Without coffee, Washington state would be uninhabitable. I suppose leach fields and other sorts of chemical filters could prevent this and other chemical plumes. Moreover, I for one would be happy if I could retain my caffeine longer.
It's probably a reference to the dark damp winters.
I love living in Seattle, but I remember a December trip to LA a few years ago and thought "I can't find any good coffee here, but if I lived here I might not need good coffee to keep from killing myself"
