Go to the store and buy a box of sure-jell. It's in the jello aisle. It is basically a non-flavored jello mix. Mix with 1 gallon of water. Drink all of it no matter how bad. Do this 2 hours before a drug test. The flavorless jello/water mix hides the impurities in the urine. A cheaper way to do it. Costs about maybe 2.00
