My ex boyfriend used to meet with his PO and he didn't get drug tested. But just in case, order online quickfix 4.0. It costs somewhere around 20.00 a bottle and I just passed my drug test with Qwest with it. It comes with a heater pack and its premixed, all you got to do is heat it up per the directions and wear two pairs of undies or not, depending on if the heat of it bothers you and take the test. You will pass with flying colors. It won't work if they watch you pee but I highly doubt that.
