What is Heroin?

Heroin is a very addictive chemical called diacetylmorphine. Heroin is a modified form of morphine, a highly abundant opium derived from the seedpods of the poppy plant.

Appearance and route of administration of heroin

Heroin is most commonly sold as a white or off-white powder. The color changes from pure white as the level of impurity in the chemical rises. In some areas, heroin is also available as a sticky dark brown or black substance.

Heroin can be taken via several different administration routes and can be injected, snorted or smoked.

Epidemiology of heroin abuse

Data from the National Household Survey on Drug Abuse estimates that nearly 3 million U.S. residents aged 12 and older have used heroin at least once in their lifetime. Initially, school aged children and young adults commonly smoke or snort the drug, under the impression that this is less addictive. In most cases, these individuals move onto using the injectable form of heroin at a later stage.
