Proper etiquette is to just lay your cigar down when finished and let it t die a natural death. Then empty your ashtray when you are done for the smoking session.

But the beauty is do it however you feel like doing it. There are suggestions that some will call rules, but it’s really all up to you. Especially if your smoking at home. If your at a cigar lounge, do things the proper way to show you have couth and deboner.
