Today I came across this study paper:

 

COVID-19 and smoking: A systematic review of the evidence

 

http://www.tobaccoin...119324,0,2.html

 

Excerpts from results of five different studies:

 

"Among the 191 patients, there were 54 deaths, while 137 survived. Among those that died, 9% were current smokers compared to 4% among those that survived, . . ."

 

"Similarly, Zhang et al.10 presented clinical characteristics of 140 patients with COVID-19. The results showed that among severe patients (n=58), 3.4% were current smokers and 6.9% were former smokers, in contrast to non-severe patients (n=82) among which 0% were current smokers and 3.7% were former smokers, . . ."

 

"In this study, none of those who needed to be admitted to an ICU (n=13) was a current smoker."

 

"Among the patients with severe symptoms, 16.9% were current smokers and 5.2% were former smokers, in contrast to patients with non-severe symptoms where 11.8% were current smokers and 1.3% were former smokers. Additionally, in the group of patients that either needed mechanical ventilation, admission to an ICU or died, 25.5% were current smokers and 7.6% were former smokers."

 

". . . among their population of 78 patients with COVID-19 that the adverse outcome group had a significantly higher proportion of patients with a history of smoking (27.3%) than the group that showed improvement or stabilization (3.0%), . . ."

 

 

Interesting, isn't it?  Hmmm...

I did some more digging, and found this other one, that even has U.S. data

 

Smoking, vaping and hospitalization for COVID-19

https://www.qeios.com/read/Z69O8A.13

 

Excerpt:

 

"The prevalence of current smoking ranged from 1.4% to 12.6%. The random effect pooled prevalence of current smoking was 6.5% (95%CI: 4.9-8.2%). This preliminary analysis does not support the argument that current smoking is a risk factor for hospitalization for COVID-19. Instead, these consistent observations, which are further emphasized by the low prevalence of current smoking among COVID-19 patients in the US (1.3%), raises the hypothesis that nicotine may have beneficial effects on COVID-19."

Another one:

The Characteristics of 50 Hospitalized COVID-19 Patients With and Without ARDS

https://www.aerztebl.../article/213455

 

If you look at Table 1 "Patient Characteristics," it shows that out of the 50 patients, only 3 were smokers and none of them developed ARDS.
