I smoke while on stand and I can honestly say the only times, which have been few, that I've been busted was because of movement. No other reason! Nobody can tell me that a deer knows the differance between cigg. smoke and smoke from someonesnearby chimney. I always keep my camo in zipp locksto keep them oder free so I do'nt smell. When I do smoke, it simply rises then disapates without a problem.
