The Tennessee Bureau of Investigation shared concerns Monday over deadly drug mixtures submitted as evidence in recent drug cases. According to the TBI, forensic scientists have found samples containing lethal drug combinations that agents worry are being sold in Tennessee. TBI said the toxic mixtures have rarely, if ever, been seen in TBI evidence submissions. One sample contained a combination of ketamine, tramadol, cocaine, heroin and fentanyl. Another drug mixture contained a mixture of methamphetamine, acrylfentanyl and methoxyacetylfentanyl.

These are combinations of drugs that don’t even make sense, and they are combinations that are lethal,” said T.J. Jordan, assistant director of the TBI’s Drug Investigation Division. “It’s the latest example of why no illicit street drug is safe. And with combinations of these extremely toxic drugs being mixed with each other, it’s a cocktail that has us very concerned. We need to remind the public again that these already-dangerous drugs are becoming more and more deadly.”

This comes after TBI partnered with local law enforcement to warn neighbors about finding fentanyl in samples of heroin, cocaine and pills made to resemble prescription opioids. TBI said anyone struggling with drug addiction issues should call the Tennessee REDLINE at 1-800-889-9789.
