“Drug Tests” or Drug Screenings occur in 2 phases; Screening and Confirmation. Talking about ‘Screening’ in particular in this post, it involves the collection and analysis of blood, hair, saliva, and urine samples in order to identify chemicals left behind in the body due to the usage of drugs. Let’s first talk about these drug screenings in detail:
Saliva Drug Screenings
This process requires just a swab of your mouth. The drug can only be detected in the saliva in 7-21 hours, so the detection period is short. Police widely use this test on highways to check intoxication while driving. This ensures the driver’s safety.
Urine Drug Screening
The most popularly used method in the United States is urine drug screening. Not only is it cost-effective but also has a simple collection process. However, the procedure is time-consuming (it takes several days to complete). The tests are done at clinics or testing facilities and then sent to laboratories for screening and results.
Blood Drug Screening
This is the least popular method of drug screening due to its invasiveness, short detection window, and high cost. Regardless of its disadvantages, it’s sometimes preferred because it can reveal toxins within minutes. Moreover, it can measure the exact quantity of illegal toxins in the body.
This method has the longest detection time. Even someone had cocaine months ago this test would detect it. A strand of hair acts as a complete guide to a person’s intake history. This type of screening is also expensive ($100 per test), and this is the reason it isn’t commonly used.
What These Tests Do and Why Take Them?
These tests mainly check alcohol, cocaine, marijuana, methamphetamines, phencyclidine, oxymorphone, methadone, and the use of other drugs in the body. Drug screenings ensure not only your safety but also the safety of others around you. These examinations help create a healthy, drug-free environment where everyone can work to their full potential.
Who Should Take These Tests?
People take these tests for various purposes. Some companies require their employees to take these tests before hiring them. Some use it to detect “performance-enhancing” drugs used by professional athletes. Random drug testing is also practiced on prisoners in the judicial system, and at times, the traffic police take driver’s tests to confirm that they are not driving under the influence of any intoxicants. Everyone has to take them at some point in their life.
