I have been reading over the board and there is a lot of talk dealing with drug tests and the like. I hope to clear up a few myths by sending this letter to whoever reads it. NORML writes a piece of literature on the subject of beating piss tests and I have a copy. IF YOU HAVE ENOUGH TIME TO WASH YOURSELF OUT, drink lots of fluids and use diuretics like coffee, cranberry juice, and beer. Vinegar doesn't work and neither does phenylpropanolamine (the active ingredient in Dexatrim). The night before the test, drink as much fluids as you can stand and piss in the morning because morning urine is the "dirtiest". Prepare for the test by drinking more fluids and boost with diuretics. You can color your piss yellow with for a few hours with vitamin b-2 (found in b-complex vitamins). Use a 50- or 100-milligram dose. IF YOU HAVE A SHORT NOTICE, take an 80-milligram dose of prescription diuretic Lasix (furosemide), take a hefty drink of water, piss two or three times and take the test. WARNING!!! Diuretics can be harmful to people with kidney dysfunctions, pregnant women and diabetics.
