The only thing I have to say about smoking in the stand is, stop & think about what is around you......DRY LEAVES it's also called tender if you are starting a fire. Why is it called that because it lights easy.
One dropped cigarette is all it would take to screw-up everyone hunting in that woods for the rest of the season.
Are you selfish enough to risk that? It really doesn't matter if the deer smell it or not. It is not a good idea!
