"Love Is a Drug" is a song by former Westlife member Markus Feehily.

It was released in the United Kingdom as a digital download on 19 April 2015 through Harmoney Entertainment.

The song was written by Feehily, Steve Anderson and Tinashé Fazakerley, and produced by Mojam.

After Westlife split up in June 2012, Feehily launched his solo career.

[...] When Westlife finished, the rule book was thrown out of the window in terms of songwriting.
