Miller had been candid about his struggle with drug abuse in interviews and his music. Before his death, he spoke about an accident in which he was arrested on DUI charges in May.
“I made a stupid mistake,” Miller told Beats 1 radio host Zane Lowe July 23. “I’m a human being. Like, (I) drove home drunk. But it was the best thing that could have happened. … I needed that. I needed to run into that light pole and literally, like, have the whole thing stop.”
Miller, whose last album, "Swimming," was released in August, spoke to Vulture in a profile published Sept. 7 about being honest about what he was dealing with in his music.
“That’s the goal, to get better and to try to make this (expletive) the most of a reflection of who I am,” he said. “I used to rap super openly about really dark (expletive) because that’s what I was experiencing at the time. That’s fine, that’s good, that’s life. It should be all the emotions.”
