Urine samples are commonly used for drug testing. Many employers require their employees to take drug tests, and the results of these tests can have serious consequences. If an employee tests positive for drugs, they may be fired from their job. They may also have difficulty finding another job, as many employers require potential employees to take drug tests as well. This can lead to financial instability and even homelessness. Drug testing is often seen as unfair, as it can punish people who have never used drugs before. It can also lead to false positives, where people who have not used drugs test positive because of something else in their system.
