Prescott Valley Police say a recent overdose turned up the first very dangerous drug of its kind in the town. The drug known as “Gray Death” is an illicit opioid combination of powerful and dangerous drugs that have led to several fatal overdoses in the United States. The combo drug is said to be many more times potent than heroin. Overdoses and confiscation of the chemicals have been reported in Alabama, Georgia, Florida, Indiana, Pennsylvania and Ohio. According to the National Institute on Drug Abuse “Gray Death” isn’t a single drug, but typically contains several potent opioids, including whatever a drug dealer has on hand. It could contain heroin, fentanyl, and U-47700, all extremely potent narcotics.
