First off, this home could be reported to the licensing board for a resident's rights violation.
Secondly, MOST sane homes have designated smoke areas, times and staff supervision. The residents are allowed to smoke, but within these parameters. The biggest concern isn't the 'smoke' killing them but burns and fires.
Another horrifying scenario! Especially in the cold winter.......they will try to sneak a cigarette rather then go outside far from the building. And most of them are on meds, and smoking on meds alone just isn't a good combination.
The nursing home, with compassion, should have a day room for their patients or residents who smoke. And a staff member can be in the day room with patients when they smoke. It's a win win for everyone.
