I understand nothing will get you clean overnight, but i'm going to start taking niacin daily since it couldn't hurt to try..
Niacin does nothing and will do nothing to rid the body of THC nor help pass a U/A. Not overnite nor at any time. Its an old urban myth.

There is no product that can rid the body of THC. Only time and exercise can do this.
