#2Hypothesis: if you have any pre-existing lung conditions, you are more likely to quit smoking. In other words, if you're the sort with pre-existing conditions that make you more likely to be hospitalized if you get Covid-19, then you would be more likely to have quit smoking (or died before now if you didn't).
Still an interesting result, but not, needless to say, a reason to start smoking.

I find it interesting that smoking itself isn't a pre-existing condition that makes you more likely to be hospitalized if you get Covid-19.

#4Interesting, they hypothesize that nicotine is responsible:
> There are however, sufficient scientific data to suggest that smoking protection is likely to be mediated by nicotine. SARS-CoV2 is known to use the angiotensin converting enzyme 2 (ACE2) receptor for cell entry[14-16], and there is evidence that nicotine modulates ACE2 expression[17]which could in turn modulate the nicotinic acetyl choline receptor (manuscript submitted).

I believe they raised and tried to address this confounding factor by determining whether or not one is a smoker based on a date prior to COVID-19 hitting. But I only skimmed it, so can’t be sure what they did.

#6It doesn't seem to take the social aspects of smoking into account. In a sense, smokers were already doing social isolation.
I'd bet that people who scream on street corners are less likely to contract it than people who spend time quietly on street corners.

#7I was joking the other day that it would be funny if the reason that Covid19 was less sever in Asian countries was not the high rate of mask usage but the high rate of smoking!

digs aside, this is highly culturally dependent - before smoking was quasi-taboo in the west, smokers were often more social and smoking was a 'good' way to meet people - just join the local smoking circle outside. Same is likely still true in less smoking hostile countries.

While non-smokers may try to avoid smokers, smokers frequently end up quite close to other smokers in any designated smoking area.
