Since its release in the early 2000s, the hair drug test has become the fastest-growing form of drug test used by US employers and government officials today.
Just last month, Louisiana joined the chorus of states approving the hair test for use in parolee monitoring and employer drug testing.
It isn’t difficult to understand why: for the most part, hair drug tests are very effective. In fact, more and more employers today are favoring hair drug tests over urine tests, because the drugs remain detectable in the hair longer.
In response, some people think they can cheat a hair drug test, because they believe the hair can be cleansed from all signs of the drugs; but, that is far from true.
So why is the hair drug test so hard to cheat?
How Hair Drug Tests Work
New growing hair is fed into the follicle from the body’s blood stream.
When drugs enter the system, it goes straight into the blood. The drugs or chemicals given off by reactions with the drug enter into the hair follicle.
Through the follicle, chemicals are dispersed throughout the body of the hair evenly, not concentrated on the surface. This is why even if you wash your hair thousands of times over, drug traces will remain within the hair and can be picked up.
Even the slightest traces, very small particles can be picked up. That is why this has become a popular drug test to administer.
There are lots of different drugs tests out there and while many of them are good, not all of them are able to pick up the traces of drugs from months ago.
The hair drug test can in fact pick up the slightest trace of drugs for up to three months. This is why there are going to be more and more employers and governments moving to the test than ever before.
Mostly Fool Proof
To be honest, there are going to be more employers and courts who order a hair drug test than any other drugs test simply because it’s mostly fool-proof.
Most drugs remain within the hair follicles for an extended period of time and it means they are accurate. This is why there are going to be more who choose to use these types of tests than ever before.
Of course, there are lots of drugs which can be picked up via normal drug testing but hair testing can actually be more effective and offer better results.
Should Hair Testing Be Used
Drug testing comes in every form and while some of them are good to pick up most drugs found within the system, many offer have short time frames. These shorter time frames don’t provide the right details for those who need longer checks.
That is why there are going to be more and more people who choose to go for the hair follicle drug test than any other. Of course, every person is different but most courts may order a hair follicle drug test for those who have had history with drug abuse, especially when it comes to child custody cases.
