I think it may help by leaving behind no human scent from your clothes if you rub some brush on the way to your stand.
I couple smoking my clothes with stepping in a puddle or mudding up my boots on the way into my stand. Using that method, I have seen many deer follow my trail with zero clue or alertness to my presence.
Smoke = carbon I think, right? Carbon is what they put in all those expensive suits. So.......
One issue:
If a deer gets downwind, you are usually out of buisness no matter what you try. Play the wind AND try to leave no scent trail into your stand.
