I smoke on the stand.I also spend the whole day on one too.I have to use my head when smoking.I have stands that I WILL NOT smoke on and then I have some that it is ok to.You have to play the wind (most important factor for any hunter)I can recall one time when it was almost too dark I figured I hadnt seen anything in a couple hours got busted when they came from the wrong direction so I lit up.Just to have a doe walk right in.Didnt know what to do with my smoke so I slid it to the side of my mouth and made my shot.Laughed afterwards because I probably looked like a idiot shooting my bow with a smoke hangin out of my mouth.Finished my smoke and got down and gutted her.She fell 4 yards from where I shot her.I have dropped a cig from my stand after putting it out(slippped out of my fingures while opening the lid) and have watched deer go up and smell the but.
