHA) to reduce harms from tobacco use. However, little is known about ENDS use among PLWHA. This study’s aim was to evaluate the acceptability of two types of ENDS among PLWHA not planning to quit smoking. The study utilized a cross-over design where participants used two ENDS in a random order as smoking substitutes during two use periods separ…
Comparison between Gradual Reduced Nicotine Content and Usual Nicotine Content Groups on Subjective Cigarette Ratings in a Randomized Double-Blind Trial
In 2018, the United States Food and Drug Administration (FDA) issued an advanced notice of proposed rulemaking to reduce nicotine in tobacco products to produce a minimally addictive or nonaddictive effect, but there was a research gap in the subjective responses of reduced-nicotine-content cigarettes. We compared the responses of the modified cigarette evaluation questionnaire (mCEQ) and cigarette-liking scale (CLS) between the gradually reduced…
What Low-income Smokers Have Learned from Public Health Pedagogy
Objectives: Health advocates have been working to educate the public about the harms of smoking for more than 50 years. However, smoking rates have reduced more slowly among people with low incomes. The purpose of this study was to evaluate what low-income smokers have learned from a lifetime of exposure to public health education and how this knowledge may have translated into smoking-related behaviors. Methods: We used narrative inquiry and eli…
Effect of Cigarette Rod Length on Smokers Switching to SPECTRUM Cigarettes
Objectives: Cigarettes vary in rod length but are generally thought of as a constant unit. In this study, we evaluated whether the rod length of participants' usual brand cigarettes affected their perceptions and smoking habits when switching to SPECTRUMs. Methods: Data were analyzed for 341 participants smoking their own brand cigarettes for one week and after switching to normal nicotine content (11.6 mg) SPECTRUMs for 2 weeks. Changes in perce…
Answering questions about electronic cigarettes using a multidisciplinary model
Electronic cigarettes (ECIGs) are a relatively new class of tobacco products and a subject of much debate for scientists and policymakers worldwide. Objective data that address the ECIG risk-benefit ratio for individual and public health are needed, and addressing this need requires a multidisciplinary approach that spans several areas of psychology as well as chemistry, toxicant inhalation, and physiology. This multidisciplinary approach would b…
E-cigarette users commonly stealth vape in places where e-cigarette use is prohibited
Stealth vaping is a common behaviour for many experienced e-cigarette users. More research is needed to understand the reasons for stealth vaping and its potential health and safety implications. This information could help researchers and regulators to design interventions to minimise the public health impact of stealth vaping

Should electronic cigarette use be covered by clean indoor air laws
This study found that most vapers report unrestricted use of their e-cig. Of the restricted vapers, the majority (88%) do not find it difficult to refrain from vaping in places where they are not supposed to vape
Development of a Questionnaire for Assessing Dependence on Electronic Cigarettes Among a Large Sample of Ex-Smoking E-cigarette Users
INTRODUCTION: Electronic cigarettes (e-cigs) are becoming increasingly popular, but little is known about their dependence potential. This study aimed to assess ratings of dependence on electronic cigarettes and retrospectively compare them with rated dependence on tobacco cigarettes among a large sample of ex-smokers who switched to e-cigs. METHODS: A total of 3,609 current users of e-cigs who were ex-cigarette smokers completed a 158-item onlin…
Views of experienced electronic cigarette users
Experienced e-cig users stated that initiating e-cig use helped them to quit or reduce their conventional smoking, which they believe reduced their health risks. In comparison to cigarette smoking, e-cig users reported using their e-cig more times per day, but with fewer puffs at each use time. Users acknowledged that more research is needed to understand the safety and long-term effects of use. They mentioned dry mouth as a common side effect an…
Estimating the Harms of Nicotine-Containing Products Using the MCDA Approach
Background: An international expert panel convened by the Independent Scientific Committee on Drugs developed a multi-criteria decision analysis model of the relative importance of different types of harm related to the use of nicotine-containing products. Method: The group defined 12 products and 14 harm criteria. Seven criteria represented harms to the user, and the other seven indicated harms to others. The group scored all the products on eac…
Causes of the Decline in Cigarette Smoking Among African American Youths From the 1970s to the 1990s
Adult cigarette smoking prevalence trends among African Americans (AAs) and Whites are similar. However, during the decline in youth smoking that occurred between the mid-1970s and the early 1990s, the drop in smoking rates among AA adolescents was more than double that among Whites. We examined the evidence for potential explanations for this phenomenon. On the basis of our findings, we propose that racial differences in parental attitudes, reli…
Trading Tobacco
The analysis of Ringel and colleagues,1 who found that youths’ cigar use is sensitive to price, highlights an important but overlooked issue in public health—the use of tobacco products other than cigarettes. However, since 1999 and 2000, when the data used by Ringel et al. were collected, there have been many changes that deserve discussion. Cigar consumption in the United States increased by more than 28% between 2000 and 2004, whereas cigarett…
