The hair follicle drug test is the most accurate drug test out there. It all has to do with the biological processes taking place in your body. Urine and blood, for instance, are renewed constantly, but the hair that grows on your body lasts for a long time. This means that your hair can store information on your drug use history dating several months back in time. As far as the history of drug use is concerned, most lab tests can detect heavy usage of drugs within the last 90 days. This is the longest duration for which a drug test can spot drug use. An interesting fact about hair follicle drug test is that they can accurately say, with approximation, when the last heavy use of drugs has occurred. The upside is that the lab can tell you have been clean lately, but this probably won’t work to your advantage.
How long does cannabis stay in your hair?
It takes approximately 5 days for marijuana to show up in your hair it can continue to be detectable through a hair follicle drug test for several months. The presence of Marijuana and other drugs in your hair can be understood by this basic principle. Marijuana is ingested in your body and circulates through the blood stream into your blood, urine, saliva, and into the hair follicles via the bloodstream. The drug metabolites that are deposited into your hair follicle are entrapped in the hair shaft as it grows out from your hair follicle. The average growth rate for hair is approximately .5 inches per month. Drug testing labs test for toxin metabolites trapped in the shaft core. Historical drug use can be measured based on the length of your hair sample from your scalp line but a specific timeline of usage is not possible. They cannot tell the difference between THC metabolites introduced two weeks ago from metabolites introduced two days ago. Drug metabolites stored in your hair are chemical and structurally stable in your hair shaft core, they can’t simply be washed, scrubbed or bleached out with conventional shampoos or cleaners. Only medical grade hair detoxification shampoos can remove the traces of drugs and the metabolites they produce from your hair.
What happens during the testing process?
Once you get to your testing location, someone will get a tiny hair sample by cutting it from either the back of your scalp or the top of your head. Then they will put the sample in a sealed container. They will usually take about 1.5 inches of hair since most people grow about 1-2 inches of hair every 90 days. They are looking to take a 90-day sample.
The next step is to take your sample to a lab and have it tested for trace elements. It doesn’t take long for your results to come back. Expect to know if you passed or failed within 3 days.
Can they test body hair? What if I have short hair or am bald?
Hair follicle drug test samples can be collected from several head location and combined to get the required amount of hair sample for testing. The preferred location is to take it from the crown of the skull however if your head hair is too short, body hair can be tested instead. If body hair is used the time frame represented by the test is approximately one year due to the different growth pattern in hair below the neck. While body hair is generally acknowledged as representing a more distant time frame than head hair, the specific time period of drug usage cannot be identified due to the high variability of growth rates.
