"In celebration of 420, here's an interlude from my 8th studio album that I call James Joint," she said.

420 is an annual holiday celebrated by cannabis enthusiasts around the globe.

The track follows the release of the third full track American Oxygen from her forthcoming, as-yet-untitled album.

The song, which was produced by Alex Da Kid, was released worldwide last week after previously only being available on streaming service TIDAL.
