Test for Drugs and Psychotropic Substances

Drug tests can be defined as the technical analysis performed to determine the presence of one or more prescription or illegal drugs in your system.

Individuals who are to be tested for drugs are required to provide a sample from their bodies. Then, during the test, the sample is scanned for specific chemicals and substances related to a particular drug. If these substances are detected, the test is deemed positive.

Our goal here is to explain who needs to undergo drug testing, and we'll also be looking at the different drug tests. So, without further ado, let’s get started.

Test for Drugs

Who May Need to Take a Drug Test and Why

Drug testing may be required in many situations, and you will be required to schedule it timely.

When you're applying for a new job, the employers will ask you to go through drug tests and show your report that says you're clean. If you're involved in a criminal or motor vehicle accident investigation, you may also be required to get drug tests done.

Moreover, drug testing may often be used to monitor the treatment if you're getting drug treatment. Other than that, professional athletes are also tested for drugs like steroids that are used to improve their performance.

Types of Drug Tests

There are many drug test types, each requiring different samples from the person's body. To have a better insight, let's dive deep into these tests.

Blood Drug Test

Blood drug tests are usually performed in emergencies and when the testing window is relatively brief. You might not know this, but depending on the type of drug and the dosage, drugs can be detected in the blood within minutes to hours.

In comparison to other testing methods, collecting the specimen for a blood drug test is more invasive as it requires a small amount of blood from the vein.

Urine Drug Test

A urine test for drugs is considered to be one of the most established testing methods. One of the prime reasons behind this is that this test has a detection window of up to 30 days. As you might have guessed by looking at the name, urine is the testing specimen and is checked for metabolites – a byproduct produced when your body breaks down a drug substance.

Other than that, the urine test for drugs can also analyze antigen-antibody complexes that form when antibodies are released by your body when a drug enters your system. However, in some cases, urine samples can tamper, affecting the test results.

Nail Drug Test

Like a hair drug test, a nail drug test also offers a long detection window, between 6 to 12 months. The sample collection for nail drug tests is fast and non-intrusive and can be performed anywhere under the presence and supervision of trained collectors.

Even though nail tests are tough to cheat on, you can't use them to indicate the pattern of drug substance use. They can only detect whether a substance was used, not when it was used.

Saliva Drug Test

A saliva drug test is also known as a mouth swab drug test and is an oral test for drugs. The procedure of this test involves swabbing the mouth for a drug test, taking saliva, and testing it for the use of drugs. Since saliva is easy to swab and evaluate, this test is considered simple and less invasive.

DNA Test for Drug Addiction

The procedure of DNA tests is quite simple and requires a quick swab of the cheek. Even though DNA testing isn't as precise as the researchers like, it isn't foolproof. It can yield valuable information, but experts agree that you shouldn’t put too much faith in genetic testing alone.

Hair Drug Test

Hair drug tests require the individual to give a strand of hair from his face, head, or armpit. Hair drug tests prove to help provide accurate information regarding the cumulative substance use by the individual.

Hair drug tests can be used for the detection of the following:

Phencyclidine (PCP)

You might not know this, but a hair drug test offers the most extended drug detection window out of all the testing methods.

Scalp hair – 3 months
Body hair – 12 months
However, the only downside to drug testing with hair follicles is that they might not be able to detect single-use cases or low-level dosages of drugs.

Features That May Affect the Result of a Drug Test

Drug tests serve as a snapshot of a specific period, and several factors can significantly impact the result. For your ease, we've listed some of them down below.

Wrong interpretation by an untrained professional
The prolonged time between sample collection and testing of the sample
Excessive water consumption before a urine test
Diluting urine sample or adulterating it with nitrites
The hair sample is taken from the wrong person
External contamination
