Never done it but i was lookin into it and wondering if i let the water with the opiate in it evaporate would i be left with an insufflatable powder of hydrocodone?
Yes it will be insufflatable, and assuming you started out with a fair number of pills I would just go ahead and do the extraction one more time if you want to get even more acetaminophen out of it. Just depends on how much product you started with. 5 pills once is fine. 50 pills... a few times more would not hurt. And remember acetaminophen Burns!
