Introduction and objective:
Electronic cigarettes (e-cigarettes) have become the most common form of nicotine consumption among adolescents and young adults. Little is known about the impact of government-imposed restrictions during the COVID-19 pandemic on the vaping behaviour of both adolescents and adults. This study aimed to explore scientific research concerning the prevalence of e-cigarette usage following the onset of the COVID-19 pandemic.

Review methods:
A systematic, comprehensive search of English-language literature in online databases (PubMed, Web of Science, Elsevier, Scopus, Google Scholar) was conducted from January 2023 – June 2023. A key word search was conducted for publications published from March 2020 when the COVID-19 pandemic was announced to December 2022.

Brief description of the state of knowledge:
Most of the analyzed articles reported changes in e-cigarette use during the COVID-19 pandemic. The reasons for the increase in the use of e-cigarettes during the pandemic included: boredom, loneliness, stress caused by lockdown, and online purchases. The decrease in e-cigarette consumption is attributed to stayat-home orders causing barriers to e-cigarette access, limited peer group gatherings, and increased time spent at home with the family. The Covid-19 pandemic also impacted attempts to stop the use of e-cigarettes.

Understanding the factors that influenced changes in e-cigarette use during the COVID-19 pandemic should be used to develop prevention programmes for adolescents and young adults. Educating young people and increasing knowledge about the harmful effects of using e-cigarettes may contribute to reducing the initiation of using e-cigarettes, and is a strong incentive to quit smoking.
