RE: Stopped smoking will it make a difference?
Hell with the deer - keep to it and so much of you life will get better - you just don't know how bad you feel when you are smoking. I was a 2+ pack a days for18 years and I have not had a smoke for 12 years now.
As far asaffect ondeer - I think it depends on the area you hunt and how sensitive your deer are toodd scents. In my woods you will keep them away with tic-tac, in your pocket.
