eating 8 niacin a day did the trick for a long time (probably has something to do with my ulcer) I could smoke all I wanted as long as I ate 8 of vitamin worlds niacin each night. So theres noting that could flush my system out6 quick,huh?then why didnt i ever piss dirty when using this tecnique? granted I cannot stomach that many niacin anymore, But is that the only road I can take. I'm a fat ass, so i know being skinny dosent have anything to deo with why I didnt fail under that trick. But thats it, only Niacin can help it seems, fuck it! thats what i'll do!!! keep on puffin' everyone!
