Abstract
Web-based samples of e-cigarette users commonly report significant vaping-related health improvements (HIs) and mild adverse events (AEs). This cross-sectional study with in-person interviewing data collection examined self-reported AEs and perceived HIs among Hungarian adult current daily exclusive e-cigarette (n = 65) and dual users (n = 127), and former daily e-cigarette users (n = 91) in 2018. Logistic regression was used to evaluate associations between reporting any AEs/HIs, vaping status, and covariates. More former users (52.7%) reported AEs than current users (39.6%; p = 0.038). Exclusive and dual daily users reported similar rates of AEs (44.6% and 37.0%, respectively; p = 0.308). More current users (46.9%) experienced HIs than former users (35.2%; p = 0.064). Exclusive daily users were more likely to report HIs than dual users (63.1% versus 38.6%; p = 0.001). Former user status and smoking cessation/reduction reasons increased the odds of reporting AEs, whereas nicotine-containing e-liquid use and older age decreased the odds of reporting AEs. Exclusive vaper status, using advanced generation devices, and smoking cessation/reduction reasons increased the odds of experiencing HIs. This study, which used a traditional data collection methodology, found a higher rate of AEs and a lower rate of HIs compared to web-based surveys. Our results highlight that experiencing AEs and HIs is affected by users’ characteristics, in addition to the device and e-liquid type.
Highlights
The comparison of former and current daily e-cigarette users displayed in Table 1 revealed that former daily users are similar to current daily users in many demographic variables; former daily users reported the use of first- and second-generation e-cigarettes more frequently than current users
Our results suggest that young adult former daily e-cigarette users who used nicotine-free e-liquid, and initiated vaping to quit smoking or to reduce smoking, experienced more adverse events (AEs) during their previous daily vaper experiences
This study found that almost half of current daily e-cigarette users experienced any health improvement, and exclusive daily users reported higher rates (63%) than dual users
Summary
The popularity of electronic cigarette (e-cigarette) use is increasing, and many smokers are switching from combustible cigarettes (CCs) to e-cigarettes [1]. Due to the relatively limited number of studies, the rates of adverse events (AEs) or beneficial health impacts of e-cigarettes are not well known. Proponents of e-cigarettes place more emphasis on the positive aspects of their use, in the public media [2]. E-cigarettes are frequently positioned as a smoking cessation tool or as a clean, easy-to-use, and less harmful device. Side effects and possible harm associated with their use are rarely mentioned [3,4]. E-cigarettes have been commercially available for more than
