I smoke a cigar after i hunt. I won't take a chance, but here is what I've been told. The smell of smoke is not really alarming to deer, it may even provoke some curiosity,however the smell of a human is an entirely diferent thing . The pheromones produced by your body scream PREDATOR, and that is what alarms them. Like I said I don't smoke on stand but do know people who consistantly kill deer and do smoke on stand.
