I hardly ever put out a cigar before I finish it. Only once did I re-light a cigar I'd already put out and wasn't impressed with the taste. Usually, if I know I only have time for a quick smoke (like on break from work), I'll have a cigarette. That's rarely a problem in the summer, but when classes start again it could become one since I don't want to be smoking cigarettes between classes, but at the same time don't want to ruin a good cigar by only smoking part of it and then putting it out to go to my next class.

As for extinguishing the cigars, I learned quickly not to squash them out in the ashtray or they stink like hell and my roommate bitches me out...lol. Now, I always just let the cigar burn out when I'm done with it.
