I would find out before. I can’t stand smokers!! And it’s gonna eventually kill him or give him lung sicknesses….. I wouldn’t take the chance. If he smokes, he’s showing he doesn’t take life seriously. Why would I want to marry someone who doesn’t value life?!?!?!!?
I know that nowadays all the bachurim smoke, but I would make sure the guy who I marry will NOT be one of those guys!!!
