who knows the true meaning of vectors song ''maryjane''

     I heard  the song was not really talking about a girl,they said the song has a whole different meaning than just talking about being in-love with a certain maryjane girl.In the song vector explained how he met maryjane and the things maryjane did for him.some people said maryjane in the song referred to marijuana(Indian hemp)
     Does anybody knows the meaning of the song?
