I will take a stab at this and say that exercising to the point of sweating is the best way to remove thc from you system. Unless I missed it you did not indicate how long it has been since you last smoked. If it was 40 days ago you should pass the whiz quiz by now anyway. I agree that it is not practical to dilute every day. Will you be watched or is it possible to use synthetic urine. If you have smoked recently this may be a good route to go.
