About Heroin
Heroin, or diacetylmorphine , also known as diamorphine , is a semi-synthetic opioid drug synthesized from morphine, a derivative of the opium poppy. It is the 3,6-diacetyl ester of 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. Frequent and regular administration is associated with tolerance and physical dependence, which may develop into addiction.
Internationally, heroin is controlled under Schedules I and IV of the Single Convention on Narcotic Drugs. It is illegal to manufacture, possess, or sell diacetylmorphine without a license in Belgium, Denmark, Germany, Iran, India, the Netherlands, the United States, Australia, Canada, Ireland, Pakistan, the United Kingdom and Swaziland.
Under the name diamorphine, it is a legally prescribed controlled drug in the United Kingdom. It is available for prescription to long-term users in the Netherlands, United Kingdom, Switzerland, Germany and Denmark alongside psycho-social care, and a similar programme is being campaigned for by liberal political parties in Norway. Some countries allow the government to sell or donate high-quality seizures of drugs and precursors which are otherwise legal for medicinal use to pharmaceutical manufacturers for use in preparing licit supplies of medical drugs and research chemicals; this was the case in Croatia prior to 2007.
The German drug company Bayer named its new over the counter drug "Heroin" in 1895. The name was derived from the German word "heroisch" due to its perceived "heroic" effects upon a user. It was chiefly developed as a morphine substitute for cough suppressants that did not have morphine's addictive side-effects. Morphine at the time was a popular recreational drug, and Bayer wished to find a similar but non-addictive substitute to market. However, contrary to Bayer's advertising as a "non-addictive morphine substitute," heroin would soon have one of the highest rates of dependence amongst its users.
The opium poppy was cultivated in lower Mesopotamia as long ago as 3400 BCE. The chemical analysis of opium in the 19th century revealed that most of its activity could be ascribed to two alkaloids, codeine and morphine.
Diacetylmorphine was first synthesized in 1874 by C. R. Alder Wright, an English chemist working at St. Mary's Hospital Medical School in London. He had been experimenting with combining morphine with various acids. He boiled anhydrous morphine alkaloid with acetic anhydride for several hours and produced a more potent, acetylated form of morphine, now called diacetylmorphine. The compound was sent to F. M. Pierce of Owens College in Manchester for analysis. Pierce told Wright:
Wright's invention did not lead to any further developments, and diacetylmorphine only became popular after it was independently re-synthesized 23 years later by another chemist, Felix Hoffmann. Hoffmann, working at the Aktiengesellschaft Farbenfabriken in Elberfeld, Germany, was instructed by his supervisor Heinrich Dreser to acetylate morphine with the objective of producing codeine, a constituent of the opium poppy, pharmacologically similar to morphine but less potent and less addictive. Instead the experiment produced an acetylated form of morphine one and a half to two times more potent than morphine itself.
From 1898 through to 1910 diacetylmorphine was marketed under the trade name Heroin as a non-addictive morphine substitute and cough suppressant. Bayer marketed the drug as a cure for morphine addiction before it was discovered that it rapidly metabolizes into morphine. As such, heroin is essentially a quicker acting form of morphine. The company was embarrassed by the new finding, which became a historic blunder for Bayer.
In the U.S.A. the Harrison Narcotics Tax Act was passed in 1914 to control the sale and distribution of "heroin" and other opioids, which allowed the drug to be prescribed and sold for medical purposes. In 1924 the United States Congress banned its sale, importation or manufacture. It is now a Schedule I substance, which makes it illegal for non-medical use in signatory nations of the Single Convention on Narcotic Drugs treaty, including the United States.
