Hair Follicle Drug Testing

How Hair Follicle Drug Testing Works

When you’re looking for “hair follicle drug testing results” there a few key concepts to understand: The process is done by collecting a hair sample from the head or body. It is then analyzed for the presence of drugs, or for the byproducts of drugs. Some individuals try to beat this test by coming to the testing site with their heads shaved. Since the hair can come from anywhere on the body, this trick doesn’t work. That said, hair from different parts of the body differ in how fast they grow, so results can vary depending on where the hair was located.

Drugs We Test for Using Hair

Hair follicle screening can reveal the presence of cocaine, marijuana, codeine, morphine, 6-acetylmorphine, amphetamines, and phencyclidine (PCP). It may also find oxycodone, oxymorphone, hydrocodone, and hydromorphone.

Length of Time Hair Follicle Analysis Can Cover

A hair test using a 1 ½-inch hair may tell you whether the person has done any drugs in the last 90 days. Thinking of this another way, you can ask for a test up to 90 days after a person has ingested drugs.

Determining Current Impairment

It takes anywhere from five to ten days for drugs to reach the hair, so this test is not good for finding out if someone took drugs more recently than that. This means you can’t use hair follicle testing to discover present impairment.

Eliminating Environmental Contaminants

Many worry that smoke from marijuana can get in the hair, meaning that just being around it could result in a positive test result for someone who wasn’t smoking. We test for metabolites, the byproducts of marijuana. These are produced in the body, so only person ingesting marijuana will have the associated metabolites.
