stale cigarette smokeI've not yet run into any other kind.

I make it a point not take or borrow anything from smokers, or lend-to. Even books and electronics catch the odor. The jacket likely will have to be professionally cleaned considering how much residue is probably in it.

"... professionally cleaned ..."

Yup. And, for suede/leather, it will be expensive. No alternative, if you want to keep it. Good news is that they're pretty good at it. Be sure to inform them of your intent to get that odor out at the point of contract. If they flinch, go somewhere else.

Be sure to take the jacket to a cleaners that specializes in leather cleaning, or can send it to a place that does. A local store that sells a lot of leather jackets might be able to recommend a place.
