lkwdfellow- my father and brothers have asthma so they don’t smoke. and my brothers in law each have family members who died from smoking so they didn’t. Anyway they are married and told their wives that they never had a period in their lives where they smoked. Maybe they smoked once or twice on purim or something but they didn’t smoke as an addiction. YES IT IS POSSIBLE.
As Kapusta said you can find out these things.
