Someone in another thread pointed out that it was Fentanyl implicated in the death of Prince. I sort of assumed that he was misusing a prescription, but actually it appears that he had fakes in his possession. So one wonders if he got them 'off the street' or were the pharmacists distributing counterfeit products? If it's the second then wow.......
"Medical examiners concluded that musician Prince died on April 21, 2016, from an accidental fentanyl overdose.[60] The drug was among many identified in counterfeit pills recovered from his home, especially some that were mislabeled as Watson 385, a combination of hydrocodone and paracetamol.[60][61]"
