Is it normal to share a cigar?
Mostly.Normal for most people
Yes, people sometimes pass a cigar around socially, though plenty of people would rather have their own. Since it means sharing something that’s been in someone’s mouth, it’s also completely reasonable to decline.
It’s a thing in some social settings, especially among people who enjoy cigars, but it isn’t a universal custom. Whether it feels friendly or a little gross is mostly personal preference and depends on the group.
Passing one around means sharing the mouthpiece, so germs can travel that way. You can just say, “I’m good, thanks,” or ask for your own—and remember that cigar smoke affects people nearby, too.
