In some countries, like the UK, its pharmaceutical form (diamorphine) is used under strict hospital supervision for severe pain, such as during heart attacks or for terminal cancer patients. In the US, it is a Schedule I drug with no approved medical use.
Chemically, diacetylmorphine has two acetyl groups attached to the morphine molecule. This makes it more lipid-soluble, allowing it to enter the brain more rapidly, where it is then metabolized back into morphine. This results in a more intense and faster-onset euphoric effect, contributing to its higher addiction potential.
