a real oc 80 should be .270-.279. There ARE fakes going around some places, but only 80's are affected. the fake 80's look more lime green in color, and most importantly the fake oxycontin 80's are GREEN INSIDE. the real ones are just coated green, with the inside powder being white. google-images fake oxycontin. 1000's of pics. Also I've heard from several sources that the fakes have fentanyl in them. so taken orally they would'nt do much, unless you let it dissolve in the cheek (buccal)cavity. (like fentora) then they would probably be real nice, but only last like 20min total; as opposed to the 10min rush, and then several hour high of oxycodone.
