I am not sure it may depend on the type of fish. I am not a smoker but do chew snoose. When I was 11 I went fishing in a small lake east of auburn lake moneysmith. We were fishing for catfish and perch. We had probably caught about 100 fish when my friends dad threw his butt in the water and a catfish came up and ate it. I scrounged up a butt from the bottom of the boat and put it on my hook and proceeded to catch fish after fish it worked just as good as the worms we had been using. Who would of figured that.
