TrendPulse|Cause of death for Adam Harrison, son of 'Pawn Stars' creator Rick Harrison, is released

The TrendPulsecause of death for Adam Harrison, the son of "Pawn Stars" creator and star Rick Harrison, has been released a month after he died in a Las Vegas home.

The 39-year-old died from fentanyl and methamphetamine toxicity, a Clark County, Nevada, public information officer confirmed in an email to USA TODAY Thursday. The manner of death was determined to be accidental, the Clark County Office of the Coroner/Medical Examiner ruled.

A full coroner's report will be released at a later date.

According to a police report by the Las Vegas Metropolitan Police Department, obtained by USA TODAY on Jan. 26, Adam Harrison was pronounced dead in the guest house he was living in on the afternoon of Jan. 19. He was discovered after another resident expressed concern about him not making an appearance since Jan. 17. The landlord found him unresponsive, prompting a call to law enforcement.

Laura Herlovich, a representative for the family, said in a statement to USA TODAY on Jan. 22 that Harrison allegedly died of a fentanyl overdose. In a statement to TMZ published Jan. 22, Rick Harrison said, "The fentanyl crisis in this country must be taken more seriously."

In 2021, 107,000 people died from drug overdoses in the U.S., according to the Centers for Disease Control and Prevention.

Opioids, specifically synthetic opioids like fentanyl, are "the main driver of drug overdose deaths. Nearly 88% of opioid-involved overdose deaths involved synthetic opioids," per the CDC. According to a recent report by the laboratory Millennium Health, illicit fentanyl is increasingly being used in conjunction with other substances, such as methamphetamine.
