That makes sense!
Also, there have been the strange reports of lower than average incidence of Covid19 illness among smokers. This might be related to nicotine’s retardation of the clot-formation property of thrombin.

but I thought it was even lower among EX smokers.
Not about nicotine but about the lung receptors.
