My Dad too has emphazema, he has smoked since he was a teen, he's 81 now. Dad switched from cigarettes to a pipe following a doctors suggestion about 30 years ago. All he wants to do now is sit and smoke. Mom will not allow him to smoke in the house, so Dad sits out on the patio yearround smoking. Mom lives inside the house, Dad lives on the patio. Dad has damentia, and can not stay focused on anything, except smoking his pipe. Mom will send him out to sweep the patio. Dad will start then next thing she sees, is him sitting and puffing on his pipe. I have talked to Dad about his smoking before. He says it is something he enjoys, and he just has to do it when the urge hits. He's addeicted, and at 81, I don't see him quiting. Dad is not on Oxygen yet but it is coming.
Two of my brothers smoke and will not talk about quiting.
