Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - The term opioid refers to all compounds with opium-like activity. Heroin is made from morphine and is usually sold as a white powder; however, the color may vary to dark brown. “Black tar” heroin may be sticky like roofing tar or hard like coal and is usually dark brown to black in color. Diversion and abuse of opioids is a common practice that is resulting in an increased number of opioid deaths. Opioid-dependent patients may use alternative supplements like kratom to reduce opioid withdrawal symptoms.
