According to an autopsy report from the Los Angeles County Coroner, Adam Rich died in January from an accidental fentanyl overdose.
Rich’s bloodstream also contained so-called non-toxic levels of alcohol and a generic version of Ativan called Lorazepam.
Rich, best known for his starring role in the television drama comedy Eight Is Enough, was 54 years old.
He died on January 8 at his home near Los Angeles. There is no suspicion of foul play.
The series “Eight Is Enough” was about the Bradford family, which consisted of eight children. It chronicled their lives as they dated, grew up, married, and had children of their own. Rich portrayed Nicholas Bradford, the youngest son.
The ABC show, which also starred Dick Van Patten, Lani O’Grady, Connie Needham and Grant Goodeve, ran from 1977 to 1981.
Rich’s other TV appearances have included Code Red, Dungeons & Dragons, Small Wonder, St. Elsewhere and Baywatch.
He was arrested in 1991 for breaking a pharmacy window to get medicine – and was released on bail by his former TV dad Van Patten.
Years of rehab followed, but in 2002 Rich was arrested again for drunk driving after nearly hitting a California Highway Patrol car.
Recent credits include a cameo in the David Spade film Dickie Roberts: Former Child Star and an episode of Reel Comedy in which he played Crocodile Dundee. Both were released in 2003.
