I agree that if they are real bad, throw them away. But some people who smoke make quilts and don't realize how they smell. These quilts I would wash in a tub (soak, rinse, re-soak) with a gentle detergent and lay to dry. Sometimes you may need to add some vinegar in the rinse cycle if musty smell. If it doesn't work, then discard them. If the laundering has created some flaws, don't send to a LA. Perhaps you could do some very simple quilting to hold in place and donate to a homeless shelter. I'm sure it will still provide warmth and comfort and the recipient will not care that is doesn't have a super quilting style.
