French researchers to test nicotine patches on coronavirus patients
Study – which stresses serious health risks of smoking – suggest substance in tobacco may lower risk of getting coronavirus
French researchers are planning to test nicotine patches on coronavirus patients and frontline health workers after a study suggested smokers may be much less at risk of contracting the virus.
The study at a major Paris hospital suggests a substance in tobacco – possibly nicotine – may be stopping patients who smoke from catching Covid-19. Clinical trials of nicotine patches are awaiting the approval of the country’s health authorities.
...
Taking into account the age and sex of the patients, the researchers discovered the number of smokers was much lower than that in the general population estimated by the French health authority Santé Publique France at about 40% for those aged 44-53 and between 8.8% and 11.3% for those aged 65-75.
