Athletes are often asked to provide a random Urine Drug Screen. In the world of professional athletes random drug testing has become commonplace. A urine drug screen is done to determine if the sample provider has used illegal drugs, alcohol and adulteration. Unfortunately there are many individuals that try to cheat the screening process and there are a variety of ways to try and do it. There are allegedly masking agents that are available but they usually prove ineffective. Researchers are quickly developing drug test kits that are able to detect the adulteration or attempt to dilute the sample.
