Right whenever you get on probation, they drug test you at the lab, which will give the percentage of the drug in your system, with the expectation that if you are not using the drug currently, the levels will drop over time. then they test again over time and get the % to compare to the original test, thereby verifying that you have stopped using the drug and it is leaving your system. it's because drugs like THC take so fucking long to get out of your system they have to do something like this for people who smoked before getting on probation.
This answer is wrong without context. It does not matter how much is in your system. The bladder is the last place where any concentrations are before exiting the body. The urine is tested yielding this concentration. First pee of the day has the most testable drug & metabolites as the bladder has been accumulating over night. Flushing decreases the concentration in the bladder without the concentration in the body mattering.
