"Hand of Doom" is a song by the English heavy metal band Black Sabbath, originally appearing on their second album Paranoid, released in 1970.
Background
The song was conceived after the band had observed a growing number of US soldiers arriving in England from the Vietnam War in the late 1960s with severe drug addictions.[1] The song paints an unflattering picture of hard drug use for the purpose of self-medication. The lyrics were written by Geezer Butler while the music is credited to the entire band.
