Yes, I have, on occasion. I was gifted several really primo super premiums, along with several other good smokes. Since I received duplicates of the super premiums, I passed one along to a deserving brother who had never had one.
On other times I have passed along very nice cigars I had received as gifts that just didn't meet my taste profile, to someone who loved them. And I sent even better sticks to the one who had gifted me in the first place.
Gifts are always special, but too special to let sit if I won't be smoking them. I agree with Andy, once you have received a gift, it belongs to you, to do with what you wish.
If I give something nice to someone, and it's something they don't particularly enjoy, I'd be happy for them to trade it for something they like.
