yea, i've taken niacin before but haven't had results on the test because it hasn't come yet...
but yea i heard it supposidly burns it outta your system, and then i've heard that they can tell you've taken it when the results come back

so not real sure about it....
crunksquirrel Reviewed by crunksquirrel on . Niacin? I picked up a bottle of niacin from CVS and i was wondering if this stuff is legit. I read alot of stuff about it online and everything was like "many people think niacin help flush the body of THC" but nothing actually said it works. So i was wondering if anyone actually used it and got clean pretty quickly? Rating: 5
