A relatively low smoking prevalence was observed among COronaVIrus Disease 19 (COVID-19) patients [1]. Some researchers, whose link to the tobacco industry cannot be ruled out in some cases [2], speculated that nicotine could have a protective effect against Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV-2) infection and COVID-19 disease, and consequently that electronic cigarettes (e-cig) could reduce the risk of SARS-CoV-2 infection [3–5]. Also, a systematic review of the literature suggested that nicotine containing products might be used to support smokers to stop as part of public health efforts during the COVID‐19 pandemic [1].
