“This preliminary analysis does not support the argument that current smoking is a risk factor for hospitalisation for COVID-19,” the researchers wrote.
“Instead, these consistent observations, which are further emphasised by the low prevalence of current smoking among COVID-19 patients in the US (1.3 per cent), raises the hypothesis that nicotine may have beneficial effects on COVID-19.”
However, the analysis does hold some limitations. For instance, the research paper hasn’t been reviewed by other scientists – yet.
And the data is still limited. The researchers admitted: “The accuracy of the recorded smoking status needs to be determined.”
