Heroin Introduction Heroin is a derivative of morphine synthesized by a simple aceylation reaction of the parent compound in a manner almost identically to aspirin. It was originally intended to wean morphine addicts from the drug, but has since become a much bigger problem than morphine. The name is derived from "a hero" for it's supposed effect of saving morphine addicts. Heroin is an illegal opiate drug made from the seeds of the opium poppy, Papaver somniferum. The opium poppy is a plant found in the Middle East, Southeast Asia and parts of Central and South America. To harvest opium, the seed pod of the poppy is cut and a juice flows out. The main ingredient that is extracted from raw opium is morphine. Morphine is easily converted to heroin by a chemical process.Currently, heroin has no real medicinal value and is one of the most abused narcotics ever synthesized, being responsible for the destruction of many lives. Heroin addiction is also associated with a high risk of AIDS, due to sharing of needles used to inject solutions of the drug.
