It was with great interest that we read the recent meta-analysis of 5 studies conducted in China in which Lippi et al conclude that active smoking is not associated with severity of coronavirus disease 2019 (Covid-19), with an odds ratio (OR) of 1.69 (95% CI, 0.41-6.42) [1].

This conclusion has been publicized in society, conveying the idea that smoking is not a risk factor for developing severe Covid-19. From a historical perspective, Lippi et al's conclusion has intriguing paralle- lisms with a long-standing, scientific battle already settled.
