The cause of the untimely death of young rapper, Lil Peep, has been released to the public. 

Over three weeks after reports of his death, the Pima County Medical Examiner has released the toxicology report that reveals that Peep (born Gustav Ahr) died from an overdose of Fentanyl and Xanax. The report also confirmed that the death was accidental. 

A Deadly Mix

While fairly safe to use, Fentanyl and Alprazolam are a dangerous mix. Alprazolam, the generic name of Xanax, is a well-known anti-anxiety drug. 

According to Drugs.com, mixing fentanyl with alprazolam (and other drugs that cause central nervous system depression) is fatal. Other side effects include respiratory distress and coma. 

At the time of his death, Lil Peep's older brother, Karl Aher, suspected that the pill the rapper took might have been laced. 

"We [the family] have heard there was some sort of substance he did not expect to be involved in the substance he was taking," Oskar told People. "He thought he could take what he did, but he had been given something and he didn't realize what it was."

He also mentioned that his brother, Karl, had a healthy relationship with drugs. Moreover, there was no reason for the rapper, who was also a model and fashion icon, to take his own life. 

"He was super happy with where he was in life," Oskar added. 

Authorities found drug paraphernalia and evidence of an overdose at the scene. No foul play was suspected. 

Drug Cocktail

TMZ reported that the medical examiner also found traces of other recreational drugs in his system. Lil Peep tested positive for marijuana and cocaine. The YouTube star also tested positive for the painkiller Tramadol and other powerful opiates such as Hydrocodone, Hydromorphone, Oxycodone, and Oxymorphone. 

The medical examiner, however, did not find any traces of alcohol in his system at the time of his death. 

Untimely Death

Lil Peep was found lifeless inside his tour bus on Nov. 16, hours before he was scheduled to perform at a nightclub in Tucson, Arizona. He was laid to rest in a quiet memorial held in his hometown of Long Beach, California on Dec. 12. 

The music industry is mourning the untimely death of the emerging rapper who, a few months ago, has released his first and only studio album, Come Over When You're Sober (Part One). Fellow musicians such as Diplo, Sam Smith, and Pete Wentz of Fall Out Boy have paid tribute to the young artist. His ex-girlfriend, actress Bella Thorne, also expressed her grief on her personal Twitter and Instagram accounts. 

Look at that big fucking smile always lit up the room. Hearts are breaking everywhere. @lilpeep
