This is why I get nauseous when I am around smokers.

I remember living in a big city when the law was passed. The city hall hired cleaners to remove the smell. I can’t confirm the whole building as it’s absolutely massive but I do remember seeing the smallest areas being scrubbed. Out of every building in the area it turned out the absolute best. 1 mcdonalds ended up remodeling the whole place but the smell was still a little faint.
