What are the advantages of drug testing on hair follicles?

The

benefits of drug testing on hair follicles include a longer detection period, lower chances of deceiving one of these tests and their relatively non -invasive nature. Testing the hair follicle is often considered to be more effective than urine or blood testing. Although the advantages of this form of drug testing can be numerous, there is some disadvantageous worth mentioning.

In standard drug testing on hair follicles, hair is usually removed from the head and their heads as close as possible to the scalp. A number of hairs are collected, and those with very short hair could lose several hundred in this process. It is also possible to take hair from armpits, legs or hair, but the last option, even if it is still not invasive, may be embarrassing for people. These hairs are combined with chemicals that decompose them, and if the test is positive, reveal evidence of the use of various abuses such as marijuana, angel dust, amphetamines and meethamphetamins and some commonly prescribed medicines.Types of drugs proven for impression may depend on the extent or type of test.

While the average urine drug test detects the use of a drug up to 30 days before the test, one frequently cited advantage is that the hair follicle testing is that hair assessment can show drug use up to 90 days. Evidence of drug use continues to live in the hair shaft long after the body and blood removes symptoms, and this evidence could be very important in any situation where there is zero tolerance for legal or illegal use of drugs. As with any drug testing, people may have legitimate reasons to use some drugs that are commonly proven and should present evidence of regulations that show that the use is not unlawful.

There are many urban legends about passing a drug test and even products that are sold that allegedly beat hair follicleYytesting drugs. Scientists find that these recommendations or special shampoos tend to work. Even chemically treated hair will still show evidence of drug use up to three months before. Another advantage is that cutting several hair, usually about 100, which is very minimal, is advantageous before providing urine or blood samples. In addition, concerns about things such as marijuana exposition from second -hand are excluded by testing hair; It will not be in the hair shaft.

The benefits of drug testing on hair follicles must be compared with things that detect from it. First, this testing is much more expensive and, unlike urine analysis or blood tests, does not have to detect the use of a drug up to five days after use. It is not the best choice to determine extremely recent use. This may be problems for people with minimal hair and some people are not happy to have a hair test instead of their head testing. Testing is also more complicated than the urine test and it is difficult toí do perform at home.
