About: Acetylpropionylmorphine

Acetylpropionylmorphine is an opiate analogue that is an ester of morphine. It was developed in the early 1900s after first being synthesised in Great Britain in 1875 but shelved along with heroin and various other esters of morphine. Acetylpropionylmorphone was never used medically, instead being widely sold as one of the first "designer drugs" for around five years following the introduction of the first international restrictions on the sale of heroin in 1925. It is described as being virtually identical to heroin and morphine in its effects, and consequently was itself banned internationally in 1930 by the Health Committee of the League of Nations, in order to prevent its sale as an unscheduled alternative to heroin.
