Hey Dave,
When you quit smoking the cilia in your lungs that sweep the mucus up (and nasty bacteria) begin to repair themselves. While you were smoking you destroyed this body defense mechanism. It is a good thing. Your ciliatory escalator (yes, that's what it's called) is starting to function properly again.
As far as the smell goes, no idea. I did rewash all of my coats, but one in particular smelled pretty nasty next to the hand so I just washed it again. It was gone the second time.
