Yes
No, no there isn't and I find this to be a rather stupid measure given that you can smoke in most bars in Belgium. I run through this airport at least once every two weeks and every single time I look for a smoking area, hoping, dreaming that they have come to their senses. They haven't.

No smoking facilities. Do a check in, go outside the building, have a smoke or ten and then go through security.
