OBJECTIVE: The use of marijuana by middle and high school students could have important consequences, including physical harm, poor decision making, increased use of tobacco products, and involvement in the legal system. Determining the level of use by students provides the initial information needed to understand the extent of the problem and possible approaches to reducing student use. METHODS: The National Youth Tobacco Surveys provide important information about the frequency of use of nicotine and tobacco products by a representative sample of students in schools in the United States...

BACKGROUND: Despite the robust evidence of an excess risk of COVID-19 severity and mortality in ever smokers, the debate on the role of current and ex-smokers on COVID-19 progression remains open. Limited or no data are available on the link between electronic-cigarette (e-cigarette), heated tobacco product (HTP) and second-hand-smoke (SHS) exposure and COVID-19 progression. To fill this knowledge gap, we undertook the COvid19 and SMOking in ITaly (COSMO-IT) study. METHODS: A multi-centre longitudinal study was conducted in 2020-2021 in 24 Italian hospitals on a total of 1820 laboratory-confirmed COVID-19 patients...

BACKGROUND AND AIM: The addictive potential of electronic cigarettes (e-cigarettes) remains to be fully understood. We identified patterns and correlates of perceived addiction to e-cigarettes and perceived addictiveness of e-cigarettes relative to tobacco cigarettes (relative addictiveness) in dual-users as well as exclusive e-cigarette users. DESIGN: Observational study using cross-sectional survey data from England from the International Tobacco Control Project (ITC) Four Country Smoking and Vaping (4CV) survey...

BACKGROUND AND AIM: Electronic nicotine delivery systems (ENDS) can help people quit smoking combusted tobacco products (CTP), but most current and former smokers who use ENDS also intend to quit ENDS. This analysis measured whether ENDS cessation among current and former CTP smokers is associated with changes in CTP smoking or abstinence. DESIGN: Regression analysis of a nationally representative cohort from Waves 4 (W4) and 5 (W5) of the Population Assessment of Tobacco and Health Study (December 2016-November 2019)...

We aimed to examine how bidirectional relationships between mental health problems and tobacco use are formed over time by types of tobacco use in recent samples of U.S. youth. Data were drawn from Waves 1-4 of the Population Assessment of Tobacco and Health Study (N = 10,082) and analyzed using cross-lagged panel models. A high level of internalizing problems at Wave 1 predicted conventional cigarette smoking (adjusted odds ratio [AOR] = 1.19, 95% CI = 1.06-1.34) and e-cigarette use (AOR = 1...

OBJECTIVE: To evaluate the risk of low gestational weight gain (GWG) in women who use electronic cigarettes (e-cigarettes), combustible cigarettes, or both e-cigarettes and combustible cigarettes (dual use) during pregnancy. METHODS: We conducted a secondary analysis of the data from 176 882 singleton pregnancies in the 2016-2020 US Pregnancy Risk Assessment Monitoring System (PRAMS). Postpartum women self-reported their use of e-cigarettes and/or cigarettes during the last 3 months of pregnancy...

OBJECTIVE: To examine e-cigarette use by adults who smoke or have recently quit, and demographic characteristics associated with their use; to assess reasons for using e-cigarettes. DESIGN: The Cancer Institute NSW Tobacco Tracking Survey (CITTS) is an ongoing, serial, cross-sectional telephone survey study (40 interviews each week). This report is based on interviews during 4 January 2016 - 31 December 2020. SETTING, PARTICIPANTS: Randomly selected New South Wales adults who are current smokers (smoked cigarettes, pipes, or other tobacco products daily, weekly, or less often) or recent quitters (smoked tobacco products in the past twelve months but who no longer smoked)...

PURPOSE: This paper determines the association between youth e-cigarette use "to try to quit using other tobacco products, such as cigarettes" and having stopped smoking cigarettes (defined as an ever cigarette smoker who did not smoke in the past 30 days). METHODS: This study uses data from the NYTS from 2015 through 2021, focusing on youth who started smoking cigarettes before they started using e-cigarettes. Associations between using e-cigarettes to quit and having stopped smoking were computed using logistic regression accounting for the complex survey design and adjusting for level of nicotine dependence, year, age, gender, and race/ethnicity...

BACKGROUND: Electronic cigarette (EC) advertisements remain unregulated and approach consumers in TV commercials, print ads, radio, and other forms of digital marketing. This study aimed to assess whether exposure to EC advertisements is associated with the use of EC by using a meta-analysis of prospective studies. METHODS: We searched PubMed, EMBASE, and Web of Science in order to locate eligible studies in November 2021. Pooled adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were calculated using a random-effects meta-analysis...

Limited evidence exists on the association between electronic nicotine delivery systems (ENDS) and chronic respiratory disorders. This study examines the association of combustible tobacco and ENDS use with chronic respiratory disorders among US adults. Public-use data from the Population Assessment of Tobacco and Health (PATH) Study Wave 1 (2013-2014), Wave 2 (2014-2015), Wave 3 (2015-2016), and Wave 4 (2016-2018) were pooled. Analyses focused on adults with W1-W4 respiratory disorder data and current tobacco use at W4, as well as youth entering the adult cohort at W2 through W4 (N = 26,072)...

