Twitter Misinformation Discourses About Vaping: Systematic Content Analysis

Twitter Misinformation Discourses About Vaping: Systematic Content Analysis

Electronic nicotine delivery systems (ENDS), also known as e-cigarettes, were introduced as a means of harm reduction or cessation tool for cigarette smokers. However, e-cigarettes and especially vaping products have also become highly popular among those who previously did not use nicotine products including adolescents and youth [1,2]. In the United States, the percentage of middle and high school students who have ever used ENDS rose from 10% in 2011 to more than 27% in 2019 [1,3,4].

Using a Novel Connected Device for the Collection of Puffing Topography Data for the Vuse Solo Electronic Nicotine Delivery System in a Real-World Setting: Prospective Ambulatory Clinical Study

Using a Novel Connected Device for the Collection of Puffing Topography Data for the Vuse Solo Electronic Nicotine Delivery System in a Real-World Setting: Prospective Ambulatory Clinical Study

Conversely, understanding the use of ENDS products extends beyond understanding a single use of the product with the context of a consumer’s normal environment removed. A number of studies have reported ENDS use characteristics in clinical settings with defined periods of use [6,28,29], but only more recently have studies been able to provide topography data from ENDS products used in an ambulatory fashion [20,30-33].

e-Cigarette Use and the Cessation of Tobacco Cigarette Smoking: Protocol for an Umbrella Review

e-Cigarette Use and the Cessation of Tobacco Cigarette Smoking: Protocol for an Umbrella Review

e-Cigarettes, termed electronic nicotine delivery systems (ENDS), were invented in 2003 to be a cigarette cessation device [1]. The substantially reduced toxicant profile of ENDS compared to cigarettes [2,3] has motivated researchers to investigate its potential for supporting cigarette smoking cessation. As the number of clinical studies piled up, the first systematic review on ENDS for smoking cessation was published in 2014 by the Cochrane Group [4], and 21 systematic reviews were published by 2017 [5].

A New Questionnaire to Assess Respiratory Symptoms (The Respiratory Symptom Experience Scale): Quantitative Psychometric Assessment and Validation Study

A New Questionnaire to Assess Respiratory Symptoms (The Respiratory Symptom Experience Scale): Quantitative Psychometric Assessment and Validation Study

Electronic nicotine delivery systems (ENDS) deliver nicotine without many of the toxic combustion products associated with smoking and are intended to offer adult smokers a lower-risk alternative to smoking. Reviews by national health authorities, such as the National Academies of Sciences, Engineering, and Medicine [9] and the Royal College of Physicians [10], conclude that ENDS reduce users’ exposure to toxicants and carcinogens compared with combustible cigarettes.

The Vaping and Patterns of e-Cigarette Use Research Study: Protocol for a Web-Based Cohort Study

The Vaping and Patterns of e-Cigarette Use Research Study: Protocol for a Web-Based Cohort Study

Electronic nicotine delivery systems (ENDS) are e-cigarettes that heat a nicotine liquid into an aerosol that can be inhaled by a user, whereas electronic nonnicotine delivery systems (ENNDS) heat a nonnicotine-containing liquid (ENNDS are included in the study as ENDS users may become ENNDS users and vice versa). Both include a battery that powers a heating element, such as a metal coil, which is in contact with the liquid.

Identifying Electronic Nicotine Delivery System Brands and Flavors on Instagram: Natural Language Processing Analysis

Identifying Electronic Nicotine Delivery System Brands and Flavors on Instagram: Natural Language Processing Analysis

Social media marketing of ENDS products coincides with the increasing prevalence of ENDS use among youths and young adults [7-11]. In 2011, current ENDS use (ie, past 30-day use) was 1.5% and 4.9% among high schoolers and middle schoolers, respectively [7], whereas, in 2019, ENDS use was 27.5% and 10.5% among high school and middle schoolers [8]. In 2013 and 2014, current ENDS use was 12.5% among young adults aged 18 to 24 years [9], whereas in 2019, ENDS use was 24.5% among the same age group [10].

Respiratory and Cardiovascular Health Effects of e-Cigarette Substitution: Protocol for Two Living Systematic Reviews

Respiratory and Cardiovascular Health Effects of e-Cigarette Substitution: Protocol for Two Living Systematic Reviews

The acceptability of ENDS among people who smoke is demonstrated by its rapid uptake; in 2018, there were 41 million people using ENDS compared with 7 million users in 2011 [13]. Clinicians want to know the health effects of ENDS use, asking “are e-cigarettes marginally safer, thus still too risky to substitute for combustible products, or are they substantially safer?” [14]. There have been 3 recent systematic reviews published on the respiratory effects of ENDS.

Investigating the Attitudes of Adolescents and Young Adults Towards JUUL: Computational Study Using Twitter Data

This increase was primarily influenced by the use of electronic nicotine delivery systems (ENDS). Current use of ENDS among high school students increased from approximately 1.5% in 2011 [1] to approximately 27.5% in 2019 [3].
