As was previously suspected, Miller's death was confirmed to be a result of an accidental overdose. The L.A. County Coroner's Office results of Miller’s autopsy and toxicology report were announced Monday, TMZ reported. According to the report, Miller died from "mixed drug toxicity": specifically, a lethal mix of fentanyl, cocaine, and alcohol, the coroner determined.
The report also noted that although the individual quantities of the drugs consumed were not necessarily a lethal amount, it was the combination that proved fatal. Fentanyl is an opioid 30 times more powerful than heroin, and has suddenly become the new substance driving the opioid epidemic. Miller isn't the only one to fall prey to the drug.
