RE: SMOKING and PEEING out of your stand does NOT affect your hunt!!!
IMO it all depends on the area. In some places, smoking and spitting and pissing will run a mature buck halfway across the county. In other places, their use to human smells. Now im not saying they wont take off if they get directly down wind of you, but i doubt a buck in my area will get spooked from smelling my cough matter a day after i was there. I see bucks all the time in places that i was standing less than a day before. Ive only been bowhunting 2 years and i try my best to remain scent free and watch the wind but in the end the deer end up seeing or hearing me before they smell me.
