One health benefit of cigarette smoking is actually two-in-one! What is a cigarette? It's a thing you burn. How do you kill things? You burn them! If the only air you breath first passes through the cherry of a cigarette, you can literally not get Covid and die. But that's just stage one. What's the other part of the cigarette? The part you don't light, unless you've been drinking too much? Right, the filter. Stage two. Even if somehow some sick bastard's coughed spittle boils it's way through the cherry and the viral load comes out unscathed, that's at least an inch of what I assume is fiberglass infused with chemicals that can stop fire. Fire! Viruses are killed by fire, so they have no chance. Plus I'm pretty sure I heard they have Vitamin C in them and stuff.
