Hair drug screening, commonly referred to as hair follicle drug screening, is a methodical approach used to identify drug usage by evaluating hair samples.

How it works:

• Drug enters bloodstream: When drugs are consumed, the substance and its metabolites (breakdown products) make their way into the bloodstream.
• Drugs reach hair follicles: Since each hair follicle has an associated blood vessel, drugs are transported from the bloodstream into the hair follicle.
• Drugs get trapped in hair: As hair extends, these trace chemicals embed themselves into the hair's cortex.
• Hair sample collection: A hair sample is obtained, usually from the scalp (or body hair if scalp hair is insufficient).
• Lab analysis: The collected hair sample is dispatched to a lab for examination.
  • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) test is undertaken to screen for drug residues.
  • Confirmation: If the ELISA test shows positive, a more detailed confirmatory test, like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid-Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), is performed to verify the presence of drug residues and eliminate false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug consumption up to 90 days prior, unlike urine tests which have shorter detection durations.
• Difficulty to cheat: It is quite challenging to deceive a hair drug test, enhancing result reliability.
• Provides historical data: It offers an overview of drug use patterns over time, not just recent consumption.

Limitations:

• Cannot detect recent use: It requires approximately 5-7 days for drugs to become traceable in hair.
• Cost: Hair drug tests tend to be costlier than other drug testing techniques.
• Variations in results: Elements such as hair color and individual differences in hair growth can affect the drug metabolite concentration in the hair.

Note: While commonly termed "hair follicle tests", the examination actually assesses the hair strand and not the follicle beneath the skin.

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.
