Sweet Leaf

"Sweet Leaf" is a song by Black Sabbath from their 1971 album Master of Reality. The song is about recreational cannabis use and its positive effects. The song begins with a tape loop of guitarist Tony Iommi coughing from a joint he was smoking with bandmate Ozzy Osbourne.[1]  The song is an early and quintessential example of stoner rock.

 ==Other media[ edit] == The original version of the song has been made available and playable in music video game Guitar Hero 5 on March 29, 2010.[2]  A cover of the song is also available for download in the similar Rock Band series.
