Mac Miller Official Autopsy Report Findings

The Los Angeles County Coroner concluded the death was an accident, listing multiple drug intoxication as the primary cause. Fentanyl, a potent synthetic opioid, was the drug most directly responsible for the fatal respiratory depression.

Toxicology tests showed a combination of cocaine, alcohol, diazepam, and other substances in his system, which together increased the risk of severe respiratory suppression. No evidence of homicide or foul play was identified.

Timeline of Events on September 7, 2018

On the day of the incident, Mac Miller was staying at a friend’s home in the San Fernando Valley. Around midday, he was found unresponsive by companions and emergency services were called. Despite onsite medical aid and transport to a nearby hospital, he was pronounced dead shortly after arrival.

Investigators later determined he had consumed a dangerous mix of drugs earlier that day. The timeline reconstructed by authorities showed a pattern of escalating drug use leading to the acute overdose.

Toxicology and Drug Mix Analysis

The final toxicology report highlighted fentanyl as the critical agent, present in both prescription patches and illicit forms. Cocaine and alcohol acted as central nervous system stimulants and depressants, respectively, compounding the physiological strain.

Additional medications, including diazepam, were found in levels consistent with non-medical use. This polypharmacy created a synergistic effect that suppressed breathing and heart function to lethal degrees.
