Does nicotine help against the new coronavirus?
Although selective cytokine blockers (eg, IL1-receptor antagonist anakinra or anti-IL6 tocilizumab) have been proposed for the control of Covid-19 cytokine storm, their efficacy is still to be explored. Interestingly, 𝛼7 agonists, including nicotine, have proven to be effective in reducing macrophage cytokine production and inflammation in animal models of pancreatitis [32] and peritonitis [33]. In this setting, a nicotinic treatment that might possibly antagonize the blocking action of SARS-CoV-2 on the AChR through a possible modulation of the ACE2 – nAChR interaction, would act earlier than anti-cytokine therapies. nAChR modulation by Covid-19 might tentatively account for the hyperinflammatory features observed in a subgroup of Covid-19 patients, mimicking bona fide the macrophage activation syndrome.
A nicotinic hypothesis for Covid-19 with preventive and therapeutic implications
Abstract
There is an urgent need to address the devastating pandemic, COVID-19, caused by SARS-CoV-2. The efforts to understand the details of this disease in hope of providing effective treatments are commendable. It is clear now that the virus can cause far more damage in patients with comorbid conditions-particularly in those with respiratory, cardiovascular, or immune-compromised system-than in patients without such comorbidities. Drug use can further exacerbate the condition. In this regard, the ill effects of smoking are amply documented, and no doubt can be a confounding factor in COVID-19 progression. Although conflicting hypotheses on the potential role of nicotine in COVID-19 pathology have recently been offered, we believe that nicotine itself, through its interaction with the nicotinic cholinergic system, as well as ACE2, may not only be of use in a variety of neuropsychiatric and neurodegenerative diseases, but may also be of potential use in COVID-19. Thus, on one hand, while we strongly support smoking cessation as a means of harm reduction associated with COVID-19, on the other hand, we support a potential therapeutic role for nicotine, nicotinic agonists, or positive allosteric modulators of nicotinic cholinergic receptors in COVID-19, owing to their varied effects including mood regulation, anti-inflammatory, and purported interference with SARS-CoV-2 entry and/or replication.

that include ACE2 receptor protection and possibly radioactivity in tobacco could be blocking the Covid receptors themselves

You are correct sir! Seat belt laws set the precedence for anti-tobacco laws.

in a word nicotine, years ago i read a article and heard it on right wing whacko radio that nicotine it was the suspected reason that smokers weren't getting sick like non smokers during not sure what kind of out break it was then, and that smokers that worked in some chemical plants didn't get as sick as non smokers due to the chemicals.
that was right before the big push / ban on smoking and the taxes federal and states started putting on them to make people stop.
turns out there might have been something to it. not so much the smoking and all the other sh@@ put in cigarettes and the effects that they cause for smokers it's the nicotine.
a abstract and a articles about it.
first the articles,
