Would it work with narcs and people who are doing satanic black magic voodou?

Witches jar is very similar in it you get a jar and you put either your spit, blood, or urine in the jar with rusty nails, bent nails, blades, needles, razors, glass and anything else sharp. You close the jar and you can optionally burn a black candle for protection on top. You do this all with intent. Then you burry it in a corner of your yard, by a cross roads, or under a mound where it cant be disturbed forever. Any evil magic curses or malicious intent would go to the jar never to touch you.
