I will often smoke my clothes as I hunt (just did it today) and it seems that the more I do it, the closer I get to critters on the ground. Last year, about 2 or 3 hrs. after intentionally smoking my clothes, I called in a bear and shot it (with a compound) at 3 yds. It never smelled me-at 3 yds. I have had deer down wind of me after smoking my clothes from 5-20 yds. multiple times. I know they smell something because their nose goes up and they are probably smelling the smoke, but they didn't spook if I stayed still. Here's my theory: Since smoke is made of carbon, I think the carbon absorbs human odors while also acting as a cover scent (wood smoke smell) that is not threatening to animals.
