What is a metabolite in a drug test?

A drug metabolite is

a byproduct of the body breaking down, or “metabolizing,” a drug into a different substance

two or three 12-ounce glasses of water at the same time can produce 10-fold diluted urine within only half an hour

and the dilution effect may last for hours. In most cases, this will successfully lower the concentration of some drugs (mainly marijuana) in the urine enough to produce a negative test result.

How do you reduce metabolites in urine?

Dilution is the main proven method to pass a urine drug test

. The idea is very simple, you simply take in extra water, and this dilutes the urine so that the drug metabolite level is now low compared to the water. This creates a few issues if you take in excess water only. One, the creatinine level will be too low.
