The Dreaded Hair Drug Test

The hair drug test is one of the most precise ways of determining whether someone has been influenced by marijuana or other substances. Most people who want to maintain their reputation and avoid jail at all costs dread this drug test because it's nearly impossible to manipulate.

Although it is less invasive than urine or oral swab test, it is also quite controversial because, according to some reports, a hair drug test is known to cause false positive results. So even if you didn't smoke yourself but only came in contact with it can cause your results to come out positive. For example, edibles, sebum contact, or secondhand smoke.

But until you can sort that out, it would be helpful to know,

How Long Does Weed Stay in Hair?

Even though the effects of marijuana or cannabis last only a few hours, traces of it can be found on your body and in your system for months. So if you've tested for drug use within 30-90-days, it is easily detected that you have been under the influence of a substance at some point in the last few weeks.

But how long does weed stay in your system or hair follicles to ensure you pass the drug test successfully? Let’s find out.

If you're using marijuana with non-THC components, it will not stay in your system for far too long. This is one hemp or other marijuana-based medicine that won't make you fail a drug test.

However, the main component that these drug tests are designed to detect is THC residue. One fact worth mentioning here is that 90% of THC is flushed out of your body within the first 10-days of substance use. But the residue or small traces of THC can linger on for months in your system.

And most of all, it can remain in your scalp or hair follicles for up to 3-months, which is why hair drug tests can detect THC more diligently than other methods. In addition, most drug tests can be manipulated using a marijuana detox kit.

But there aren't many ways to go around the hair drug test. Furthermore, you don't have to be consuming marijuana for it to appear on your hair follicles. Instead, it can quickly get into your hair via physical contact.

This means that if you have been near someone who smokes weed or touched marijuana, or if someone who takes marijuana touches your hair, there is a great chance you will test positive for weed. They can test positive for up to 90-days once you have been exposed.

Factors That Influence How Long Does Marijuana Stay in Your Hair Follicles

There is no way to be entirely sure of how long does THC stay in system. Also, a lot of users are interested in how long does delta 8 stay in your system.

But a few factors contribute to weed lingering in your system. Take a look below.

Concentration Level of THC

THC present in marijuana has varying levels. Some weed has a high potency of THC while some don't. If you're using weed with highly concentrated levels of THC, the residue will stay in your system for an extended period.

Frequency of Weed Use

Someone who uses marijuana regularly will have better resistance to THC than someone who consumes it occasionally. This is because it will take longer for marijuana to completely excrete from the body of someone who is habitual of it.

Methods of Using Marijuana

How you consume marijuana also affects its ability to excrete from your body. For instance, smoking marijuana will wear off within a few hours, and your body will flush THC out sooner.

However, if you ingest marijuana directly in your system, then your body takes time to break it down. Thus, it will take longer for your body to be completely free of the residue.

Your Body Weight & Marijuana

THC is stored in your body fat. So it will leave the system with less fat in their body than someone who doesn't.

Suppose you exercise regularly, maintain healthy body weight, and are active in your overall routine. In that case, marijuana will leave your system sooner than you hope compared to someone who is unhealthy.

Use of Other Drugs

If you’re consuming other drugs alongside marijuana, then it will also affect the detoxification process. Some drugs slow down the process that includes,

  1. Erythromycin
  2. Verapamil
  3. Ketoconazole
  4. Itraconazole
  5. Cyclosporine

Then drugs like rifampin can lower your body's THC level. THC also has different effects on different drugs. For instance, it can increase the effects of warfarin in your system, so you have to be careful if you're taking those.

How Does a Hair Drug Test Work?

When you’re using drugs, the metabolites accumulate in your bloodstream. As your blood flows through your system, the residue reaches every cell in your body, including hair follicles. This is why it is detected on your hair during a drug test.

The hair drug test requires a few strands from your hair as a sample taken directly from the scalp or roots. The lab assistant or the doctor will take only a tiny amount of hair and send it for analysis. The test results usually take 12-24 hours. However, you will have them within a day or two.

