Mac Miller's ex Ariana Grande made it clear that she thinks Cameron James Pettit should suffer the consequences of selling Mac the Fentanyl-laced drugs he ODed on.

 Mac's dad Mark McCormick feels the same way.

“So they finally caught that motherf**ker”

"So they finally caught the MF that sold him the drugs that killed him.  And we find some comfort in that. Many of us who were young, including me, experiment with drugs. But it's a different f*cking world out there. All it takes is a little tiny stone of Fentanyl and cocaine and you're dead. Drugs are being laced with Fentanyl, all kinds of drugs." Mr. McCormick told the crowd. "The one thing I would say to you is don't take the risk. It's just not worth it."

Pettit was arrested last week and is being charged with one count of distribution of a controlled substance, which carries a maximum sentence of 20 years. He could still face additional charges.
