Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. It offers a historical record by capturing biomarkers within the strands as they grow. Close-to-scalp samples allow for a detection period of up to roughly three months for substances like alcohol and drugs. Hair collection is straightforward, adulteration is challenging, and shipping is hassle-free.
A sample measuring 1.5 inches and consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields about 100mg, which is ideal for testing and validation. For EtG, additional testing, and tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for weight verification is suggested. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. Our reference to head hair is specifically about scalp hair, while body hair includes other types (facial, axillary, etc.).
Process Overview
The process in a laboratory for drug test results consists of Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial intake of a sample into the lab system, ensuring the sample’s seal and shipment were correct, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data not covered by an electronic chain of custody.
Screening is the preliminary assessment for potential substance use. While cost-effective for dismissing drug use in most samples, a positive screen must undergo confirmation to be legally acceptable. Any sample suspected to be positive during Screening must go through secondary validation.
If Screening results are presumptive positive, additional hair is used from the original sample for Extraction. This process extracts substances at lower concentrations compared to methods like urine or oral fluid testing, making hair analysis one of the most challenging to conduct.
Positive screening confirmations use GC/MS, GC/MS/MS, or LC/MS/MS technologies. Prior to Confirmation, all samples flagged as positive are cleaned as necessary. The process, from Accessioning through Confirmation, adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Drawbacks:
Note: Despite common terminology as "hair follicle tests", these tests actually assess the hair strand, not the follicle beneath the scalp.

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.
