What can happen from smoking newspaper?

I know its stupid but i was just messing around and decided to make a fake blunt out of the yellow pages that was lying around. Its got colored adverts and black ink on yellow paper. I just held it in my mouth and blew out for multiple fake blunts and accidentally inhaled twice causing a bad cough. i did this for a while cause it was pretty fun and went about my day. Now im flipping out with anxiety thinking im dying or got cancer or something. I know it was stupid i just need some reassurance that i dont have ink poisoning or anything. I only inhaled twice... thanks
