Juice WRLD’s cause of death has been revealed.

The Cook County Medical Examiner says the 21-year-old rapper, whose legal name was Jarad Anthony Higgins, died from an accidental overdose after toxic levels of oxycodone and codeine were found in his system.

“Higgins died as a result of oxycodone and codeine toxicity,” tweeted the Cook County Medical Examiner. “The manner of death is accident.”

Juice WRLD died last month after suffering a seizure and going into cardiac arrest after landing at Chicago’s Midway Airport. According to TMZ, he swallowed several Percocet pills in an attempt to hide them from the feds.

The feds seized 70 pounds of weed in vacuum-sealed bags that were stashed inside suitcases in the private jet, along with three registered guns. Two of Juice’s associates were arrested for gun possession.

Juice WRLD was open about his struggles with drug addiction. Last year, he tweeted that he was done with codeine. “Bae I’m sorry I be tweaking, you’ve put up with more than ppl know I know I be scaring you, fuck Codeine I’m done,” he told his girlfriend Ally Lotti. “I love you and im letting it be known publicly that ain’t shit fucking up the real love I found. Learn from this everyone. Addiction kills all but you can overcome.”

His music lives on. Last week, Eminem released his new album Music To Be Murdered By featuring a collaboration with Juice WRLD called “Godzilla.”
