Eat Fatty Foods
It is a good idea to start eating more junk and high-fat foods a few days before the drug test. The main purpose is to slow the metabolism. Because THC is fat-soluble, a slower metabolism would help the body reabsorb this element and other components into fat cells before they can be processed by your liver and end up in the urine. On the morning of the drug test, have a huge breakfast with fatty foods as well. This can empty the bladder and reduce the concentration of drug residue in your urine. [4]
