Knowledge and Use of Electronic Cigarettes in Young Adults in the United Arab Emirates, Particularly during the COVID-19 Pandemic

(1) Background: The popularity of electronic cigarettes (e-cigarettes) has recently increased. Although they are less harmful than regular cigarettes, they still cause health consequences and their use for smoking cessation is inconclusive. The objective of this study was to evaluate patterns of use, knowledge about, and attitude towards e-cigarettes among youth in the United Arab Emirates (UAE) while also researching the impact of the COVID-19 pandemic on smoking behavior. (2) Methods: An online cross-sectional survey was distributed across three major universities in the UAE (n = 240) between March and November 2021. Descriptive analysis, comparison across gender and nationality groups, and correlates between 30-day e-cigarette use and self-reported increases in nicotine consumption during the pandemic were studied. (3) Results: About 37% of students had used an e-cigarette in their lifetime, and 23% had smoked e-cigarettes in the past month. During the pandemic, 52% of university students self-reported no change in nicotine consumption, while only 17.5% had reported an increase. The current smoking of regular cigarettes, waterpipe, and medwakh increased the odds of having an increase in smoking during the pandemic by 5.3 times. (4) Conclusions: The findings inform about youth behavior and knowledge about vaping in the UAE and could also support the development of awareness interventions.
