Aaron Carter willingly submitted to a drug test on Thursday’s episode of “The Doctors.”

In the results, Dr. Travis Stork revealed Carter, 27, tested negative for meth and cocaine, but he did test positive for several others drugs, which concerned the doctor.

“What scares me about the drug panel is that your sister [Leslie] perished from a drug overdose,” Stork added. “You have a mixture of benzodiazepines and with opiates, which is how many people accidentally can die. These medications, and I’m speaking now purely from the doctor’s perspective, can be very, very scary.”

Carter says he often turns to prescription medications to cope with stress and anxiety. Stork says using the drugs doesn’t address the problem.

“I don’t want to be on that stuff!” Carter shared. “My sister passed away from it. It’s not OK. I don’t take it every day. To be honest with you, it’s not going to be easy. I know that it’s a hard road.”

He also confessed to buying drugs on the street. Elsewhere in the lengthy interview, Carter discusses his weight. He says stress is stopping him from gaining weight. He also admitted to having chest pains.

Carter’s weight — a skeletal 115 pounds with clothes — was also revealed.

“I didn’t realize I was 115 pounds. That is terrible,” Carter said. “I wasn’t looking at myself in the mirror because I didn’t like the way I looked.”

Dr. Jorge Rodriguez said Carter’s body mass index is 17, “which is critical. So, if nothing else, that right there says something bad is going on.”
