Given other people around me talking about treating their long covid with nicotine since it went through social media last year, I suppose you don't know about / didn't try the Natto (nattokinase) [1] / NAC route [2] (for which there were early studies showing they can dissolve the SARS-Cov2 spike protein)..? Or does the community consider that a dead end by now?
That there is a political echo chamber-driven division between those routes is a bit strange and dangerous, isn't it. With nicotine you will need to be careful about its effects on blood pressure, and it would be better to not even think about vaping (some of the flavoured products could be equally/more addictive to/than cigarettes [3]).
