Hair drug testing, or hair follicle drug testing, is a scientific approach to identifying drug use through the examination of hair specimens.

How it works:

• Drug enters bloodstream: Once drugs are used, the substances and their metabolites enter into the bloodstream.
• Drugs reach hair follicles: Due to the blood vessel in each hair follicle, drugs travel from the bloodstream into the hair follicle.
• Drugs get trapped in hair: While the hair extends, the trace chemical compounds become embedded in the hair strand's cortex.
• Hair sample collection: Hair is sampled, usually from the scalp (or body hair if insufficient head hair is available).
• Lab analysis: The collected hair sample undergoes laboratory testing.
  • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) is performed to detect drug metabolites.
  • Confirmation: When the ELISA test is positive, a more thorough confirmation test, like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid - Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), verifies the presence of drug metabolites and dispels false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can indicate drug usage for up to 90 days, unlike urine tests with a shorter span.
• Difficulty to cheat: Cheating on a hair drug test is extremely challenging, enhancing result accuracy.
• Provides historical data: It can reveal a drug use pattern over time, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs require about 5-7 days to become traceable in hair.
• Cost: Hair drug tests typically carry higher costs than other testing methods.
• Variations in results: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentrations in the hair.

Note: Frequently branded as "hair follicle tests", the analysis pertains to the hair strand itself, 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.
