It was determined that the rapper died from a mix of fentanyl, cocaine and ethanol (alcohol) in his system.
Malcolm James McCormick, the chart-topping rapper known as Mac Miller, had fentanyl, cocaine and ethanol in his system at the time of death on September 7, according to Los Angeles County's Department of Medical Examiner-Coroner.
McCormick, born January 19, 1992, "was discovered unresponsive in his home located in the 11600 block of Valleycrest Drive in Studio City", the department writes in the announcement of its findings.
Emergency services were called to the scene and declared the rapper dead shortly after. While used to treat severe pain, like that experienced by cancer patients, illegally made fentanyl is often mixed with heroin or cocaine, according to the Centers for Disease Control and Prevention. After an autopsy, the Los Angeles coroner ruled his death accidental.
The report described the substances found in Miller's apartment at the time of his death. There were 2 small bags found with the white powder. "On a separate table along the north wall of the studio room, an ipad was noted with linear white powdery residue".More news: OnePlus pulls another first with 6T's new gradient colour
An empty bottle of alcohol was found on the nightstand and a bottle of prescription pills was found in the bathroom.
Unfortunately, McCormick struggled with staying sober, frequently slipping into excessive substance abuse. The Los Angeles police officials had quickly determined that there were no signs of foul play and turned the investigation over to coroner's officials.
Miller had spoken openly of his drug addiction in interviews and in his music, and dated Grande, 25, for about two years before the couple split earlier this year.
"I used to rap super openly about really dark" things, Miller told Vulture, "because that's what I was experiencing at the time. It should be all the emotions".
