First off -
worst possible thread title. You gotta try harder than that, lol.
Regarding the BHT to real heroin - I guess "technically" yes, it can be, but there are a few reasons that it's just not sensible or desirable.
First off, "black tar heroin" really isn't heroin at all (at least it rarely contains heroin). If you're familiar with the
heroin manufacturing process, it consists of taking the raw poppy sap and processing it to extract the morphine, then reacting the morphine with acetic anhydride to acetylate the hydroxyl groups of the morphine at locations 3 and 6.
BTH is apparently what happens if you just skip the morphine extraction process altogether and try to process the raw poppy sap itself. And sometimes they don't even use acetic anhydride, but glacial acetic acid (or even just vinegar).
Some sources say that they started doing this because the United States locked down the sale of Acetic Anhydride and so the cooks tried using GAA or vinegar instead, resulting in the BHT you know of today. But I'm not so sure about this (I mean, come on... they can get the precursors to make methamphetamine and fentanyl, but they can't get their grubby cartel fingers on acetic anhydride? bullshit).
So could you technically take the tar and process it into heroin? Sure. But..... you would have to get
a lot of it since you're basically treating it as the raw sap, and you would have to either extract the morphine and continue with that, or you could extract the monoacetylmorphines and re-acetylate that to get the crude heroin.
But why bother? Even though BHT looks like total shit, some of it is actually pretty good and even
more potent than real heroin. This is because it contains a lot of 6-MAM, which is more potent than heroin
(src):
... and due to the lack of processing and purification, it contains a flurry of other opiates in there that usually get stripped out during the heroin manufacturing process when the morphine is extracted (remember, it's not a bug, it's a feature!). These other opiate alkaloids can result in one hell of a high (enough so to cause an overdose even..)
Here's a thread on Bluelight that you might fine relevant:
Anyone have any experience with pure 6-Monoacetylmorphine?
Hope I answered your question.
