I don't smoke while bow hunting, more because of motion,but do when gun hunting when the scent/motion game isn't as important. I've shot some nice bucks right after smoking. I do question the idea myself. It all goes downwind. And I don't care how much sent-lock, scent blocker, scent killer, scent free anything, you use,if they're downwind, you're screwed. My wife says I can buy a new ATV if I quit smoking.
