RESUMEN
OBJECTIVE: To describe the possible risks associated to smoking in the spread and complications of Covid-19, em-phasizing in the benefits of quitting smoking. MATERIALS AND METHODS: The narrative review methodology and the established process for Cochrane rapid reviews were used. RESULTS: The scientific evidence related to smoking and Covid-19 remains limited. However, there is an already documented trend in cross-sectional, clinical studies and meta-analyses on the increased risk of adverse outcomes with Covid-19 associated with tobacco use. CONCLUSIONS: It is necessary to issue a warning that persons who smoke would have greater risks in the Covid-19 pandemic, which add to the many already known risks of tobacco use. Thus, quitting smoking becomes a relevant preventive measure to better confront SARS-CoV-2.
