Attempts to subvert the results of a toxicology screening involve actions taken to produce a negative result despite the presence of prohibited substances in the individual’s system. This may include dilution, substitution, or the introduction of adulterants to the sample. An example would be consuming excessive amounts of water before providing a urine specimen to reduce the concentration of detectable drugs.
The significance of understanding these methods lies in their potential to compromise the integrity of testing programs implemented for safety, legal, or employment purposes. Historically, the methods employed have evolved alongside advancements in testing technology, leading to a continuous cycle of countermeasure development and refinement of detection techniques. Consequences can range from overlooking substance abuse issues to jeopardizing public safety in scenarios where impairment could lead to accidents or harm.
