Drug Testing

One method of drug testing that is starting to gain popular is the hair drug test. A hair drug test or hair follicle drug test requires the collection of hair samples from subjects. Many people find this kind of drug test as very reliable method of drug testing because it can reveal a history of drug use as far back as 90 days.

How can this be possible? It is all pretty simple. You just need to remember that every single piece of food you eat, every drop of beverage you drink, and every molecule you breathe in leaves traces in different parts of our body. When you use illicit substances, they are absorbed by our body and traces can be left in our skin, scalp, and of course, hair. They travel to our hair through our bloodstream, and our hair serves as a storage device, storing information as it grows longer.

The hair sample that would be collected from you should have a length of at least 1.5 inches. It is best that hair samples should be cut near the scalp to reveal the most recent use of illegal drugs. In case you are bald or you do not have any hair on your head, hair can be collected from other parts of your body, like you arms and your chest, except in pubic areas. It is ideal to have at least a pencil-thick amount of hair to be screened and analyzed.

Many people find hair drug tests to be convenient because it is non-invasive, and you do not need to use bathroom facilities to comply with the sampling procedures. This kind of drug test also has a reputation for being accurate and reliable, which contribute to its growing popularity.

Some people think they can skirt hair drug testing by using hair masking products. However, this can prove to be of no use because a hair drug test analyzes information stored inside the hair shaft, and not merely those present on the surface of a hair strand.
