Smoking itself might not be fatal, but it probably won't help lung function any if you do catch a respiratory disease.
I will revise my question to this:
Of the people who have died from Batflu, what percentage smoked or have smoked?
I smoke ,but I've not died of Covid or smoking ,Yet
I did look into smoking with relation to Covid a while back,
at one stage, early on , France banned online sales of Nicotine patches, gum etc ,so they could use them as a treatment because there was some evidence ,albeit a small study about smokers being less prone to catching covid .
back then, people who smoked where less likely to catch covid than those who didn't smoke BUT some that did catch covid had a bad case of it .
not sure on figures with regards death from covid who smoked
google says "A review of 279 studies found that current smokers were at less risk of testing positive for SARS-CoV-2 than never smokers, while former smokers were at a greater risk of severe disease and hospitalization than never smokers."
https://www.news-medical.net/news/20201201/Does-smoking-increase-risk-of-COVID-19-hospitalization.aspx so I'll continue to smoke until long term data about covid is available
after that ,if I'm still alive
i'll decide then
