I lived in Amsterdam for 7 years and they were talking about this when I left in 06. The coffeeshop owners were planning on separating the smoking rooms in such a way that the employees wouldn't have to be in the room with the smoke.

Wonder if they started selling more joints without tobacco? I would say 8 out of 10 places didn't even offer pre-rolled without tobacco in it when I was there. Of course, pre-rolled is a ripoff, we always just got our grams.
