How To Pass A Hair Follicle Drug Test For Marijuana (1)

When you smoke (or ingest, vaporize, or otherwise) marijuana, THC, the active chemical in cannabis, is broken down and metabolized into your bloodstream. It takes time for these bits—called metabolites—to be absorbed and broken down by your body, long after your high has dissipated. A drug test measures these metabolites that can still be found in your system.

There are three primary ways that you can get drug tested: Urine, Blood, and Hair, each with their own strengths and weaknesses.

  • Urine drug tests are far and away the most common. Depending on the frequency of your usage, urine drug tests can test positive for as little as 3 days for occasional smokers and up to 30 days or more for chronic chronic users.
  • Blood tests are used much less frequently than urine tests and really only have reliable results within 1-2 days. Generally speaking, blood tests are often utilized in laboratory settings or in cases to determine very recent drug consumption

Hair Follicle Drug Tests: How Long Does Marijuana Stay in Your Hair Follicles?

Last, and most feared, among the usual drug tests is the hair follicle drug test, or hair drug test, where a number of hairs are taken from the crown of your head and are put through two different tests to determine a history of drug use with a higher rate of accuracy over a longer period of time. If you were wondering What is the difference between a hair drug test and a hair follicle drug test? they are interchangeable terms for the same drug test.

How Far Back Does A Hair Follicle Test Detect Drugs?

Marijuana can stay in your hair for 6-12 months, but testing labs only test for the last 90 days worth of hair growth. Labs can’t test your head or body hair if your head hair is too short. These tests are getting more popular with higher paying jobs and high-profile employers. The length of the window of detection for hair follicle drug tests can last up to 90 days. As stated above, metabolites enter your bloodstream where they are processed by your organs and broken down. In the case of your hair, the THC metabolites become part of the cellular structure of your hair as it grows, therefore a hair follicle drug test essentially uses your hair as a rough timeline for drug use within the most recent three months.

The hairs are then sent to a laboratory where they are washed and cleaned of any environmental contaminants. The hair is first tested in a simple pass/fail of drug use. If negative, that’s that. If positive, then a second test using gas chromatograph is administered where the frequency and type of drug use can be detected.

Because of the length of the window of detection in hair follicle drug tests, it can take up to 5 days for your hair to grow enough for THC metabolites to be detectable.

Hair suitable for the hair follicle test is preferably taken from the crown of the head. If the hair is too short, body hair may be taken for analysis, however, these results are far less reliable because hair growth rates can vary wildly person to person.
