I have no first hand experience in using niacin to pass a drug test, but i have done alot of research on the topic. if it was truly a reliable way to pass, nobody here would worry about taking a drug test.
tonyp Reviewed by tonyp 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
