Metonitazene is classified as a novel opioid but is dissimilar from fentanyl and U-series analogues. Novel opioids have been reported to cause psychoactive effects similar to heroin, fentanyl, and other opioids. Novel opioids have also caused adverse events, including deaths, as described in the literature. Structurally similar compounds to metonitazene include etonitazene, isotonitazene, and clonitazene. These synthetic opioids were first synthesized and reported in the literature in the 1950s.
