While this may not be a problem for those people who have ever ventured in these territories for those that did dabble in it before, this may cause an issue. If you happen to have a checkered past and you would not want it to interfere with how you are trying to rebuild your life right now, getting to know some essential facts about drug testing is crucial.

A lot of people would tell you that the hardest drug test to pass would have to be hair test, the reason for this is because it goes back way much longer when compared to how much urine testing can trace back your history.

When the substance is ingested, they go to the hair follicle. Then, they settle to the actual strands afterward they usually stay there pretty much forever.

Now, hair has an average growth of 5 inches per month. This means that there is a very good chance that when your hair strand tips are tested, drugs that you have consumed even three years ago can still be found there.

This is basically the reason why a lot of people have dreaded the possibility of getting tested through their hair.

However, people should be informed that when it comes to standard testing through hair, it is not really the end of the strands that will be done so. In fact, nobody really tests the end of the hair strands these days, the police can, of course.

But you are not being suspected of any crime. You just needed to go through the test to get that job.

The standard for the hair tests us to take 1.5 inches of hair, which are cut from the root. The rest of the non-rooted hair is then discarded. This is to make sure that the part that will be tested is only going to cover an approximate three months.

What is true though is that body hair grows at the very same rate as normal hair. The only difference is that body hair stops growing once it reaches the maximum length.

In both the body and the hair, a dormant strand is then replaced with new ones. The new strand will push them out which uses the hair to shed in the process.

When the hair is dormant, there is no way for drug deposits to get into it. So, dormant strands tend to only be able to deposit substance residues for longer than 4 months.

Cocaine, opiates, PCP, and methamphetamine are drugs that are easily excreted. This is why they tend to be detectable especially if the urinalysis has been performed 72 hours after the chemicals have been used.

When it comes to detecting the drug content in the hair, it is only limited by the length of the hair sample. This is why it is able to detect up to a standard of 90 days in most tests.
