*Ehh* - IDK what's happening to all of the Morphine in my homebakes - when I cook, say 200mg of base M, it's not feeling like 100mg of pharma Diamorphine HCl did. And it doesn't really feel like there's a lot of unreacted M in there, either.
I can only think that a smaller amount of it is being acetylated, and the rest might be turning into some kind of inactive by-product...
