fake boobs you know it all don't you. ya we've gone at it before because you point out stupid fallacies and grammatical errors and only troll around in the drug testing section trying to "prove" everyone wrong. Where is your proof niacin has ANYTHING to do with scientology and L Rob Hubbard? Niacin is a B vitamin found naturally that helps with energy production you fool it has nothing to do with Hubbard. You are just a nay sayer and pessimist is all. You work in the medical profession and you deny that water helps flush out your system and thus helps in passing drug tests? Oh I guess everyone on the forums and for the last 80 years is wrong in thinking water has had any effect on cleansing your system wow, Don't bother writing back cause you are permanently on the ignore list buddy.
