Study on smoking and coronavirus withdrawn due to link with tobacco industry – Wel.nl

Last year, a few studies appeared that claimed that smokers have no additional risk of becoming seriously ill from the coronavirus and that they would become infected less often. At least one of those studies has now been withdrawn due to ties to the tobacco industry.

In that study, scientists stated that smokers were 23 percent less likely to contract Covid-19 compared to nonsmokers. The World Health Organization (WHO) warned that because smoking reduces lung function, the risk of severe Covid is higher.

But the paper, which appeared in the European Respiratory Journal last July, said that “smoking was not associated with a more negative outcome” when patients end up in hospital with corona. Smokers are also less likely to be infected. Various media wrote about the study.

The latest edition of the journal now states that the study has been withdrawn. “It has been brought to the attention of the editors that two of the investigators have not reported potential conflicts of interest.” One of them was a consultant for the tobacco industry, another worked for a company that sold electronic cigarettes.

An analysis by BMJ journal “identified multiple knowledge gaps and research errors that may falsely give the impression that smoking protects against Covid-19.”
