Kate, can anyone except your family smell this smoke? If your house was new when you bought it and you've been smelling it for 10 years, and none of your passed over loved ones smoked, it may be something in the building materials of the house. Usually when someone smells smoke, it only last for a little while and they can identify it with a loved one. Every once in a while I smell cherry tobacco and my Dad used to smoke a pipe with cherry tobacco. It only last for a moment though.
