Contrary to the belief of many people, it is extremely difficult to pass a drug test if you have been taking in illegal substances. Traces of prohibited drugs can be checked through your urine, blood, and even your hair follicle. Keep in mind that the screening may come in several forms. Depending on the substance and how long ago it was taken, there is a variety of tests that can be utilized.
Whenever you go for a drug test, the first thing that you need to do is to submit a so-called “sample”. Again, this can be your urine, hair follicle, or blood. The sample that will be taken from you will then be subjected to different types of screening, some of which may even be confused with a legal prescription from a health care professional.
Therefore, if you undergo screening, and you have taken prescribed medicines in the past, it is highly recommended that you take a medical certificate with you as well as the bottle of your medicine. This way, the tester will be able to verify that, indeed, you have ingested legal drugs.
If you are applying for a job, you are most likely to submit a certain amount of your urine as a sample. This is the most commonly used type of drug testing. However, it has imitations. There are some prohibited drugs that will stay in the system for a long time. If you have used cocaine, which is considered as a hardcore substance, it can be detected in your urine for up to five days. But on the other hand, this drugs can metabolize into a different form. And so, there is a possibility that it will not be detected.
Like what was mentioned earlier, a drug test can also be done using your hair follicle. While this type is the least invasive out of all the other types of screening, it can still detect drug abuse.
One of the most accurate ways to detect an abuser is through saliva screening. Drug users can be caught for up to two days after the intake of unlawful substances.
There are other more ways of drug testing, and each of them is getting better and better especially with the help of modern technology. So, if you have been taking illegal substances, take note that there is no better way to pass a screening than to stop using drugs.