INTRODUCTION: Evidence indicates that physicians' smoking cessation advice is significant for tobacco control, which is an impetus to encourage smoking cessation among smokers, but the estimated influence of physicians' smoking cessation advice on smokers' intention to quit is limited in Shanghai, China. METHODS: We enrolled 1104 participants who were current smokers in the SJ (Songjiang) and FX (Fengxian) districts in Shanghai in 2021. An electronic questionnaire was used to collect data and SAS 9...

BACKGROUND: Dual use of combustible cigarettes and e-cigarettes is an emerging phenomenon among U.S. adults. Literature suggests two primary reasons for this emerging use (i.e., to help quit smoking and to stealth vape). This study investigated user profiles based on use intensity and the reasons for dual use. METHODS: A total of 1,151 U.S. adult dual users were drawn from the 2018-2019 Tobacco Use Supplement to the Current Population Survey. We divided them into four groups: daily dual users (n = 189), predominant smokers (n = 608), predominant vapers (n = 143), and non-daily dual users (n = 211)...

INTRODUCTION: Since 2016, California has implemented a series of policies, including prohibiting the sale of tobacco products and electronic cigarettes (e-cigarettes) to persons under 21, cigarette tax increase, and recreational marijuana legalization. The study aims to examine the use of cigarettes, e-cigarettes, and marijuana among young adults (ages 18-25) and their associations with other factors in the context of these policy changes. METHODS: We used the data from the California Health Interview Survey (CHIS) 2017-2018 to compare the rates of using cigarettes, e-cigarettes, and marijuana separately or any use of the three...

BACKGROUND: Electronic cigarette (e-cigarette) use has spread among adolescents in many countries, however users' characteristics are not well known. We aimed to compare characteristics of exclusive e-cigarette users to those of exclusive tobacco users and dual users. METHODS: Data come from a representative sample of 11-19 years old students in Paris, surveyed each year between 2013 and 2017. Current e-cigarette and tobacco use were ascertained in the preceding 30 days...

AIM: To (i) estimate the prevalence of adolescent vaping in 47 lower-middle, upper-middle and high-income countries, and (ii) test the association between implementation of World Health Organisation (WHO) tobacco control policies and adolescent e-cigarette use (also known as vaping) in 44 countries where implementation data were available. DESIGN: Cross-sectional surveys. SETTINGS: A total of 47 lower-middle, upper-middle and high-income countries...

BACKGROUND: Although combustible cigarette use is an established risk factor for severe COVID-19 disease, there is conflicting evidence for the association of electronic cigarette use with SARS-CoV-2 infection and COVID-19 disease severity. METHODS: Study participants were from the Kaiser Permanente Research Bank (KPRB), a biorepository that includes adult Kaiser Permanente members from across the United States. Starting in April 2020, electronic surveys were sent to KPRB members to assess the impact of the COVID-19 pandemic...

Importance: Physicians play a primary role in patient smoking cessation, yet their communication regarding e-cigarettes is not well understood. Objective: To assess physician-patient communication regarding e-cigarettes. Design, Setting, and Participants: A national cross-sectional survey in 2018 and 2019 was conducted. Participants were invited by mail; surveys were completed online. Respondents were 2058 board-certified physicians from family medicine, internal medicine, obstetrics and gynecology, cardiology, pulmonary, and oncology...

Tobacco use is a well-established risk factor for multiple adverse oral conditions. Few nationally representative oral health data sets encompass the current diversity of tobacco and nicotine products. This investigation examines the validity of oral health measures in the Population Assessment of Tobacco and Health (PATH) Study to assess relationships between tobacco use and oral health. Cross-sectional data from PATH Study wave 4 ( N = 33,643 US adults, collected 2016-2018) were used to obtain estimates for 6 self-reported oral conditions (e...

INTRODUCTION: In 2016, the Finnish Tobacco Act was revised to harmonise e-cigarette regulations with the EU Tobacco Products Directive. Unlike before, the sale of nicotine-containing e-liquids was allowed while additional national regulations included, for example, a ban for other than unflavoured and tobacco-flavoured e-liquids. This study examines the correlates of e-cigarette use before and after the comprehensive regulatory change, and characteristics and correlates of flavoured e-cigarette use after the flavour ban in the general Finnish population...

Rationale: Electronic cigarette (e-cigarette) use is highly prevalent among young adults. However, longitudinal data assessing the association between e-cigarette use and respiratory symptoms are lacking. Objectives: To determine whether e-cigarette use is associated with the development of respiratory symptoms in young adults. Methods: Data are derived from the PATH (Population Assessment of Tobacco and Health) study waves 2 (2014-2015), 3 (2015-2016), 4 (2016-2018), and 5 (2018-2019). Young adults aged 18-24 years at baseline with no prevalent respiratory disease or symptoms were included in the analyses...
