heroin meaning

EN[ˈhɛr oʊ ɪn] [-ɪn]
  • Heroin /ˈhɛroʊɪn/ (diacetylmorphine or morphine diacetate, also known as diamorphine (BAN, INN)) and commonly known by its street names of H, smack, boy, horse, brown, black, tar, and others is an opioid analgesic originally synthesized by C.R.
  • Illicit heroin is sometimes available in freebase form, dulling the sheen and consistency to a matte-white powder. Because of its lower boiling point, the freebase form of heroin is also smokable.
  • As with other opioids, diacetylmorphine is used as both a legal, medically prescribed drug (e.g., as an analgesic, cough suppressant and as an anti-diarrhea drug) and a recreational drug, in which case the user is seeking euphoria.
