Authorities in the US are panicking to get to grips with the rise of a dangerous new drug dubbed ‘grey death’ that can kill in one hit.
Investigators, who nicknamed the drug, believe that the substance has been the cause of multiple deaths in Alabama, Georgia and Ohio, and are warning other states about the possible dangers.
Grey death is believed to be a combination of several opioids including heroin, fentanyl, carfentanil (a powerful tranquiliser used on elephants) and a synthetic opioid called U-47700.
So called because it looks like concrete mix and can be found in hard lump or in a fine powder, it is said to be dangerous due to the unknown quantities of each drug and additional cutting agents.
