Kinds Of Drug Tests
A confirmatory test is a common thing for urine or saliva drug tests when someone tests positive for drugs. They do it to strike out the chances of mistakes. But hair drug tests don’t need a second test. Thus, federal government departments and many corporate organizations like to perform follicles tests before recruiting.
A urine drug test has some drawbacks, and one of them is detection window. THC doesn’t stay in urine for months. This is why nowadays employers prefer to use follicles tests. So, if you have a pre-or post-employment drug test it is more likely they would ask for a hair drug test.
It might be hard to beat a hair drug test but it is not impossible. You would find many detox products in the market that can help you pass the test. Some even claim to work in just 24 hours. In this article, we are going to help you understand what a hair drug test is, and how you can pass it along with the do’s and don’ts.
So, What is This Hair Drug Test?
As the name suggests hair sample is used in hair drug tests. It has the longest drug detection window of 90 days. If someone smoked pot and took a follicle test within 90 days he or she is going to test positive. The same goes for other types of drugs. That’s the answer for the question, how long does THC stay in your hair.
How Does Hair Drug Test Work?
When you use drugs, the drug metabolites get mixed in your bloodstream. From there it reaches every cell of your body. The drug residues go up to your hair follicles too via the blood vessel. That’s why when they test the hair sample of a drug user it detects the existence of drugs.
For the test, the lab assistant or a doctor would cut 1.5 inches of hair from the roots. But don’t be alarmed since they wouldn’t take only a small amount. They might collect the sample from multiple places on your scalp so it is not noticeable. Afterward, they would send the sample for analysis. Within a few days, you would have your test results.
How Long Does Marijuana Stay in Your Hair Follicles?
As mentioned, like any other drug marijuana stays in your hair follicles for 90 days. The drug detection window for follicle tests depends on the amount of time that usually takes hair to grow past the scalp. Another important fact here is the part from where the sample would be taken.
Reliable sources report that new hair starts to grow within 5 to 10 days. Also, each month our hair grows about .5 inches. And the lab testers need 1.5 inches of the hair sample from the roots to run a follicle test. So, if you do the calculation, it is easy to understand that you would need 90 days for complete detoxification. So, if you are a weed user and take a hair drug test before that you would test positive for marijuana.
What Can Be Detected in A Hair Drug Test?
Well, now you know, how long does THC stay in your hair. But what to do with this scary fact? Don’t worry, we have a solution for you!

