I know you guys don' t want to hear this but just quit and you won' t have to worry about it. After 22 + years of smoking and I don' t mean that candy a$$ pack a day stuff I finally quit and its been 6 + years now. Funny when I was smoking I only got 1 deer in alot of years of hunting now if I don' t get 2 or more I consider it a bad year. It your choice and your money. And hey don' t you want to teach your granchildren to hunt?
