^ that's what I always assumed, never dared try it.
Papers are gonna be made primarily from cellulose, so it digests fully and won't have any negative effect. It is, after all, designed for ingestion via smoking, so it's not like there's gonna be poison in the glue or anything like that.
That, and cellulose is found in probably half the food in your house. Much easier to swallow than TP too and papers aren't even expensive if you're not a broke 14 year old.
^ haha i make a cone too and stick it together and twist the top. When I can be bothered. Actually, mostly I just screw up and eat it, it's only if you want to save them that I glue 'em up into little cones...
I always imagined toilet paper would just dissolve in your mouth too.. seems to be a UK/US thing!
