First time publishing a song I have worked out!
 thought it strange that such an amazing song hadnt 
been put up here before... The song is not difficult, 
but the most important thing about playing this song, 
which can take some practice, is to listen to the rhythm 
and be strict with the muting; it makes the whole song 
sound so much clearer.

Anyway

Standard Tuning: EADGBe

no capo

Intro: 

C# \slide down the frets before triple flicking the body of the guitar

Verse:

C#       Bbm
  Yes Im a Ganja Planter
Ebm      Ab         
  Call me a Ganja farmer


This chord pattern is then repeated through the song


hope that was helpful
