What do you mean I might have reversed my thinking? I never said less THC total is filtered. I understand dilution completely. I gave this explanation about 4 months ago. I have no problems understanding or explaining dilution.

You can't flood your body with water or fluids and clean it out like you would pressure wash your driveway. The rate at which THC metabolites are eliminated in urine is governed by your kidneys' glomerular filtration rate. Once properly hydrated, you cannot increase the GFR by increasing fluid intake. If you keep drinking and drinking fluids and your body didn't regulate itself, you would die. To control this, your kidneys will pull water from the body and eliminate it to make up for the excess fluids you are drinking. During this whole process, you will not make your kidneys work better because you are taking in excess fluids and going to the bathroom more often. You did not increase how effective your kidneys are eliminating THC metabolites from the blood. All you did was increase the amount of water in your urine.

When you drink a lot of fluids on the day of the test, this is know as the dilution method. You are not passing the test because you cleaned your body of THC metabolites. What you have done is you have decreased the concentration of THC metabolites in the urine by increasing water. Most drug tests are not zero tolerance. Most drug tests use a cutoff on immunoassay of 50 ng of THC metabolites per ml of urine. Some tests will use a different cutoff but we will stick to this one. If you increase the mls of urine your body is prducing an hour, your THC metabolite concentration will drop. For example, if your body is eliminating 25,000 ng of THC metabolites an hour and 50 mls of urine an hour, your THC concentration is 25,000 divided by 50 mls for a level of 500 ng/ml. That would be a failure. If you take in excess fluids on the day of the test and produce 500 mls of urine an hour your concentration is now 25,000 divided by 500 for a level of 50ng/ml.

Your dad passed because he diluted, not because he cleaned himself out. He increased the amount of fluid in his urine and the concentration of THC metabolites dropped. Same amount of THC metabolites were there when he got to work that day, only after being told of the drug test, he increased fluid intake, increased fluid in the urine, drop in concentration. Cranberry juice is a mild diuretic and also has mild anti-septic properties in the urinary tract (why women subject to frequent urinary tract infections sometimes drink a lot of cranberry juice). It doesn't clean you out though.

Some THC metabolites are eliminated through sweating but very very little. Most THC metabolites are actually eliminated from your body by your liver, bile, and feces. Aerobic exercise can help you burn more THC metabolites from your body because THC is fat soluble and if you increase fat cell turnover, this can help. So it is the aerobic exercise burning calories that is important, not the sweat you get from the aerobics.
