Remember, it takes five to 10 days for “contaminated” hair to break through to the surface of your scalp. A urine drug test, on the other hand, would detect recent marijuana consumption. One issue with the standard urine test, however, is the duration of metabolites that are deposited in the urine. Alcohol in particular has a very short life, and can lose effectiveness for detection in as little as 90 minutes. All of our tests are analyzed by certified labs like LabCorp or Quest Diagnostics.

Blood tests are more invasive, but they’re also more resistant to manipulation and can provide an accurate snapshot of current substance use. When a drug is consumed it leaves behind trace remnants known as “metabolites” in the blood stream that then become deposited in various portions of our physiology. These metabolites, however, have a lifespan for the period in which they remain detectable to certain testing methods and scientific instruments.

The GC/MS also guards against false-positive results caused by foods like poppy seeds or hemp seeds. A hair drug test detects a pattern of repeated drug use over the last 90 days. Because hair growth rates vary from person to person, this test can’t accurately determine when in the 90 days drugs were used. A negative result indicates that you haven’t engaged in illicit drug use over the past 90 days. While a urine drug screen can detect if you’ve used drugs in the last few days, a hair drug test can detect drug use in the past 90 days. A hair strand drug test screens for illicit drug use and the misuse of prescription medication.

It is important to note that this is an initial authorization for hair testing but regulations and guidelines still need to be established by the Department of Health and Human Services (HHS). The Law requires HHS to issue guidelines no later than 1 year from the date of enactment. It will be interesting to see if hair drug testing becomes a reality for the DOT program as early as January of 2017. Other industries that have embraced hair testing include, but are not limited to, the oil and gas industry, the gaming industry, and the auto manufacturing industries.

For example, cannabis has a cut off level at 1 pg/mg, whereas opioids have a cut off level at 500 pg/mg. Any sample that goes over these levels will produce a positive result on a hair follicle test. Compliance with regulations, such as anti-doping tests in sports or legal proceedings like child custody cases, often necessitates supervised testing to uphold fairness and credibility. Additionally, supervised testing reduces the risk of false negatives, ensuring that individuals with recent drug use are correctly identified. Employing specialized shampoos like Old Style Aloe Toxin Rid or Zudot Ulrta Clean may be considered as additional measures to support accurate and reliable testing outcomes. In people who did not admit to drug use, urine testing was more effective at picking up cannabis and benzodiazepines, and hair testing was better at detecting cocaine and oxycodone.

How Far Back Do Hair Drug Tests Go?

It is the period in which the user used drugs that determines the outcome of the hair follicle drug test. Whether a person used once or 50 times in a three month period, the hair follicle drug test will indicate that drug use. This hack only has a 40% success rate if you find it on some internet drug detox forum discussing efficient ways to pass hair drug tests.

A unique thing about a hair sample is that it’s not simply a negative result or a positive result. The lab will look at the hair growth pattern and analyze it to show drug use patterns. The results can show both when you started over the last 90 days and how often you used the drug. It is especially helpful for non-illicit drug use, like in states where marijuana is legal, as the testing process can reveal if you stopped using a drug pre-employment. A hair follicle drug test generally looks for illegal and prescription drug abuse.

There’s also the risk that the drug test collector might notice the damage to your hair and scalp and choose to take samples from other parts of your body. This is why marijuana can be detected in urine for a much longer period, especially in heavy users – sometimes months after the last usage. So, drugs and their metabolites circulating in your blood can get into the hair follicle and become part of the newly formed hair.

This means that the results are not legally binding and could not be used in a court of law. However, it does make it easier to try and fool the testing laboratory. Another person’s hair sample could easily be sent in for testing under your own name. In the same way, fake hair or your pet’s clippings could be submitted. However, all hair samples are typically visually inspected on arrival at a lab.

You will not be able to entirely remove the molecules from your hair strands, and you put yourself a great risk of being caught attempting to defraud the test. While laws vary from state to state, you could face legal actions, fines, or imprisonment. Hair follicle drug tests can determine whether a person has been using certain substances within the past 3 months. However, these tests cannot pinpoint the exact date of drug use because hair growth rates can vary widely among different people. Prescription medications and certain foods, such as poppy seeds, may contain compounds that might lead to false positive results. Hair samples undergo a two-step process to ensure accurate test results.

A positive result means the drug or metabolite was found in the hair sample. All laboratories have no standard positive cutoff values, which may vary among labs. A hair follicle drug test is one way to screen for recreational drug use or prescription drug abuse. A section of hair, about 200 strands, is sent to a lab for testing.

Hair drug tests can identify drug use up to 90 days prior to the test date. That’s because the chemicals from the drugs that end up in your bloodstream become part of the hair cells as your hair grows. A urine drug test is used to test for drug use over the three days preceding the test. A hair drug test is the only drug test that can detect repeated drug use up to 90 days prior to the test.

Hair drug tests may not be appropriate for determining recent drug use. That’s because it may take five to seven days for the drugs to be identifiable through a hair test. To guard against a false positive, laboratories conduct two tests.
