Is smoking banned in most pubs in Ireland? Here in USA smoking laws are very strict and smoking not allowed in public places, restaurants, bars, etc. I AM GLAD OF THAT!!

All the folk music house concerts I have been to do not allow any smoking at all either (of course that is up to the owner of the home.)
Some home owners do not want you smoking just outside their home either and you would have to go out to the sidewalk (away from the homeowners actual property to smoke) because if people stand just outside the front door it can still drift inside - so that is the reason they want people to walk some distance from the house itself.

Some transit hubs (where multiple bus routes) come into one area usually ban smoking too even though it is outside. You cannot smoke unless you are out of the transit hub area altogether and away from where a lot of people are standing waiting for different bus routes.
