I' m an ex-smoker and I' ve smoked in my stand a lot. And I never had any problems tagging out even on state land, which s where I usually hunt. I' ve put cigarettes out in order to draw the bow. You could smoke a box of cigars and it wouldn' t matter a bit as long as you' ve got your stand downwind. By the way, cigarette smoke is a great for determining wind direction. ;o)

But I' m glad I don' t smoke any more. When smoking, scent control is limited to staying downwind. I don' t think all the scent eliminator, carbon spray, carbon scent control suits, cover scents, etc.... can negate the overwhelmingly strong and persistent scent of stale tobacco smoke and smoker' s breath.
