Heroin: What Is It?

Heroin is a highly addictive illegal drug. Millions of addicts around the world are unable to overcome the urge to use it every day—knowing they will face the horrors of withdrawal if they stop.1

Heroin, like opium and morphine, is made from the resin of poppy plants. Milky, sap-like opium is first removed from the poppy pod, then refined to make morphine and further processed into heroin.2

Most heroin is injected, adding risks such as contracting HIV or AIDS, hepatitis B, hepatitis C or other infections in addition to the pain of addiction.3

The Origins of Heroin

Heroin was first manufactured in 1898 by the German pharmaceutical company Bayer. It was originally marketed as a treatment for tuberculosis and a remedy for morphine addiction.4

A Vicious Circle

In the 1850s, opium addiction was a major problem in the United States. The “solution” was to replace opium with a less potent and supposedly nonaddictive substitute—morphine. However, morphine addiction soon became an even bigger issue.5

The next substitute drug was heroin, which turned out to be even more addictive than morphine. With the heroin problem came yet another “nonaddictive” substitute—the drug now known as methadone. First developed in 1937 by German scientists searching for a surgical painkiller, methadone was exported to the US under the trade name Dolophine in 1947. Renamed methadone, the drug was soon being widely used as a treatment for heroin addiction. Unfortunately, it proved to be even more addictive than heroin.76

Today, heroin remains a global problem. In the United States alone, it claims some 20 lives every single day.8
