"The Goldbergs" actor Jackson Odell died from an overdose in a sober living facility where he sought treatment, according to the Los Angeles County Medical Examiner.
It was earlier reported that Odell, 20, was found unresponsive at his Tarzana, California, home on June 8.
According to USA Today, the coroner's report ruled the actor's death an accident resulting from "acute heroin and cocaine toxicity".
The toxicology report confirmed speculation that narcotics were involved.
Odell "had a history of heroin addiction," Ed Winter, assistant chief of investigations at the coroner's office, told the publication.
The musician-actor was best known for his role as Ari Caldwell on ABC's "The Goldbergs" from 2013 to 2015. He also starred briefly on "Modern Family".
Odell died a month before turning 21.
