The so-called "market flushes" (detox products) are nothing but a big scam to seperate the credulous from their hard-earned cash. When they do work at all, they "work" via the principle of dilution. They "work" because of the water that youre required by the instructions to drink with them. The dilution factor is what serves as the "mask". They "mask" by diluting (thinning out) the THCA concentration in the bladder in an effort to bring the urine sample below the cutoff thresholds of the drug screen. The same thing can be accomplished for $$$ less by just using water and vitamin B2.

Drug testing had come quite a way from the days where a donor can simply down copius amounts of water to make a urine sample test negative. Creatinine and specific gravity checks have become lab SOP in recent years, and if the levels of these two urine constituents are outside of satisfactory ranges (due to copius water consumption), the sample would be ruled "too-dilute".

Therefore, when utilizing dilution techniques, it is all so important make sure the S/G and creatinine level is within satisfactory ranges. The steps to be taken to help maintain proper S/G and creatinine levels are outlined in the link in post #13.


As far as home testing accuracy goes, home tests function on the same principle as the instant assays used by the labs. While they are not nearly as accurate as the confirmation GC/MS test, they are obviously accurate enough to merit continued use by the labs for the initial screening.
