This question comes up fairly often and I reply each time. I smoke while on stand, like someone said earlier, not like I would if I weren't hunting though. I take deer every year. Three, so far this year. A 6pt non-typical in Pa, an8pt from Albertawith my compound, and a doe with my CB also in Pa.I had a MONSTER 10pt B&C buck inside of 20yrds in Alberta but no shot opp. That's for the folks that say you'll never have a MATURE buck come in close if you smoke while on stand! Not bragging, just the facts.
Anyway, I don't condone smoking on stand [:@]but I must say I believe it's the movements associated with smoking rather than the smoke itself that gets hunters busted. Also, as I've said in the past, I don't believe deer know the diff between cigg smoke and that of someones fireplace. I don't think they (deer)associate it with humans either, unless they actually see it coming from one.
These are strictly my thoughts,experiances andobservations. Obviously open for debate, it always is.
