I occasionally smoke cigars because it tastes good. It's like good coffee in smokable form, there's a relaxing sort of process to it and a large variety of flavors to enjoy.
I don't smoke cigarettes because they don't taste as good and I suspect with the increased convenience factor I'd get addicted pretty quickly. I was at one point smoking weed almost every day even though I didn't necessarily want to, just because I enjoyed the ritual of going outside for a smoke at night.
