A fatal new drug combination of heroin cut with synthetic fentanyl has emerged that may be too dangerous to even touch, a police department in Louisiana is warning the public, according to CBS News.

A spokesperson for the St. Mary's Parish Sheriff's Office in southern Louisiana told CBS affiliate KLFY-TV that the substance looks like "chunks of concrete." It can also be found in powder form. In addition to heroin and fentanyl, the substance may also include carfentanil, an opioid analgesic and a tranquilizing drug, and U-47700, another synthetic opioid.

Nicknamed 'gray death,' the substance can be injected, swallowed, smoked or snorted. It first appeared in Georgia and Alabama in 2017 and also has been found in Ohio and Pennsylvania.

According to, gray death "can be extremely toxic, even in the smallest quantities, which could rapidly lead to fatal respiratory depression."

It can be absorbed through the skin and should only be handled with protective gloves.
