According to the Midwest medical Examiner's office, the drug found in his system was fentanyl, a powerful synthetic opioid which is 25 to 50 times more potent than morphine. It's mostly used to treat patients with severe pain, such as those undergoing cancer treatment, recovering from major surgery or those more tolerant to opiates.  

The report does not reveal much detail, other than the cause of death being stated as "The decedant self-administered fentanyl", with a box marked "accident" next to manner of death. It also details the artist's height (63 inches/1.6m) and his weight (112lbs/50.8kg) and that he was wearing a black cap, black shirt, great undershirt and black pants when he died.

Though it's been stated that Prince used painkillers for his hip, since his death on April 21, various sources have come forward to reveal his alleged long-time addiction to prescription drugs. One report states that on April 15, Prince's private jet had to make an emergency landing in Illinois so that he could be treated for a suspected overdose.
According to an attorney  working for opioid addiction specialist Dr Howard Kornfeld, the day before Prince's death, he was called in to help the musician with his addiction. Kornfeld, unable to attend immediately, sent his son to evaluate the singer, and sadly, when Andrew Kornfeltd  arrived at Paisley Park, he found the 57-year-old artist unresponsive in an elevator.

The findings are a very sad turn in Prince's death, who like so many musical icons before him - Michael Jackson, Jimi Hendrix, Janis Joplin, Jim Morrison, Amy Winehouse, Whitney Houston, Elvis Presley, and so many more, has been lost to vice.
