This testimony discusses the ease with which the public can obtain products that are marketed, designed, and sold to defraud urine drug use screening tests such as those administered in the Federal Workplace Drug Testing Program. For purposes of this testimony, these products will be referred to as masking products and ways in which some businesses peddle them on the Internet will be discussed. Masking products fall into one of four categories: (1) dilution substances that are added to a urine specimen at the time it is collected or are ingested before an individual submits a urine specimen; (2) cleansing substances that detoxify or cleanse the urine and are ingested prior to the time that an individual submits a urine specimen; (3) adulterants that are used to destroy or alter the chemical make-up of drugs and are added to a urine specimen at the time that it is provided for testing; and (4) synthetic or drug-free urine that is substituted in place of an individual's specimen and provided for testing. This testimony today summarizes our findings.
