A quick search for “how to pass a drug test” reveals hundreds of results, and thousands of pleas from drug-using employee and job applicants desperate for a way to pass their impending tests.  Their cries for help are met with suggestions and products to help drug users pass drug tests.

Many donors will attempt to dilute their specimens by drinking large amounts of water prior to taking their test.  When this happens they will have a dilute result, either the donor drank an unusual amount of water or water was added to the specimen after the donor made their “deposit.”

Other donors will add other products of chemicals to their urine specimen in an effort to mask any drugs present in their system.  These chemicals may even destroy the drugs or otherwise interfere with the laboratory analysis.

One of the most common methods donors use to cheat on a urine drug test is through the use of oxidizing adulterants.  An oxidizing adulterant oxidizes drugs or drug metabolites and either prevents the detection of them or affects the reagents in either the initial or confirmatory drug test.

Laboratories perform specimen validity testing to ensure the specimen does not have abnormal physical or chemical characteristics.  For employers wishing to maintain a drug-free workplace, this testing goes the extra mile to make sure that no drug test cheating has taken place.
