U.S health officials have issued warnings over the increasing incidence of heroin spiked with elephant tranquilizer. The tranquilizer, carfentanil is a powerful opioid and is said to be one hundred times stronger than morphine.
Carfentanil is so powerful, it can knock out an adult elephant and drug dealers are now cutting heroin with the drug to stretch their supply.
Officials are now warning drug users, many of whom are not even aware that heroin is now being cut with the highly potent opioid. Authorities have reported a spike in heroin overdoses, with 36 reports of overdoses and two deaths.
