Smoking was banned in public places a few months ago in France, though bars and restaurants are exempt until the end of the year. It doesn't seem to have had a huge effect as people ignore it, I saw quite a few people smoking in various places in CDG last week, including the people who work there.
One of my local restaurants decided ban smoking of its own accord a few weeks ago, I ate there last night and the place seemed bigger, it was then I realised that I could see to the entire restaurant, before visibility was limited by the cigarette haze
