Heroin

Heroin, or diacetylmorphine (INN), also known as diamorphine (BAN), is a semi-synthetic opioid drug synthesized from morphine, a derivative of the opium poppy. It is the 3,6-diacetyl ester of morphine (di (two)-acetyl-morphine). The white crystalline form is commonly the hydrochloride salt diacetylmorphine hydrochloride, though often adulterated thus dulling the sheen and consistency from that to a matte white powder, which heroin freebase typically is. 90% of Heroin is said to be produced in Afghanistan.

As with other opioids, heroin is used as both an analgesic and a recreational drug, and has a high potential for abuse. Frequent and regular administration is associated with tolerance and physical dependence, which may develop into addiction.
