there shouldnt be.
i assume you dissolve the pill with water and thats how the coating is left behind, oxymorphone is readily water soluble, so most if not all should be in solution, while a tiny amount (most likely less than .05-.1mg might get stuck
take a paper towel, piece of cloth, just about anything. give the whatever a good lick then "buff" the coating off the pill. just enough to get the coating off, otherwise you start wastin pill. make sure to snort opana and enjoy
DynoSpec, have you ever eaten it? Reason why I am a bit hesistant is bc it kind of looks plasticy mixed with dust bunnies from sitting on my shelf, but it'll get me high, then i would.
i havnt, its got a pretty low oral b/a anyways, and tbh theres probably not much if any oxymorphone there.
as somewhat of a junkie, i just like to get all of my drugs in my system, even the tiny little bits
