Here you go cazz... From the article.... "Many websites sell 'herbal cleansers,' synthetic urine or additives designed to foil screening, but most are gimmicks, said Steve Ferris, vice president of Advanced Workplace Strategies Incorporated, a California-based company that administers drug and alcohol tests." I suggest the good ole "dilute" method. Drink tons of water and cranberry juice and take a vitamin B complex to make your piss yellow.
