Are you sure man?
Read the instructions of the test kit. It will tell you the same.

If you have been clean for 88 days there is no way you will fail my friend. The THC isn't stored in the body much more than 30 days.
Uhh, there have been quite a few instances of heavy smokers taking 90 days or longer to finally test negative. It all depends on the persons level of physical activity, metabolic rate, frequency of useage and many other factors.


If you are concerned then take diuretics the day before the test and drink 8 quarts of water to flush your system.
Diuretics may make you urinate frequently, but they do nothing to rid the body of THC. And THC is fat soluble and NOT water soluble. Therefore you cannot "flush" or wash THC from the fat cells like you can wash dirt from a car. Doesnt work that way (more on that in a moment).

THC is stored in the fat cells and remain there until the fat cells are burned for energy. When fat cells burn, the THC metabolites are released back into the bloodstream, filtered by the kidneys, and are deposited into the bladder for the eventual exit. The rate in which the THC metbolites are filtered from the bloodstream by the kidneys is unaffected by copius water consumption.

The purpose of drinking fluids is to temporarily dilute the THCA concentration that is present in the bladder. You are NOT eliminating THC this way, but rather youre "thinning-out" the THCA concentration in the hoping that the urine sample would register below the cutoff thresholds of a drug screen. As stated, this dilution phenomena is only temporary - once the fluids ingested had all been urinated out, the bladder is replenished with fresh THCA-laden urine by the kidneys and thus the donor would resume testing positive for THC.

There is nothing that can permanently rid the body of THC, other than time and fat-burning exercise.
