While nicotine’s a decent poison, I was perhaps thinking that it’s all the other crap in a smoker’s lungs that make it inhospitable for the virus to survive for infection.
Maybe the smoke coats the lungs inner walls making it where the viral particles are less likely to penetrate.
Agreed. Smokers have a higher number of ACE2 receptors. It might just as well have to do with hemoglobin changes in smokers. Don’t know.
Maybe it could be ‘crap’ in the upper respiratory system which inhibits the bug from even making it to the lungs.
I have really bad allergy and sinus issues - nose always running, always getting stuff in the back of my throat. I don’t seem to catch colds, and have had the ‘flu maybe twice in the past ten years, where I felt bad enough to see a doc.
I”ve smoked off and on all of my life; but even when I’ve stopped for years at a time, all the allergy/sinus stuff was still there.
Maybe it’s a matter of some individuals being chronically sick all the time, and thus never becoming acutely sick - a perpetually charged immune system.
Who knows.
