I don't think smoke alarms deer at any rate. Several years ago, my cousin and I were hunting in a timber together. His stand was about 150 yards upwind of mine. It was getting late in the day and I suddenly smelled cigarette smoke. Moments later I saw four deer walking through the timber toward my cousin. My first thought was, "Crap! Frank's going to get busted because of the smoke smell." They were out of range for me, so I just waited to see what would happen. About five minutes went by and my cell phone began to buzz. It was Frank, "Hey, I just shot a big doe, so you'd better wait a few minutes before you get down." His stand was between me and the truck.
Obviously, if I could smell the smoke, the deer did, but he shot that doe about 12 yards from his tree and she was directly downwind. He had to put out his cigarette and pick up his bow to shoot her.
I have read that Indians (or to be politically correct, Native Americans) used smoke as a cover scent as well. With the equipment they had, they definitely had to get close. I think I may give it a try this fall, especially when I plan to hunt from the ground.
