opioid crisisA public health crisis in the United States and Canada involving a sharp increase in the use of, addiction to, and overdoses from opioid drugs, especially since 2015 (although the trend is traced to the late 1990s). Opioids, typically used as prescription painkillers, include morphine, oxycodone, hydrocodone, and fentanyl, as well as heroin, which is illegal. Ingesting high doses of opioids can cause respiratory failure and death. Also known as the "opioid epidemic." The opioid crisis has led to a staggering number of deaths in a short period of time.See also: crisis, opioidopioid epidemicA public health crisis in the United States and Canada involving a sharp increase in the use of, addiction to, and overdoses from opioid drugs, especially since 2015 (although the trend is traced to the late 1990s).

(1) A drug that has narcotic effects similar to opium (Papaver somniferum) but is not derived from it.
(2) An endogenous peptide (e.g., endorphin) that acts on opioid receptors.opioid Neurology A pain-attenuating peptide that occurs naturally in the brain, which induces analgesia by mimicking endogenous opioids at opioid receptors in the brain. See Opioid-mediated analgesia system.
