Utilizing hair for substance screening has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a chronic diary of alcohol and other substance intake, capturing biomarkers within the fiber structure of the hair as it develops. When sampled near the scalp, hair can present an approximate three-month window for detecting alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches containing about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp is expected to yield 100mg of hair, which is optimal for both initial screening and subsequent confirmation. For EtG enhancements and/or analyses beyond 10 panels, a sample weighing 150mg is advised. It's suggested to weigh the sample using a jeweler's balance. In cases where scalp hair isn't available, a similar volume of body hair can be utilized. Referring to head hair solely means scalp hair, whereas body hair includes all other types such as facial and axillary.
Process Overview
The laboratory methodology for processing drug test samples encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially logged into a laboratory's framework. This phase confirms the sample was securely sealed and transported, assigns it a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data recording not covered by an electronic custody system.
Screening entails a preliminary rapid assessment for illicit substances. While Screening is an affordable method to exclude drug presence in most samples, any positive result from this phase needs validation for legal acceptability. Samples returning presumptive positives in Screening call for further validation.
Should a sample yield a presumptive positive in Screening, additional hairs from the primary specimen are readied for Extraction. This process entails securing drugs from hair at much-reduced concentrations compared to other techniques (for example, urine or oral fluids), marking hair drug screening as an intricate procedure.
Positive outcomes from Screening warrant a Confirmation process utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing as necessary prior to confirmation. Every step from Accessioning through Confirmation is scrutinized under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

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.
