Contrary to common belief, voodoo (known as Vodun in West Africa) is not related to juju, despite the linguistic and spiritual similarities. Juju has acquired some karmic attributes in more recent times. Good juju can stem from almost any good deed: saving a kitten, or returning a lost book. Bad juju can be spread just as easily. These ideas revolve around the luck and fortune portions of juju. The use of juju to describe an object usually involves small items worn or carried; these generally contain medicines produced by witch doctors.
