This information should be approached with caution, as current scientific data is limited. However, preliminary Chinese and American studies suggest nicotine may offer protection against COVID-19.
"Nicotine might protect, not tobacco smoke," emphasized Marion Adler, a tobacco specialist at Antoine Béclère Hospital in Clamart. She stressed the need to remain very careful.
Dr. Adler explained the potential mechanism: This could involve regulation of ACE2 receptors, which might reduce inflammatory responses and provide protection through nicotine. "But we can't draw conclusions yet—it's far too early. Stay scientific amid the speculation."
Smokers are not listed among high-risk patients by France's High Council for Public Health, as noted in detailed Yahoo France coverage. Professor Jean-François Delfraissy, president of the scientific council, observed on France Info on April 8: "the vast majority of serious cases were non-smokers." He strongly advised against starting to smoke.
Tobacco use heightens COVID-19 risks by impairing the immune system, bronchial tree, and lungs, according to the National Committee Against Tobacco (CNCT). Smokers face more severe, prolonged infections and higher contagion risk from smoking-related coughs.
Quit now: Nicotine replacement therapies remain available at pharmacies, fully reimbursed by health insurance and mutual plans with a prescription, alongside smoking cessation treatments.
