I've been dipping for years on stand. never had any negative reactions to the spit itself, but I do believe it probably increases the amount of bacteria in your mouth and increase mouth odor, so yes, I do believe it can effect deer that are down wind. But the chew itself is not alarming to deer IMO.

I keep telling my self I need to quit this year....then next comes......then the next....... It's a horribly addicting habit. I love it!!!! Life without my Twolf would be brutal
