Kodiak here. I don't worry about it. Spit in a bottle.
I used to smoke. Now I dip. Some say the dip is worse than smoking. It probably is.
I can stay on stand all day. When I smoked...it was nearly impossible to go much more than 4 hours before lighting up.
I can't say that I miss the ol' smokers hack.
Nothin' worse than to have a piece of lung-butter dislodge when a decent animal is working in and try to keep that involuntary action of hacking it up from happening!
