Aaron Carter recently subjected himself to a drug test on “The Doctor.”

In the trailer released for Thursday night’s episode, a tearful Carter admits that he’s bothered by people’s negative comments about his physical appearance. “I’m concerned about my overall health because people tell me I look like I have AIDS or I look like I have cancer or I look like I’m dying,” he said.

After subjecting himself to a publicized drug test, the results came back negative for cocaine and meth. However, the singer tested positive for THC or marijuana, Xanax, benzodiazepines, opiates and hydrocodone.

Doctor Travis Stork expressed his concerns over the substances that were found in Carter’s system. “What scares me about that drug panel is that your sister, Leslie, perished from a drug overdose. You have a mixture of benzodiazepines 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,” he said.

Carter explained to Dr. Stork that he takes the medications to help treat his anxiety and deal with his extreme stress. Nick Carter’s younger brother added that he’s finding ways on how to cope with his issues without having to take the drugs. “I don’t want to be on that stuff. My sister passed away from it. It’s not okay. 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 said.

Just months after his DUI arrest, Carter was involved in a car accident that did not injure him or anyone who was involved. The “I Want Candy” singer claimed that he injure himself and broke his nose following the incident. However, a source clarified to Entertainment Tonight that no one got hurt.

“Police were called to the scene and drove Aaron home and his car was towed,” the source said. Carter’s rep also released a statement, saying, “Fortunately no one was injured. Aaron is fine and resting at home.”

There were also some claims suggesting that Carter is suicidal since police were called to his house a couple of times before they decided to take him to the hospital.
