Efficacy of Nicotine in Preventing COVID-19 Infection (NICOVID-PREV)
Daily active smokers are infrequent among outpatients or hospitalized patients with COVID-19. Several arguments suggest that nicotine is responsible for this protective effect via the nicotinic acetylcholine receptor (nAChR).
Nicotine may inhibit the penetration and spread of the virus and have a prophylactic effect in COVID-19 infection.
You don't have to smoke it, just can use a lozenge.
One commenter mentioned that nicotine helps remove the S2 proteins (the "other" spoke proteins) that accumulate to cause the long haul symptoms. Any info on that?
