so you don't think the drink works?
As I already stated, detox potions work via the principle of dilution. When they do work, its because of the fluid consumption associated with the products use. When ingesting fluids as instructed, you are diluting - not much to be flagged for being "too-dilute", but enough to effectively reduce the concentration of THC metabolites present in the urinestream, so the urine sample registers below the cutoff threshold of the home test.

The actions of dilution techniques are only temporary. Once all of the fluids taken in had been voided out, a "dirty" donor is going to resume testing positive for THC.

Dilution techniques, in any configuration, can backfire if the concentration of THC metabolites is too high. For most heavy smokers, it is impossible to dilute without overdiluting and raising the red flags.
