Like most of us, I hardly know any smokers any more (good thing obvs) and no one who smokes in the house.
I see a couple of blokes who live in houses opposite me who smoke outside their front doors (bit odd as they've got gardens) and if I or any of my occasional smoker friends want a cigarette we always go outside.
I've worked as a weekend Estate Agents showing houses and can only think of one house I've been in since the mid 2000s that actually reeked of cigarettes. It was a nice family house, I felt sorry for the kids who lived there.
