Poor Naemanson - that's often the trouble with the forum. You ask a question, nobody knows for sure, but everybody gives a statement slightly related to your question, and finally, perhaps, you get a correct answer. Wolfgang preceded me, I only have to add a few notices.
Since the formation of a European legislation in the Community you may observe a tendency to ban smoking in the entire European Community for health reasons. Differences between the usages and laws of the member countries will disappear in some years.
The amount of ingredients like tar and nicotin will be reduced again at Jan. 1, 2003. Several brands of cigarettes like my favourite pure Orientals and Virginians won't be produced any more.
Railway stations in Germany will be smoke free soon, they're working on it.
In better restaurants it was always considered bad style to smoke at table, but since there are no ashtrays, addicts sometimes use the saucers.
