I've quit in the past 5 year but I would always get in my tree stand and light up, called it checking the wind...If you are hunting where the smoke is going to the deer, you aren't set up right...I've killed them with a butt in my mouth...

I even remember killing one buck, lighting up a smoke to celebrate and having another come in, I killed him too!!!

I did carry 35mm film canisters for the ashes and butts, but smoking never kept me from killing deer...
