Pawn Stars‘ Rick Harrison reflected on losing his son Adam Harrison to an accidental fentanyl overdose and revealed that he’s still “second-guessing” everything 14 months after his death.

“I think about him every day,” Rick, 59, shared during a March 19 appearance on “In Depth With Graham Bensinger.” “In his 20s, he had the drug problems. God, I put him in rehab so many times. And every time he’d be doing great and then it would just fall back. It got really, really bad. Apparently, it wasn’t heroin. He ended up getting some fentanyl and it killed him.”

“The thing is when you lose a kid, you second guess f–king everything,” he continued. “It’s like, ‘Could I have done this? Could I have done this? Could I have done this?’ It goes through your brain constantly. There’s not a day I don’t go by thinking about him.”

“Could I have done something different? I think I did everything right,” Rick confessed. “And then you sit in your head, ‘What if I did this? What if I just grabbed him and f–king locked him in the back of my truck and drove him to Oregon where he couldn’t get it?’ I mean, you have a hundred things go through your mind. There is nothing worse than losing a kid.”

Adam was found dead on January 19, 2024, in the Last Vegas, Nevada, guest house he was living in at the time. His cause of death was determined to be due to “fentanyl and methamphetamine toxicity,” Clark County Nevada coroners confirmed to multiple media outlets on February 29, 2024, and that the 39-year-old’s manner of death was determined to be accidental.

Rick said he tried “tough love” with Adam after he broke into his home by having him arrested.

“I figured maybe if we put him in jail for two months it’ll clean him out, but he just went straight back on it,” he said. “You try to give him tough love but, God, you just never see the OD coming. You want to give them tough love and everything but I never thought that would happen.”

Adam had just been released from jail in the days before his death.

“Fentanyl turned my son into someone he wasn’t and that brought with it bad decisions and spending time in jail,” Rick told TMZ on January 26, 2024, following Adam’s passing.

The History Channel star shared sons Adam and Corey Harrison, 41, with his first wife, Kim Harrison. He also shares one son, Jake Harrison, 21, with his second ex-wife, Tracy Harrison.

“It’s hard. There’s no instruction book with kids. They’re all different models,” Rick told Graham, 38.

The World Famous Gold & Silver Pawn Shop owner’s growing family is what keeps him going.

“I think about the good times, and think about my other kids, my new grandbaby, my other grandkids. I got four grandkids. So, keep on moving on,” he explained. “Appreciate what you got, cause you’re not always going to have it. I spend as much time with my kids as I can. I talk to all my kids on the phone almost every day. I love my kids, love my grandkids.”
