I would say as part of a dillution plan that they could help. I know that lasix does. Not in the weeks before, but in the hours before on the day of the test. THC is a fat soluble, not water souble.You cannot wash it out. Excercise and your bodys excretions do the job. Excess water way before the test does nothing but make you piss. It is good to be hydrated don't get me wrong, But drinking excess gallons a week before the test is a torturous unnecessary thing to do.The items you suggest may help but this must not be the only angle you take. There must be a comprehensive approach to be successful. Follow the dillution sticky. exercise and fiber in the days and weeks preceding and meat eating, b complex, asprin and couch potato lifestyle a day or 2 before the test.
