Killerweed420 is correct... A high fiber diet and exercise is your best bet. The water loading and niacin will not help you. Just stay hydrated as you exercise you don't have to overdo it. Pick up some metamucil, it will help you to excrete some thc through your colon. You said you have 7 days until your possible test(court date) which is now 5. Exercise and load metamucil for the next 3 days and then go into hibernation(be lazy, eat a lot of red meat and fatty foods). The morning of the court date follow the dilution sticky and you've got a good chance.
