Lyric discussion by like you meant it 

I dont think it's about a drug addiction at all..it's definitely written about a person. Dido's songs all have that really haunting quality that makes them incredibly touching and sometimes creepy

Its definitely about addiction. Dido clears it up for everyone, and also apologizes if they've used in at their wedding coz it's "definitely the wrong song", before performing the song live at Brixton in 2005.
