I think Covid & climate induced wildfires have caused a real shift in the perception of air quality. In that we've all realized its really shit. CO² levels alone in crowded buildings commonly exceed thresholds recognized to cause minor cognitive deficits. Even in hospital settings most modern buildings have a pretty pathetic exchange & filtration rate with the outside air, and thats saying nothing of the basically non-existant regulations on other public or communal spaces.

Modern society requires drastic retrofits and rebuildings to basically everywhere to have decent quality air. Under global communism there will be robust enough filtration systems to let me smoke a fat blunt at Kroger.

Edit:Also diner food hits different when the cook gets ash in the pan. You just dont get it.
