Since ya'll are so interested in cigars, (I don't think it's really an issue in this trial though), they, in my experience, are something men do as a "big deal ceremonial" type thing. It's planned in advance, they prepare in a ritualistic way by cutting, rolling it around, licking it, and then lighting it up. This is normally paired with a beverage (as Jason actually said, except WATER?, IDK). Then they puff away...for a L-O-N-G time, like an hour.
It's just not something you go and do as a "quickie" thing, like a cigarette, in a doorway, in the wind, in the cold. No, the circumstances do not meet the cigar-smoking environment criteria, IMO.
But I think he may have smoked a cigar at some point in that decade. If the "guys" did it, he would join in.
ETA: and now after describing that, I have to go barf.
