Nah, not really. Sure it might make a non-smoker feel worse while it goes through them, one eaten cigarette isn’t gonna kill an adult.

Now if it was the amount of nicotine out of an entire 20 pack, or someone being stupid enough to suck/chew on a daily nicotine patch, well that would be a different story… 💀

If one does happen to have intestinal worms, well I think eating a cigarette is by far the lesser of the two discomforting evils…
