Lyrics deal with drugs, religion and human relations. The title of the album is a methaphor for everything that brainwashes modern society.

The band recorded the album in Ostudio 6 in Nova Gorica, with Cigo working as producer. They made great efforts to get the sound as close as possible to what they present us when playing live. Opium For The Masses is recommended to those who like Kyuss and Unida, Soundgarden, Nebula etc. because Omega Sun has one more specialty: their retro does not carry us in the seventies, but in the nineties.
