Clark County coroner spokeswoman Samantha Charles said after toxicology results were received Monday, “The cause is cocaine intoxication.”
Police have said there was no forced entry and no suspicious circumstances when Dubrow was found dead Nov. 25 at his Las Vegas home. He was 52.
Quiet Riot was perhaps best known for its 1983 cover of “Cum on Feel the Noize.” The song, featuring Dubrow’s powerful, gravelly voice, appeared on the band’s album “Metal Health” – which was the first by a metal band to reach No. 1 on the Billboard chart.
DuBrow recorded a solo album in 2004, “In for the Kill,” and the band’s last studio CD, “Rehab,” came out in October 2006.
