I stopped after reading this:

To the Neigh Sayers and Dbags
We’re tired of people saying that a marijuana THC Calculator like this is "too complex" to figure out. It's "too hard" and there's "too many variables."

In order to safely cleanse your body, it is also essential that you drink approximately 7.97 glasses (8-ounce) of water per day.
Anyone with a shred of knowledge of the human body and physiology knows that even the concept of some sort of formula/calculator for THCA unloading is ludicrous for the reasons stated on these forums ad nauseum. The only thing that is right on that site is that detox products are useless.