Substance That a Hair Drug Test Can Detect

The hair drug test can detect most substances. But, it is most commonly used for,

  • Cocaine
  • Marijuana
  • Amphetamine
  • Ecstasy
  • Methamphetamine
  • Opioids
  • PCP

A urine drug test can detect if you have used substances in the last few days. A hair drug test can detect the use of drugs in the last few months. Some employers determine the use of drugs by their current or potential employees using this drug testing method.

Although controversial, it is still recommended by various companies because of extended hair follicle drug test detection times.

How to Pass a Hair Drug Test?

If your employer has asked you to undergo this test, you're probably wondering how you can beat a hair follicle drug test. Well, there is no guaranteed way for you to beat it. But, as mentioned earlier, the hair drug test's longer detection window makes it unbeatable, and there is virtually no way around it. A lot of people use hair follicle drug-testing shampoo. A little bit lower, you will find an overview of such items.

But there are a few things that you can try,

Dos for Passing a Hair Drug Test

Only Use Detox Shampoos

The first and most certain way to pass a hair drug test is to start using hair follicle drug-testing shampoo. There are a couple of detox shampoos available that might help you pass the drug test. This includes the Old Style Aloe Vera Toxin Rid Shampoo.

It is one of the most popular detox shampoos that guarantees results. However, working effectively requires at least 10-15 days.

Home Remedies

You can try to clean your system with a few home remedies available but don't expect guaranteed results. Also, don't believe everything you see on the Internet because you can end up damaging your hair for good in that way.

Try the Macujo method. First, you must stop the use of marijuana entirely. Then take vinegar, damp, and massage your hair, including the scalp, for about 10-minutes rigorously. Leave the mixture on for at least half an hour. Rinse thoroughly and repeat every day for 20-25 days.

There is no guarantee, but vinegar can help you flush out toxins sooner.

So, these are a few dos regarding how to pass a drug test.

Don’ts for Passing Hair Drug Test

The Internet is loaded with unverified information these days. You don't want to cause more trouble for yourself, so don't believe everything you see. Here are a few things that you shouldn't do if you'd like to pass a drug test.

Abstain from Marijuana

The first thing you mustn't do is consume more marijuana if you want the detoxification process to work. If you continue using marijuana while detoxing, your result will never be negative.

Don’t Shave Your Head

Some believe that shaving your head will help you pass the hair follicle drug test, which is invalid. The hair drug test requires a strand of hair from your scalp. So even if you shave your head, doctors can still take the sample from your roots.

So, losing your hair for something that won’t work in the first place is a bad idea.

Never Bleach Your Hair

If you're thinking about using bleach to remove toxins from your hair, that will also not work, and you will damage your hair. Although, there are a few people who believe that bleach can get rid of 40% of toxins in your hair. But there is no scientific evidence for this, so better to abstain.

Lice-Treatment Shampoo Doesn’t Work

Lice-treatment shampoos are also flawed since they contain piperonyl butoxide, pyrethrum, and pyrethrin extracts, all insecticides. It can also not get rid of toxins and metabolites from your hair.

Are There Specific Employers Who Use Hair Drug Tests?

There is no said list of employers that use the hair drug test to determine substance abuse or unhealthy use of prescription medicine among employees. It depends on the company’s needs and preferences.

The companies can choose any testing method, such as urine, hair, or oral fluid. If you are an employer, you should compare the pros and cons of all these tests and then choose one.

Conclusion

Even though the hair drug test is not invasive, it is still very intimidating because of their long detection window. In addition, it can detect physical evidence of a substance when the person may not even be under its impression, making it controversial and difficult to pass.

Most employers go for urine drug tests because it is far more conclusive than any other test; some employers prefer hair drug tests for the detection times. The bottom line is that you cannot avoid it if your employer has decided on this drug test method for the company employees.

To pass the drug test, you can abstain from marijuana at all costs until the drug results come negative. Then, try using the detox shampoos we have suggested and go on a complete cleanse. Of course, that doesn't guarantee the test results will come negative, but it at least gives you a fighting chance.
