Hair drug testing, commonly referred to as hair follicle drug testing, is a scientific approach to identifying drug use by examining hair samples.

How it works:

  • Drug enters bloodstream: When an individual consumes drugs, both the substance and its metabolites (breakdown products) are introduced into the bloodstream.
  • Drugs reach hair follicles: Each hair follicle has its own blood supply, allowing the drugs to transfer from the blood to the hair follicle.
  • Drugs get trapped in hair: As the hair develops, small amounts of these chemicals are incorporated into the hair strand's cortex.
  • Hair sample collection: Hair is sampled, usually from the head (or body hair if head hair is inadequate).
  • Lab analysis: The collected hair is sent to a lab for examination.
    • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) test screens for drug metabolites.
    • Confirmation: Should the ELISA test return positive, a more precise confirmation test, such as Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), is performed to verify drug metabolites and eliminate false positives.

Advantages of hair drug testing:

  • Long detection window: Hair drug testing can reveal drug use for as long as 90 days, unlike urine tests which offer a shorter detection period.
  • Difficulty to cheat: It is notably challenging to cheat a hair drug test, resulting in more reliable outcomes.
  • Provides historical data: It can demonstrate a timeline of drug use extending over a duration, not merely recent ingestion.

Limitations:

  • Cannot detect recent use: Drugs can only be detected in hair after approximately 5-7 days.
  • Cost: Hair drug tests tend to be costlier than other drug testing techniques.
  • Variations in results: Elements like hair color and personal differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the examination evaluates the hair strand and not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
Hair testing provides a longer look-back period than urine testing, making it useful when you need to demonstrate ongoing abstinence or identify repeated/recent substance use patterns over time rather than just recent exposure. It is frequently selected for legal, compliance, and custody-related documentation.
A small section of hair is cut by a trained collector in a discreet, controlled manner. The sample is sealed, documented, and sent to the laboratory under established chain-of-custody procedures so that the results can be defended if they are ever challenged.
