To be fair, the smoking laws here in Norway are a little more relaxed than they were when i was living in the US. Want to smoke in the hospital parking lot? You'll get escorted off. Same for areas outside some airports, but I can smoke outside the airport here in Trondheim before I get on the bus. No real problem smoking on the sidewalks downtown. Some ask you to go away from the doors, but that isn't a real issue and I find it reasonable. Companies aren't firing people for smoking, and I don't find they tell folks they simply cannot smoke during the work day (including lunch).

You can smoke in dedicated smoking areas outside, but it's actually not allowed to smoke on bus-/train stops/sidewalks etc. There are just no one to enforce it.

I guess the places where you get escorted from in the US are privately owned and not due to a law (but I could be wrong). The companies firing you for smoking might also have to do with a bit stronger labor laws in Norway :)
