How to Pass A Hair Follicle Drug Test at Work?


In 2015, at least 7% of workers in the United States, failed the hair drug screening conducted by their agencies or companies, because of marijuana or cannabis use. These are not occasional and one-off smokers who are just victims of wrong timing.

People who failed the screening are frequent users since the test is designed to detect regular drug users. You always need to remember that consuming marijuana or cannabis regularly will make it almost impossible to pass the follicle drug screening.

Nonetheless, there are methods that you can use to help increase your odds of passing with flying colors. Knowing how to pass a hair follicle drug test for weed and other narcotics means that you need to know how the screening, as well as how your hair works.

How weed ends up in the follicles of the hair?

The human body reacts to tetrahydrocannabinol and other cannabinoids in complicated ways. And the average result is that tetrahydrocannabinol and other cannabinoids, together with the metabolic byproducts of the illegal substance, ends up all over your body, including your scalp. Cannabis ends up in your scalp through your bloodstream.

And that is something exciting. Signs and symptoms of marijuana use can stay on the scalp for a long time, but cannabis only stays in the bloodstream for a short time. Usually, it stays in your blood as long as you are high. The body metabolizes or breaks down the cannabinoids in the blood rapidly.

But before it happens, drug components will bind themselves to the sheaths of cells and tissues surrounding the roots of the hair. It all happens underneath your scalp, but soon enough, these cannabinoids will get trapped in the follicles, and from there, it goes to the strands when your hair starts to grow

And finally, between five to ten days, cannabinoids-laced follicle will come out and it can be involuntary rat you out when you are subjected to drug screening. And that is the reason why it is very hard to fake or beat this drug analysis. It will only take a small amount of tetrahydrocannabinol to trigger a failing test result. One picogram/milligram, to be exact. For people who do not know anything about measurements, one picogram is equivalent to 0.000000000001 grams.

How long cannabis stays in the hair?

The bad news is, once the cannabinoids get trapped in the follicles and the hair strands, they will stay there until your hair falls or cut off. There is nothing you can do to change this fact. It is pretty unreal how long drug components can stay on your scalp.

According to studies conducted by the Forensic Science International, traces of illegal substance can still be found in the hair of thousand-year-old mummies in Chile and Peru. Unless you shave your hair or live thousands of years, there is no chance that you will get rid of drug components in your scalp

Passing a follicle drug screening

Usually, calling it follicle screening is kind of inaccurate. Sure, these screenings are looking for any forms of evidence that tetrahydrocannabinol was in the test subject’s system by detecting the presence of illegal cannabinoids in the fatty tissues and cells in scalp, but these types of analysis do not evaluate the follicles per se.

Instead, they test the tetrahydrocannabinol in the strands. A positive result implies that there are drug components found in the follicle and the bloodstream. It means that the test subject consumed marijuana or cannabis regularly. That is why lab technicians collect the hair itself, not the follicles.

With that in mind, hair that is closest to the scalp is considered as the new growth and is the best sample that can indicate recent cannabis use. That is why the laboratory technicians get at least 50 to 100 strands of the sample and the closest to the follicles. On average, the hair grows at about half an inch per month.

So, one and a half inches of the sample will amount to more or less three to four months or 90 to 120 days of the detection window. If you have ingested weed regularly during this detection window, there is a big chance that you will test positive. That is the key to understanding how to get a passing result for a follicle screening. Once you know the timeline of your cannabis use for the past three to four months, you can devise a game plan on how to beat or minimize your chances of failing these types of drug analysis.

How to get a passing analysis result?

Hopefully, your company will give you a warning when they plan to subject all their employees to a drug test. It will provide you with enough time to prepare your body. If your luck runs out and your company decided to test every one without any prior notice, maybe it is time for you to start updating your resume, because there is a big chance that you will fail the test.

Here are some of the critical things that you need to keep in mind

First, if you have only smoked recently, there is a big chance that you will pass the screening with flying colors. In fact, you can smoke as much as you want a day before the scheduled test, and still pass it. You need to remember that it will take five to ten days for a contaminated follicle to break your scalp.

Urine and blood analysis, on the other hand, will detect the most recent cannabis consumption. If you have only ingested cannabis a few times in the past three months or 90 days, chances are you will also pass it with flying colors.

Even though follicles tests for marijuana is very sensitive, only people who use it regularly will put enough tetrahydrocannabinol in the scalp to trigger positive results. If you are wondering how to pass this type of drug analysis without having to stop your cannabis use (whether it is for recreational or medicinal purposes), it will take a lot of time, luck and creativity in your part. Otherwise, this test will catch you red-handed.
