Following Mac Miller’s untimely death last year, three men have been indicted and accused of dealing counterfeit drugs that led to the slain rapper’s passing.

Per TMZ, a grand jury indicted Cameron Petit, Stephen Walter and Ryan Reavis. Prosecutors found that Miller received oxycodone pills containing fentanyl, which is a “powerful synthetic opioid 50 times more potent than heroin.” Cops have concluded that Miller crushed the pills, snorted them and died.

As previously reported, cops stated that Miller ordered from Petit, Petit ordered from Walter and Reavis delivered the drugs from Walter to Petit. As a result, all three men were charged with conspiring to distribute controlled substances that resulted in death. The media outlet also reports that each charge carries a mandatory minimum sentence of 20 years.

Unfortunately, fentanyl is now “the number one cause of overdose deaths in the United States.” According to Column Health, fentanyl is common because of its addictive quality. “Use of fentanyl, and consequently fentanyl-induced overdoses, is rising in pockets all across the country.”

The site continues, “Users are gravitating toward it because of the prospect of a more euphoric high, while dealers are gravitating towards it because it is a potent mixer than can enhance the addictive quality of their product. This combination has proven profoundly lethal, and drug deaths involving fentanyl more than doubled from 2015 to 2016, and are up 540% overall in the past three years.”

Although many fans are still mourning the death of the “Swimming” rapper, MusicCares is ensuring that Miller’s memory lives on. Back in May, MusicCares launched the Mac Miller Legacy Fund, which helps young people who are struggling with substance abuse. “These grants celebrate Malcolm’s life and legacy by funding two respected organizations that provide opportunities for young people to realize their talents and potential,” Miller’s family said. “It’s critically important to our family to fund a safety net for artists and musicians who are struggling with substance addiction. No life should be cut short for lack of expert help.”
