Miller spoke openly about his struggle with substance abuse and depression. To manage stress during his Macadelic Tour in 2012, Miller began taking promethazine, and later became addicted to purple drank, also known as "lean". Miller told Complex in January 2013: "I love lean; it's great. I was not happy and I was on lean very heavy. I was so fucked up all the time it was bad. My friends couldn't even look at me the same. I was lost. " He quit taking promethazine in November 2012, before shooting his reality show Mac Miller and the Most Dope Family. In 2014, Miller was taking drugs daily, and felt that the final track on Faces, "Grand Finale", was "supposed to be the last song [he] made on Earth. " Recounting that period to Billboard in August 2015, Miller was "definitely way healthier" but not "completely" sober.  After stating he "hated" being sober in a February 2016 documentary, Miller had become sober for three months by October 2016, noting his better mood and maintained creativity.  However, when asked about his sobriety in April 2017, Miller said he was now "living regularly".
