Although it was a fentanyl overdose that killed Prince April 21, the medical examiner said it was part of a deadly chemical cocktail.
A source close to the investigation says U47700
was part of the mixture. The potent painkiller is a synthetic opioid, eight times stronger than morphine.
Investigative sources told reporter Beth McDonough that Prince may have thought he was taking a legitimate painkiller, like hydrocodone or fentanyl, that unknowingly also had U-47700 in it.
The pills often look just like other medications. Plus, U47700 can be resistent to the life-saving antidote Narcan.
Because U-47700 is not considered a controlled substance by state or federal agents, it's not regulated. The Drug Enforcement Administrations says it tends to be produced overseas in China or Eastern Europe. It's widely available, easily accessible and affordable, about $40 online.
