INTRODUCTION: Electronic cigarettes (also termed e-cigarette or vapes) often contain nicotine, an addictive psychoactive substance, which can have harmful effects during adolescence. Frequent experiences of discrimination are one risk factor shown to increase susceptibility to tobacco use, especially for individuals that identify as a social minority. Applying Intersectionality Theory, this research examined the relationship between youth experiences of discrimination and vape use at the intersection of race/ethnicity and sexual orientation...

INTRODUCTION: More young adults (age 18-24 years) in rural areas versus urban areas use electronic nicotine delivery systems (ENDS) - also known as e-cigarettes. Little is known about young adults' perceptions toward ENDS use and cessation. The objective of this study was to examine barriers and facilitators to ENDS use cessation among young adults living in rural areas, as well as their perceptions about ENDS use and cessation and to determine implications for future cessation studies...

BACKGROUND: Little is known about the influence of e-cigarette marketing features on the antecedents of e-cigarette use. PURPOSE: Using an eye-tracking experiment, we examined visual attention to common features in e-cigarette ads and its associations with positive e-cigarette perceptions among young adults. METHODS: Young adults (ages 18-29) who smoke cigarettes (n = 40) or do not use tobacco (n = 71) viewed 30 e-cigarette ads on a computer screen...

BACKGROUND: Recent reports indicated accelerated rates of e-cigarette use, especially among youth in various Middle Eastern countries, including Palestine. Nevertheless, little is known about knowledge, attitudes, and perceptions regarding this topic in Palestine. This study aimed to assess the prevalence of e-cigarette use among Palestinian university students, along with their knowledge, attitudes, and perceptions about e-cigarette use. METHODS: An observational cross-sectional study, utilizing an online self-administered questionnaire, was conducted on Palestinian students from five universities between 17/04/2023 and 04/11/2023...

BACKGROUND: During the use of electronic cigarettes (e-cigarettes), users are still exposed to carcinogens similar to those found in tobacco products. Since these carcinogens are metabolized and excreted in urine, they may have carcinogenic effects on the bladder urinary tract epithelium. This meta-analysis aimed to compare bladder cancer carcinogens in the urine of tobacco users and e-cigarette users using a large number of samples. METHODS: A systematic meta-analysis was performed using data obtained from several scientific databases (up to November 2023)...

UNLABELLED: The article is devoted to the analysis of the results of the global surveys among youth 13-15 years old on tobacco consumption, conducted in 2004, 2015, 2021 in Khabarovsk, Novosibirsk, Cheboksary, Moscow, Pskov and the Russian Federation. The dynamics and trends in consumption of tobacco, electronic nicotine delivery systems (ENDS) and heated tobacco products (HTPs) are analyzed. MATERIALS AND METHODS: The surveys used representative samples formed on the basis of all public schools...

The African Cigarette Price Project is a project that collects tobacco prices from African countries. Amongst other things, the data enable users to estimate price differences across brands, urban/rural divides, types of packaging, retail types, and trends in price over time. A total of 215 354 individual prices were collected during the first twelve rounds of the project (collected biannually from 2016 to 2022). Data collection continues to date. Data have been collected from 19 African countries, with most data from South Africa, Zimbabwe, Lesotho, Namibia and Botswana...

BACKGROUND: Clinical practice guidelines (CPGs) synthesize high-quality information to support evidence-based clinical practice. In primary care, numerous CPGs must be integrated to address the needs of patients with multiple risks and conditions. The BETTER program aims to improve prevention and screening for cancer and chronic disease in primary care by synthesizing CPGs into integrated, actionable recommendations. We describe the process used to harmonize high-quality cancer and chronic disease prevention and screening (CCDPS) CPGs to update the BETTER program...

PURPOSE: To examine the effect of e-cigarette warning labels (EWLs) prior to the August 2018 FDA-warning label mandate to establish a baseline for future research. DESIGN: Cross-sectional survey. SETTING: United States. PARTICIPANTS: A cohort of adult participants in the Population Assessment of Tobacco and Health (PATH) study (n = 30,004) at Wave 4 (Dec 2016-Jan 2018). MEASURES: Correlates (e...

IMPORTANCE: The prevalence of e-cigarette use among US adults, especially young adults, is rising. Many would like to quit vaping nicotine but are unable to do so. Cytisinicline, a plant-based alkaloid, targets nicotinic acetylcholine receptors, reduces nicotine dependence, and helps adults to stop smoking cigarettes. Cytisinicline may also help e-cigarette users to quit vaping. OBJECTIVE: To determine the efficacy and safety of cytisinicline vs placebo to produce abstinence from e-cigarette use in adults seeking to quit vaping nicotine...

