Could be dangerous
Most paper contains traces of dioxin, a byproduct of bleaching with chlorine.
Dioxin is a carcinogen
and an extremely toxic chemical. It is not considered hazardous to touch these products, but it is possible that if you "eat paper" even without swallowing that some of the dioxins will be absorbed into your body. I would not take this chance. Unbleached paper is relatively safe. See comment:.
