In addition to lost life, there is also a cost to quality of life. Air quality is one of the biggest contributors to the risk of senile dementia. But also the gas composition is known to affect cognition in the short run as well, with a measurable difference in cognitive tests when indoor CO2 is elevated.

No need to bring in effects to cognition, even. It just sucks to live in a place where “(tonight’s run|tomorrow’s hike) is canceled because the air quality is shit” is a thing.

  I'm not sure which claim you're looking for a citation for, but if it was the CO2 and cognition claim, then I have a few for you. This study made quite a few ripples when it came out: https://ehp.niehs.nih.gov/doi/10.1289/ehp.1510037 https://ehp.niehs.nih.gov/doi/10.1289/ehp.1510037 > On average, cognitive scores were 61% higher on the Green building day and 101% higher on the two Green+ building days than on the Conventional building day (p < 0.0001). VOCs [volatile organic compounds] and CO2 were independently associated with cognitive scores. There was also this one, about decision making: https://ehp.niehs.nih.gov/doi/10.1289/ehp.1104789 https://ehp.niehs.nih.gov/doi/10.1289/ehp.1104789 > Relative to 600 ppm, at 1,000 ppm CO2, moderate and statistically significant decrements occurred in six of nine scales of decision-making performance. At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06–0.56), but performance on the focused activity scale increased. This one is a high-level overview of the literature on air pollution and health: https://ehp.niehs.nih.gov/doi/10.1289/EHP4869 https://ehp.niehs.nih.gov/doi/10.1289/EHP4869

Could air quality degradation leading to this be caused by a lifetime of smoking cigarettes indoors?

I think it’s highly likely that in 20 years we will view diesel cars like we do leaded fuel. An insanely bad idea that we knew was bad at the time but continued to use.
