CTlawyer -“I would not our daughter(s) marry a smoker or former smoker. Who knows what health damage lurks in his body that will surface later.
The fact that the former smoker quit is good, that fact that he ever smoked, with or without parental permission is bad”
I agree. But the main thing to look for in marriage is Middos.
Since people lie all the time, you need Seeatoh D’shmayoh!
Tefilah helps.
