Niacin is a myth. It does nothing to help pass a U/A.
Burnt Toast Reviewed by Burnt Toast on . Niacin...is it effective? yes i know there is a niacin sticky...but it has mixed replies...and no1 really says if they have used it successfully...i have a UA in 5 days... i didnt smoke for a 3 week period and then i smoked 2 hits 2 days ago... so im a little worried i might show up dirty...i just went and bought some niacin and took a 500mg dosage (burned me to hell) im wondering if this is even gonna be effective... anyone who has used niacin please tell me if it worked...
