Vitamin B

[v4v4v04]

I read somewhere that I should use vitamin B to change the color of my piss for the dilution method...well I just read vitamin B2 (riboflavin or something?) can produce a false positive for marijuana on a drug test? Whats up with this?

I don't know about B2, but taking B vitamins will most definitely turn your urine yellow. B vitamins also help you keep your brain working properly.
