Removing Cigarette Smoke Odor from Leather

Is there anything that I can use to get rid of the smell of cigerettes from a leather jacket?

YUCK. Unfortunately, the smell just has to fade. You can help it along by cleaning your jacket, either by using saddle soap as directed, or by having it cleaned by a professional leather cleaner, but depending on the porousness of the leather (lambskin, for example, is very porous), it may be a permanent part of your jacket.
