Heroin (also called Diamacetylmorphine or Diamorphine) is a natural opioid. It is an analgesic (a painkiller). It is made from the sap of the poppy plant. It is like other drugs made from the poppy plant sap, for example, opium or morphine. There is a high risk of getting addicted. Many countries consider it to be an illegal drug unless it its taken for medical purposes.

Heroin is a white or brown powder. People smoke or inject heroin to get a calm feeling of relaxation called "being high." Heroin is a very addictive drug. This means that once a person starts taking heroin, they will want to take more heroin, even if it's making them sick.
