Mad gross I've had to put rolling tobbaco in my peice because i had no more paper gross! and made my piece taste and smell gross.
lol, honestly it's not that bad. i've done it before but in a different way. take a cig and put it where the stem goes. light it and suck. did this on a water bottle bong though. i wouldn't recommend it with a real bong cuz like you said, nasty taste.
