Hair analysis has emerged as a significant method for identifying the use of drugs and alcohol. It offers a prolonged timeline of drug and alcohol consumption by capturing biomarkers within the fibers of the growing hair strand. When the sample is taken adjacent to the scalp, hair can provide up to a roughly three-month window of detection for substances like alcohol and other drugs. The collection process for hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch lock consisting of approximately 200 hairs (comparable to a #2 pencil in size) closest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For tests involving EtG, additional analyses, or assessments exceeding ten panels, 150mg is recommended. We advocate weighing the sample on a jeweler’s scale. Should scalp hair be unavailable, a similar volume of body hair can be used. In our context, head hair pertains exclusively to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The four core steps in the laboratory evaluation of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's system. This process verifies that the sample was sealed and dispatched correctly, assigns a randomized LAN (Laboratory Accessioning Number), and completes any further data input not covered by a digital chain of custody system.
Screening serves as a preliminary assessment for drug presence. Although Screening is an economical approach to exclude drug usage in the majority of samples, a test positive result must be authenticated to be permissible in legal proceedings. Any samples that are presumptively positive during Screening require additional confirmation.
If the Screening stage results indicate a presumptive positive, further hair is retrieved from the initial sample and readied for Extraction. This phase involves extracting drugs from the hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which is why hair drug screening is considered the most challenging technique to execute.
Confirmatory testing of any positive screened samples is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples that are considered presumptive positive undergo washing before confirmation when necessary. The laboratory procedure ranging from Accessioning to Confirmation is audited under the guidelines of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: While commonly known as "hair follicle tests", the assessment targets the hair strand rather than 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.
