Whether you’re a newbie or a seasoned cannabis user, this article will provide you with an overview of Cannabidiol (CBD), THC, Bioavailability, and Hair follicle tests. Read on to find out what these tests mean for your health and your job. Until then, you can focus on making informed decisions.


In order to extract cannabidiol from hair, a protocol involves overnight methanol extraction. The hair is placed in an ultrasonic bath for a minimum of four hours, and the methanol is then removed and dried in a centrifugal concentrator. This procedure is designed to extract cannabinoids from the hair, while also removing other drug compounds. Next, the hair is digested in a solution of sodium hydroxide. The combined extracts are then dried at 30 degrees Celsius for one hour, and then a buffer solution is added.

The method cannot determine specific timing of drug use. For example, it cannot distinguish THC metabolites that were introduced two weeks ago from those introduced just days ago. Because THC binds to cells and tissue surrounding the root of hair, it can’t determine the exact time period of use. However, it can detect cannabinoids that remain in the hair follicles.


It is not known how long does THC stay in hair florcles, but it may be several weeks. Usually, the hair is sampled 1.5 inches from the scalp. Hair grows at a rate of 0.5 inches per month, so it is possible for THC to remain in hair for up to 90 days. This amount of time means that it is possible for THC to remain in the hair of someone who has never smoked pot before.

When smoked, THC enters the bloodstream in a matter of minutes, and the effects last up to two hours after ingestion. However, the effects can vary by person. The duration of cannabis stays in a person’s body depends on a number of factors. The average person can remain high for several months after inhaling cannabis, while people who use pot regularly may have higher THC concentrations in their blood.

Hair follicle test

Many CBD users wonder if it shows up on drug tests in their hair. The short answer is that CBD doesn’t show up in hair follicle tests. While THC is not present in trace amounts, it will trigger a false positive test result. If the amount is too high, CBD can cause a false positive, but there are many other cannabinoids that can be detected in your hair.

Hair follicle tests have a greater detection window than urine tests. This means that a person who uses marijuana, cocaine, or opiates may have traces of the drug in their hair several months before they submit a hair follicle drug test. Therefore, the testing results may not reflect the current situation. However, the tests can be useful for detecting drug use if it’s detected in the body at an early stage.


The bioavailability of CBD and THC in hair follicles was investigated by comparing samples collected before and after hemp oil application in volunteers. Both THC and CBD were found in the samples from the proximal 0-3 cm section. Results were presented in terms of ng/mg, with ND indicating not detectable. The THC and CBD levels in volunteer 4 were higher before and after the application.

The amount of CBD absorbed from the follicles is limited by its low solubility in the intestine. After entering the body, most of CBD is metabolized in the liver, and only a small proportion of CBD makes it to the bloodstream. However, the company that produces CBD uses various methods to enhance its bioavailability in the follicles, including a special peptide.

Drug test results

In drug tests, hair follicles can reveal traces of the cannabinoid THC or its metabolites. Hair follicles retain the metabolites five to 10 days after exposure to the drug. However, light-colored hair does not retain these metabolites as well as darker-colored hair. Fortunately, the drug metabolites can still be detected in hair after 72 hours.

When the hair follicles are subjected to a test for marijuana, the test will look for tetrahydrocannabinol, or THC. THC is the psychoactive component of marijuana, and can cause impaired judgment. Drug tests look for THC, not CBD. In addition, full-spectrum cannabis products may contain trace amounts of THC. Using such a product can lead to a positive result.
