In the 1980' s I did alot of camping and hunting, every weekend the entire season. We had the fire every night and it stunk up my clothes. I used ground blinds exclusely and had deer walk all over me. My scent didn' t seem to bother them at all. Whether that forms a hypothesis about smoke scent can be debated because they were use to our camp and our smoke.
There' s a guy that teaches a class on how to learn to get close enough to touch deer in the wild. We' ve discussed this in this forum last year or year before. His primary cover was dirt and mud if I remember right. He would cover his whole body in mud. His secondary cover if mud wasn' t available was wood smoke.
