Screenings for Cannabis and THC in Hair: Facts and Myths

 

Hair drug tests are becoming a more common method of drug screening. But like most things you find online, there is a lot of misinformation when it comes to hair follicle drug screening. We are going to separate facts from fiction.

The benefits of follicle drug screening

Before we get to the most common misconceptions of hair drug testing, let us take a closer look at the benefits that this kind of testing is offered.

It is very accurate

Because follicle screening needs to be conducted by legitimate screening professionals, and because of the nature of the test, they are very difficult to cheat (if it is possible) and impossible to fake.

On the other hand, people who take other methods of drug testing, like urine, blood or saliva, can manipulate the result by drinking a lot of water to produce a diluted test sample. People can also use synthetic or fake urine or pass a sample collected from other people.

Hair follicle screening has a longer detecting window

While urine drug screening is considered as the weakest among the testing methods, hair follicle analysis can detect drug use for at least 90 days or three months. And depending on how long the sample that was collected, it can go up to one year. Because of these reasons, a lot of companies and organizations are starting to use hair follicle as a test sample to maintain their drug-free work environment.

Because of these reasons, a lot of companies, organizations and even government agencies are starting to use follicle drug screening to maintain a drug-free work environment. Now that we have covered some of the benefits let us go into more detail and address some of the most common misconceptions about hair follicle drug screening

Myth: Laboratories and clinics will not test you if you shave your head.

Fact: Your whole body is covered by hair, and they can use it instead,

There are times that people think they are off the hook if they do not have a single hair on their head. But follicle screening can be conducted using hairs collected from other parts of your body like the back of your neck, chest, back, arms, armpits, legs and even hairs from your private parts.

It will take you to shave your entire body, including your eyebrows to make follicle drug analysis impossible to conduct. People usually think that having short hairs will make it impossible for them to be subjected to drug analysis. But laboratory and clinics will only need at least two inches of sample for it to be a legitimate screening.

But they need a more extended sample if they want a longer detection window. One important note is that since companies and organizations want to know about the most recent use, the screening specialist needs to acquire sample as close to the subject’s scalp as possible. It will allow professionals to screen the latest hair.

Myth: Some products can cleanse the hair for any illegal substance components.

Fact: There is no proven way to 100% cleanse your follicle of illegal substance components, but there are ways how to pass a weed hair follicle drug test.

All you need to do is to do your due diligence and research about Macujo and jerry g method. They can’t 100% remove toxins and drug components, but there is no harm in trying. According to people who already used these methods, Macujo and jerry g are effective if used the right way.

When weed is ingested, it goes directly to the follicles through the bloodstream. Once it is trapped there, it is very challenging to get it out. What these methods will do is to penetrate the follicles and remove some of the components, enough for your hair to pass the screening.

Myth: People can use hair that was collected from combs and hairbrush

Fact: You can use it, but the result will not be conclusive

Parents are the ones who usually ask for a drug screening using hair from combs and hairbrushes owned by their children. While you can do this for the sake of peace of mind, it is not the most accurate way to test for an illegal substance. Not only that, it can’t be used in legal courts.

The problem with this technique is that it is very impossible to assign the sample to a specific person. It also can’t determine the time frame if the screening. Because of this reason, people performing the selection, refer to the individual as an anonymous donor.

You also need to remember that in case of a court-ordered drug screening, the result that was collected from an anonymous donor cannot be used as an evidence or are not legally defensible. That is why, using hairs from brush, combs or anywhere else can be done, but it does not really give you a definitive answer, just peace of mind.

Myth: Secondhand cannabis smoke can cause people to fail their follicle drug analysis.

Fact: The smoke you inhale from other people is not enough to for it to show on any screening, especially the hair follicle test.

People always ask if they can get a failed drug screening from a cloud of secondhand smoke. The answer is no; the secondhand smoke will not be enough to get a failed test. Unless you are around marijuana smokers in a closed room without ventilation or you smoke it yourself, rest assured that you will pass the follicle analysis with flying colors.

Secondhand smoke will involve passive exposure. It means that using cannabis, for example, you are not actually ingesting or inhaling the THC or the tetrahydrocannabinol, the active component of marijuana that gets people high. The amount of tetrahydrocannabinol in secondhand smoke is at its bare minimum.

It is 100 times less potent compared to the amount of tetrahydrocannabinol that you will get if you ingest cannabis yourself. Even in studies where the subjects are in a confined space with cannabis smoke, they did not test positive. You need to be in a very tight space with a lot of marijuana smoke for it to affect the result of the analysis. It means that if you are subject to a hair drug analysis after hanging out with cannabis smokers, there is a big chance that tetrahydrocannabinol won’t show up in the results.
