“The effect is significant. It divides the risk by five for ambulatory patients and by four for those admitted to hospital”

I’ll take a wild guess. The nicotine monopolizes the ACE-2’s, making a ‘free table’ harder for the virus to find?
ok, another one - nicotine is a pesticide and adapts as a systemic pesticide - ivermectin is also a pesticide (parasiticide) so is nicotine acting in a manner similar to ivermectin?
It’s also an antimicrobial. And smoking alters the microbiome of the entire respiratory tract including lowering the prevalence of prevotella.
I’m guessing it’s a combination of both. Hopefully this will be studied more now because it seems significant.
