Initially, the singer self-released the song under the title "Habits" on 15 March 2013 as her second independently released single. After Lo was signed to Universal Music, the track was re-released on 6 December 2013 under the title of "Habits (Stay High)" as both the second single from Truth Serum and the lead single from Queen of the Clouds.
