Heroin is an opioid drug that is synthesized from morphine, a naturally occurring substance extracted from the seed pod of the Asian opium poppy plant. Heroin usually appears as a white or brown powder or as a black sticky substance, known as black tar heroin.

Heroin is also known by names like junk, smack or simply H. Street heroin is often combined with dangerous additives like morphine or the powerful pain reliever fentanyl.
