It 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.

The study is done with a Covid positive population.

They didn’t study if people who smoked where less likely to get Covid. The study goal, as I understand it, was to theorize the idea that smoking serves as some sort of protection leading to less severe symptoms.

Otherwise the study wouldn’t make sense. The study must have clearly accounted for ratios in the smoking general population against the sample population. That’s the only way it makes sense.

I’m curious what makes you think that smokers isolated earlier than anyone else. I don’t think being a smoker makes you more self-aware of your own health. If anything is quite the contrary.

Interesting, 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 (manus…

Not in medical field, but nicotine is generally biotoxic and used as a pesticide so i'm not at all surprised. Detriments to any symbiotic microorganisms aside, regularly spraying the lungs and other airways with a light coating of biotoxic film seems a good way to generally inhibit replication or damage any negative bioparticles, so long as the damage doesn't overwhelmingly interfere with the smoker's own biological functions and weaken the overall system ...

Very few habits are hand to mouth in the way smoking does. Smokers will touch their hands to their mouths hundreds of times a day...without a thought as to where that hand has been.

So start taking nicotine lozenges as a prophylactic?

Hypothesis: 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.

Same here, although I already suspected it based on the fact that Japan's death total is very low; smoking is more prevalent in Japan than most advanced economies, I believe.

Would orally ingested nicotine protect lungs the same way that inhaled nicotine does?

The smokers in my apartment building go outside everyday and make social contact with other smokers hanging out outside the door.

The OP does have a point. You cannot control for the social isolation factor because there is no data on it.

The people who isolate with 100% success never get COVID and thus are missing from the sample population.

It is also easier to isolate than to give up smoking.

engaging in a risk factor is not a condition.
