Smoking leads to the development of many respiratory system diseases, including chronic obstructive pulmonary disease and lung cancer. By hindering the protective mechanisms of our non-respiratory tract, it provides convenient conditions for respiratory infections. Smoking is an important risk factor for the infection and spread of COVID-19. Our historical information demonstrates that the use of tobacco products negatively affects patients' chances of survival during MERS-CoV and SARS-CoV, outbreaks of the same family as COVID-19. Considering the harms of smoking, it can be predicted that its exposure negatively affects the course of COVID-19 disease, both directly and indirectly. The aim of this review is to evaluate the relationship between smoking and COVID-19 in the light of current literature.
