The song IS about his addiction to drugs which he's over now. It opens talking about his old girlfriend who was cuban and beautiful but very bad for him, and his reference to looking at the world from the bottom of the well is kind of like seeing the light at the end of the tunnel. he's so low already, but he can see what the world is like and where it is, he just doesnt know how to get from where he is to where he wants to be.
