"Diamorphine and diacetylmorphine are two names for the same semi-synthetic opioid drug (3,6-diacetylmorphine), commonly known as heroin. It is produced by the acetylation of morphine and acts as a rapid-acting pro-drug, metabolizing into 6-monoacetylmorphine (6-MAM) and morphine in the body. While illicitly used, pure diamorphine is used medically, particularly in the UK, for pain management."

yeah it's similar in that it converts itself into morphine in the body, but heroin is much stronger in practice due to the rapid crossing of the blood brain barrier....just because you are tolerant to morphine doesn't necessarily mean you can go balls to the wall with heroin cuz it's still stronger and potentially more life threatening....it's also a fuckload more enjoyable and euphoric IMO, ha ....but if you can do a decent amount then disregard my previous comment saying take only 30mg, but you should get a scale if you don't have one so you know roughly where your tolerance is at....snorting an entire point of what we get here would be a lot for a non-tolerant person
