Has anyone here tried nicomorphine? Pretty much unheard of in the US but supposedly somewhat common in central/east Europe?
I'm getting interested in opioid peptides but I doubt those ever show up outside of labs...
Nicomorphine is not a drug of its own, it is a morphine salt. It's real name is morphine dinicotinate. Just like heroin is morphine diacetate. These are morphine ester salts, they aren't "drugs" of their own. Just like there is morphine sulfate, morphine hydrochloride, morphine citrate, etc.
For those claiming "Opium" - that's nothing "rare" or "exotic". Opium is just morphine, codeine, thebaine, and whatever other opium alkaloids. Mostly its morphine though.
As for me, the rarest opiate I have tried is levorphanol orally.