Can hair drug tests give false results?
A hair drug test is a great way to determine whether an individual is a frequent user of unauthorized substances. The test that’s conducted can show three results, i.e.,
A positive result means that the lab found drugs in a person’s system. Such samples are usually sent for further testing to determine and evaluate the conclusion.
Negative results mean the laboratory could not find any drug metabolites in the sample. After a proper evaluation, the results are then shared with the individuals.
Hair samples have the risk of getting contaminated or damaged. In this case, the laboratory is unable to perform a proper test. Additionally, the test is deemed inconclusive if anything goes wrong at the lab or the test doesn’t show satisfactory results. Therefore, one might send in another sample for a retest.
Factors for a false drug test result
It’s imperative to note that a hair drug test can provide possible results within three months of taking the sample. However, if the period has passed, the test and results can get influenced due to the environment and not be accurate.
In short, yes, a hair drug test can give a false result. So, what factors affect the reliability of the test? Here are a few reasons why:
Artificial hair dye
If a person dyes or bleaches their hair regularly, the hair drug test may show wrong results on the hair sample. Bleach is a powerful chemical that can remove traces of drugs from the hair. Additionally, it may cause certain drugs to be absorbed by the hair, showing wrong results.
Hair type and color
Melanin gives the hair its color. The more this compound is present in a person, the darker their hair is. According to studies, drug metabolites attach more to melanin, so a person with darker hair may show higher traces of the drug as compared to a light-headed individual.
The hair typically grows half an inch every month, but this is an average number, and different people can show varying results. So if an individual’s hair doesn’t show as much or grows farther than average, it can impact the test results.
Area of the sample
Lastly, the area of the head from where the sample is collected can also influence the result. The testing guidelines suggest that the model is collected from either the crown or the nape of the head. But if the hair is collected from any other area, this can influence the result by up to 20%
Conclusively, there are many reasons why a hair test can give a false result. Many factors are controllable, but others are purely natural, so having an accurate test result depends on the situation and other factors
What factors affect the time weed stays in your system?
THC or Tetrahydrocannabinol is an active compound found in weed. This compound is the amplest and primary substance present in cannabis. It is responsible for giving cannabis users the ‘high’ that the drug provides. So, the time weed stays in a person’s body depends on many things, the main factor being THC.
Here’s a list of reasons that can affect the time duration of weed in a human body.
The top factor is the quantity of weed. If you use it a little, it can easily and readily be excreted out of the body. On the other hand, overdosing and inhaling a lot of weed can make it difficult for the body to process the drug.
People either consume this drug as a stress reliever after long intervals of time or smoke weed all day, every day. So, the usage will naturally affect how long does thc stay in the system. An occasional puff will not take long to leave the body, but if you load a high quantity of cannabis regularly, it may take much longer to leave the system altogether.
Presence of THC
The amount of THC varies according to weed types and quantity. So, if the THC levels are low, it will be easier for your body to expel the drug and vice versa.
So, how long does THC stay in the system?
THC can stay in the hair for up to 90 days. Regarding the urine test, THC can be detectable for a month. In your saliva, the compound will exist for 24 hours, and in the blood, it’ll be present for almost 12 hours.
Method of ingestion
Did you know that how a person ingests weed can affect the time it stays in the body? Yes, that’s true. If you are an avid weed inhaler, the THC compound will reach the bloodstream and organs much quicker than if you infected it orally.
Gender and age
This factor will also significantly affect the weed survival time. With age, the body’s processes also slow down, and it might get more challenging for the system to expel the drug efficiently.
Every individual’s metabolic rate is variable depending on their lifestyle and health. Therefore, it will also impact how long weed stays in a person’s body.
How much marijuana do you have to take to fail a drug test?
Again, the level of marijuana in the body significantly depends on the amount of THC in it. Therefore, the test results will vary for each individual based on how much you use the drug.
According to a study published in Forensic sci int., The detectable levels of cannabinoids in the hair range from 3.4 to > 100 pg THC/mg and 0.10 to 7.3 pg THCCOOH/mg hair. If you smoke 1 to 5 marijuana cigarettes on average, you might fail the test depending on usage and quantity.
On the other hand, if you take a urine drug test, the results will return positive if you have more than 50 nanograms per milliliter of THC in the sample. So if you’re not a frequent marijuana user, but the test comes back positive, it means the amount of THC in the drug is high.
How Can You Beat a Hair Follicle Drug Test?
You can use a few methods to clean your system from THC in record time before undergoing the follicle tests. One of those is hair follicle drug testing shampoo. Now there is a ton of detox shampoos available but don’t get overwhelmed with them. You have to choose the best one to pass.

These home remedies only work if you stop taking drugs while you are on the detox program. To pass the follicle test you must refrain from using drugs for 3 months. So, make sure you are patient enough to wait a long period before you can use weed.
If you still want to know how to pass a drug test then do the following. Remember these remedies might take some time to work. So, if you do have time before you are scheduled to take the test then use the described methods. Otherwise, we recommend you use detox shampoos to pass a follicles drug test.

Do you need treatment for marijuana addiction?
Marijuana has many stress and anxiety-relieving benefits, but at the end of the day, it’s still a drug. If you believe you are addicted to smoking or ingesting marijuana, it’ll be wise to seek treatment. Otherwise, it can end up harming your health and daily life.
The frequency and duration of the treatment greatly depend on the level of addiction. If you’re a new user but wish to leave the drug, you can do that at home with the support of family and friends. But, drug abuse and addiction cases need to be taken care of by proper professionals and require medical assistance.
There are many rehabilitation centers for hard-core addicts to bring them back to the real world. So, whether you need treatment or counseling for your addiction depends on the observation and advice of your physician.
The initial period will be the hardest, no matter how to deal with the addiction. Marijuana, like any drug, develops dependency in the human body. Therefore, withdrawal symptoms can be challenging and complex. But, as time passes, breaking the addiction slowly becomes easier.
