The Voice of Cocaine

Do you know that you should fear me? Do you know what I can do? You believe that you are free But I'm controlling you At first you kind of like me Just nice to have around But eventually you'll need me Together we'll be bound And then the battle will be It's sure to be a long and lonely fight And you've convinced yourself that I'll will Even though it isn't right You have a chance but only one Turn your back and walk away But if you do that I'll have some fun I'll haunt you night and day I'll be everything you need And own the soul you try to save I'll either leave your heart to bleed Or I'll put you in your grave
