E-cigarettes

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...

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...

INTRODUCTION: Addressing cigarette and e-cigarette use in China is key to reducing the global tobacco epidemic. Marketing exposure is one causal factor for adolescent smoking and e-cigarette use. Currently, China restricts cigarette and e-cigarette ads in public places and online; however, there may not be full policy compliance. We collected real-time data in the natural environment to estimate how much and where Chinese adolescents - a group susceptible to smoking and e-cigarette use - are exposed to cigarette and e-cigarette marketing to inform policy responses...

INTRODUCTION AND IMPORTANCE: While vaping has increased significantly among young individuals, the effects of vape aerosol constituents on cardiac electrophysiological dynamics remain unknown. CASE PRESENTATION: A 22-year-old female with a history of energy vaping presented with cardiac arrest. Found to have no pulse, CPR was started and an initial rhythm of ventricular tachycardia was obtained. Shock was administered with a follow-up rhythm of ventricular fibrillation...

Background: Recent studies show e-cigarette (EC) users have increased rates of chronic bronchitic symptoms that may be associated with depressed mucociliary clearance (MCC). Little is known about the acute or chronic effects of EC inhalation on in vivo MCC. Methods: In vivo MCC was measured in young adult vapers ( n  = 5 males, mean age = 21) after controlled inhalation of a radiolabeled (Tc99m sulfur colloid) aerosol. Whole-lung clearance of radiolabeled deposited particles was measured over a 90-minute period for baseline MCC and associated with controlled periodic vaping over the first 60 minutes of MCC measurements...

INTRODUCTION: Providing access to a vape shop-based smoking cessation intervention may simultaneously increase e-cigarette use and increase the effectiveness of e-cigarettes for smoking cessation. The aim of this study was to identify the most important elements of vape shop-based smoking intervention to stakeholders who would be involved in delivering or accessing such an intervention. METHODS: We conducted a three-round Delphi study of vape shop staff (n=40), stop smoking professionals and tobacco control leads (n=30), and smokers, vapers and dual users (n=30) in the United Kingdom in May-August 2021...

BACKGROUND AND OBJECTIVES: Limited longitudinal research has examined differential interpersonal and intrapersonal correlates of young adult use and use frequency of cigarettes, e-cigarettes, and cannabis. This study aimed to address these limitations. METHODS: We analyzed five waves of longitudinal data (2018-2020) among 3006 US young adults (Mage  = 24.55, 44% male, 32% sexual minority, ~30% racial/ethnic minority). Two-part latent growth models examined likelihood of past-month cigarette, e-cigarette, and cannabis use (binary part) and days used (continuous part) and identified predictors (depressive symptoms, personality traits, adverse childhood experiences [ACEs], parental use) of baseline use and changes over time...

BACKGROUND: Australia introduced a prescription only policy for e-cigarettes in 2011 to prevent uptake among youth while allowing smokers to access e-cigarettes for cessation. This is one of the restrictive forms of regulation for e-cigarettes recommended by the World Health Organisation. AIMS: To assess whether the policy has prevented e-cigarette youth uptake and facilitated smokers' access to e-cigarettes for cessation; and to examine a proposed toughening of the policy...

BACKGROUND: Youth vaping poses a significant public health concern as metals have been detected in e-cigarette aerosols and liquids. This study investigated factors associated with biomarkers of metal exposure. METHODS: Data were drawn from Wave 5 of the Population Assessment of Tobacco and Health (PATH) Study Youth Panel, a nationally representative sample of US adolescents aged 13-17 years. Urinary biomarkers of exposure to cadmium, lead, and uranium were assessed by vaping frequency (occasional (1-5 days), intermittent (6-19 days), and frequent (20+ days)) in the past 30 days and flavour type (menthol/mint, fruit, and sweet)...

The prevalence of electronic cigarette use has been declared an epidemic by the U.S. Surgeon General in 2018, particularly among youth aged 18-24 years old. Little is known about the differential use of e-cigarettes by different groups. PubMed, Cochrane, and Google Scholar were used to find relevant articles. A total of 77 articles were included. The extant literature reveals disparities in e-cigarette use by race/ethnicity and sexuality/gender. There are conflicting conclusions regarding disparities by socioeconomic status...
