Our home's smoke free. I wouldn't let anyone smoke in my games room or anywhere in the house. but it never comes up as an issue. The people in my circle of friends and family just do the right thing by popping outside for a few minutes.

Ultimately it's an individuals choice to smoke or not, but obviously it's not as widely accepted as in the past.

It doesn't worry me if someone chooses to smoke, but a smoker should respect those that don't want to be around it to avoid being exposed to second hand smoking.