Adolescents with congenital heart disease (CHD) have elevated risk for acquired cardiovascular complications, increasing their vulnerability to e-cigarette-related health harms. Impulsivity and risky decision-making have been associated with adolescent substance use, but the relationships between these factors and e-cigarette-related outcomes among cardiovascular at-risk adolescents with CHD are unknown. This cross-sectional study aimed to (a) determine the associations of impulsivity and risky decision-making with e-cigarette-related outcomes (i...

BACKGROUND: Emerging data indicate that many adolescents and young adults ("youth") engage in infrequent, or occasional, e-cigarette use. However, little is known about this population as they are often subsumed into the broader "any past-30-day use" category used to define youth "current use." This study aimed to focus on infrequent e-cigarette use by youth, examining its correlates and transitional outcomes. METHODS: Participants were from a prospective cohort study of youth (aged 15-24 at baseline)...

BACKGROUND: Although electronic cigarettes (e-cigarettes) appear to be effective in helping people who smoke to stop smoking, concerns about use of e-cigarettes among young people have led to restrictions on non-tobacco flavoured e-liquids in some countries and some US states. These restrictions could reduce the appeal of these products to non-smoking youth but could have negative consequences for people who smoke or use e-cigarettes. METHODS: In this mixed methods study, we recruited UK adults who smoked or used to smoke and subsequently vaped to explore their opinions of unflavoured e-liquids and their beliefs about how they would be impacted by hypothetical e-liquid flavour restrictions...

INTRODUCTION: Massachusetts (MA) enacted statewide regulation on all flavored tobacco products in June 2020. Thereafter, electronic cigarettes (e-cigarettes) labeled 'clear' emerged on the market. We aimed to combine cardiovascular health effects with chemical analysis of 'clear' e-cigarettes. METHODS: We measured acute changes in blood pressure and heart rate following a 10-minute structured use of participants' own e-cigarette, comparing 'clear' e-cigarette users with other flavored e-cigarette users and non-users...

INTRODUCTION: Tobacco smoke is a major health risk factor for smokers but also for non-smokers due to passive smoking. These risks come from conventional cigarette smoke but also from aerosol produced by electronic cigarettes and heated tobacco products (HTPs). The aim of this study was to investigate population knowledge about the adverse effects of passive smoking from traditional cigarettes, electronic cigarettes, and HTPs. METHODS: Between February and October 2023, 504 subjects among the general population responded to a questionnaire with 8 questions in Italian, via a link to the Google Forms platform...

BACKGROUND AND PURPOSE: Traumatic brain injury (TBI) causes lifelong physical and psychological dysfunction in affected individuals. The current study investigated the effects of chronic nicotine exposure via E-cigarettes (E-cig) (vaping) on TBI-associated behavioural and biochemical changes. EXPERIMENTAL APPROACH: Adult C57/BL6J male mice were subjected to controlled cortical impact (CCI) followed by daily exposure to E-cig vapour for 6 weeks. Sensorimotor functions, locomotion, and sociability were subsequently evaluated by nesting, open field, and social approach tests, respectively...

BACKGROUND: Increasing numbers of young people (adolescents aged 12-17 years and young adults aged 18-25 years) are using e-cigarettes. Although the extent of the health effects is currently unknown, young people are at risk of developing nicotine dependence and, as a result, find it difficult to cease use of e-cigarettes. They might seek help from their general practitioner (GP) to do so. OBJECTIVE: This article summarises the available evidence for e-cigarette cessation in young people and suggests a rational approach to assist GPs seeing young people seeking help for e-cigarette cessation...

INTRODUCTION: Nicotine withdrawal is a well-established construct that prompts continued nicotine product use and contributes to failed cessation efforts. Despite ongoing public health concerns about nicotine e-cigarette use in adolescents and young adults (AYAs), no psychometrically-sound measure of nicotine e-cigarette withdrawal exists for this population. METHODS: A mixed methods approach comprising a literature review to identify existing nicotine withdrawal items; subject matter expert feedback on existing items and novel item generation; cognitive interviews assessing the measure's instructions, items, and response options; and a large quantitative validation survey (N = 997) was employed to develop the novel retrospective measure of nicotine e-cigarette withdrawal...
