1. Heroin

   Heroin, also known as diamorphine, and colloquially as H, smack, horse, brown, black, tar, and other names, is an opioid analgesic synthesized by C.R. Alder Wright in 1874 by adding two acetyl groups to the molecule morphine, found in the opium poppy. It is the 3,6-diacetyl ester of morphine. Heroin itself is an active drug, but it is also converted into morphine in the body. When used in medicine it is typically used to treat severe pain, such as that resulting from a heart attack or a severe injury. The name "heroin" is only used when being discussed in its illegal form. When it is used in a medical environment, it is referred to as diamorphine. The white crystalline form considered "pure heroin" is usually the hydrochloride salt, diacetylmorphine hydrochloride. Illicit heroin is sometimes available in freebase form, dulling the sheen and consistency to a matte-white powder. Because of its lower boiling point, the freebase form of heroin is also smokable. It is prevalent in heroin coming from Afghanistan, which as of 2004 produced roughly 87% of the world supply in illicit raw opium. However, production in Mexico has risen six times from 2007 to 2011, changing that percentage and placing Mexico as the second largest opium producer in the world.
