Can the insulation in an old building be recycled if the people were smokers?

I'm repurposing on old cabin for the lumber, to my surprise it has a lot of insulation in it. Can I reuse the insulation without polluting my new structure with cigerette chemicals? Will it always stink? will it off gas dangerous chemicals? Even if it is sealed in new walls will the smell or chemicals migrate through the new walls or wood ceiling in hot weather? It is foil lined on the inside of the room...can I wipe the foil with tsp and water and get rid of the smell before I reuse it? Or is this just a waste of effort with disapointing results? Kim
