“Smoking Protected Against Covid” #explain. Sources- PMID 36434073 https://doi.org/10.1183/13993003.02144-2020 theovon on TT Early in the pandemic, a few small observational studies sparked widespread media attention by suggesting that active smokers were unexpectedly underrepresented among hospitalized COVID-19 patients. This led to the controversial hypothesis that nicotine might somehow block the virus from binding to cellular receptors, potentially offering a protective effect against the infection. However, a prominent paper promoting this theory was swiftly retracted by a major medical journal after an investigation revealed a massive, undisclosed conflict of interest. Several of the study’s authors had deep financial ties to the tobacco industry, fundamentally compromising the integrity and objectivity of the research. Once rigorous, large-scale epidemiological studies were conducted without industry interference, the scientific consensus entirely dismantled this protective hypothesis. These comprehensive analyses clearly demonstrated that the initial findings were statistically flawed and heavily biased by confounding variables, such as smokers misreporting their habits or having shorter life expectancies. In reality, smoking actively damages the respiratory system and impairs immune function, making individuals significantly more vulnerable to severe respiratory distress. The global medical community now definitively recognizes that smoking drastically increases, rather than decreases, the risk of suffering severe complications and fatal outcomes from a COVID-19 infection. #science #smoking #health
