Some Controlled Substances - Heroin

Whenever one thinks about drugs of abuse and addiction, heroin is one of the most recognized drugs. Heroin is a synthetic drug, produced from the morphine contained in the sap of the opium poppy. The abuse of this particular controlled substance has been known for many years. The correct chemical nomenclature for heroin is O3, O6 -diacetylmorphine.

Heroin is synthesized from morphine in a relatively simple process. The first synthesis of diacetylmorphine reported in the literature was in 1875 by two English chemists, G.H. Beckett and C.P. Alder Wright. 1 In 1898 in Eberfield, Germany, the Farbenfarbriken vorm Friedrich Bayer and Company produced the drug commercially. An employee of the company, H. Dresser, named the morphine product “Heroin”.2 There is no definitive documentation as to where the name “heroin” originated. However, it probably had its origin in the “heroic remedies” class of drugs of the day.

Heroin was used in place of codeine and morphine for patients suffering from lung diseases such as tuberculosis. Additionally, the Bayer Company advertised heroin as a cure for morphine addiction. The analgesic properties of the drug were very effective. However, the addictive properties were quite devastating.

In 1924, Congress amended the Narcotic Drug Import and Export Act to prohibit the importation of opium for the manufacture of heroin. However, stockpiles were still available and could be legally prescribed by physicians. The 1925 International Opium Convention imposed drug controls that began to limit the supply of heroin from Europe. Shortly thereafter, the clandestine manufacture of heroin was reported in China.

The supplies of opium in the Far East provided a ready source of morphine—the starting material for the synthesis. The medical use of heroin in the U.S. was not banned until July 19, 1956 with the passage of Public Law 728, which required all inventories to be surrendered to the federal government by November 19, 1956.
