How Long Does CBD Stay in Your Hair? – The Full Guide

YOU SMOKED with your friends last weekend, but in the cold harsh light of You might be regretting Monday, particularly if your employer uses drug hair tests. Read the post to find out how long does CBD stay in your Hair?

In general, substances such as CBD can be detected in hair up to about 3 months after they were last taken. A hair test is unlikely to detect even minute amounts of THC.

Does CBD Show Up in a Hair Follicle?

Can CBD be detected using a hair follicle test? Stop us if you’ve heard this before, but workplace hair follicle tests typically do not look for CBD; instead, they look for that time-tested drug THC-COOH. Therefore, CBD won’t be detected in a hair follicle drug test used in the workplace. THC will, though.

What Can Cause a False Positive Hair Follicle Test?

The tester will take a small sample of hair from the subject’s scalp during the test, and the sample will be sent to a lab for overnight testing. Prescription drugs and particular foods, like poppy seeds, may contain ingredients that could cause falsely positive results.

How Does Weed Get in My Hair, Anyway?

When you consume, vape, or smoke marijuana, all you’re really doing is allowing the drug’s active ingredients to enter your bloodstream. These cannabinoids travel through your bloodstream to the cannabinoid receptors on your body’s cells, where they bind and cause their effects. The majority of tests look for cannabinoids, which are the psychoactive THC’s metabolites, along the way as they enter the blood vessels that supply the cells of the scalp. THC crosses the gap and enters the matrix, which is where actual hair growth takes place, at the point where the vessel and follicle cells known as the hair papilla meet. Over the following few weeks, the root’s hair sprouts upward, carrying THC past the scalp, where it is now acceptable for testing for the following three months.

How Does Hair Testing Detect THC?

Once your hair has been collected, it is washed to remove any external impurities, chopped up, and then digested in a solution meant to break it down into its components—primarily the protein keratin and any other substances that manage to make their way into the hair shaft. Normally, that solution is run through an ELISA (enzyme-linked immunosorbent assay) screen, a lab technique that employs particular antibodies to bind the desired target molecule, in this case, THC. (THCA, a THC direct metabolite, to be exact.)

In the event of a positive test, a second examination using methods such as gas chromatography and/or mass spectrometry is typically conducted on a sample of the same hair. These techniques, known as GC/MS and GC/MS/MS (tandem MS), are more accurate, more involved techniques that scan the sample for the “molecular signature” of the target compound.

Final judgment is determined by the chemical’s final concentration in a sample of hair. The “confirmatory level” of The quantity of THCA used by Quest Diagnostics is 0.1 picograms per milligram of hair. Anything above that is pretty much a guarantee that you’ve used marijuana within the last three months.

How Your Body Processes CBD and Factors That Affect How Long CBD Stays in Your System

The length of time CBD remains in your system and its effects on you are both influenced by a variety of different factors. Not everyone experiences it for the same amount of time or can detect it.

It can depend on:

• Physical factors and genetics, such as your metabolism, age, and weight
• The last time it was taken
• Dosage
• Frequency of use

Because CBD is fat-soluble, your body’s fat cells store it instead of its water cells. Its rate of metabolization is therefore influenced by your Body Mass Index (BMI). It will take longer to leave your system if your body mass and weight are higher.

Your method of intake can influence how it affects you as well as for how long it lasts. Popular methods and forms of CBD include:

• Oils
• Vape
• Dietary supplements
• Edibles
• Dried flower

CBD enters your bloodstream quickly if you vape or smoke dried flower forms of the substance. Thus, in this way, CBD’s effects on the brain manifest themselves more quickly.

The effects of taking a CBD-containing dietary supplement or edible won’t be felt right away. How quickly you experience the effects can depend on your metabolism and diet. However, symptoms frequently appear an hour after you’ve eaten it.

The effects, however, can typically last one to three hours, regardless of how you take it.

Conclusion

Hair tests are renowned for their ability to detect drugs for a long time. For up to three months after administration, these tests are able to identify the THC metabolites in CBD. Hair tests for THC and CBD, however, are also extremely rare.
