Gray death

Slang term for opioid drug mixtures

Gray death is a slang term which refers to the dangers that emerged in 2017, when potent mixtures of synthetic opioids, for example benzimidazole opioids or fentanyl analogues, were often sold on the street misleadingly as "heroin". However, other substances such as cocaine have also been laced with opioids that resulted in illness and death.
