What Causes False Positives in Drug Tests?
A person may be required to take a urine test that screens for illicit drug use for a number of reasons. Some companies request that employees take drug tests to ensure workplace safety. People who have been convicted of drug related crimes are often screened to detect whether drug use is ongoing. Whenever a person is about to undergo such a test, they may experience anxiety even if they haven’t consumed any illicit substances, due to the existence of false positives on drug tests. A number of legal medications can cause false positive results on a urine drug screen.
