Three months since the unexpected death of singer-songwriter Justin Townes Earle, his cause of death has been revealed.

A report from the Tennessee Department of Health revealed on Tuesday (Dec. 1) that Earle died of an accidental “acute combined drug toxicity,” according to Rolling Stone.

His team also shared the update on Facebook, writing “Next to alcohol and cocaine the autopsy report revealed traces of fentanyl indicating that that usage of fentanyl laced cocaine resulted in an overdose.”

“Even though Justin was very outspoken and concerned about the opioid epidemic and the dangers of the ‘legal’ drugs fed by the pharmaceutical companies, he became the victim of a deadly dose of fentanyl,” the post continued. “Illicit drugs laced with fentanyl are causing an enormous rise in overdoses, turning cocaine usage into an even deadlier habit. It only takes a few salt sized granules of fentanyl to cause an overdose. And in most cases, happens so fast that intervention likely could not reverse it.”

“Addiction is a disease and there are many avenues and treatments to become and stay free from alcohol and drug usage,” the post concluded with a message to those who are struggling. “If you or a loved one are struggling with substance addiction please know that you’re not alone and reach out for help. Don’t lose hope.”

You will be missed dearly Justin.”
