The consequences are non existent for almost everyone. How many people have issues with strong causal link to indoor NO2 pollution in houses with vented gas appliances? Leaving that aside, lots of costs are socialized so why are we randomly picking out this one? Why not start banning specific recipes and ingredients if we are so concerned about socialized health costs? No more fried chicken for anyone! To me these bans and taxes are just political cohorts with power retaining their private benefit without restraint while restricting others who think and live differently.
