Background: Electronic cigarette (e-cigarette) use is becoming popular among undergraduate students in Nigeria with a tendency for escalation because of the coronavirus disease 2019 (COVID-19) pandemic. Aim: The aim of this study was to assess electronic cigarette use in COVID-19 era among undergraduate students of a tertiary institution in Lagos state, Southwestern Nigeria.

Methods: The study design was a descriptive cross-sectional study with a pretested, structured, close- and open-ended self-administered questionnaire used for collection of data on knowledge, attitude and use of e-cigarettes. Results: Data from 183 respondents were analysed. The mean age of respondents was 24.8 ± 3.38 years, most (63%) of whom were males. The prevalence of ever-use of e-cigarettes was 15.3% of which 60.7% reported increased use of e-cigarettes since the COVID-19 pandemic. Age, education, tribe and religion ( p < 0.001) were significantly associated with higher odds of use of e-cigarettes.
