What happens if you eat cigarette ash?

unless you ate about a litre of it I doubt you would be too sick. I guess It depends.

this is true I've had quite a few experiences accidently eating or drinking ash. Drinking isn't so bad it sinks and you find it at the bottom. Eating it to really isn't so bad you usually get a stomach ache after about a half a smoke's worth ( funny funny story on that one)
