I cannot find it on the net, but I am sure I saw VEGETARIAN rolling papers!
I am sooo happy I can throw my old goat skins away now.
Was always a hassle to scrape the hairs off.
Edit: It is the glue that is vegetarian IIRC
It's likely to be the glue.A friend of mine had some papers that said they were "100% Vegan", we couldn't figure out the how and why of it.
